Aluminum does not develop iron rust
- Coastal salt-air corrosion resistance tailored for South Kitsap shorelines — aluminum coated with the Alunar® Coating System (no visible aluminum surface) to limit corrosion from marine exposure.
- Designed for atmospheric-river events that impact Kitsap County: reinforced seams and drainage detailing help manage extreme, sustained rainfall.
- Controls moss and organic growth common on damp South Kitsap roofs through non-porous coated surfaces and steep-shedding panel geometry.
- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Tested wind performance to 120+ mph (193+ km/h) for resilience against Puget Sound storm gusts and seasonal windstorms.
- Snow-shedding metal panels reduce snow buildup and mitigate freeze–thaw and ice-dam risk during occasional Kitsap winter storms.
- Class A fire-rated available for added protection against ember exposure during local wildfire or brush-fire threat periods.
- UL 2218 Class 4 impact resistance for protection from hail, falling limbs, and storm-borne debris typical in Pacific Northwest storms.
- Engineered cool-roof performance to lower attic temperatures and reduce heat gain during summer heat waves in South Kitsap.
- Compatible with bracket-mounted photovoltaic systems so homeowners can integrate solar without compromising roof integrity.
- Low-maintenance finish resists flaking and staining in high-humidity Kitsap County conditions, reducing routine upkeep versus asphalt shingles.
- Sustainable, fully recyclable aluminum construction supports long-term environmental stewardship for South Kitsap properties.
- Multiple architectural profiles replicate slate, cedar shake, and tile to match local aesthetic requirements while providing metal durability.
- Mechanical standing-seam fastening provides a secure, low-profile attachment that minimizes panel lift and wind intrusion on exposed coastal slopes.
- Backed by a Lifetime-Limited transferable warranty to preserve resale value and long-term protection for homeowners across South Kitsap.

Interlock® Aluminum Roofing — all-climates performance specs for South Kitsap, 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 the Interlock Roof installed in November of 2015 since then we have had some torrential rains and winds exceeding 50 mph. The roof has weathered the storms and is just as sound as the day the workers completed the installation. We are extremely pleased with the roof and the appearance of the roof. We are also very pleased that we chose the Interlock roof, both for the appearance and the wear ability of the product. It is a huge relief for us to know that this is the final roof we will ever have to put on our house and that the product is backed by a lifetime warranty. Your roofing specialists that installed the roof were very professional, considerate, and thorough in their work.
We are DELIGHTED with our new roof! The day after it was completed, we had a windstorm. It was so wonderful to wake up knowing there would be no shingles in the yard or loose shingles on the roof. And it is BEAUTIFUL!
Interlock Roofing looks awesome but is expensive!
Interlock Roofing could have improved follow through with customer service. We love the roof, and other than the small hiccup with the installation date, everything went well.
I have had this roof for almost 7 years, and I am still extremely happy!
“No Worries”, may be an “in” thing to say now days, but for us it is a reality for the next 50 years! This summer, we didn’t worry about the bottle rockets landing on our roof. This fall, we won’t worry about the shingles blowing off in the next 60 plus mile an hour wind. This winter we won’t worry about the snow. And in the spring, we won’t worry about the moss growing on on our roof. If you are thinking you want a roof like ours, no worries about the salesman pressuring into something you don’t want. They were very professional and nice. Everything they promised was delivered exactly as they promised. You will also have no worries when it comes to the installation, as they too were very professional and left the yard just as they had found it. No worries also when it comes to our carbon footprint, as our existing roof is still on our roof and not in a landfill and when the day comes to replace this roof it is recyclable. They really should rename the Interlock Roofing to No Worries Roofing. “No Worries” in Bremerton
The end of the project could be more definitive. I'm still waiting for them to come take pictures of the roof. I don't like the open end of that because they haven't taken the photos yet. We are super happy with the roof. It is gorgeous! We are so excited to have it. My only complaint, is that I want the photos done.
They did exactly what they were supposed to do, there isn't much to improve on.
Interlock Roofing could improve on their initial communication process, and details of the project could be explained in better detail.
Better coordination/involvement between Ross & the installers. To improve the transition process from the Sales Rep to the Installation Rep, so the customer knows that the sales and installation are on the same page.
I ran the numbers and I'm prioritizing this roof system. It costs more but it's worth it.
I think they could have better communication and better interactions with the homeowners about problem areas. I didn't get a notification that they removed the lean on the house.
