- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
- Interlocking panel system tested to 193+ km/h (120+ mph) to withstand severe coastal windstorms and Puget Sound gusts that affect Hat Island
- Alunar® Coating System — aluminum panels with no visible aluminum surface — provides multi-layer corrosion and UV protection for marine exposures
- Class A fire-rated available for homeowners seeking enhanced ember resistance and improved fire performance in Snohomish County risk assessments
- UL 2218 Class 4 impact resistance protects roofs from hail, falling branches and storm debris common to island properties
- Snow-shedding panel geometry reduces rooftop snow loads and helps prevent ice-dam formation during occasional freeze–thaw cycles
- Solar-ready profiles accept modern bracket-mounted photovoltaic systems without compromising the roof envelope or warranties
- Energy-efficient cool-roof performance reduces solar heat gain during summer heat waves and improves attic comfort on Hat Island homes
- Fully recyclable aluminum construction lowers lifecycle environmental impact in the sensitive Puget Sound ecosystem
- Precision-engineered interlocks and mechanical fastening minimize roof penetrations, lowering long-term leak and maintenance risk
- Low-maintenance finish resists typical moisture-related deterioration versus asphalt shingles in coastal Snohomish County conditions
- Transferable Lifetime-Limited warranty provides long-term protection and supports resale value for Hat Island properties
- Built to shed and seal through Hat Island’s atmospheric-river events and prolonged storm cycles, reducing ponding and leak potential
- Specifically formulated to resist salt-air corrosion and spray from Possession Sound, maintaining structural integrity on Hat Island roofs
- Because Hat Island’s persistent coastal moisture encourages moss and lichen growth, the Alunar® finish and near-smooth panel surfaces limit organic buildup and simplify cleaning

Interlock® Aluminum Roofing — all-climates performance specs for Hat 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:
I am totally pleased with my decision over 10 years ago to go with a 50 year Interlock Metal Roof! It has held up great to the test of time and when I am no longer on this mortal coil, my daughter, granddaughters or grandson will be benefitting from my decision!
There was miscommunication with Interlock itself. There was a start date that didn't happen. Materials were delivered but never taken off the truck. No one contacted me regarding that. I left a couple of messages and no one got back to me. We are really happy with the product.
That is the perfect roof because it is weather resistance, safe, and what can I say more? If I am going to live in this house forever, I would choose them.
My roof was replaced in November...in Washington, the installment guys were the best, they tarpped when needed, cleaned the yard each day. They were the best and so nice to work with.
Our Interlock Roof has now been installed three weeks and we couldn't be more pleased. Suffice to say we haven't yet experienced the winds and rains of winter, but we are enjoying a much cooler home interior.
Interlock staff does a lot of follow up over the phone, prior to, during and after installation. I wish there was an option to do follow up over email, website or even text messages.
There was a small issue between the communication of the project manager and me. I was unaware of the timing of it. They said that it would be shipped soon and then it was there. We did not have anyone there to receive it. We were fortunate to have a neighbor. It looks really good.
We needed the ability to communicate with our roofing crew. I am not going to be one of these people that says "They need to speak English" or anything. I suggest that the customer is at least given a phone number to text and the native language the crew uses and then we can use Google Translate to send simple messages back and forth. My wife and I really feel like communication can be improved a great deal. For example a good morning and good night text/email would be great. In the good morning communication you would say when you were going to arrive, who the point of contact for the day(Name, form of communication, etc) was and what they want to get done and what to expect including what time they were hoping to wrap up. In the good evening communication they would report what they got done, that they are done for the day, and what the next steps are.
There were problems that were encountered during installation. see #14
