Interlock® Aluminum Roofing — all-climates performance specs for Coveland, Washington
| 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:
Nothing that I can think of! Everyone was great! So far, i am happy with the outcome. I'm sure if I have any concerns or questions in the future, they will be taken care of promptly. Thanks!
None they have done a fantastic job We are extremely happy with our new roof
Exerting more care and accuracy when nailing the plywood down to the existing carport trusses. I was surprised at how quickly the roof came together and to completion. We are both extremely pleased with the new roof. This has been a very bad spring in terms of tree pollen and it settled on the new roof and gave it an orange cast. When the first rain hit about a week ago, it washed the roof completely and the orange cast is gone! :)
The only thing was that we ran out of roofing, so I ended up having to check back with them a couple of days later to find out when they would come back out. The improvement could be just a phone call to let the homeowner know the timeframe it will be in, when things like this happen.
maybe lower the costs that is the one item i had a hard time accepting to begin with even though it is worth it its still a hard pill to swallow.
The installation of our Interlock Roof System was completed this week to our total satisfaction and expectation! The compliments of our new roof are just beginning to be received.
First I would like to say Thank you to your roofers Alex and Aven for a job well done on the installation of my new Interlock aluminum alloy slate roof in Tudor brown. Both men were here each day and worked diligently and conscientiously making sure that each step of their work was done to the highest expectations.
Some preformed material would help with the installation. There was a huge amount of pounding and bending required to install the material.
The company could have improved the communication between the installers and management.
I would do it, but hesitantly. The company, unquestionably. However, due to the problems with the installation crew, not so much so. Train crews all over the nation on doing a daily cleanup, if for nothing more than the safety of the homeowner.Keeping the homeowner advised on the status of their project. I think that I've made enough comments above. If anyone would like further clarification, our number is (360) 679-0820.
If companies are going to take the time to solicit people, then they need to take the time to listen to people. They need to listen to the customers and not just want their money and not care about it.
