Client Testimonials

True Professionals

Sep 01, 2014 by Phil Mullins

The CLS Roofing team were completely professional and courteous, and they got the roof replacement job done right. They cleaned up the site completely after they left, and the process went smoothly from the very beginning.

The Very First Job

Jun 14, 2014 by Pete Lemieux

Since the very first job I hired CLS Roofing for, which was a flat roof upgrade, I always call them for all my roofing needs. They do an excellent job every time, without any hassles. They are on time and clean up after themselves. Great service.
