Interlock® Aluminum Roofing — all-climates performance specs for Medina, 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:
Interlock Metal Roofing is a wonderful product. Michael did an awesome presentation and was very professional and thorough answering all of our questions. If you are in the market for a new roof give them a chance!
Deciding to switch to an aluminum roof was a significant decision for us, and honestly, the selection process was a bit overwhelming. There are so many styles and finishes available, and it took us quite a while to finally make our choice. If you're considering aluminum, be prepared to invest time in understanding your options. The installation process itself also took longer than we initially anticipated, especially compared to the asphalt shingle replacements we've had done in the past. However, despite the longer decision and installation periods, we are extremely pleased with the final result. The aluminum roof looks fantastic and has significantly improved the curb appeal of our home.
Great work on time excellent communication excellent clean up
We were extremely satisfied with the result of the installation of the roof. The process was smooth, and the quality of the product is very good. The communication after the signing of the contract could be better. I was extremely happy with the installation, and the product is supreme.
The crew did a good job and they try to get it done before sun going down and so they work very hard and fast. But by doing that the details of the work is when out the windows , the quality of the work is not there . Taking another day to get it done would please any owner with the work done right and nothing left for the owner to pick it up later. Thanks for the hard work and got it done in one day.But quality of the work is not there so if in the future please! Take your time to slow down and look over your work it would be more professional way to provide a service. I hope you can use the recommendation from an retired airplane builder and testing.The products are the best plus the quality of your work makes it hard to beat by any competitors out there on the market thanks again
We are extremely happy with our new Interlock standing seam roof. The appearance is great, the heat absorbtion is noticeably lower than our old asphaltic shigle roof, and we won't have to worry about our roof for another 50 years! Better communication about the delays.
To a person everybody in sales (Ross specifically) at Interlock Roofing was knowledgeable and professional. When we were evaluating our roofing alternatives, they took the time and energy to answer our many questions. Obviously, there are less expensive alternatives, and they did a good job explaining the differences.
It’s such a relief to have a beautiful, reliable roof over our house now. Patrick, Tony, and the installation crew had their work cut out for them with our 1911 Craftsman’s steep roofs.
Mr. Ross and Interlock Industries, Kathy and I are very pleased with our new roof. During installation, your crew was able to adapt the project around our 100-year-old chimneys and finally completely seal us against leaks. The first summer of the new roof was worth the project’s price and exceeded our expectations for performance.
Overall a great experience and product - no concerns or recommendations.
They could have improved on the scheduling. Overall I am happy with the roof, it look greats.
I want to express my appreciation for your company's excellent response to our recent need for replacement of deteriorating closure material on our metal roof installed about four years ago. It is a pleasure to deal with people whose first priority is customer satisfaction.
