Interlock® Aluminum Roofing — all-climates performance specs for Summit, Illinois
| 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:
Discover why homeowners in Brookfield, IL are choosing Interlock Metal Roofing – Midwest for their Metal Roofing needs: from a smooth, no-pressure sales process to a respectful installation crew, this energy-efficient metal roof has already made a huge difference in cooling costs and comfort.
The Interlock team was a pleasure to work with from beginning to end. Undertaking the re-roof of a 108-year-old home is a major process and investment. After speaking to many other roofers, we realized that Interlock offered the best value proposition, and we felt like they were going to be able to deliver on what they promised.
I am very happy with the results of their work.
It took a really, really long time. It took over five months, but once they finished the roof, they did a good job. Interlock Roofing could improve the scheduling and the communication of when the project would be done. The contractors were awesome.
if our home was newer and we had money to invest into it your product sounded awesome just not right for us at this time
Dear John, I wish I had known about the Interlock Roofing System before I put the last new roof on twenty years ago. If I had, I would not have had to replace it again now.
We signed a contract with John yesterday.
The end of the project. No one told me when the project was going to be finished. The on-site manager told me I had to sign off on the work and give him the check. Previously, I had been told that I would not have to sign anything or submit final payment until I had an opportunity to inspect the finished work. Big difference between what I was told would happen and what actually happened.
None
I think the product will speak for itself. Obviously the cost is higher than the price for asphalt. I thought the crew did a great job and I will recommend to anyone who inquires Communication could have been better. Coordination between my general contractor and an install supervisor would have made things smoother
They could improve by being prepared with their permit before starting the job.
