Green ENCASEMENT Coatings is not the name of an individual product, a brand, or a proprietary formulation. It is a defined product category — a classification of coating systems that meet a rigorous, multi-dimensional standard across three integrated

dimensions: environmental responsibility (Green), structural-grade substrate reinforcement (Encasement), and practical accessibility (Coatings). Any coating system meeting all three dimensional criteria qualifies as a Green ENCASEMENT Coating. This document is a reference for the category. It is not an advertisement for any individual product. This category was defined and named by George C. Keefe, MBA, The ENCASEMENT Guy, drawing on 50+ years of field experience across five continents. The standards defining the category are grounded in EPA, NOAA, IBHS, ASTM, LEED, and peerreviewed scientific sources.

Abstract

Hail is the most underestimated destructive force in the built environment — and it is rapidly becoming the most expensive. While hurricanes and wildfires dominate disaster headlines, hail quietly and relentlessly destroys roofs, walls, windows, and building systems across every continent, every season, and an ever-widening geographic range. The numbers are staggering: hail drives 50–80% of all severe convective storm insurance losses, which averaged $42 billion per year in the United States from 2020 to 2024 — more than five times the rate of the previous decade. Munich Re documents that the last three years (2023–2025) produced $208 billion in combined severe convective storm losses globally, while a landmark study published in Nature Geoscience (2026) confirms that very large hail events have increased fastest in Europe since 1950, making this a global and accelerating crisis. For roofs — the primary target of every hailstorm — the damage is both immediate and cumulative: each impact event strips granules, bruises asphalt, fractures membranes, and initiates a deterioration cascade that makes the next event far more destructive. IBHS research published in 2025 found that shingles exposed to even sub-severe hail become approximately ten times more susceptible to damage from subsequent storms. Against this reality, conventional roofing and conventional paint both fail — shingles wear out in 15–25 years even without hail, and paint provides zero impact resistance. This reference document establishes the complete, evidence-based case for Green ENCASEMENT Coatings as the definitive response to the hail threat: both as a proactive protective system that prevents hail damage before it occurs, and as a restoration tool that addresses existing hail damage without replacing roofs that can be preserved and extended. The restoration case is particularly compelling: a Green ENCASEMENT Coating applied to a hail-damaged roof can restore waterproofing, seal compromised granule surfaces, extend service life by 20+ years, and eliminate the embodied carbon, construction waste, and economic disruption of full roof replacement — all at up to 75% lower cost than removal and replacement.

1. Introduction: The Sky Is Falling — And It Has Been for

Decades From my experience over 50 years of protecting buildings and their occupants across five continents, I have watched virtually every form of weather attack a building can face. Wind. Water. Heat. Fire. Salt air. Chemical exposure. Time. All of them are serious. But hail is the one that still surprises people — because it arrives fast, it leaves quickly, and the damage it inflicts is often invisible until it isn't. A hailstorm that passes in 15 minutes can shred the granule protection off an entire roof, compromise every penetration point in a building envelope, crack skylights, destroy HVAC equipment, dent solar panels, and initiate a water infiltration pathway that silently destroys the building's structural components for years afterward. By the time the ceiling stains appear, the rot has spread. By the time the insurer arrives, the claim has grown. By the time the replacement crew appears, the building has already lost years of service life it did not need to lose. The economic reality of hail is now impossible to ignore. Gallagher Re documents that hail drives 50–80% of all severe convective storm losses — making it, not hurricanes, not wildfires, not floods, the single largest category of annual building damage expense in the United States. And as climate change intensifies hailstorm frequency and severity across more regions of the world, the buildings that are not proactively protected with the right technology are going to face an increasingly expensive and punishing future. The solution this document presents is not a complicated one. It is a Green ENCASEMENT Coating — applied to any building exterior, on any substrate — that prevents hail damage before the storm and restores building performance after it. Not a new roof. Not a complete replacement. An engineered, science-backed, field-proven encasement system that delivers what hail demands: high-elongation flexibility that absorbs and disperses impact energy, seamless waterproofing that seals every compromised point, and 20+ years of guaranteed renewable protection that outlasts every hail season.

