Interlock® Aluminum Roofing — all-climates performance specs for Lake Morton-Berrydale, 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:
We have already recommended them. We put Ross in touch with our contractor for our contractor's other clients. We really had a great experience and everything went smoothly. The coordination of the project went really well and it was very smooth.
Have done! Most of the people I recommend Interlock to are greatly concerned about the cost; but our house was small and easy so the cost to us was not beyond what we wanted to pay for such a high quality roof. When we originally contacted interlock we needed a metal detached garage roof replaced. I explained the roof and the type of building and its construction to the person on the phone who said they could replace the roof. When the sales representative came to our property they were not able to replace the roof on our garage. But we knew we needed a new house roof and decided to go ahead with that. I wish your survey had a way to attach a photo, the house looks great!
Interlock Roofing-Seattle provided professional service and the people are easy to work with. If there are any issues on your side, they'll take care of it, and also answer your questions. It is a little difficult to interface with the Ukrainian workers, but it worked out using a translation app to communicate. They'll get better as they go, so it's not an issue; everybody needs to work! They have great workers and there were no problems. For composition type roofing, they do need a better magnet to pick up the nails. They could have improved the communication and clean-up pertaining to picking up nails. It was a great experience! They have great crews!
Such great service. We have had our roof for 5 years. Looks beautiful still
It went very well, were thrilled. I just love it.
I am pleased with product and the overall service.
Kim was tired of breaking tiles every time he had to clean his roof. He was sick of finding leaks on rainy, windy nights. He did his research, talked to different companies, and decided Interlock® was the way to go for him and his girlfriend.
They did great. Just because I am not going to use the company doesn't mean that I wasn't impressed with the company and presentation.
I would say that the price is the only thing, even my rich friends are worried about the cost. I would say the price is the only thing. I got it becasue I wanted it not because it was cheap. Thanks for the efficient installation and the skylight is very impressive.
None
I would like to go with them, but I haven't yet because of different things I found on the internet regarding the warranty and how other people's reviews state that the roofs leak and the company doesn't follow through with replacing the roof.
Scheduling updates for the project before I ask for them would be good. This job got pushed out 3 times with only 1 day notice. Scheduling to be here is very difficult with this short notice. It would be nice if the Forman of the installation crew would talk to me when they show up and also when they are leaving each day. I am also awaiting a refund for services not needed but included in my original quote.
