Interlock® Aluminum Roofing — all-climates performance specs for Larch Mountain, Oregon
| 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:
Communication was sorely lacking. I had to call to find out when and if they were coming. We were told that they would be delivering materials a few days prior to installation( only when I called, did I find out that they would be bringing materials with them), but and also told that I would receive a confirmation call(which never came- then when I called l was told that the install date had changed). I understand that a staff member was ill, but there should be a backup person to handle these things. The appearance of our house has improved vastly, the shake roofing is beautiful. We have had many compliments from passersby, and to be honest, we have the most beautiful roof in the neighborhood. We love it so much, that any home that we may purchase in the future will definitely receive an Interlock roof.
Your roof and Michael both seem amazing. I can't think of anything about either that I didn't like. Well, other than the price. I understand a good product is going to cost more. Honestly we just can't afford it right now.
Great product. I would be happy to promote when our roof gets done.
Prompt, ongoing communication from bid to follow up after completion. Install crew was professional and polite. We had an involved tear-off and they spread tarps overnight in case of dew. Finished job looks great.
Nothing, everything was perfect. The team from start to finish was A+.
Ivan and I have had many visits over the last 10 years we have had our Interlock roof. He is a rare find. Both knowledgeable and conscientious.
They could have done a little better with picking up all the nails after the tear down. We found some nails in our driveway.
Living in the Pacific NW, we have a lot of rain and my old roof decided it was done. I checked into many types of new roofs and found this to be the best on the market.
When I was younger, I installed some roofs, including (25 years ago) the one that was replaced. So I know how hard that work is.
We are likely to use your product when we move in the near future.
Everything went extremely well. Mike Rasmussen did everything very well.
The communication between salesman and the installers. We agreed that the installers would run the TV cable along the side of the house under the awning but it is still laying on the roof. I will contact comcast to try and get this addressed. I am also unsure if the vent for the roof got taken care of. There is a dryer/restroom vent on the roof that was stuck shut and trapping humidity in the attic under the roof. I am going to try and see if I can go up and check this myself. Ivan noticed the condensation residue from the vent holes on the side of the house. He said that would also be taken care of.