2. The Science of Hail: How It Forms and How It Destroys

2.1 How Hailstones Form

Hailstones form inside supercell thunderstorms when water droplets are carried upward into freezing air by powerful updrafts, coating ice nuclei in successive layers of ice. Each updraft cycle adds another layer. The stronger the updraft — and the longer the hailstone stays aloft — the larger it grows. The NOAA Storm Prediction Center defines severe hail as hailstones of 1 inch diameter or larger (approximately the size of a quarter). Hail Alley — the region spanning Nebraska, Colorado, and Wyoming — averages seven to nine hail days per year, the highest density in the world. Tornado Alley states of Texas, Oklahoma, and Kansas add thousands more annual hail events.

The velocity at which hailstones strike building surfaces is determined by their size, the wind speed at the time of impact, and the angle of the storm track. A 1-inch hailstone strikes with sufficient kinetic energy to dislodge roofing granules and bruise asphalt mat. A 2-inch hailstone (golf ball size) fractures most conventional roofing materials and punctures single-ply membranes. Hailstones 3 inches or larger — softball to grapefruit size — cause severe structural damage to everything exposed: roofing, siding, windows, HVAC equipment, solar panels, and vehicles. A 19-centimeter hailstone documented in northern Italy in 2023 remains the largest ever recorded in Europe. Under 1 inch (quarter)

Sub-severe by NOAA definition but documented by IBHS to cause cumulative granule loss that makes shingles 10x more susceptible to future damage. Sub-severe hail exposure of just 2 years ages shingles by the equivalent of a decade. [IBHS, 2025]

1 inch (quarter) — SEVERE threshold

Minimum NOAA severe classification. Causes granule dislodgement on asphalt shingles, beginning the UV exposure cascade. Capable of cracking older or weathered roofing materials.

1.5 inches (walnut)

Significant granule loss on standard shingles. Capable of cracking clay tile. Impact-resistant shingles begin to show damage. HVAC fins and solar panel surfaces sustain visible damage.

2 inches (golf ball)

Fractures most conventional roofing materials. Punctures single-ply membranes. Shatters skylights. Cracks fiberglass panels. IBHS: even most impact-resistant roofing materials are not engineered to withstand hailstones over 2 inches.

3 inches (baseball / softball)

Severe structural damage. Punctures metal roofing panels. Breaks HVAC equipment and compressors. Fractures concrete roof tiles. Causes significant structural denting in metal wall panels and cladding.

4+ inches (grapefruit and larger)

Catastrophic impact. Penetrates roofing systems entirely in some cases. Structural damage to building envelope. 4.5-inch hailstones documented in North Dakota (2024). 19 cm stone documented Italy (2023) — European record.

2.2 The Damage Cascade: How One Hailstorm Leads to the Next

The most critical insight from IBHS research published in 2025 in the peer-reviewed journal Frontiers in Materials is one that the roofing and insurance industries are still absorbing: subsevere hail — stones smaller than 1 inch that do not even trigger a NOAA severe hail report — causes cumulative damage that makes shingles dramatically more vulnerable to subsequent severe storms. The research found that just two years of sub-severe hail exposure and natural weathering produced shingles that performed as if they were a decade old. More critically: shingles exposed to this cumulative sub-severe damage became approximately ten times more susceptible to damage when the next severe hail event struck. This means that roofs in hail-prone regions do not simply face a binary event risk — hit hard or not. They face a continuous, escalating vulnerability cycle: each sub-severe event strips granules and bruises mat, reducing resistance; the next moderate event causes more damage

than it would have on a new roof; the subsequent severe event causes catastrophic damage to a roof that would have survived if it had been maintained with proper encasement protection. This cascade is the primary driver of the escalating hail insurance losses documented across the central United States and increasingly in Europe and Australia.

"Hail damage is not a single event with a single cost. It is a cascade — each storm leaving the roof more vulnerable than it found it, until what began as granule loss becomes a leaking roof, then a mold problem, then a structural issue, then a claim that costs ten times what proactive protection would have cost." — George C. Keefe, MBA, The ENCASEMENT Guy | Founder & CEO, Global ENCASEMENT, Inc.

3. The Global Hail Crisis: Not Just a US Problem

North America is what climate scientist Scott St. George of WTW (Willis Towers Watson) calls the hail continent — with the most severe and most frequent large hail events in the world. But hail is a global threat, and climate change is rapidly expanding the geographic reach and severity of extreme hail events. A landmark study published in Nature Geoscience in January 2026 — compiled by researchers from the European Severe Storms Laboratory, Adam Mickiewicz University, and Munich Re — documented the global trend with alarming clarity.

