Interlock® Aluminum Roofing — all-climates performance specs for Dunbar, British Columbia
| 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:
Fantastic service, clear & consistent communication, and a beautiful, durable product. Simply one of the best contractors we have ever worked with. We got quotes from numerous leading roofers for this job. Mike from Interlock was the only one who came to our house, spent an evening patiently explaining every aspect of the job, showed us many photos and described some of the technical aspects in ways that were easy to understand. When we called back with more questions, he was always available and always super helpful. For the installation, Mike recognized that we had an old house and were concerned about the workmanship. He sent us an experienced crew led by Oswaldo that went above and beyond any expectation we could have had. They not only protected our home but also took pains to protect the neighbors' homes beside ours. They gave us near daily briefings and showed us photos of everything they found on our roof and their work throughout. The job ended up taking much longer than anticipated because our roof had many problems that needed to be repaired. Oswaldo and Mike worked with us to make sure everything was taken care of and repaired before the new roofing was put on. They proved flexible and extremely diligent, communicating effectively throughout. We are thrilled with the result and grateful for all their hard work. We would not hesitate to use their services again and highly recommend them to anyone looking for roofers. As a bonus, we're delighted that we will never send another huge pile of asphalt shingles to the landfill again!
We have recently had an Interlock Lifetime Roofing System installed on our house. The initial questions and concerns we had were answered by Colin to our full satisfaction. Upon doing our due diligence prior to agreeing to the job we found that both the price and quality of the Interlock product were unmatched in the marketplace. The job was done in a timely and professional manner in all ways. We are very happy with the results.
I found the sales staff to be very knowledgeable, and the installers arrived on time and kept the place very clean throughout the whole process. They did a really good job and answered all my questions. I'm really happy with the final results! I can't thing of anything at this time.
Working schedule for 3rd party contractors that Interlock brings in for some of the job requirements. Thank you to the whole team at Interlock for a job well done. We love our roof and the snow guards:), Everything looks amazing. Looking forward to the next project with you all.
Definitely not the cheapest roof but looks good! The people worked hard during the hottest days of summer and cleaned up after the job was done! It rained heavily two days after the roof was finished! No concerns! Well done!
I would recommend that you do your surveys a little later in time or direct the questions that are more relevant to the time. You would probably get more useful data.
Absolutely would recommend their products & installation.
None at this time. Great overall experience with the entire Interlock team.
Absolutely. The only thing Interlock Roofing could improve on for our experience is the clean afterwards. Need to find a better way to get the majority of the little metal pieces that are all over the ground.
When I was doing the research on replacing my roof on my house, I was looking for a more environmentally friendly material and something that would keep my house cooler after a hot, sunny day. At one of the environmental fairs I attended, I picked up a brochure describing all types of roofing materials.
Interlock Roofing could improve on communication with the office staff and with the installation crew.
I liked the product but it was priced out of my ball park. The salesman did the very best that he could but it was not possible for me to pay that much money.
