COSTARS Registered Supplier
Registration Number: 008-E23-1112
GSM Roofing is a registered COSTARS supplier through the Commonwealth of Pennsylvania. COSTARS is a cooperative purchasing program administered by the PA Department of General Services that allows Pennsylvania public entities to contract directly with pre-approved suppliers without conducting a separate competitive bid process.
If your organization is a Pennsylvania school district, municipality, county government, state agency, public university, or other qualifying public entity, you can hire GSM Roofing using our COSTARS registration. No separate bid required. No lengthy procurement process. Our registration number is 008-E23-1112.
This is a meaningful advantage for public-sector facility managers who need responsive, qualified roofing services and do not want to navigate a standalone bidding process to get them.
Awards and Industry Recognition
The following awards have been presented to GSM Roofing in recognition of project quality, craftsmanship, and industry leadership. These are competitive awards, not participation recognitions.
J.A. Piper Award
Presented by the Northeast Roofing Contractors Association (NERCA), the J.A. Piper Award is one of the most prestigious honors in the commercial roofing industry. It recognizes exceptional craftsmanship, project quality, and technical execution on completed commercial roofing projects. GSM Roofing has earned this award for work that demonstrates the highest standards the industry recognizes.
Grand Jury Award
The Grand Jury Award recognizes outstanding achievement in commercial roofing project execution. It is awarded to contractors who demonstrate superior technical skill, attention to detail, and quality of results across demanding project conditions.
Project of the Year
Awarded for excellence on a specific commercial roofing project, the Project of the Year recognition reflects exceptional performance in scope management, technical execution, and finished quality. GSM Roofing has received this recognition for projects that set a benchmark for what commercial roofing can deliver.
Excellence in Single-Ply (ESP) Program
The ESP designation recognizes contractors who demonstrate exceptional proficiency in single-ply roofing systems, including TPO, EPDM, and PVC membranes. It reflects both technical knowledge and installation quality across the roofing systems most commonly specified for commercial flat and low-slope applications.
GAF GoldElite Commercial Contractor
GAF’s GoldElite designation is the highest tier of recognition in GAF’s commercial contractor program. It is awarded to roofing contractors who meet rigorous standards for training, installation quality, and customer satisfaction. GoldElite contractors are authorized to offer GAF’s strongest commercial warranties, including the Golden Pledge warranty, which provides coverage backed directly by GAF rather than the contractor alone. For building owners, hiring a GoldElite contractor means access to warranty protection that is available through only a small percentage of commercial roofing companies.
Industry Affiliations
GSM Roofing maintains active membership in the following organizations. These are not passive memberships. They represent ongoing training, compliance, and participation in the standards that define professional commercial roofing.
Associated Builders and Contractors, ABC Keystone Chapter
ABC Keystone advocates for merit-based construction and open competition in commercial contracting. The chapter provides safety training, workforce development programs, and government representation for commercial contractors across Pennsylvania. GSM Roofing’s ABC Keystone membership supports our ongoing investment in workforce safety and skills development, both for our own team and for the broader commercial construction industry in the region.
National Roofing Contractor Association (NRCA)
The NRCA is the commercial roofing industry’s primary national association, setting standards for installation practices, safety protocols, and contractor ethics. NRCA membership requires ongoing engagement with industry best practices and continuing education. When a contractor is NRCA-affiliated, it means they are connected to the most current technical standards in the field, not working from outdated practices. GSM Roofing has maintained NRCA membership as part of our commitment to staying at the leading edge of commercial roofing.
North East Roofing Contractors Association (NERCA)
NERCA serves commercial roofing contractors across the Northeast, providing technical training, safety resources, and regional industry advocacy. The Northeast presents specific challenges in commercial roofing: freeze-thaw cycling, heavy snow loads, ice dam formation, and humidity-driven membrane stress. NERCA membership keeps GSM Roofing’s teams trained and current on the conditions specific to the Mid-Atlantic and Northeast markets we serve across PA, NJ, DE, and MD.
National Slate Association (NSA)
The NSA promotes excellence, craftsmanship, and sustainability in natural slate roofing, one of the most technically demanding disciplines in the specialty roofing trades. GSM Roofing’s NSA membership reflects our long history of slate installations and restorations on historic structures, landmark buildings, and institutional properties across the Mid-Atlantic. Slate work done incorrectly fails within years. Slate work done correctly lasts over a century. NSA membership is the industry’s signal that a contractor takes the difference seriously.
RoofConnect
RoofConnect is a national roofing services network that connects commercial property owners and facility managers with vetted contractors for large-scale re-roofing, emergency response, and multi-location portfolio management. For organizations that manage commercial real estate across multiple regions, RoofConnect membership means GSM Roofing is part of a network with the capacity to support complex, multi-site roofing programs. It also means GSM Roofing has been evaluated and approved against the network’s contractor qualification standards.
Roofing Alliance
The Roofing Alliance is the research and philanthropic arm of the NRCA, funding independent research into roofing materials, installation technology, energy performance, and workforce development. Membership in The Roofing Alliance reflects GSM Roofing’s investment in the long-term advancement of the commercial roofing industry, not just our own business. The research produced through the Alliance shapes the technical standards and best practices that define how high-quality commercial roofing is done.
