Commercial Roofing Services We Provide in Chester County
Every service below is available to Chester County clients, with crews experienced in the building types and roofing systems common to this market.
Preventive Roof Maintenance Service Plans
Chester County’s mix of healthcare campuses, institutional buildings, and industrial facilities requires maintenance programs tailored to the specific demands of each building type. Our Exceptional Roof Protection Plan includes biannual inspections, debris and drainage clearing, targeted repairs, and a guaranteed 2-business-day response to any leak that develops between visits. Facility managers managing multi-building portfolios across Chester County use this plan to eliminate unplanned roof failures and extend the life of existing systems.
Our inspection team uses drone imaging and infrared thermal scanning to identify moisture intrusion, membrane separation, and drainage failures that a standard visual inspection cannot detect. Every inspection produces a written condition report and, where needed, a cost proposal for recommended repairs. Healthcare and institutional clients across Chester County rely on our inspection documentation for insurance compliance, capital planning, and warranty verification.
We repair all commercial roofing systems common to Chester County buildings: TPO, EPDM, PVC, built-up roofing, modified bitumen, metal, slate, tile, cedar, and shingle. Persistent leaks at flashing transitions, membrane punctures, drainage failures, and storm damage are all within our scope. Our goal on every repair engagement is to extend the life of the existing system, not replace it before replacement is necessary.
When repair is no longer the right solution, GSM Roofing provides commercial roof replacement and new construction across all roofing systems. As a GAF GoldElite Commercial Contractor, we offer GAF’s strongest warranty coverage through a certified installer. Our Chester County projects range from modern flat roofs to steep-slope institutional systems requiring specialty materials.
Chester County winters create structural risk for flat and low-slope commercial roofs. GSM Roofing provides commercial roof snow removal using OSHA-compliant procedures, coordinating with facility management to reduce load before it becomes critical. All work is documented for insurance and liability purposes.
HVAC contractors and facility managers throughout Chester County use GSM Roofing for roof curb installations on new and replacement equipment. We work around HVAC installation schedules, verify material compatibility with existing membrane systems, and warranty all labor and materials for one year.
GSM Roofing provides 24/7 emergency commercial roof repairto Chester County clients. Active leaks, wind damage, and storm events require immediate response. Call 800-532-ROOF at any time. Our Ephrata office gives us strong geographic coverage across the entire county.
GSM Roofing is a registered COSTARS supplier (No. 008-E23-1112). Chester County school districts, municipalities, county agencies, and state facilities can hire GSM directly without a competitive bid. Learn more about our certifications and affiliations.

Pennsylvania State Health Lab, Exton, PA
The PA State Health Lab in Exton has been a long-term GSM Roofing client, relying on our ongoing leak repair and maintenance services to protect the integrity of their EPDM rubber roofing system.

Healthcare facilities are among the most demanding environments for commercial roofing. Work must be scheduled around patient care, safety protocols are non-negotiable, and documentation is essential. GSM Roofing has completed multiple projects at Phoenixville Hospital including repair work, preventive maintenance, curb installations, EPDM low-slope construction, and roof coating, all without disruption to hospital operations.
Federal Mogul, Exton, PA
An extensive ongoing maintenance relationship with Federal Mogul’s Exton facility has included roofing and decking work, curb installations, insulation, target patches, seam plates, drain replacement, membrane and flashing repairs, and conduit waterproofing. Industrial facilities with complex rooftop equipment require a contractor who can manage multiple penetrations, equipment loads, and system compatibility. This is exactly the kind of work GSM Roofing was built for.

Projects at Coatesville Bible Fellowship have included roof repair, sheet metal repair, curb penetration installation, low-slope construction, full roof replacement, and steep-slope shingle installation. This project represents the breadth of what GSM Roofing handles: a single client with both flat commercial and steep-slope needs addressed by one contractor across multiple engagements.
What Chester County Clients Say About GSM Roofing
"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."
