Interlock® Aluminum Roofing — all-climates performance specs for Lofall, 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.

Review: June 28, 2017Completion: August 19, 2016

★★★★★
Review: January 7, 2018Completion: December 15, 2017

I felt bad that we only had one guy doing our roof by himself. But he was very professional and has a great work ethic

★★★★★
Review: April 16, 2010Completion: April 21, 2010

Workmanship exceeded our expectations. They had to do a lot of extra unanticipated work and stayed late into the night to complete it. The crew was great!

★★★★★
Review: May 10, 2019Completion: April 12, 2019

I can't really think of anything to improve. I'm pleased with my new roof.

★★★★★
Review: June 21, 2017Completion: June 3, 2016

I found approx 30 nails in my gravel driveway where I normally park and also at the entrance to my shop roll up door after they "cleaned up" and left! I spent many hours with a metal detector and magnet trying to get them all up so I didn't get a flat tire! Ross said he was going to have them come back with their magnet to scour the area but I never seen them. Some of the nails were the ones they used installing the new roofing so they are Aluminum and a magnet won't pick them up. It would have been so easy for them to have put down a cheap tarp under the trailer they used to haul off scrap material....I spent $55k on a roof and did not expect to have to clean up too....As to the workmanship, had to have Ross come look at a valley that was messed up and very visible, he did have them come back and do it correctly. The prospects I showed the roof to mentioned it to me also which probably didn't help in the decision...I did show them again after it was fixed but that was not the point, should be done right for that much money the first time.

★★★★★
Review: February 8, 2022Completion: December 22, 2021

Overall, the team that came out to do the work did a pretty good job, worked very hard, and finished the job in a timely manner. They could have improved in cleaning at the end of the day to make sure materials aren't thrown all over the place. They tried because there was one individual that went around. Sometimes they missed, but it's not really a big deal. They did a good job installing the roof, and it looks nice.

★★★★★
Review: November 21, 2017

I appreciate Ross also.

★★★★☆
Review: April 10, 2018Completion: March 27, 2018

I would with hesitation. There was a huge communication issues and it had to be addressed. The workmanship fell short and I would have expected, the workmanship to did done.

★★★★☆
Review: February 1, 2020Completion: November 20, 2019

Just a concern with high cost. Better final clean for nails.Not put up advertising sign."Post" photo taken when said.Less gravel driveway damage, stay on road, not grass. We like the look and function of our new slate-look metal roof.
