What customers say in Castle Rock, WA
★★★★★We had an excellent experience the first time with Interlock so used them again when we moved to our new home. I can’t sing praises any higher. Mike Rasmussen sold us the first time and we were lucky to have him this time as well. May and Patrick are wonderful to work with. Gregory, our installler, worked hard to get the job done single handedly when his partner had a family emergency and couldn’t continue. Our roof is gorgeous and the neighbors are slowing to look. I would recommend Interlock any time and every time! My pics don’t do it justice.

★★★★★We are in the middle of a lawsuit because they destroyed our ceiling by not covering the unfinished roof when it rained. They could have improved by covering the unfinished roof when it rained. I am still waiting on my lawyer to see if they are going to honor the warranty. As I have said, now my roof is falling apart.
