★★★★★

I'll be able to look at the roof a lot better when it is spring.

Barry, We want you to know how satisfied we are with our new Interlock roof. It is by far the best in appearance, warranty, workmanship and quality, bar none. The initial meeting with you (Barry Brinson) was excellent plus very informative to all our concerns. Kudos and recognition to the work crew of John C. Sr. + Jr., Tom G., Kelly G. and Mike B.

We had an interlock roof installed on our first home almost 20 years ago. We didn't want to replace the roof every 5 -10 years and 20 years later the roof looks just as good as it did the day it was installed. Very happy we went the interlock route.
