Interlock® Aluminum Roofing — all-climates performance specs for Hope Island, 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:
We were extremely pleased with Interlock Roofing as our selection to install an aluminum roof on our house and two outbuildings. The installation team were extremely hard workers and were always courteous and conscientious and left our project very clean. We would highly recommend all of them to anyone interested in a new roof including Paul Wright and the administration staff. Ron and Joanne Quiring nothing
Our house was built 26 years ago beautiful rambler but on the Golf course. The original roof was black cement tiles and 6 years later without any protection from the golf balls we had to change to wood shakes. That roof lasted 20 years with lots of problems like leaks and ants invasion. It did not matter if we had a protective net from the golf balls and it was time to do something. I found Interlock on the Internet and when I checked with our community covenants they did not have anything against metal roofing. I choose the Red slate and I am so very happy with my choice. Now I will never again have ants or leaks because I was watching how the crew sealed everything and the job was done very professionaly.Thank you Interlock for making my home look so beautiful they could have had the delivery of the tiles during the preparation and removal of the shakes; the Federal Express was one week late and the roof sat there all ready for the delivery. I don't know whose fault it was but then the crew worked diligently to finish the job. I am very happy with my new roof the first in the area where I live and everybody is taking about it.
all good
In March of 2016, we contracted with Interlock Lifetime Roofing Systems to replace the cedar shingles on our roof. After a couple of dates were scheduled and changed, the job was finally completed on June 22, 2016. The work crew was very good – showed up as scheduled and the work was completed in 2 days.
The adjusted bid didn't show up for final financing, there could have had better communication between Ross and everybody else, Ross and I discussed at length and the gutters didn't end up on the installers paperwork.
Need someone on the crew that speaks better English for improved communication.
