What Our Clients Say
“Garden State Roofing replaced our entire 12,000 sq ft flat roof on time and on budget. Their crew showed up every day, kept the site clean, and the finished TPO system has been completely leak-free through two NJ winters.”
Robert A.

“We had an emergency leak at 11pm on a Friday. Garden State answered immediately and had a crew on our roof within two hours. Incredibly responsive and professional. They fixed the issue and followed up the next week to do a full inspection.”
Patricia V.

Roofing Services
Knowledgeable in all new and legacy roofing systems — we'll recommend the best solution for your building.
TPO Roofing Systems
Thermoplastic Polyolefin single-ply membranes offer outstanding energy efficiency, heat-welded seams, and resistance to UV, chemicals, and punctures. Ideal for NJ commercial properties.
EPDM Rubber Roofing
Highly durable synthetic rubber membrane perfect for large commercial flat roofs. Excellent resistance to extreme weather — critical for New Jersey's harsh winters and summer heat.
