Interlock® Aluminum Roofing — all-climates performance specs for South Milwaukee, Wisconsin
| 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:
There was an issue at the end with the cleanup. There was a lot of debris left in the gutters, so my husband had to go in and clean them out. When our 2nd leak issue happened, Jessi saw it and verbalized the gutters should have been cleaned out. Also, I did not like that when the workers came in to get the check we had to fill out a rating scale right in front of them, and I found this a little odd. I didn't feel comfortable having an issue with the cleanup, and making that known in front of them. I didn't want to have to explain why I had this issue to them, so I gave them a perfect score.

Greg was very professional but it just was not in my budget.
We had an Interlock roof put on 4 years ago, and it still looks brand new. We had concerns about hearing the rain on the roof. No problem! We've had two good hailstorms and no dents. We've had so many people just stop by and ask about the roof.

I appreciated the work that they did, they did a very good job.
They were here on time and done in one day, except that they ran out of product.
