Whatcom, WA
Our Bellingham office is at 2219 Rimland Dr, and Whatcom County is its home ground — 50 completed installations in Bellingham since 1998, with photographed work in Bellingham and Everson. This is Salish Sea country, and that makes the material decision straightforward. Salt air corrodes steel roofing at every cut edge, scratch and fastener hole; aluminum has no iron to oxidize, so it cannot rust. Our Guardian warranty carries no salt-air exclusion — a Blaine or Birch Bay roof on the water gets the same lifetime coverage as one in Lynden farm country.

I had a fantastic experience with Interlock Metal Roofing! Their team was incredibly easy to work with and very responsive to all of my questions throughout the entire process. I want to give a special shout-out to our installers, Victor and Daniel. They were extremely professional, friendly, and did an amazing job installing our new roof. The new metal roof looks absolutely amazing! I highly recommend them to anyone looking for a high-quality roofing experience.

2nd time around with Interlock, first time for house and now a few years later for my garage. Quality of product and installation are excellent and it matches the house roof perfectly. Expensive but in Washington what would you rather have a roof that last a lifetime or a 30year shingle that’s done in 10? The PNW is hard on roofs don’t keep paying!

We have completed with great satisfaction from Interlock our roofing in two separate locations. The install team is amazing headed in one location by "v" "V" answered all our concerns and questions on site honestly and correctly. it is a very expensive product but with the warranties and profession install we are more than satisfied.

We needed a small repair on our roof and Ivan came quickly. The repair was done quickly. Ivan explained everything he’d done and answered other questions professionally. Great customer service; we would highly recommend this company. We love our roof!
