Commercial Roofing and Maintenance Services in Lancaster County, PA
Lancaster County is GSM Roofing’s home market. Our main office is in Ephrata, our crews know these roads, and we have completed more than 260 commercial and specialty roofing projects across the county since our founding in 1946. That is nearly 80 years of work on the roofs of Lancaster County schools, hospitals, historic landmarks, industrial facilities, churches, and office buildings.
Facility managers and property owners in Lancaster County who need preventive maintenance, inspections, emergency repairs, or a full roof replacement have a local partner with a track record they can verify. We are not a national contractor working from a regional outpost. Lancaster County is where we started, and it remains the core of what we do.

Our Lancaster County Projects
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.
Commercial Roofing Services We Offer in Lancaster County

Every service below is available to Lancaster County clients from our Ephrata office, with crews who are familiar with the local building stock, weather conditions, and institutional requirements specific to this market.
Preventive Roof Maintenance Service Plans
Lancaster County’s freeze-thaw cycles, ice loads, and summer storm activity are hard on commercial roofs. Catching problems before they become failures is what our Exceptional Roof Protection Plan is designed to do. The 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 Lancaster County use this plan to extend roof life and reduce unplanned capital expenditure.
Our inspection team uses drone imaging and infrared thermal scanning to identify moisture intrusion, membrane separation, and drainage failures that are invisible to a standard visual inspection. Every inspection concludes with a written condition report and, where needed, a cost proposal for recommended repairs. Lancaster County clients receive the same detailed documentation used by institutional buyers and insurance carriers to evaluate roof condition.
From a single failed flashing detail to storm damage across an entire membrane system, GSM Roofing repairs commercial roofs of every type found in Lancaster County. TPO, EPDM, PVC, built-up roofing, modified bitumen, slate, tile, metal, cedar, and shingle. If the roof can be repaired rather than replaced, we will repair it. Our goal on every repair engagement is to extend the life of your existing system, not sell you a replacement before one is necessary.
When repair is no longer the right solution, GSM Roofing provides full commercial roof replacement and new construction across all roofing systems. From large industrial flat roofs to steep-slope buildings requiring slate or custom metal, our replacements include manufacturer-backed warranties. As a GAF GoldElite Commercial Contractor, we also offer GAF’s strongest warranty coverage available through a certified installer.
Lancaster County winter weather creates real structural risk for flat and low-slope commercial roofs. GSM Roofing provides commercial roof snow removal using OSHA-compliant procedures to reduce load before it reaches dangerous levels. We assess structural load limits, coordinate with facility management, and document all work for insurance and liability purposes.
HVAC contractors and facility managers throughout Lancaster County rely on GSM Roofing for roof curb installationson new and existing equipment. We work around HVAC installation schedules, ensure material compatibility with existing membrane systems, and warranty all labor and materials for one year.
Active leaks, wind blow-offs, and storm damage require immediate response. GSM Roofing provides 24/7 emergency commercial roof repair to Lancaster County clients. Call 800-532-ROOF any time. Our Ephrata office gives us the fastest possible response time to emergencies anywhere in the county.
