Interlock® Aluminum Roofing — all-climates performance specs for West End, Washington

Spec / RatingClimate / Risk Factor + What It Solves
Wind resistance: 120+ mph (193+ kph)Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events.
Fire rating: Class A (with proper assembly)Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating.
Hail resistance: UL 2218 Class 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.)
Corrosion resistance: aluminum (won’t rust)Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments.
Heat / UV durability: baked-on coating systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance.
Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam)All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather.
Expected lifespan: 50+ yearsLong-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments.
Warranty: Lifetime-Limited, non-prorated + 50-year transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

Review: February 17, 2019Completion: February 6, 2019

I didn't get as many updates about scheduling as I would have liked. I had to call several times to get projected dates over the course of several months. We are very happy with the finished roof. The crew did a very neat and professional job, with careful attention to detail. We love the color.

Review: May 8, 2019Completion: May 8, 2019

I had full length venting at the peak of my roof, not the typical multiple roof vents scattered about. After install I asked if the top cap put on was adequate for the same type venting that it replaced. A man called and explained it was vented at the peak and I would be able to see this from inside the attic, which is not easy to access on my roof. Anyway, I'll trust your company that my roof is properly vented per building codes, but you might consider some type of "show and tell" to other customers with peak vented roofs like mine to assure them "visually" that the Interlock peak shingles do in fact vent adequately/per code requirements. -Rocky Cowart We've had several slow vehicle drive bys of people looking at our new roof. I'd be very surprised if you haven't received calls from some of them as your "high vis" advertisement sign is also hard to miss.... :-)

Review: March 12, 2019Completion: March 2, 2019

Since weather was an issue, it would have been nice if the office staff would have called instead of emailed when there were changes. The only frustration my husband and I had was not knowing who to contact for our job. In the emails sent to the customers it should include the project formans name, and contact number. Also, it should include a start time or encourage the owner to call the project Forman to clarify a start time. I am so happy that we made the choice to install an interlock roof, thank you for the best product we could invest in.
