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

Yes. Interlock offers five authentic profiles—Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—each cast from roofing-grade aluminum. The Tile profile weighs about 96% less than concrete or clay tile, so your home needs no structural reinforcement. All profiles use four-way interlocking aluminum panels with Alunar 70% PVDF coating on both sides, warranted 30 years against fading. You get the architectural look you want without engineering costs.

Metal roofing is the last roof you'll likely buy. Asphalt typically lasts 15–20 years; Interlock carries a lifetime limited material warranty for the original owner, plus 50 years of coverage if you transfer it to the next owner—eliminating the tear-off-and-replace cycle every two decades. Lebanon's 1166 mm annual rainfall and 37 freeze-thaw days annually accelerate asphalt degradation. Current financing offers no payments or interest until Spring 2027, or 10% off installation, making the entry cost competitive.

Aluminum cannot rust because it contains no iron—the element that oxidizes in water. Instead, a thin, transparent oxide layer forms on aluminum's surface and automatically heals when scratched, providing permanent corrosion protection. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy per ASTM B209, with Alunar 70% PVDF fluorocarbon coating applied to both sides for extra salt-air and moisture resistance. Lebanon's 1166 mm annual rainfall makes this self-healing oxide layer a genuine advantage over steel.

Interlock aluminum achieves Class A fire rating because aluminum itself is non-combustible; it cannot ignite or spread flame. The material is ICC-ES evaluated under ESR-1790 (current 2025 reissue), meeting all IBC/IRC codes. Check with your insurer—some offer discounts on non-combustible roofing, offsetting part of the installation cost. In fire-prone regions of Oregon, this rating increasingly influences underwriting decisions and can improve your policy terms.

Virtually none beyond annual gutter cleaning. Unlike asphalt (which cracks and curls in Lebanon's 37 annual freeze-thaw cycles), wood shakes (which rot and split), or concrete tile (which requires resealing), aluminum panels don't degrade from weather cycles. The Alunar 70% PVDF coating is CALGreen-verified for reduced maintenance and warranted 30 years against chalking and fading. You gain back time and money—no algae treatments, no re-caulking, no seasonal inspections.

Metal roofing is a recognized upgrade that signals durability and modern energy efficiency to buyers. The architectural profiles—Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam—appeal across style preferences, and the transferable 50-year Guardian Warranty adds genuine value because the next owner inherits a roof that will outlast their ownership. Visible quality and long-term protection are strong selling points, especially in a region where 1166 mm of rain per year makes roof durability a practical concern.

Interlock metal installs directly over most existing roofs because aluminum is extraordinarily light—the Slate profile at 0.41 lb/sq ft and Tile at 0.59 lb/sq ft add minimal structural load. Tearoff cost and labor are eliminated, speeding installation and reducing waste. The lightweight design means your existing framing, built in an era when asphalt was standard, easily supports the retrofit. Installation typically takes days, not weeks, with minimal disruption to your home.

Aluminum is approximately 95% recyclable and retains full value through unlimited cycles—unlike asphalt, which becomes landfill waste after 15–20 years. When you eventually replace the roof (decades from now), Interlock panels return to aluminum mills and become new product: no manufacturing waste, no toxins in the soil. This breaks the asphalt tear-off cycle that has filled Oregon landfills for decades. Choosing metal means your roof material has a second life.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Lebanon's typical peak gusts are 105 km/h (about 65 mph), with recorded extremes lower than the warranty threshold. The interlocking design distributes force across adjacent panels, preventing uplift even in sustained wind. Your roof's warranty covers you well beyond typical regional storm intensity, providing security that loose asphalt shingles simply cannot match.

Lebanon receives about 1166 mm of rain annually; Interlock's four-way interlocking aluminum panels shed water like a single continuous surface, with overlaps that direct flow downward and outward. The design eliminates the gaps and seams where asphalt shingles allow leaks after nail holes enlarge from freeze-thaw cycles. Each profile (Slate, Cedar Shingle, Shake, Tile, Standing Seam) channels water efficiently. Proper underlayment and installation per ESR-1790 create a dual-barrier system, so the roof underneath stays dry for decades.