The Global Hail Crisis — Documented Scale and Cost • • • • • •

US insured hail losses: $20–35 billion annually per Gallagher Re. Hail drives 50– 80% of all severe convective storm losses. [Gallagher Re, US News 2024] US severe convective storm losses averaged $42 billion/year from 2020–2024 — more than five times the $8 billion/year average of 2000–2010. [Gallagher Re] Global SCS losses 2023–2025 combined: $208 billion — the peril is now the dominant annual loss driver for global insurers. [Allianz, April 2026] 2025: US thunderstorms alone generated approximately $60 billion in insured losses. [Munich Re, January 2026] 2023: Global severe thunderstorm insured losses reached $71 billion, with Europe alone recording $17 billion — a continental record. [HDI Global, Munich Re] Europe 2023: Hailstorms in northern Italy alone caused losses of $8.6 billion (insured: $6.5 billion) in one series of storms. A 19 cm hailstone — largest ever recorded in Europe — documented in this event. [Munich Re] Nature Geoscience (2026): Very large hail frequency has increased fastest in Europe since 1950. Northern Italy emerging as a global hotspot rivaling the US Great Plains. [ESSL/Munich Re/Nature Geoscience] Climate projections: Frequency of the most damaging large hailstones projected to increase 15%–75% depending on emissions scenarios. [Allianz, April 2026]

Global hail hotspots: US Great Plains, northern Argentina, Uruguay, Paraguay, southern Brazil, South Africa, northern Italy, Germany, Australia's coastlines — all documented high-risk zones.

3.1 Hail Alley and the Expanding Hail Belt

The NOAA Storm Prediction Center documents that the area where Nebraska, Colorado, and Wyoming meet — known as Hail Alley — averages seven to nine hail days per year, the highest concentration anywhere in the world. Texas has consistently experienced the most total hail events of any US state over the last decade, followed by Kansas and Nebraska. Over 2023– 2025, 45% of all severe US hail events were concentrated in the central plains states. But the boundaries are expanding. Climate change is shifting Tornado Alley — and with it, Hail Alley — eastward into the Southeast and parts of the Midwest. Communities that historically experienced low hail risk are now facing multiple damaging events per year. In New Jersey, hail events jumped from 8 in all of 2024-2025 to 42 in 2023 alone. States that never appeared on hail risk maps are beginning to drive meaningful insurance losses. No region in the United States is immune, and the same expansion is documented globally across Europe and Australia.

4. How Hail Destroys Buildings — Especially Roofs

Hail damages buildings through direct kinetic impact and through a cascade of secondary effects that unfold over months and years after the initial storm. Understanding both mechanisms is essential to understanding why proactive protection is so valuable and why restoration after damage is so much better than replacement.

4.1 Roof Damage — The Primary Target

Roofs and roof-mounted equipment — HVAC systems, solar panels, skylights, and communication equipment — are the most commonly damaged parts of any building in a hailstorm, per Allianz's 2026 SCS report. Roofs bear the full brunt of direct downward hail impact, with no shielding from walls or overhangs. The damage mechanisms vary by roofing material: Asphalt Shingles (75% of US residential roofs)

Granule displacement is the primary damage mode. Granules protect the asphalt mat from UV degradation — when stripped by hail, the exposed mat oxidizes and becomes brittle within months. IBHS: roofs with less than 40% granule coverage after a hailstorm face high risk of leaks and premature failure. Even sub-severe hail accelerates this process, making shingles 10x more susceptible to the next storm. Standard shingles have no meaningful hail resistance. Even Class 4 impact-resistant shingles rated by IBHS are not engineered to withstand hailstones over 2 inches.

Single-Ply Membranes (commercial low-slope)

Direct puncture of TPO, EPDM, and PVC membrane systems by hailstones 2 inches and larger. Even non-penetrating impacts create membrane stress concentrations that fail under thermal cycling. Hailstone accumulation can block roof drains, creating ponding water that collapses roof structures — a failure mode that most building codes worldwide did not anticipate.

Metal Roofing

Denting and deformation from impact. While metal roofs rarely puncture from hail, cosmetic damage can be extensive enough to require full replacement under insurance policies — at enormous cost and waste. Paint and coating systems on metal roofs are particularly vulnerable to granule-equivalent impact damage (chipping, cracking, delamination) that exposes the substrate to accelerated corrosion.

Clay and Concrete Tile

Cracking, fracturing, and displacement of tiles by impact from hailstones 1.5 inches and larger. Fractured tiles lose their weatherproofing function and must be individually replaced — a labor-intensive and expensive process. In many cases, hailcracked tiles are not discovered until the first significant rainfall event after the storm.

