Metal Roofing in Scholls, Oregon — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—Scholls receives about 1208 mm of rain annually, and Interlock's four-way interlocking aluminum panels are engineered to shed water faster than asphalt. Water runs off the standing seams and ridges without pooling; the overlapping design creates a continuous barrier. When installed to spec over solid decking with underlayment (standard in the Pacific Northwest), the system performs identically to asphalt in wet climates—no leaks. ICC-ES evaluation ESR-1790 confirms compliance with IBC/IRC water-resistance requirements.

Absolutely. Scholls experiences typical gusts up to 120 km/h, and Interlock panels are warranted to withstand wind speeds up to 120 mph—168 km/h. The four-way interlocking design locks panels at all edges, distributing wind load across the entire system rather than stressing individual fasteners. Each panel mechanically engages its neighbors, so gusts that might loosen a single shingle have nowhere to grip. This continuous locking is why the warranty covers 120 mph winds when installed to specification.

Yes—no structural upgrades needed. Interlock's Cedar Shingle profile weighs just 0.41 lb/sq ft, and even the heavier Mediterranean Tile at 0.59 lb/sq ft is approximately 96% lighter than traditional tile or slate. Most Scholls homes built after the 1980s can support this load without modification. Because aluminum is so light, Interlock installs directly over most existing asphalt roofs, eliminating tear-off costs and letting you avoid the landfill cycle immediately. Your framers and engineer will confirm this during the site inspection.

Aluminum literally cannot rust because it contains no iron. Interlock uses roofing-grade 3105-H24 aluminum alloy (ASTM B209), and when exposed to air, it forms a transparent oxide layer that seals the metal and actually self-heals if scratched. Scholls' marine-influenced climate and 37 annual freeze-thaw cycles are exactly where aluminum outperforms steel. The Alunar 70% PVDF fluorocarbon coating—applied to both sides—adds 30-year durability against chalking and fading, protecting the underlying aluminum long past typical asphalt replacement intervals.

Metal roofs handle hail better than asphalt, and Interlock carries the highest available hail rating: UL 2218 Class 4 impact resistance. The warranty even covers perforation from hailstones up to 1.5 inches—far larger than typical Pacific Northwest hail. While Washington County doesn't see frequent severe hail, spring storms can occur. Contact your insurer to ask about premium reductions for Class 4-rated roofs; many carriers offer discounts because metal roofs file fewer claims. The solid aluminum construction simply absorbs impacts that would crack or puncture asphalt shingles.

Yes, particularly in summer. Scholls receives about 3033 hours of sunshine annually, and energy-efficiency-certified Interlock colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they reflect heat that dark asphalt absorbs. Over Scholls' mild 11.2°C average year, this translates to measurably lower cooling-season demand. The Cool Roof Rating Council verification backs this performance. While Scholls is not a hot climate, the reflectivity helps during June–August, and winter heat loss is negligible because the insulation below the roof—not the roof itself—controls that factor.

Interlock offers The Guardian lifetime limited warranty—non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This is the only roof you'll buy for your home. When you sell, the warranty transfers once to the next owner for a full 50 years from completion. No other roofing material matches this combination: the aluminum substrate never corrodes, the 30-year Alunar coating is independently tested, and the transferable term increases your home's resale appeal. That's why Interlock has been manufactured since 1998—longevity sells itself.

Yes. Interlock aluminum is non-combustible, and Class A fire classification is available. This meets Oregon's and Washington County's fire-safety codes and may qualify you for homeowners insurance discounts in areas prone to wildfire exposure. Since aluminum contains no fuel and won't ignite or support combustion, it performs identically whether in coastal salt-air homes (where Interlock installs routinely) or inland. Some insurers explicitly reward non-combustible roofing; request a quote comparison with your current carrier to see potential savings.

Metal requires dramatically less. Asphalt shingles demand moss removal (common in wet Scholls climates), gutter clearing after debris falls, and routine inspections for granule loss or curling—often every 2–3 years. Interlock aluminum sheds moss, never curls, doesn't lose granules, and won't rot. Rain (1208 mm annually) and freeze-thaw cycles (37 days) that age asphalt simply run off smooth aluminum. Most owners inspect gutters once yearly and that's it. The CALGreen verification confirms reduced maintenance burden. This compounds over decades: fewer roof contractor visits and no early emergency repairs save thousands.

Yes—approximately 95% recyclable. Aluminum never loses recyclability; it can be melted and reformed infinitely without degradation. When your Interlock roof eventually reaches end-of-life (a century or more away), the aluminum will return to the recycling stream for new roofing, automotive, or aerospace uses. Asphalt shingles, by contrast, are difficult to recycle and typically landfilled; Scholls residents contribute to this waste cycle with roof replacements every 20 years. By choosing Interlock now, you break that pattern, eliminate the tear-off disposal cost, and ensure the material cycles indefinitely. This aligns with Oregon's sustainability goals and your home's long-term environmental impact.

Yes. Scholls averages about 29 cm of snow, 1208 mm of rain, roughly 37 freeze–thaw days a year, with peak wind gusts near 120 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.
