When you hire GSM Roofing to inspect and repair your commercial roof, you are doing everything you can to make sure you get the full benefit of your roofing investment.
Of course, there will be times when roof replacement is necessary—but with our repair options, we are hopeful that it happens much further down the road than you expect.

Commercial Roof Maintenance FAQs
What does commercial roof maintenance include?
A commercial roof maintenance program from GSM Roofing typically includes biannual preventive maintenance inspections, debris removal from drains, gutters, and scuppers, inspection of ancillary rooftop items, targeted repairs to address problem areas, roof coating application to extend surface life, and detailed condition reports with cost proposals for any additional work needed. We also offer roof snow removal to protect your building during winter months and roof curb installation and maintenance for buildings with rooftop HVAC units, fans, vents, and skylights. Programs are customized to your building’s roof type, age, and specific needs.
How often should a commercial roof be maintained?
GSM Roofing recommends a minimum of two maintenance visits per year, typically in the spring and fall. Fall maintenance is especially important in Pennsylvania, New Jersey, Delaware, and Maryland, where freeze-thaw cycles and heavy snow loads can cause significant damage to roofs that have not been properly prepared. Older roofs or those with existing conditions may benefit from more frequent visits.
What is the difference between commercial roof maintenance and a roof inspection?
A roof inspection is an assessment of your roof’s current condition. It identifies existing problems and potential areas of concern and results in a detailed report and repair recommendations. Commercial roof maintenance goes further, it includes the inspection but also involves hands-on work such as debris removal, minor repairs, drainage clearing, and coating application. Think of an inspection as the diagnosis and maintenance as the ongoing treatment.
What types of commercial roofs does GSM Roofing maintain?
GSM Roofing maintains all types of commercial roofing systems across flat, low-slope, and pitched roofs, including TPO, EPDM, PVC, built-up roofing, metal, shingle, slate, tile, and cedar. With nearly 80 years of experience and two locations serving the mid-Atlantic region, our team has the expertise to maintain virtually any commercial roofing system.

How much does a commercial roof maintenance plan cost?
The cost of a commercial roof maintenance plan depends on factors including the size and complexity of the roof, the roofing material and system type, the current condition and age of the roof, the number of inspection visits included, and the geographic location of the building. Contact GSM Roofing for a quote tailored to your building’s specific needs.
What happens if a problem is found during a maintenance visit?
