Interlock® Aluminum Roofing — all-climates performance specs for Gales Addition, 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:
I am seemingly pleased with the product and the crew was great. They might be able to improve because, during the installation, they had another project so they were going back and forth between the 2 projects. Some days there was a full crew and some days they were only a couple of guys. They did a great job with the schedule they had but they didn't seem like they had the liberty to focus on one job at a time.
Thorough estimate of the project. Tripe check t measurements for accuracy. At the last minute additional costs incurred due to the inaccurate measurements taken at the time of the appointment.
None.
Lack of communication from Interlock to homeowner and installation crew about delay in materials delivery. At the end of the first day of tear off, we did not know who or when a crew would be back to finish the work, until we as home owner started making phones calls !!
They should let the homeowner know the crew's arrival time. I just remember looking out the window at 6 a.m. with his arms crossed, staring at what looked to be mean, but he was looking at the roof, and my blood ran cold because this was a different person who showed up from the previous day. My husband went outside, and we were relieved it was the installation crew, but it would be nice if they would let us know that information prior. We thought it would be loud when it rained after the project was completed, but that's definitely not the case; it's more quiet than insulated, and we have no leaks!
If I had not been there to immediately identify problems, which were a result of the language barrier with crew on site not understanding the particular specifications of the job, it could have turned into a real disaster. Such things as not putting ventilation sheathing on the vaulted ceiling portion of the roof; then trying to put it not only on the vaulted ceiling, but other parts of the roof, where it was not required.
