The manufacturers that produce the roofing materials we install are much more than vendors; they are partners. They provide input for our recommendations, process and load our orders with care and educate our foremen and installers during training on new materials or for warranty certification. But most of all, we value the quality and integrity of the roofing materials and supplies they manufacture for the commercial roofs we install or repair.
Firestone Building Products
For more than a century, Firestone has been designing and producing innovative and proven commercial roofing materials for both single-ply membrane roofs as well as metal roofs. They manufacture a wide range of commercial roofing products including TPO roofing systems, RubberGard™ EPDM roofing systems, and metal roofing systems as well as the insulation and application products for these systems. In addition, we sometimes specify Firestone asphalt roofing materials for the asphalt and BUR roofs we repair. We are proud to be a Firestone Master Contractor.


Carlisle SynTec Systems
For over 50 years, Carlisle has been driving innovation and reliability in their area of specialization: single-ply commercial roofing systems. Little wonder, as their move to offer their EPDM pond-liners as the first single-ply membrane roof was, arguably, the foundation for membrane roofing. Their products include Sure-Seal EPDM, Sure-Weld® TPO, Sure-Flex™ PVC, and FleeceBACK® membranes which we recommend with confidence and assuredness. Every Quality Roofing Services installer is fully-trained in the Carlisle product line and certified for maximum warranty installations.
Johns Manville
Founded in a NYC tenement in 1858 by Henry Ward Johns, who used his wife’s clothes wringer and tea kettle to apply tar to cloth to produce its first roofing shingle, Johns Manville is now a leading innovator and manufacturer of commercial insulation and membrane roofing materials. Johns Manville provides the full spectrum of modern-day single-ply roofing options: EPDM, PVC and TPO roofing systems as well as insulation, cover boards, and adhesives. We are proud that our team has been trained in the JM product curriculum and are certified to offer the most robust warranty packages.


Englert Metal Roofing
Herb Englert, who founded Englert Metal in 1966, started as a manufacturer of aluminum gutters and pioneered the on-site rollform approach widely used today for metal roofing. We specify Englert Standing Seam, Architectural Metal and Structural Metal for many of the metal roofing systems we install. Our installation teams benefit from the training Englert provides for their products and are up-to-date on all requirements to provide the most comprehensive manufacturer warranty programs.
Merchant & Evans
Like Englert, Merchant & Evans is a specialist in architectural and structural metal roofing systems. With a tradition of engineering excellence and craftsmanship that stretches back to 1866, Merchant & Evans offers an advanced and highly diversified line of top quality metal roof systems, wall, fascia, and soffit profiles, perimeter edge metals, and component accessories to meet virtually any design requirement. QRS installers are fully versed in M&E’s product offering including ZIP-RIB, the world’s 1st structural standing seam roofing system.


GAF
North America’s largest roofing manufacturer providing both Commercial and Residential Solutions, we turn to GAF for their membrane roofing materials as well as their three-tab and architectural asphalt shingles whenever a job involves pitched-slope asphalt or is a hybrid project involving pitched-slope. All our personnel are fully up-to-date on GAF product installation techniques and are fully compliant for the most comprehensive GAF product warranties.
Versico
A division of Carlisle Construction Materials, Versico was formed in 1993 and has become one of the top three manufacturers of single-ply membrane roofing materials in the US. In addition to all commercial installation and insulation products, Versico is known for their flagship membrane products: VersiGard® EPDM, VersiWeld® TPO, VersiFlex® PVC, and VersiFleece® TPO and PVC.
