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

We needed a small repair on our roof and Ivan came quickly. The repair was done quickly. Ivan explained everything he’d done and answered other questions professionally. Great customer service; we would highly recommend this company. We love our roof!

Review: May 28, 2007Completion: May 5, 2007

I recently had an Interlock roof system installed on my home the last week of April 2007. I am extremely pleased with my new roof. It looks awesome.

★★★★★
Review: January 6, 2018Completion: January 6, 2018

The reason I won't be using Interlock is that at my age and the cost of a new Interlock roof system I can't justify putting on a $30K+ roof when I have other home priorities. If I was 20 years younger and still working I wouldn't hesitate putting an Interlock roof system on.

★★★★★
Review: December 11, 2015Completion: November 24, 2015

I did not like the sales technique. I didn't like how he showed us the pros and cons. I didn't want the huge sales pitch. The visit was long and tedious. Don't let anyone else fall through the cracks either.

Review: December 12, 2017Completion: November 14, 2017

1. A more professional introductory meeting with the start up install that includes either a salesman or representative. This would include a complete overview of the install, ie.. installer introductions, expectations, timeline, general support to the homeowner. 2. FLASHING END CAP NEEDS TO BE DEVELOPED. I'm willing to discuss further with photos if needed. Would appreciate contact from an influential representative.

★★★★☆
Review: October 7, 2017Completion: October 7, 2017

If I win the lottery, I may come back and take another look at the company.

★★★★☆
Review: March 28, 2016Completion: March 28, 2016

I'm glad they came out, I just didn't think it would be that much more expensive.
