“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.”

Tina R.

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.”

When it comes to your roof, getting things done right is incredibly important.
You can rely on Gen-Ex to be your residential roofing specialist in nearby McHenry, IL. Whether your roof needs minor repairs or a total replacement Gen-Ex has the necessary tools and experience to provide superior results. A new or repaired roof adds value to your home and increases its curb appeal. A small leak or missing shingles might seem like a reasonable project to try on your own but you may miss something that will lead to a bigger (and more expensive) problem. In addition there are safety risks in trying to repair or replace a roof yourself. Working on roofs and hauling materials up and down ladders is dangerous if you’re not experienced. We have the equipment to perform the job safely and efficiently.

There are specific things to look for when questioning if your roof needs repairs or a replacement.
If your roof is over 20 years old it’s most likely time for a replacement. Cracked or missing shingles as well as curled shingle edges are also signs that you should call us.  The Weather in the Vernon Hills area is known to weaken materials which can be a leading cause to leaks, mold and rot. Gen-Ex values any roofing project, no matter how big or small and we go the extra mile to ensure that your project is completed correctly the first time.
