Interlock® Aluminum Roofing — all-climates performance specs for Chatham, Illinois

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: January 25, 2016Completion: December 30, 2016

Dear Mark, I would like to provide you some feedback on the first phase of work done on our project at the Church of the Nazarene, in Chicago Heights. Before going into the details of the work performed, I would like you to know how pleased I was putting together this project with your sale manager, John Mondschean. Thank you for a job well done. This job was well-managed and professionally carried out. I look forward to the second phase of our project in the fall.

Review: June 7, 2004Completion: June 30, 2004

Now that our new Interlock Roofing system has been installed, we find the look to be extraordinary! It boasts sophistication and looks clean and elegant. Almost more important than the attractive look of our new roof is the peace of mind we have gained with its many features.

I can not think of anything they could have improved on.

★★★★★
Review: August 12, 2017Completion: July 29, 2017

I wish that the aluminum was a little bit thicker. It would give the appearance that it would hold up longer. I wish that they would call me every 5 years for the next 50 years. I am expecting a call every five years for the next 50 years. Only time will tell how well the product is holding up.
