COMMON QUESTIONS

ROOF REPLACEMENT QUESTIONS

How much does commercial roof replacement cost?

Commercial roof replacement typically costs $4-$12 per square foot depending on the roofing system, roof size, complexity, and current condition. A 10,000 sq ft flat roof replacement might range from $40,000-$120,000. Contact us for a free detailed estimate specific to your project.

How long does a commercial roof replacement take?

Timeline varies based on roof size and system type. A typical 10,000 sq ft commercial roof takes 3-7 days for installation. Larger projects may take 2-4 weeks. We work around your business schedule to minimize disruption.

What types of commercial roofing systems do you install?

We install all major commercial roofing systems including TPO (Thermoplastic Polyolefin), EPDM rubber roofing, PVC membranes, modified bitumen, built-up roofing (BUR), metal roofing, and green roof systems. We are certified installers for American Hydrotech, Siplast, and GAF.

How long will my new commercial roof last?

With proper installation and maintenance, commercial roofing systems typically last 20-30+ years. TPO and PVC membranes last 20-30 years, EPDM 25-30 years, and metal roofing 40-50+ years. We provide comprehensive warranties on all installations.

Will my business need to close during roof replacement?

In most cases, no. We work around your schedule to minimize disruption. We can work during off-hours, section the roof to maintain access, and use safety protocols that allow continued operations. We create a custom plan for your specific situation.
