Gooding Simpson & Makes
GSM Roofing is a private, family-owned, professional service company, specializing in the installation and maintenance of commercial and specialty roofing. Founded in 1946, we operate in the South Central & South Eastern PA, MD, DE and NJ region with a full scope of services that includes roof service & maintenance, re-roofing, new construction roofing, historic restoration and custom metal fabrication.

GSM also offers roof safety solutions and other building envelope products. We believe the prevention of accidents and injuries is so important, that a safe working environment has precedence over productivity whenever necessary.
Services
GSM Roofing dates back to 1946, when Fred Gooding decided to pursue his dream of starting a roofing company. He moved from Philadelphia to Lancaster, PA and sold his car to pay for his first job materials. Fred hitchhiked to his jobsites until Bill Simpson - and his truck - joined the business venture.
We believe the prevention of accidents and injuries is so important, that a safe working environment has precedence over productivity whenever necessary. To ensure we provide a safe working environment for ourselves, and customers, GSM employs a full-time and fully dedicated Safety Director: Jim McDevitt.
Most of the work we do is based on function and performance. But every once in a while, our craftsmen get to deviate from the norm and create special works of art. The InsideOut Inspiration Gallery at our company's Ephrata, PA headquarters is one amazing example of what our team is truly capable of creating.
GSM Roofing is a company that's all about people. We are a family owned and operated company that cares about its employees as much as its customers. Many of our employees have been with us for decades. Along with our stellar reputation, we offer excellent wages, generous benefits and growth potential.
As a leading commercial and specialty roofing contractor that's been serving customers for over six remarkable decades, GSM Roofing is passionate about handling your roofing and related needs with quality, safety and great service. Our long-standing customers consider us the one partner they can turn to when they have a roofing challenge.

Troy & his co-worker went above and beyond while working the past few weeks at our administrative building, Berwick Industrial Development Association (B.I.D.A.). These two gentlemen were not only courteous, professional and friendly, but they were willing to go that extra mile. We highly recommend them and hate to see them go!
GSM Roofing is very lucky to have Troy and his co-worker as part of their team!! 5 stars +
ALSO - after seeing several other reviews, we must note, the guys ALWAYS wore their masks while in and out of our building! Very respectful.

Three GSM employees with logo shirts, driving a GSM logoed truck, were maskless in the convenience store I visited this morning, despite a BIG FAT SIGN requesting a mask as a condition of entering. If they are so thoughtless about others in public, I would not trust them to do my roof. "I do not care about you" was embossed across their foreheads.

Rude and ignorant. Tried to run us off the road, playing games on the PA TURNPIKE. not a good look when your company logo is on the truck. Grow up. I'd never use this company just based on their poor behavior. Probably a bunch of careless 20 year olds.

They pressured us into doing the work immediately without a proposal because "they were in the area" then proceeded to charge 4 man hours of travel on top of a 4 man hour job which really should have only been 2 man hours. When correction of travel time was requested, they only reduced it by 1.5 man hours, meaning we are still holding the bag on… the majority of travel time. Not to mention, I can only assume they charged the customers before and after us for the inappropriate amount of travel time as well. Not to be trusted! No GSM we will not be using you in the future.