Built-Up Roofing (BUR) and Modified Bitumen

Surface erosion, granule displacement from cap sheet surfaces, and membrane cracking. BUR systems that have weathered for 10+ years are particularly vulnerable to hail-induced fracture of the surfacing layers.

Spray Polyurethane Foam (SPF)

Impact indentation and surface coating cracking from large hailstones. Without a properly maintained protective topcoat, hail damage to SPF systems allows UV penetration that can degrade the foam rapidly.

Solar Panels and HVAC Equipment

Solar panel glass can be shattered by hailstones 2 inches and larger, requiring replacement at $200–$400 per panel. HVAC condenser fins are readily deformed by any significant hail impact, reducing equipment efficiency and triggering premature system failure.

4.2 Wall and Facade Damage

While roofs bear the direct downward impact of hail, building walls and facades face wind-driven hail that arrives at significant horizontal velocity — sometimes equal to or exceeding the downward impact force depending on storm track and wind speed. This wind-driven component damages: •

Siding panels — vinyl, fiber cement, wood, and aluminum — dented, cracked, or perforated by wind-driven hail, compromising both weatherproofing and structural integrity. Window frames and glazing — hailstones 1.5 inches and above crack or shatter standard glazing; frame seals are compromised even by sub-severe impacts.

Exterior insulation and finish systems (EIFS) — surface coatings cracked and delaminated, waterproofing compromised. Paint and conventional coatings on masonry, metal, and wood — chipped, cracked, and delaminated, exposing substrates to moisture infiltration and corrosion. Roof-wall junctions and flashings — the critical waterproofing interface between roof and wall systems, already the most common point of building envelope failure per the NRCA, made dramatically more vulnerable by hail impact on adjacent materials.

4.3 The Hidden Secondary Damage: Water, Mold, and Structural Decay

The visible damage from a hailstorm is often the smaller part of the total loss. The larger and more insidious cost comes from what happens in the months and years after impact as compromised roofing and wall systems allow water infiltration that: •

Initiates mold growth within 24–48 hours of water contact with insulation and structural materials — CDC and EPA both document the rapid establishment and health impacts of post-leak mold colonies. Causes progressive structural decay in wood framing, engineered lumber, and associated structural elements — a process that begins silently and becomes catastrophic gradually. Damages interior finishes, equipment, inventory, and occupant property through ceiling collapse, wall staining, and floor damage from moisture migration. Creates business interruption — commercial buildings where roof damage forces operational shutdown or relocation add a major indirect cost multiplier to every hailstorm event. Triggers claim disputes — insurance adjusters frequently classify hail damage as cosmetic rather than functional, leaving building owners with the full cost of secondary water damage that follows.

5. The True Cost of Hail: Direct and Indirect Losses

Worldwide

5.1 Direct Costs: The Documented Numbers

The direct cost of hail damage to buildings is now one of the largest and fastest-growing lines in the global natural catastrophe loss ledger. The data from Munich Re, Swiss Re, Gallagher Re, and the Insurance Information Institute is consistent: severe convective storm losses — of which hail drives the majority — have increased dramatically over the last 25 years, with no indication of reversal.

5.2 Indirect Costs: The Hidden Multiplier

For every dollar of direct hail damage documented in insurance claims, multiple additional dollars of indirect cost flow through affected communities, businesses, and building owners that never appear in catastrophe loss statistics. These indirect costs are real, recurring, and preventable. •

Business interruption: Commercial buildings forced to close during roof repair or replacement lose days, weeks, or months of revenue. Industrial facilities may face production interruption costs that dwarf the repair cost itself. Occupant relocation: Residential and commercial occupants displaced during hail damage repair face hotel, storage, and transitional living costs — commonly covered under loss-of-use insurance provisions but adding significantly to total event cost.

