Our new Interlock Roof is beautiful. And our neighbors have noticed. The whole process was very professional from beginning to finish. Victor, Daniel and Patrick were incredibly efficient, courteous, knowledgeable, and hard-working. Would recommend highly.

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.

great job

Crew was amazing, we had one main house roof and two porch roofs that needed to be done fast and before the rain and they handled it well! Our metal roof got finished in two days and they came back out again to clean up on the third day and wrap up everything. We highly recommend them and their service as everything turned out great! Edit: I forgot to mention, we worked with a few different people but I believe it was Patrick and his crew whom helped us

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.
★★★★★
Maybe the best decision we’ve ever made. Looks incredible ! The roofers (Victor and Daniel) were pleasant and did an amazing job. They were kind and courteous and very tidy. Totally worth the expense. I would recommend them to anyone.

I had a very good experience with Interlock. From the initial presentation to the installation, I was very impressed with the knowledge and thorough nature of each step. The finished product looks beautiful too! To know that I have a lifetime warranty on my 'forever home' is incredibly peace giving. If a company offers you a lifetime warranty on everything but the color (that warranty expires after 30 years), you know they will do all they can to make the finished product perfect! My ONLY reason for not giving 5 stars was that during the estimate, we were told we'd need to replace plywood due to mold. When it came time to actually install the plywood, they needed to double the amount required which increased our bid by over $2K. Obviously I wish the original estimate had been more accurate. That said, our attic now has the correct amount of ventilation, fresh plywood with no mold, protected skylights and solar tubes and a beautiful finished product. I'm very happy! If I could give 4.5 stars, I would!
