Interlock® Aluminum Roofing — all-climates performance specs for Lochsloy, 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 very pleased with the look and style of the roof! This is my second Interlock roof and the quality is built to last! Nothing comes to mind. This is my second roof with Interlock. This roof is tucked away, so not many people get to see it. But when someone comes down the driveway, they really notice the roof now!
We are getting compliments from all of your neighbors on how great our roof looks. We rated the experience as high as possible
We would like to commend Interlock for your product and service. Our house is 1572 square foot ranch style home. It took two days to install the new roof. No mess no waste. The installation crew was very polite and professional. They didn't mind me supervising (watching) or asking questions. Interlock Roofing works as advertised. We have had a wide variety of weather in the last 50 days, heavy rain, hail, and eighty-degree temperatures.
They could have improved the final cleaning. Ross said the installation would only be 2-3 days but it took a week. I was not satisfied about that.
They did well. We were given information on how other roofs are put together, so it was an easy decision because of how Interlock Roofing roofs are designed. I work with a background in construction, and the only thing I would advise is that during the build they take photos of the progress and assemble a closeout package that way the homeowner has something to look back on to reference and if they sell the house they can transfer that as part of the warranty for the new owner.
The crew didn't know until that morning they were coming over to my project.
Communication when problems arose was slow and scheduling with office staff was difficult.
All went according to the installation plan and since no one can control weather conditions I can't think of anything to improve. Interlock has a very satisfied customer here!
Our installation crew got sick, so it took a lot longer than it was supposed to, but obviously that is understandable. That is the only thing that Interlock Roofing could have improved during our project.
If you promise a gift card for having a salesman over, follow through. No card
C O M M U N I C A T I O N. Our sales rep sold us and never called us again. Disappointing. He said he would be in touch with us. He lied. I became concerned and had to call the company. Never once did I receive a call about when the installation would happen. Never once did I receive a call thanking is for our very large purchase. Product is excellent. I am happy with my new roof.Installation guys were excellent. They deserve a bonus or a pat in the back.Financing gentleman was perfect.Sales guy and communication from Interlock not so good.Thanks kelly If your overloaded and can't make sure you are conveying gratitude then you need to hire someone who can make sure that happens.If you are hiring for sales and or Customer Service please call me.425-260-8512
