Interlock® Aluminum Roofing — all-climates performance specs for Lakeland North, 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: July 8, 2017Completion: November 21, 2016

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!

★★★★★
Review: April 16, 2025Completion: March 29, 2010

I've had 2 Interlock Metal Roofs and 2 different houses. One in 2003 and the roof still looks great - almost like new after 22 years! The other, after we sold & moved to a new house in 2009 we went with Interlock again. The durability, warranty, and the good looks of the Interlock is why we paid the extra cost. I highly recommend Interlock. Stellar installation service, great attention to detail, clear explanations, and careful aftercare. You can certainly find a cheaper roof, but you can't beat the quality and longevity.

Review: August 22, 2018Completion: August 22, 2018

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.

★★★★★
Review: June 12, 2019Completion: June 12, 2019

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.

★★★★★
Review: February 20, 2019Completion: February 2, 2019

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.

★★★★★
Review: April 12, 2000Completion: April 12, 2000

In less than a week since the new Interlock roof was installed on our house we have had several compliments. It is somewhat a coincidence that the color of paint we put on the gutters and gable ends a couple of years ago is compatible with the weathered copper color of the shingles. Most homes in our neighborhood are between twenty and thirty years of age. All have been re-roofed. Some need replacement again. They should consider Interlock. The weather was not always the best during the job. The installers seemed to know exactly what to do and how to do it. If the roof is as good as it appears and is warranted for, the cost is justified. In comparison with anything else around we're quite proud of it.

★★★★☆
Review: October 13, 2015Completion: October 13, 2015

I was impressed with Ross Peterson's presentation of the information to us. He was very very friendly in a non-pushy way. It really is a situation so many times with salespeople where they are so eager to get a deal they start getting pushy and show frustration when you don't buy at that moment. That was not the case with Ross. He also knew we weren't in the market for another year or two. Hopefully it will all work out.

★★★★☆
Review: July 30, 2018Completion: July 30, 2018

English has a second language workers when calling and leaving messages need to speak slower so they can be understood.
