Interlock® Aluminum Roofing — all-climates performance specs for Cedar, 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:
There are two reasons for this letter to you. First, both my wife and I wish to express our satisfaction with your roofing product. We are extremely pleased with the completed result and the enhancement to our home. Second, we wish to take this opportunity to commend your roof installer Mr. Larry Koster he is the kind of exceptional employee that any employer would be fortunate to have working for him.
When I decided I was gonna get a new roof, I knew it was going to be a metal roof. Meeting Randal at an outdoor show made it easier to start the process. He is both friendly and professional. The quote was straightforward. I got to see pictures of other houses and colors, and samples were brought.
Dear Interlock: We first saw this house just over a year ago we fell in love with it. At the time we realized the original roof, first growth cedar shakes, was due for replacement so we went hunting for some suitable material. When we saw the Interlock roof we sensed it had what was necessary to protect the house as well as compliment its character. Once we saw the results we knew we chose well. Once we started staying in the house we noticed when it rained there was an extra volume of water coming down the valleys where two main roofs came together. It was a small flaw perhaps in the original design but something which required a little ingenuity to remedy. Your installer Antonio managed to drop by just before Christmas to fix another small problem and fortunately a solution for the valley deluge. He managed to do just that a few days after Christmas on his way back up Island. It looks like his remedy is working. I guess time will tell if it lasts as long as the roof. Either way we would like to commend his efforts and thank you all for a job well done.
None that I can think of. They were great! Many thanks!!
I felt that Randal was very knowledgeable and helpful.
Yes, I would recommend Interlok Roofing to a friend and I have
They did a good job. It was good.
better waste collection from old roof tear-off.
We need to have our house resided before we can order a metal roof
Very good representation.
Always wanted a metal roof, love the look and even with our vaulted ceiling, there is no noise from the rain which everyone told us we would not like They could have insisted that they do the tear off and building the new roof so we didn't have issues with the delay, but hind sight is 20:20
They were professionals. I am getting a lot of comments of people liking the roof.
