- Snow-shedding metal panels reduce heavy snow buildup and lower structural load risk on mountain homes around Denny Creek.
- Robust detailing minimizes ice-dam formation and resists repeated freeze–thaw cycles that affect roofs in King County mountain zones.

- UL 2218 Class 4 impact resistance helps protect against hail, falling branches, and storm debris typical of Cascade-adjacent properties.

- Low-maintenance finish and interlocking design reduce routine upkeep compared with asphalt shingles in the damp, moss-prone Pacific Northwest.

Interlock® Aluminum Roofing — all-climates performance specs for Denny Creek, 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 had some previous knowledge about the Interlock Roofing system as our neighbor had one installed in 2001. It looks fantastic and has held up beautifully so the decision was fairly easy. We enjoyed having Paul Wright out to give us the low down on the product and is very personable as well. Even my shy pooch gave him much attention & Paul shared plenty of scratches. We were replacing a 20 plus year old roof on a 1935 home. The crew was amazing, it must of been the hottest week in May & they worked many long days the hot roof. We are getting so many compliments on the roof so we know we made the right choice by having this amazing Interlock roof installed! Not at this time Not at this time
It would have been nice to know the pricing of the skylights up front. It was very confusing when we were discussing them because there was a lot of back and forth. My house looks beautiful. The job was complicated and they did a great job.
I don't know that there was anything that could have been done better. It looks beautiful. I have had dozens of compliments. Everything is functioning well during bad weather. I give the entire experience an A+! I have to also add, Jonathan, our sales representative was also very charming, lovely, and easy to work with. Lastly, there was a lovely woman from British Columbia in the office who was very nice. The entire experience was very nice!
I liked their presentation. They had samples and were very knowledgeable and prepared.
The crew could have improved a little bit by better communicating their schedule, but every time that we asked them, they certainly told us exactly what was going on because they had some weather complications which were not their fault.
see above
I used them 10 years ago and I didn't have any problems but this situation is not good. They are not trying to fix the situation. The communication is one place they can improve by calling back their customers. I think they need to give a full disclosure of the products and the materials they used. I haven't been able to get a break down of the materials they used on my project. I just hope they really did my roof properly and didn't leave other pieces of rotten wood up on the roof covered up. I am hoping that the roof is done honorable and I am not having to contact them in 5 years with problems because they didn't put the roof up properly.
