Interlock® Aluminum Roofing — all-climates performance specs for Hobart, 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.
Thanks so much for improving the appearance of our home. The difference from before to after is spectacular. It was also nice to have Interlock install gutters as we did not have them before. The job was done quickly (within a week), and the clean up was amazing!! Having had numerous problems with roofers in the past and not having much trust in roofers, It was a pleasure to work with you.
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!
I think Interlock Roofing should provide documentation for the energy efficient federal tax credit. Interlock Roofing does very professional work and happy with their work.
They were great salesman and we appreciate them coming out. We just realized that we did not want to spend that much right now and will wait a while.
There was a delay in getting the skylights, which prevented the completion of the job. The crew could have done a better job of informing me about the delay, and when the job would be completed.
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.
They could come back out and fix the wood trim that they put up incorrectly. I would love for someone to contact me so they can come back out and resolve some issues that I have.
We had ordered an opening skylight, when it came it did not fit. The roofers put in a non opening one and said they would try to find one that fit. To this date we have not heard from them, or the company regarding that skylight. It seems there should be a refund of the difference in the price between the non-opening one and the opening one. I am happy with the roof, I just want either a skylight that opens or a refund of the difference in the price.
