Why we are different
For over 35 years, GenSun Roofing has been one of the most trusted names in roofing across the Northeast and Mid-Atlantic. Founded in 1990 and proudly headquartered in Hawthorne, New Jersey and supported by offices in 8 states, we have grown from a local roofing company into a regional powerhouse — with nearly 300 skilled crew members on the ground and more than 10,000 roofs successfully installed. From the first shingle to the final inspection, every project we take on reflects our unwavering commitment to quality, craftsmanship, and customer satisfaction.
We serve residential, commercial, and houses of worship across eight states — New Jersey, New York, Pennsylvania, Ohio, Connecticut, Maryland, Delaware, and Rhode Island — bringing the same high standards and personal attention to every community we work in. Whether you’re protecting your family’s home, your company’s facility, or your congregation’s sacred space, GenSun Roofing has the experience and expertise to get the job done right.
Our Three Divisions
Residential Roofing — Our residential division helps homeowners safeguard their most valuable asset with durable, beautiful roofing solutions built to last. We treat every home with the care and attention it deserves, delivering results that stand up to the toughest Northeast weather.
Commercial Roofing — Our commercial roofing team specializes in large-scale flat and low-slope roofing systems designed to protect businesses and industrial properties for decades. We understand the unique demands of commercial projects and deliver on time, on budget, every time.
GenSun Church Roofs — Through our dedicated GenSun Church Roofs division, we proudly serve houses of worship with the specialized care and reverence these treasured buildings deserve. We are honored to protect the spaces where communities gather, guided by the timeless words of Matthew 16:18 — “I will build my church.”
