Thermal Imaging
Thermal imaging inspections detect hidden moisture and structural issues using infrared technology. This non-invasive method identifies leaks, material defects, and insulation problems before they escalate. Ideal for preventive maintenance, it extends roof lifespan by enabling targeted repairs.
Roofing Solutions
We install and repair TPO, Modified Bitumen, and EPDM roofing systems. As Firestone Master Contractors, we offer 20-year warranties and specialize in cost-effective re-roofing solutions for industrial and commercial properties.
Maintenance Programs
Twice-yearly maintenance programs validate warranties and prevent failures. These services increase roof longevity by 50%, reduce emergency repairs, and optimize budget planning through early issue detection in facilities like schools and warehouses.
Emergency Repairs
Our dedicated team provides 24/7 emergency repairs for urgent roof failures. Rapid response minimizes damage to facilities, with union-certified technicians available to address leaks, storm damage, or structural issues at any hour.
Re-Roofing
We assess whether to repair, re-roof, or combine both approaches. Our experts evaluate existing systems to determine the most cost-effective solution, extending roof life while maintaining compliance with manufacturer warranties.
