Interlock® Aluminum Roofing — all-climates performance specs for Arlington Heights, 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: April 22, 2016Completion: April 22, 2016

I am sold on the quality of Interlock products but have read reviews and issues with the installation or craftsmanship in Hawaii and some other places. I am counting on lifetime warranty from Interlock and good customer service from my initial contacts. Before filling out this survey I was thinking about how to coordinate the replacement of skylights. I have the model in mind for four 2 X 4 & one 2 x 2 skylights, and one solar tube. The chimney for the furnace also need to be replaced. I still have some question about flashing or warranty if these parts leak.

Review: September 13, 2017Completion: September 13, 2017

The job site foreman should arrive with the work crew on the first day to go over the details of the project.

Why doesn't Interlock offer a color brochure (competitors do).

★★★★★
Review: June 20, 2017

More financing options should be available with lower interest rates, 9% would be much more attractive than 13%.

★★★★★
Review: June 28, 2017Completion: February 24, 2017

I think they need to have safety equipment and training for the installers. They need more people on a crew and they need to take a good look at the installers before they hire them. I think they need to take a better look at the installers they hire. I wasn't happy that they didn't have the proper safety requirements in place. This left me as the home owner in a very bad place if someone gets hurt on my property. I am happy with the roof now that it is done.

★★★★☆
Review: December 18, 2021Completion: November 8, 2021

I really really want to love my roof, I really do, and I'm almost there, only time will tell for sure. Roofs are an expensive investment literally on your most important asset. You need to have a product you can trust installed correctly to protect you, your assets in the home, and your family. You have choices on what kind of roof to put on and costs all over the place. Interlock aluminum roofing is not cheap, was not the most expensive quote I got, nor the lowest. The things that sold me were material, as aluminum will not rust, and being in Washington state, we get rain often so this was a factor. And then their warranty claims, which sadly I was lied directly to my face by their sales reps. Now don't get me wrong, their warranty is still very good, it was represented to me as even better than it actually is which really pisses me off. Had the sales reps told me the truth, I think I'd still have gone with their product because as I said their warranty is still very good. I hope the product does its job and I never have to use the warranty, that's the real goal here. Better communication, when crew was to arrive, when they would leave, if they leave will they return again that day.

★★★★☆
Review: June 8, 2018Completion: May 30, 2018

Interclock could have improved on time to complete the project. There were about 4 days when the weather was favorable but no worker showed up to do any work. There was no communication from Interlock as for the reason why. The price increase from 46k to 48k was unexpected. We were determined to go with Interlock for a new roof but an opportunity to refinance our home from 5/1 ARM to fixed rate presented itself so took care of that first.Also, it would have been nice to have a final walk-through at the completion of the project before the final payment.
