Interlock® Aluminum Roofing — all-climates performance specs for Penhold, Alberta

Spec / Rating	Climate / 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 4	Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profile	Heavy 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 system	High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surface	Wet 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+ years	Long-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 transferable	Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

What our customers are saying:

★★★★☆

Review: August 8, 2016Completion: June 30, 2016

I am hesitant to recommend them until the problem is resolved. Other than the eave trough issue, everything was fine. If I would have known it was going to cover them I would have asked them to take them off. I hope they come out and cut the hangers off of my eave troughs.

Joan S.Penhold, AB

★★★★☆

Review: October 1, 2014Completion: July 22, 2014

A little more heads up of when the installers would be coming. We received a phone call the night before they arrived and would have appreciated a little more heads up.
