Roofing Repair & Replacement in Cary, Illinois

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 Cary 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.
