Commercial Roofing Services We Offer in Chester County

At GSM Roofing, we understand the significance of a well-maintained roofing system in safeguarding your investment and ensuring the safety and comfort of the building’s occupants. Trust us to provide the services you need to keep your commercial roof in optimal condition, ensuring longevity, performance, and peace of mind for years to come.

Preventive Roof Maintenance Service Plans

This proactive solution helps business owners prevent common roofing problems, such as leaks, water damage, and deterioration caused by weathering and wear. Our plan includes biannual inspections, debris removal, guaranteed leak response times, and more!

Curb Installs/Rooftop Penetrations

Roof curbs provide support for HVAC units, exhaust fans, and skylights. When installed by professionals, these frames can support this equipment while also protecting the roof membrane from damage. 

Leak Repairs

Identifying and repairing leaks promptly can prevent water damage, structural deterioration, and potential disruptions to business operations. Our professional roofers conduct thorough inspections to pinpoint the source of leaks.

Roof Snow Removal

Our team uses specialized equipment and techniques to safely remove snow and ice from rooftops, preventing leaks and collapses. Regular snow removal helps ensure continued performance of commercial roofing systems.


We can apply a white coating that will not only help keep your building cool; it will also extend the longevity of your roof. The coating’s flexibility allows for movement, preventing cracks and tears, while it reduces maintenance needs.


Using drones and infrared technology when applicable, GMS Roofing can provide a comprehensive evaluation of the roof’s condition, identifying any signs of damage, deterioration, or potential issues that may compromise its performance.

What Our Customers Say

I don't know of ANY other contractor, in any other trade, that I have ever encountered that keeps me as informed as your company, specifically, Karla sending constant update emails to me. I also want to give credit to Will and Eric, as Karla may not even know the updates without them keeping her updated! Of course, all of the roofers that are on site making the repairs, which I don't know their names, but I appreciate their hard work!
