Interlock® Aluminum Roofing — all-climates performance specs for Techny, 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: September 13, 2023Completion: July 31, 2023

If you want the best quality shingles that are secured on all 4 sides, contact Interlock. You could let me know when you would pick up the yard sign, or if I should toss it after a couple of weeks. I'm still waiting to hear from my insurance (State Farm) if I get a discount for having a much higher quality roof on the house.

★★★★★
Review: June 8, 2023Completion: April 24, 2023

It's beautiful, and I don't think there's anything more they could do. We have another final project coming and have allowed for the extra materials.

Review: October 1, 2014Completion: July 25, 2014

#1 I still have no sign in my yard, after copious rain destroyed the original one. Chuck was made aware of this at least 1 month ago. #2 Since part of his pitch that landed the sale included any referrals from the sign promised, and NONE have emerged...kind of hard to follow through on an invisible sign. #3 Roofers told me that Chuck had not included a complete rip-off job on my roof, but they did it anyway. #4 Took over 1 month for my check to clear. #5 In request of an invoice noting paid in full, Chuck told me that it was in the snail mail in August. Said invoice never arrived. Finally after multiple calls, he sent me an email invoice.

Review: March 28, 2017Completion: March 28, 2017

Dear Mr. Mondschean It has been slightly more than one week since the installation was completed, and I thought I would offer the following: Noise — Since completion, we have had two rainstorms, a four-inch snowfall, and a minute heavy hailstorm. The only annoying noise experienced was during the hailstorm.
