Concept Roofing re-roofed my home in September 2014. “Mark” provided an on-site assessment and written quote for the job at $3200. He left a shiner brochure with a false claim of being a member of the Better Business Bureau and referencing a website that I later found out did not work. On the day of installation and after 1/2 the shingles were scraped off, Mark rang the doorbell and advised that the job will now cost an another $1000 because of an extra layer of shingles they had to remove. He then asked if I wanted them to continue. With 1/2 the shingles removed, there was no choice but to continue. Fast forward to spring of 2018! A leak started to show up in areas where Concept Roofing short-cutted in the number of layers of felt beneath the shingles. They also missed shingling a section of the roof at the back. They offered a five year warranty in the shiny brochure! I called in the Spring, left messages, and all were ignored. To future customers...stay away from this company.
