FAQs About Roof Replacement in Nassau County
How long does a roof replacement take?
Most roof replacements are completed in just one to two days, depending on the size and complexity of the roof. Our crews arrive on time, work efficiently, and ensure a thorough clean-up upon completion so your home is protected and looking its best without unnecessary disruption.
Can I stay in my home during the roof replacement?

What types of roofing materials do you offer?
Thermo-Seal installs a variety of high-performance roofing materials, including GAF asphalt shingles, standing seam metal, tile, and copper roofing. We’ll help you choose the material that offers the best blend of style, durability, and performance for your specific needs.
Do you offer warranties on roof replacement?
Yes, we offer industry-leading warranties through GAF and other top manufacturers. As a GAF Master Elite Contractor, we’re able to offer exclusive enhanced warranties that cover both materials and workmanship—providing long-term peace of mind.
What signs indicate I need a full roof replacement instead of repairs?
If your roof has widespread shingle damage, multiple leaks, visible sagging, or has reached the end of its expected lifespan (typically 20–30 years), a full roof replacement is likely more cost-effective and reliable than ongoing repairs. Our experts can evaluate your roof and recommend the best course of action during your free consultation.

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!
