Interlock® Aluminum Roofing — all-climates performance specs for King City, Oregon

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 24, 2024Completion: July 22, 2024

We were so impressed with Interlock Roofing. The entire process was great from sales, to installation to clean up. They made the process easy even when we had a few curveballs for them. They worked with us wonderfully the entire time and our roof looks amazing. The installation team was so nice and respectful. Our roof is beautiful.

Review: September 15, 2019Completion: December 6, 2016

Interlock Roofing did a very good job of installing our roof. I was worried that it would be a little too hard to do this in the middle of winter, but they did a great job. I would recommend this company to anyone contemplating a metal roof for their home. The only negative comment I have is the clean-up could have been a bit better. I covered my gutters after the roof was installed, and found a lot of debris in the gutters as well as on the ground. The debris were mostly pieces of cut metal tiles with very sharp edges. In fact I found this debris on the ground for several months after the job was completed. I suspect that the installation crew was cold and tired and may not have taken as much time as they normally would have because of the weather. Our expectations of this medium ( metal) was fully confirmed and we couldn't be happier with our choice. Thank you Ralf C.

Review: April 25, 2025Completion: April 10, 2025

Interlock was a great process, their sales team was very helpful and knowledgeable, the install team had the old roofing removed and the new one installed in a few days. We chose the black "slate" panels and it looks awesome and it doesn't sound much different in the rain than our old asphalt shingles. A bit of an investment but I'm glad we went with interlock.

Review: July 12, 2017Completion: June 22, 2017

I think it would be nice if they could build a cover or a dome that would be just above the sky lights. I live under trees and I get a lot of debris and then all the debris piles up on the skylights and floods water into the house. If they could build some sort of cover that could prevent buildup I think it would be helpful. Also, at the end of the ridge caps it would be nice to have a ridge cap plate that is cut in a pointed shape because they had to cut/bend it to shape by hand. It didn't look quite as professional but it was satisfactory. My neighbor did complain when the crew took flashing and leaned it against his newly painted gutters. I think they could've placed it somewhere else. Mike was very knowledgable and I learned a lot when he talked about warranty and how they are used. His sales pitch was very informative. I am quite happy.

Review: August 15, 2019Completion: October 13, 2017

We live in Tigard Oregon. We were able to schedule the installation of the new roof just before the Rainy season began. We had the old shingles removed and found that our plywood was rotting.

Review: April 7, 2015Completion: March 16, 2015

We still have not received our sky lights. I have no idea when they are coming. Some more communication on that would be nice.

★★★★☆
Review: June 23, 2021Completion: May 11, 2021

It's expensive, but other than that - a great roof. Interlock Roofing could have improved on their communication between salesman and installers.
