Interlock® Aluminum Roofing — all-climates performance specs for Delafield, 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:
I want to share my experience about getting a new roof with Interlock Roofing. I purchased a house with the knowledge that a new roof was needed. The idea of an expensive reoccurring expense on anywhere from a 15 to a 25-year time period was unsettling. After purchasing my townhouse, one of my goals was to make my house as maintenance-free as possible with the knowledge that in the future, the home may not be owner-occupied. After I had Greg Webber come out and give me an estimate, I took a bit of time to do research and look at quite a few homes with different styles and colors. As an engineer, I was impressed with the material and the commitment that Interlock has to stand by not only the product but also the installation. The thought of my roof either maintaining or appreciating in value over time put my mind at ease, looking forward to the future. After deciding to move forward with Interlock, the decision was what color and style. This was maybe the most difficult part of the decision, and am thankful for Greg, and the patience had with me. I was able to find a time that would be feasible for Greg and another family member to finalize the color and style. I went with the slate and the weathered gray which ended up matching well with the front of the house, which has white and gray in the brick and did not contrast to sharp with the tan of the siding. Due to the original construction of my house, there were some concerns that I had with the roof and the install. When the house was originally constructed, there was only roof vents on one side for ventilation; also, I wanted to remove the Satellite dish that was installed on the chimney and last but not least, the flashing around the chimney was incorrect and did not have a kick out to drain the water into the gutters, and therefore I drained into my garage instead. Jesse did a terrific job of the installation and addressed all of the issues of the original construction, and couldn't be any happier. Since completion, I have received numerous compliments from neighbors and friends. If I had to install a roof again, there would be no question that I would go with Interlock Roofing again.
