Why Thermo-Seal Stands Out Among Recommended Roofers in Long Island
Not all companies marketing themselves as recommended roofers on Long Island can match our standards. At Thermo-Seal, we’ve built a 40+ year track record based on integrity, dependable workmanship, and customer-first service. We take pride in getting the job done right—and never cutting corners.
Every roofing project is completed by our in-house professionals, not subcontractors. That means better communication, reliable scheduling, and consistent results. As a GAF Master Elite Contractor—a status fewer than 2% of roofers nationwide earn—we’re held to the roofing industry’s highest standards.
From standard shingle roofs to custom systems, our materials are chosen for durability and performance in Long Island’s unique coastal and seasonal weather.

CLIENT REVIEWS
What Our Clients Are Saying About Us
Thermo-seal Windows provides exceptional customer service alongside high-quality products. Recently, I had the majority of my home's windows replaced by Aaron's team, and their performance was nothing short of impressive. They arrived on time, maintained a tidy work area, and dedicated themselves to ensuring a perfect installation of the windows.
Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
