What Our Clients Have to Say

Professionalism, Punctuality, Quality, and Responsiveness

I have only good things to say about GenEx as a contractor. From my initial calls with Greg, through to the 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.

Greg came out to my place to do a roof inspection. He was very thorough and advised us of all of our options, even including the option of waiting to replace our roof. You could tell he wasn’t just trying to sell a job, but provide honest options available. He even did a roof repair for free for us! He advised us on what to look for should future issues arise that may require attention and, most importantly to me, he advised on what not to lose sleepover. He was reassuring, telling us what to do to protect and maintain our home. He really took his time and even looked at additional exterior concerns (such as my gutters) that I had, again, answering all of my questions. I highly recommend them! The office staff was friendly and they maintained contact for scheduling and responded immediately, respecting my work schedule as well, which I appreciated!

We needed our garage roof replaced, and I can’t explain how happy we are with the results. Our roof looks amazing, and Paul and his crew fixed everything that was wrong with it or that was not done correctly the first time, which was before we purchased the house. 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.

Cannot say enough positive about the whole experience with Gen Ex. From the inspection to the temporary fix and dealing with the Insurance company. The Contractors were professional and thorough also keeping the jobsite (my home) clean. Very large job complete roof and extensive interior. Thank you

Gen Ex was absolutely amazing. We had storm damage that resulted in all new shingles and gutters. We had a ventilation issue and Gen Ex went above and beyond in replacing plywood and making sure the roof was vented properly. Thank you to Paul and the Gen Ex team!!
