About NexGen
Our History
NexGen Roofing Systems, LLC has over 20 years of experience. We have installed thousands of roofs, with different materials, sizes and conditions.
In those two decades, we learned to “read a roof” and spot even problems that other contractors miss. And most importantly, we know exactly how to fix it. Whether it be an awkward ridge line, a rotted section of plywood, or a chimney that has bad flashing—you can count on us to do the job quickly and cost-efficiently.
That’s why our customers always come back. They see the difference in our service and skill.
Our Philosophy
Tim Gannon has always told us: “The roof is one of the most important assets in a house. It protects the people and the property, and it must be installed properly every time.”
NexGen Roofing Systems never takes shortcuts or does shoddy work. Poor quality not only wastes time and money, but can cause structural damage and even create fire hazards. We always put your satisfaction and your safety first!
Our Promise
We may work on roofs, but we work for people. We understand your needs, and make sure there is always proper communication and clarity. Most people get “stressed out” by house repairs—we do our best to make sure that you’re not.
We also use high quality materials and state-of-the-art roofing equipment and technology. This means that the roofing job is completed faster, and the roof lasts longer.
