What Our Clients Says...

Bryan Bredeson
G&S came highly recommended from our contractor and we now see why. From our first communication with Kelly (Estimator) until the end of the roofing job everything ran smoothly, and the job came in exactly at the estimated price. They were able to fit us in while we were out of town and we came back to a house and yard that was as clean as when we left. They also sent pics of the progress and condition of the framing/plywood - very nice touch. We couldn't be happier with the work!
Linda Novello
This is the second house we have used G & S. They came out after Hurricane Irma to look at our roof and leaks. David Steele had guys here within days as more rain was expected! They did a temporary fix and after looking at all damage (and dealing with insurance company) they replaced our upstairs windows, siding and fixed a ceiling they cut open! Always on time! Always great courteous crew! They are the best
Kellen Kayla
I had G&S re-do my roof after the hurricane last October. From the first contact to the final piece of scrap being cleaned up in my yard, G&S was nothing but professional. My roof looks amazing and they were very reasonably priced. I recommend them to everyone I talk to that needs work done to their home!
Megan Allen Burch
G&S replaced the roof of a home we purchased and did an excellent job. Competitively priced and amazing work. I would recommend this company to anyone. The office staff and communication with them was easy and enjoyable.

Our Journey

G&S Supply Co. was founded in 1990 by John Steele and his business partner, Cohen Gaskins Jr., but John’s path to entrepreneurship began much earlier. At just 18 years old, he started his working career as a helper on a beer truck for Pearlstine Distributors. After several years gaining hands-on experience, he moved on to Lowe’s Companies, where he continued building the skills and industry knowledge that would eventually lead him to start his own business.

In the early years, G&S focused on furnishing both materials and labor for builders and homeowners throughout the Tri-County area, carving out a niche in the exterior supply business. A few years after the company’s founding, Gaskins sold his share to pursue other interests. Reflecting on that time, Steele recalls, “We were so broke I couldn’t afford to change the name.” The G&S logo remained, and over time it became a familiar sight throughout the Lowcountry, with trucks rolling through neighborhoods and job sites. Even today, many customers still call the office for estimates saying, “I saw your truck.”

From the beginning, G&S has been a true family effort. John’s father, affectionately known as “JB the Gutter Man,” led seamless gutter sales, while his children, John David and Kelly, spent summers working at the distribution center. His brother Steven and several nephews also played key roles in helping build the company during its early years. As the business has grown, so has the next generation of leadership. Today, John David has taken the reins and is guiding G&S into the future, while John Steele has transitioned into a consulting role.

G&S Supply Co. now offers turnkey solutions in roofing, siding, decking, and seamless gutters, serving both residential and commercial customers. The company has also developed an exclusive exterior trim brand known as ExtremeWeatherPink. Easily recognized during construction on new homes, this distinctive pink trim has become an industry hallmark and is widely known as a G&S original. As Steele often says, “It’s amazing how many people recognize us as the Pinkwood guys.”

Operating from a distribution center in Summerville, G&S delivers products and services throughout the coastal regions from Bluffton to Myrtle Beach. With deep roots in the Lowcountry and a commitment to quality, G&S Supply Co. looks forward to continuing to serve the construction industry for many years to come—earning trust one project at a time, building lasting relationships, and remaining a dependable part of the communities it proudly serves.