Secondary water damage remediation: Hail-compromised roofing that allows water infiltration generates mold remediation, structural repair, interior finish replacement, and equipment loss costs that typically exceed the original roofing repair cost. Insurance premium escalation: National average home insurance premiums have risen 46% since 2021, with hail-prone states seeing even sharper increases. Nebraska premiums rose 25% in a single year (2025). Oklahoma's average wind and hail deductible reached $6,044. Nebraska insurers paid $1.36 for every $1 earned in premiums in recent seasons. [Insurify, 2026] Reduced property values: Buildings with documented hail damage history, recurring roof replacement cycles, or evidence of water infiltration suffer measurable reductions in appraised and market value — a cost that accrues to every owner whether they file a claim or not. C&D waste and embodied carbon: Every roof replacement generates construction and demolition waste. The EPA documents that C&D debris constitutes approximately 600 million tons annually in the US alone. Each unnecessary roof replacement contributes to this waste stream — and replaces not only the physical material but the embodied carbon invested in manufacturing and installing the original roof.

6. The Insurance Crisis: Hail's Growing Role

The Insurance Information Institute documents that hail is now the primary driver of the home insurance crisis spreading across the central United States — states that never previously faced the insurance availability and affordability challenges associated with coastal hurricane risk or Western wildfire risk. In Nebraska, Kansas, Colorado, Oklahoma, Missouri, and Texas, hail is doing to insurance what hurricane risk did to Florida: making coverage increasingly unaffordable, unavailable, or exclusionary. •

65% of homeowners surveyed reported that severe weather had damaged their roofs. Among them, 43% identified hail as the primary cause — making hail the leading roof damage source. [Insurify, 2026] 72% of homeowners surveyed said they would make sacrifices to lower their insurance premiums. 50%+ said they would invest in home improvements to mitigate climate risk if it reduced insurance costs. [Insurify, 2026] National average home insurance premiums risen 46% since 2021. Projected to rise another 4% in 2026. [Insurify, 2026] In hail-prone states, insurers are increasingly using actual cash value (ACV) settlements for older roofs rather than replacement cost coverage — leaving building owners with a gap between the claim settlement and the actual replacement cost. Some insurers have introduced wind and hail exclusions or separate higher deductibles in high-risk states — effectively shifting the cost burden back to building owners.

"The question is clear: will we continue investing billions in cleanup and rebuilding after every hail season — or will we embrace proactive solutions

that prevent damage in the first place? Green ENCASEMENT Coatings offer the proactive path. And for buildings already hit, they offer restoration that avoids the replacement cycle entirely." — George C. Keefe, MBA, The ENCASEMENT Guy | Founder & CEO, Global ENCASEMENT, Inc.

7. Why Conventional Roofing and Conventional Paint Fail

Against Hail The roofing industry's response to the hail crisis has centered on incremental improvements to existing material categories — impact-resistant asphalt shingles, metal panels, and tile systems. These improvements are real and valuable. But they do not solve the fundamental vulnerability of any roof system that relies on discrete components held together by fasteners, sealed with caulk, and maintained with paint. •

Asphalt shingles: Even Class 4 impact-resistant shingles rated by IBHS — the highest classification available — are not engineered to withstand hailstones over 2 inches. In the US, 2024 saw its third-highest count of reports of hailstones larger than 2 inches. Impact-resistant shingles cost 10% more than standard shingles but still face the same granule loss cascade, still have a 15–25 year service life, and still require full replacement when that life is exhausted. Metal panels: Dent without puncturing in most hail events, but the cosmetic damage can trigger full replacement under insurance policies — at enormous cost and waste. The coating on metal roofs chips, cracks, and delaminates under hail impact, exposing the substrate to the accelerated corrosion that is the primary metal roof failure mode. Conventional paint as protection: Conventional architectural paint provides zero hail impact resistance. It sits on the surface as a thin, rigid film. Under hail impact, it chips and cracks. Under the subsequent thermal cycling, the cracks propagate. Under the subsequent rainfall, the cracks become water infiltration pathways. Every hail event accelerates the conventional coating's failure timeline. The seam problem: Every conventional roofing system — shingles, panels, tiles, membrane — has seams. Every seam is a potential failure point under hail impact, wind load, and thermal cycling. Hail that misses the field of a metal panel often lands on a seam fastener or joint edge — the highest-stress point in the assembly.

"Paint sits on top of a surface. Encasement becomes part of it. That is the difference between cosmetic coverage and actual protection. Against hail, the only meaningful defense is a seamless, monolithic membrane that absorbs impact energy and has no seams for the storm to exploit." — George C. Keefe, MBA, The ENCASEMENT Guy | Founder & CEO, Global ENCASEMENT, Inc.

