Commercial Roofing Solutions for a Wide Range of Industries

Since 1946, GSM Roofing has served as the commercial roofing contractor of choice for some of the most demanding facilities in Pennsylvania, New Jersey, Delaware, and Maryland. Our clients operate manufacturing plants, healthcare campuses, educational institutions, and more — environments where a roof failure is not just a maintenance problem. It is an operational one.

We bring manufacturer credentials that most regional contractors can’t match: we are a Master Contractor for Elevate, an Elite Contractor for Sika Sarnafil, and hold over 1,000 Perfect 10 installation certifications with Carlisle SynTec. Our team includes NRCA ProCertified technicians, and our experience with specialty roofing runs deep enough that we were selected to help write the National Slate Association’s installation manual.

Every industry on this page presents its own roofing challenges. We’ve worked in them long enough to understand those challenges and to have solved them, repeatedly, for clients who needed a contractor they could trust to get it right the first time.

Frequently Asked Questions

Can You Work on Our Facility while It's Still in Operation?

Yes, active-facility work is standard for GSM Roofing, not an exception. We plan projects around your operational schedule and implement containment protocols for noise, fumes, and debris. For highly sensitive environments, like healthcare facilities or 911 dispatch centers, we coordinate directly with your facilities team to ensure work sequences never compromise operations.

What Roofing Systems do You Install for Industrial and Commercial Facilities?

We install the full range of commercial roofing systems, including TPO, EPDM, PVC, built-up roofing (BUR), modified bitumen, metal roofing, and green roofing systems. We are a Master Contractor for Elevate, an Elite Contractor for Sika Sarnafil, and hold Carlisle SynTec’s Perfect 10 installation certification, which means we can offer extended manufacturer warranties on qualifying installations.

Do You have Experience with Regulated Environments?

Yes. Our team has completed projects on surgical centers, hospice care facilities, and active government buildings, including facilities housing law enforcement operations. We understand the safety, documentation, and scheduling requirements that come with regulated environments and build those requirements into every project plan.

I did get a chance to inspect the roof of this church last week. There was no damage to the roof, it is actually in quite good condition since it was installed in the late 80’s or early 90’s. The leaks they are experiencing are at the flashing transitions to the stone masonry and one at a brick masonry chimney.

But I did want to tell you that I was very impressed with Austin, the young fellow that ran the lift for me. I am not sure I have ever had such a smooth and accurately-placed ride. It wasn’t the highest roof I ever had to look at, and maybe the equipment rental was newer, but still, it was refreshing to see the competence of that young fellow.
