Interlock® Aluminum Roofing — all-climates performance specs for Clearbrook, Washington
| Spec / Rating | Climate / 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 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy 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 system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet 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+ years | Long-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 transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
I tried for several years to find a roof i would be happy with that would enhance the beauty of my property. When Interlock Roofing came along it was such a relief! I have never driven down a road and exclaimed that is a beautiful roof. Now people tell me I have a beautiful roof! It really is!
This is probably the most professional experience I have had in years. I was blown away. From the time I contacted them, they were on time and did exactly what they said they would do the whole way through. Someone is doing an excellent job of directing this company. I need to contact Paul or Ross because I have more roofs to put on. I would give them a rating of 475! My roof cost twice as much as any other bid, but I am ten times happier than I would have been with any other roof.
They did great on everything.
Interlock Roofing could improve on their communication. We didn't know they were going to start on our project until they pulled up to start the job. We are happy with the product. It took three days for them to do our roof.
Quality control during installation could have been improved. It was expensive.
The only thing that they could have done better is to have brought their sign back. They have not returned the sign.
Weather in Northwestern Washington impacted the schedule by about 1 month, but that’s the weather we get
They could have improved by having better subcontracting and a better process on figuring out who to actually hire for the subcontractors. Patrick and Ivan went above and beyond trying to resolve the issues my wife and I had with the subcontractors.
