MGS Construction put a roof on my home yesterday. The roof came out wonderful. It took one day and the clean-up was amazing. This company is honest and they work hard. I will be using them again when I decide to put new windows in. Thanks guys for a job very well done.

MGS did our roof in December 2014. They were great! In and out in two days with virtually no trace that they were there other than our new roof! I'll be calling than back to do our siding and other home improvements.

If you need a new roof, MGS Construction is the company to call. Reasonably priced and skilled craftsmen. They replaced our roof in one day and it looks fantastic! Very pleased with the results.