8. Green ENCASEMENT Coatings: Prevention Before the

Storm A Green ENCASEMENT Coating applied to a building exterior before a hail event provides a fundamentally different level of protection than any conventional paint or discrete panel assembly. The cross-link bonding technology, high-elongation polymer matrix, and seamless monolithic membrane architecture together create a hail-resistant building envelope that addresses every failure mode that hail exploits in conventional systems.

8.1 How Green ENCASEMENT Coatings Resist Hail

High-Elongation Impact Absorption

>= 200% elongation at break per ASTM D412 at temperatures from -10 to +70 degrees C. When a hailstone strikes a high-elongation polymer membrane, the impact energy is absorbed and dispersed across a wide area rather than concentrated at the impact point. The membrane deforms and rebounds — maintaining waterproofing integrity where a rigid brittle coating would crack and delaminate. This is the same principle that makes rubber absorb impact rather than shatter.

Seamless Monolithic Membrane

Zero seams, fastener holes, or panel joints across the entire protected surface. There are no stress concentration points for hail to exploit, no joint edges for wind-driven hail to penetrate, and no seams for water to infiltrate after impact. The entire building envelope becomes a single continuous protective surface.

Cross-Link Bond Adhesion

Pull-off strength >= 200 psi per ASTM D4541. The membrane is bonded to the substrate at the molecular level — it cannot be lifted, peeled, or separated by hail impact forces. Even the largest documented hailstones cannot mechanically separate a properly applied Green ENCASEMENT Coating from its substrate.

100% Waterproofing After Impact

Even where a Green ENCASEMENT Coating membrane is temporarily deformed by hail impact, its waterproofing integrity is maintained — unlike asphalt shingles (granule loss) or metal roofing (coating delamination), which begin losing waterproofing function from the first significant impact. Simultaneous breathability (ASTM E96) prevents moisture trapping.

Solar Reflective Formulation

White and light-colored formulations achieve Solar Reflectance Index >= 78 (ASTM E1980), reducing surface temperatures by 50– 80 degrees F and cutting cooling loads 15–40%. This thermal load reduction also reduces the thermal cycling stresses that fatigue conventional coatings and accelerate hail damage accumulation.

Class A Fire Rating

ASTM E108 / UL 790 Class A fire resistance — the highest available classification. For buildings in regions where hailstorm conditions coincide with lightning-ignition fire risk, the Class A rating provides simultaneous storm and fire protection.

20-Year Guaranteed Renewable Service Life

4 to 6 times longer than conventional paint (3–5 year failure cycle). A single Green ENCASEMENT Coating application protects

through multiple hail seasons. Renewable with recoat — no removal of the substrate required.

8.2 The Pre-Hail Application Protocol

Green ENCASEMENT Coating application for hail prevention follows the standard encasement protocol: substrate inspection and preparation, surface cleaning, primer coat where required, full-coverage encasement application at specified film thickness to ensure >200 psi adhesion and >200% elongation throughout. Application with standard airless spray, brush, or roller. Water cleanup. No specialized equipment or crew certification required. The critical performance decision is film thickness. A minimum specified dry film thickness (DFT) must be achieved uniformly across the entire surface — including corners, penetrations, flashings, and edge conditions that conventional coatings routinely underfill — to deliver the elongation and impact resistance performance documented in the ASTM testing protocols. The manufacturer's current TDS must be consulted for specific application rates and DFT requirements for the intended hail exposure zone.

9. Green ENCASEMENT Coatings: Restoration After Hail

Damage This is where the Green ENCASEMENT Coatings case becomes especially compelling — and especially distinct from every other building product category. For a roof that has already been struck by hail, the conventional answer is expensive and wasteful: strip the damaged roofing, haul the material to a landfill, manufacture new roofing, transport it, install it, and start the clock on a new 15–25 year replacement cycle. Green ENCASEMENT Coatings offer a fundamentally different answer.

9.1 What Hail-Damaged Surfaces Can Be Restored With Green

ENCASEMENT Coatings The restoration case applies to the full range of hail-damaged building surfaces — provided that the structural substrate beneath the damaged surface retains its integrity. Green ENCASEMENT Coating restoration is appropriate when: • •

The roof deck or structural framing is intact — hail impact has damaged the surface system but has not compromised the structural base. The existing surface, though damaged, can provide a stable substrate for coating adhesion — meaning it can be cleaned, repaired of any punctures or major cracks with appropriate patching, and primed. The moisture content of the substrate is within acceptable limits — confirmed with moisture meters before application. Full structural replacement is not required by local building codes due to progressive damage levels.

