Metal Roofing in Hays, Pennsylvania — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—aluminum's non-porous structure makes it immune to the damage that freezes and thaws inflict on asphalt and wood. Hays experiences about 75 freeze-thaw days per year, which causes asphalt shingles to crack, curl, and lose granules. Aluminum expands and contracts uniformly without absorbing moisture, so it never splits or delamrinates. The Alunar fluorocarbon coating protects both sides of the panel (even the underside exposed to condensation), and the material's self-healing oxide layer resists corrosion from salt and road spray. Over a 30-year lifespan, this resilience eliminates the repeated roof repairs that freeze-thaw climates demand.

The smooth, slippery aluminum surface sheds snow and ice more readily than rough asphalt, reducing ice-dam formation and the weight load on your home. Hays averages about 58 cm of snow annually, which accumulates quickly on steep pitches. The four-way interlocking panels lock together to prevent water infiltration even if ice dams do form, and the lightweight design (the Shingle profile weighs just 0.41 lb/sq ft) means snow load stress is far lower than with traditional slate or tile. Optional snow guards can be installed if you want to control sliding on steep roofs—a choice unavailable with heavier materials that already strain framing. The system is code-compliant under ICC-ES ESR-1790 for snow-load ratings.

No—the four-way interlocking panel design creates a locked seal that sheds water faster than asphalt, even in Hays's 1,203 mm of annual rainfall. Each panel overlaps and locks into its neighbors on all four edges, and when installed over solid decking with underlayment (standard practice), the system is indistinguishable from asphalt roofing in rain performance. The interlocks physically prevent water from being driven upward under wind-driven rain conditions. Metal reflects rain away rather than absorbing it like asphalt does, so moisture never saturates the roof substrate. Because aluminum cannot rot or delaminate, even if water somehow breached the interlocks (extremely rare with proper installation), the substrate remains unharmed—unlike asphalt or wood shingles.

Aluminum roofing cannot rust because rust requires iron, and roofing-grade 3105-H24 aluminum alloy (ASTM B209) contains zero iron. Instead, aluminum naturally forms an invisible, self-healing oxide layer that blocks corrosion. When the coating scratches, this oxide reforms automatically—a mechanism that continues throughout the roof's life. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel for extra protection in moisture-rich environments. Hays receives steady rainfall (1,203 mm per year) and freeze-thaw cycling that accelerates rust in steel roofing, but aluminum thrives under those exact conditions. The Guardian Warranty explicitly covers rusting (a claim no steel roof manufacturer can make), backed by 25 years of installations from coastal salt-air zones to Antarctic research stations.

Interlock aluminum roofs carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Class 4 is rare for roofing and often qualifies homeowners for insurance premium discounts because the roof outlasts the insurable risk. Pennsylvania experiences significant hail in spring and summer, and many insurers recognize that metal roofs in this category dramatically reduce claims. The lightweight aluminum (the Tile profile is 96% lighter than concrete or clay tile) distributes impact energy differently than brittle materials, and the interlocking design means a localized dent doesn't compromise the whole roof. Your insurance agent can confirm available discounts when you request a quote—many carriers now actively encourage Class 4 metal roofing.

The four-way interlocking system warrants wind resistance up to 120 mph (193 km/h), far exceeding Hays's typical gusts of about 92 km/h. Each panel locks into its neighbors on all four sides, creating a unified assembly that resists uplift and lateral stress. The design means individual panels cannot be separated by wind—they move as one. Hays's annual average wind speed is about 16 km/h, but spring storms occasionally produce strong gusts that can lift or curl asphalt shingles. The interlocking aluminum system remains fixed because the locks prevent the peeling mechanism that destabilizes asphalt. The ICC-ES ESR-1790 evaluation report (reissued 2025) confirms compliance with wind-load provisions in the International Building Code for residential roofing, giving you confidence that the system meets Pennsylvania's structural standards.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also transferable once—the next owner receives 50 years of coverage from completion. Few roofing materials come with non-prorated lifetime protection because most degrade predictably over time; aluminum and the Alunar 70% PVDF coating resist that degradation. Real-world installations since 1998 show roofs functioning flawlessly after 25 years in diverse climates. The 30-year coating warranty (ASTM D4214/D2244) confirms resistance to chalking and fading under Hays's 2,978 annual sunshine hours. When you factor in zero maintenance costs and no tear-off required, an Interlock roof becomes the last roof you'll buy.

No structural reinforcement is required because Interlock aluminum roofing is extraordinarily light. The Shingle profile installs at just 0.41 lb/sq ft, and the Tile profile (which visually replicates traditional tile) weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. By comparison, slate weighs 7–15 lb/sq ft, so homeowners upgrading from asphalt (about 2–3 lb/sq ft) experience negligible increase in roof load. Because the material is so light, it installs directly over most existing asphalt roofs without removing the old layer, saving money and landfill waste. The low weight also reduces stress on framing during wind events and snow accumulation (Hays averages 58 cm of snow annually), extending your home's structural lifespan. ICC-ES ESR-1790 confirms the system's safety for standard residential framing.

Interlock aluminum roofing requires virtually no maintenance—no seasonal inspections, no resealing, no granule replacement. Asphalt shingles demand regular upkeep: granules wash away in Hays's 1,203 mm of annual rainfall, fasteners loosen in freeze-thaw cycles (about 75 per year here), and UV exposure requires tar-patching every few years. Wood shingles rot, curl, and harbor mold in humid climates. Aluminum doesn't absorb moisture, so it never needs caulking, coating refreshers, or fungicide treatments. The CALGreen-verified design eliminates maintenance-cycle costs. Over a 30-year span, this absence of upkeep—combined with zero rust, rot, or cracking—transforms a roof from a liability into a set-and-forget asset. Most owners simply rinse gutters and let the material perform. The Guardian Warranty covers defects but not wear items, because wear is vanishingly rare.

Yes—aluminum roofing breaks the asphalt tear-off-to-landfill cycle and is approximately 95% recyclable at end of life. When you replace an asphalt roof, old shingles are typically torn off and sent to landfills where they persist for decades. An Interlock roof often installs directly over existing asphalt (because it's so light), eliminating that waste stream immediately. The aluminum itself never degrades into granules or fibers; it simply ages gracefully under the Alunar 70% PVDF coating. When your roof eventually reaches end-of-life—a 50+ year horizon—the entire assembly can be recycled into new aluminum products, closing the loop. The lightweight design also reduces transportation emissions compared to heavy tile or slate. CALGreen verification confirms the system's reduced maintenance footprint. Choosing aluminum means your roofing investment doesn't mortgage the next generation's landfill capacity.

Yes. Hays averages about 58 cm of snow, 1203 mm of rain, roughly 75 freeze–thaw days a year, with peak wind gusts near 92 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
