The Commercial Roofing Services We Offer in Lancaster County

By offering a wide variety of services, our team can address all of a business’s roofing needs under one roof. This comprehensive approach not only saves businesses time but also potentially saves money in the long run by identifying and addressing minor issues before they can escalate into larger, more costly problems.

Preventive Roof Maintenance Service Plans

By regularly inspecting your roof for leaks, deteriorating flashing, HVAC oil spills, and more – we can help maximize the longevity of your roofing system. Our service program also includes debris removal and guaranteed response time for leak repairs.

Curb Installs/Rooftop Penetrations

Roofing curb provides a secure mounting point for HVAC units, exhaust fans, skylights, solar panels, and other rooftop equipment. It also forms a tight seal, helping prevent roof damage and leaks.

Leak Repairs

We will work to fix the problem quickly and effectively. By addressing leaks early, property owners can avoid costly repairs, mold issues, and the replacement of damaged materials, preserving the value and integrity of the building.

Roof Snow Removal

Our team has the knowledge and equipment that’s needed to safely remove snow from a steep slope or low-slope roof. We can help prevent damage to your property caused by the roof collapsing.


Applying a coating to a roof can provide long-lasting protection, slow down aging, improve energy efficiency, and reduce maintenance costs. We work with a number of different coatings, so we can apply the right coating for your needs.


Using infrared technology and drones, we’re able to thoroughly inspect your roof and proactively identify underlying issues before they become an issue. We can detect leaks and water damage as well as mold and material deterioration.

Our Lancaster County Projects

Franklin & Marshall College Emergency Roof Blow-Off & Repair

F&M College in Lancaster, PA

We took on an extensive project to refurbish the roof of the historic Ben Franklin Dining Hall at F&M College. And when responding to an emergency call for a roof blow-off of the Alumni Sports & Fitness Center during a windstorm, we secured the lifting roof with concrete pavers and sandbags. We also repaired tears in the membrane roof and installed watertight termination points to ensure lasting protection.

Lancaster Plumbing, Heating, Cooling & Electrical

GSM Roofing installed new metal siding, gutters, and downspouts at their Enterprise Road location. The project also included front coping and EPDM flashing detail.

President James Buchanan’s Wheatland

Over the years, we’ve provided general maintenance and repairs for roofing on the property. When the mansion roof needed replacement in 2019, we had to balance new materials with old-world craftsmanship to preserve the mansion’s historical integrity and increase the roof’s life expectancy.

Maytown Reformed United Church of Christ

Preserving the church’s historical integrity was important to the congregation. So, we restored the historic roof, originally built in 1805, using North Country Black Slate with clipped corners to match the existing roof. And the new slate roof is designed to last 100 years.

St. Stephen Reformed Church in New Holland, PA

Paul Risk Construction repaired the leaning steeple at St Stephen Reformed Church. But GSM Roofing was called on to install a lead-coated flat seam roofing system to the base of the lantern, including custom-made urns and figurines. Additionally, GSM Industrial created a new spire for the steeple, which was fitted with a lead-coated standing seam roofing system before being put into place.

Windsor Mount Joy Insurance

This challenging project involved a full roof tear-off, installing tapered insulation and white EPDM, and replacing all existing rooftop units. Additionally, GSM installed custom storefront metal siding and trim as well as two Velux Modular Skylight Bays.

Linda Good, Maytown Reformed UCC
LancasterHistory is grateful for the work and care provided by GSM Roofing at Wheatland. As an historic mansion, and the home of Pennsylvania’s only United States President, Wheatland required special attention, down to the smallest detail. It’s a delight to look up and see the new roof and know that Mr. Buchanan would be proud.
Robin Sarratt, Vice President
The work was completed perfectly and on time. I'm very satisfied with GSM Roofing and would definitely recommend them.