For asphalt shingles with granule loss — the most common residential hail damage scenario — a Green ENCASEMENT Coating application penetrates the granule surface, fills the microcrack and bruise pattern created by hail impact, bonds to the exposed asphalt mat, and forms a seamless protective membrane that simultaneously restores waterproofing function and provides the elongation-based impact resistance that protects against the next hail event. The granule loss that triggers accelerated UV degradation in conventional shingles is effectively stopped by the coating itself providing UV protection. Hail-Damaged Asphalt Shingles

Green ENCASEMENT Coating penetrates compromised granule surface, fills impact bruising and microcracks, bonds to exposed asphalt mat, restores waterproofing, and adds elongation-based impact resistance. Service life extended 20+ years from date of application.

Hail-Damaged Metal Roofing

Damaged metal surface cleaned and prepared; paint chip and crack damage coated with Green ENCASEMENT Coating that bonds to the metal substrate and provides continuous waterproofing and impact-resilient membrane. Eliminates need for full panel replacement in cases of functional but cosmetically damaged metal roofing.

Hail-Damaged Single-Ply Membranes

Punctures and impact damage points repaired; full-surface Green ENCASEMENT Coating application provides a supplementary protective layer with higher elongation and impact resistance than the original single-ply system, extending service life and protecting against subsequent hail events.

Hail-Damaged Metal Wall Panels

Damaged coating on hail-struck metal siding restored with Green ENCASEMENT Coating application — protecting the substrate from corrosion at exposed impact sites and providing uniform protective membrane across the entire wall surface.

Hail-Damaged Concrete and Masonry Surfaces

Surface cracks from hail impact sealed and waterproofed. Green ENCASEMENT Coating provides penetrating bond that fills hairline fractures and surface imperfections created by impact cycling.

9.2 The Cost Advantage: Restoration vs. Replacement

The financial case for restoration over replacement is direct and compelling — particularly in the context of hail damage where replacement cycles otherwise repeat every 15–25 years for the life of the building. •

Direct cost savings: Green ENCASEMENT Coating restoration typically costs up to 75% less than full removal and replacement — validated on documented Global ENCASEMENT, Inc. projects, with the Portland State University / Fortis Construction project providing independent third-party verification at 1/10th the cost of removal. Replacement cycle elimination: A 20-year guaranteed renewable service life from a restoration application replaces 1–2 full replacement cycles that would otherwise occur

over the same period. The cost of materials, labor, disposal, and disruption from each eliminated replacement cycle compounds the savings. Zero building downtime: Green ENCASEMENT Coating application requires no occupant relocation, no building closure, and no disruption to building operations. For commercial buildings where downtime costs can exceed the repair cost itself, this is a decisive advantage. Insurance deductible management: For buildings with high wind and hail deductibles — Oklahoma averages $6,044 — a Green ENCASEMENT Coating restoration may fall within the deductible range or close to it, potentially allowing the building owner to restore full hail protection without filing a claim and risking premium increases. Embodied carbon preservation: Every roof preserved with restoration is a roof that avoids the double carbon penalty of demolition and new manufacturing. The embodied carbon already invested in the existing roof structure remains in service rather than going to landfill.

10. The Sustainability Case: Why Restoring Roofs Is Climate

Action The connection between hail damage, roof replacement cycles, and climate change operates in both directions: climate change is intensifying hail events, and unnecessary roof replacement is adding to the construction waste and embodied carbon load that drives climate change. Green ENCASEMENT Coating restoration interrupts this cycle at every level. The EPA documents that the US generates approximately 600 million tons of construction and demolition debris annually — one of the largest waste streams in the country. Every roof replaced rather than restored contributes to this total. At the scale of US hail events — where millions of roofs are damaged every season — the cumulative C&D waste from unnecessary replacement is an enormous and preventable environmental cost. The solar reflectivity dimension of Green ENCASEMENT Coatings adds an active climate benefit: the Lawrence Berkeley National Laboratory documents that widespread cool roof deployment could offset 24 gigatons of CO2 globally. Every hail-damaged roof restored with a white or light-colored Green ENCASEMENT Coating becomes a solar-reflective surface that reduces building cooling loads, lowers urban heat island temperatures, and contributes to climate change mitigation — turning a hail damage restoration event into a climate action opportunity.

Up to 75% less costly than full removal and replacement — validated by independent project documentation. [GEI project data] Zero C&D waste generated. Zero demolition. Zero new manufacturing. The embodied carbon in the existing roof is preserved.

