Commercial Roofing Information

Grandstaff Roofing & Siding’s philosophy is to install the best roof possible. No other company can provide a better roof installation, whether it is a large commercial low slope roof project, a small residential shingle roof or anything in between. Our staff has attended schools, seminars and on site training sessions in each system we install. We keep abreast of new concepts, systems and technological advances in the industry.  Our employees bring over 100 years combined roofing installation experience to the job site. We have selected a variety of quality roofing systems that meet the varied roofing needs in today's environment:

For LOW SLOPE ROOFING we use some of the best products available from several manufacturers:

Flintlastic by Certainteed

FLINTLASTIC roofing membrane is a premium, self-adhering SBS
modified bitumen roll roofing material suitable for use in accordance
with CertainTeed specifications for most low slope roof system
applications. Refer to the CertainTeed Commercial Roof Systems
Specification Manual for complete self-adhered roof system
specifications and application requirements.

EPDM by GenFlex

EPDM (Ethylene Propylene Diene Terpolymer) synthetic, rubber roof membranes
have been used on roofs in the United States since 1960. The properties of
EPDM - resilience; tensile strength; elongation; resistance to ozone, ultraviolet light
and ponding water – make this membrane an excellent roofing material.

TPO by GenFlex

TPO (Thermoplastic Polyolefin) membrane, a high quality thermoplastic polyolefin,
offers the “best of both worlds”...the proven flexibility and weathering resistance
of rubber and the performance of hot-air welded thermoplastic seams. GenFlex
TPO membrane meets all the requirements of the new TPO ASTM Standard D 6878-03.

RM (PVC) by GenFlex

The PVC (Polyvinyl Choride) 12-foot wide sheet is the industry's first 12' wide PVC roofing membrane, offering significant benefits, especially when combined with GenFlex patented dual-weld seaming technology. There are fewer seams to weld and fewer fasteners to install.

For METAL ROOFING/STANDING SEEM ROOFING, the longest lasting roofs on the market are seemed metal roofing systems from:

Structural Standing Seam by ATAS

Double locked standing seam panel system. They are installed with concealed clips and
fasteners, mechanically seamed in the field. Panels are available in smooth or embossed
texture, and in 29 standard ATAS colors with KYNAR 500® or HYLAR 5000® finish.
