Interlock® Aluminum Roofing — all-climates performance specs for Sunset Beach, 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:
Overall I didn’t have the greatest experience but that was primarily from the contracted installation crew and their lack of follow through with doing the roof right the first time. Otherwise I’m happy with the way the roof looks and the quality. And despite having to have part of it redone I appreciated the interlock rep going up in my attic and making the crew redo it correctly so I had a quality job. His honesty about the situation went a long way. I would have liked to choose when they were coming. When you’re paying upwards of 50k for a roof I would think you could have some say.
The salesperson was great. They were fantastic.
Correcting the one error quickly. i would like to suggest they look into a better way to do the nailing. The nails are popping through under our roof and it doesn't look very nice. Otherwise we love our 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.
I had a hard time remembering their name. I love my new roof.
See above. Thank you to everyone who helped us throughout this process!
My only suggestion would be to recycle the cardboard packing if possible.
Paul is a great guy. The biggest disappointment is that we couldn't go with Paul.
Over all a good experience, but it's hard to recommend something after such a short time and people's needs are different. See above comments I think it's hard to evaluate a new roof with a lifetime warranty after a very short time and very little rain, but so far we're very happy.
They can improve with a better communication between the installation crew and the client. If there was an Interlock member with the crew as a translator, that could have helped. The installation crew need more tarps and a magnet to pick up the remaining debris of nails. There was asphalt dust all over the yard. I believe it will be a good roof.