20+ year guaranteed renewable service life — eliminating 1–2 full replacement cycles over the same period. Zero building downtime. No occupant relocation. No business interruption. Solar reflective formulations reduce surface temperatures 50–80 degrees F — cutting cooling loads 15–40% and contributing to global CO2 offset. [LBNL] For asbestos-containing roof panels, Green ENCASEMENT Coating restoration simultaneously addresses hail damage AND safely contains the hazardous material in place — avoiding the hazardous waste generation of ACM panel removal. Every restored roof is a roof that avoids contributing to the 600 million tons of annual US C&D waste. [EPA]

11. Verified Field Results: Hail and Storm Protection Across

Five Continents Kadena Air Base, Okinawa — Typhoon and Hail Zone Metal Hangar Roof (110,000 sq ft) A severely deteriorated 110,000 square foot metal hangar roof corroded to complete rustthrough by salt-laden coastal air and repeated typhoon events — including hail impacts. Green ENCASEMENT Coating application delivered a surface that withstood extremely heavy tropical rainfalls without any leaking. Erik M. Olness, Site Engineer, CH2MHill Constructors, documented outstanding satisfaction on record. This project demonstrated seamless encasement performance against both typhoon-force wind-driven rain and hail in one of the world's most demanding coastal storm environments.

Native Health Matters Foundation — Cherokee Nation (20-Year Leak History) A facility roof that had not stopped leaking in 20 years of severe weather events — including hail, ice storms, and extreme temperature cycling — sealed permanently on the first Green ENCASEMENT Coating application. Mary Worsham, Founder & Treasurer, documented the outcome. This verified the restoration of waterproofing function on a roof that conventional maintenance had failed to protect across two decades of hail season exposure.

Portland State University — Fortis Construction (1/10th the Cost of Removal) Green ENCASEMENT Coating encasement at 1/10th the cost of full removal and replacement — independently verified by Jeff Herd, Sr. Superintendent, Fortis Construction, on record. This project demonstrates the definitive cost advantage of restoration over replacement on an institutional building surface.

Sacred Heart Retreat House — Philippines (70,000 sq ft Tropical Storm Zone) A 70,000 square foot lead-paint-containing roof in a tropical storm environment — regular typhoons, heavy rainfall, hail, high humidity, and intense solar exposure. Green ENCASEMENT

Coating application delivered simultaneous hazardous material containment, full waterproofing, and solar-reflective passive cooling. Administrator Agnes Lourdes Monzon documented that the interior became cooler because of the white color reflecting heat from the roof.

Multiple US Military Installations — Storm and Hail Exposure Zones Global ENCASEMENT, Inc. projects at Kadena Air Base (multiple buildings), Yokota Air Base Japan, Washington and Philadelphia Navy Yards, Selfridge Air National Guard Base Michigan, and Yongsan Army Garrison Seoul have all demonstrated Green ENCASEMENT Coating performance in storm and hail exposure environments under US Government GSA contract #GS06F0010J — a 20-year government service contract.

13. Conclusions

Hail is no longer a regional inconvenience confined to the Great Plains. It is a global and accelerating building damage crisis — the single largest category of annual property loss in the United States, a rapidly intensifying risk in Europe and Australia, and a financial pressure on the insurance industry that is reshaping premiums and coverage availability in communities that have never before worried about hailstorms. The science is unambiguous: climate change is increasing the frequency and severity of the most damaging large hailstones, and the buildings that are not protected with the right technology will pay an increasingly high price for that vulnerability. The two-sided case this document makes is equally unambiguous. Before a hail event: Green ENCASEMENT Coatings applied to any building exterior provide high-elongation impact absorption, seamless monolithic waterproofing, and 20+ year guaranteed renewable protection that conventional paint and conventional roofing cannot approach. After a hail event: Green ENCASEMENT Coating restoration of damaged surfaces delivers full waterproofing restoration,

extended service life, and protection against the next event — at up to 75% of the cost of full replacement, with zero building downtime, zero C&D waste, and the added dividend of solarreflective passive cooling on every restored surface. The replacement cycle is not inevitable. The hail damage is not irreversible. And the cost — in money, in carbon, in disruption — of replacing roofs that could have been protected and restored is not a necessity. Green ENCASEMENT Coatings are the answer to both the before and the after. The choice is straightforward. Why replace when you can ENCASE? NOT Paint — ENCASEMENT.
