Great job and I highly recommend them. They were prompt, professional, and did the job before we thought they could even fit us in. We will definitely use them again if we need them.

I have only good things to say about GenEx as a contractor. From my initial calls with Greg, through to completion of the roof and siding project, he was knowledgeable, responsive and professional. The owners of the company (Paul and David) were on the roof with their crew ensuring the job was done right. I wouldn’t hesitate to recommend GenEx for roofing or siding projects.

– Denise M.

The company did a great job. They completed the work in a timely manner as promised. I would highly recommend them.
