Interlock® Aluminum Roofing — all-climates performance specs for Naco, Washington

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

Review: May 23, 2019Completion: April 30, 2019

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.

Review: January 16, 2024Completion: December 20, 2023

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!

Review: March 8, 2018Completion: March 8, 2018

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.

Review: February 28, 2015

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.

Completion: December 9, 2015

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.
