Reliant Roofing has experience with all types of roofs:


EPDM has been in use on roofs in the US since the 1960’s and is one of the most common types of flat/low-slope roofing materials. This is because it is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional Built-up roof systems. The odors and fumes that accompany built-up roofs are not present with single ply systems; this is very appealing to many owners of buildings.

There are three standard application procedures of EPDM:

(1) fully-adhered
(2) mechanically-fastened
(3) loose-laid

Fully-adhered EPDM uses water or solvent-based adhesives to adhere the rubber to the substrate. Mechanically-fastened EPDM is attached by manufacturer-approved mechanical means to the substrate, and loose-laid membranes are secured only at the perimeters and any penetrations.


TPO membranes are single-ply roof membranes constructed form ethylene propylene rubber. They are designed to combine the durability of rubber with the proven performance of hot-air wieldable seams. They have been tested as having excellent resistance to ozone, are algae-resistant, environmentally friendly and safe to install.

The material’s manufacturers are so confident in properly welded seams that the material is sometimes advertised as a monolithic (seamless) roof. Seam strengths are reportedly 3 to 4 times those of EPDM’s adhesive and tape seams. TPO is highly resistant to tears, impacts, and punctures with good flexibility to allow for building movement.

TPO’s are most common in white; however, many more colors are available, with thicknesses of 45 mils (.045”), 60 mils (.060”), or 80 mils (.080”). The width of the membrane depends on the manufacturer but they usually come in widths of six to six-and-a-half feet and are one hundred feet in length. TPO is the most common single-ply system used here in Florida.


PVC membrane is a roof membrane composed on only one layer of material, polyvinyl chloride. PVC roof systems are specially designed to withstand ponding water – PVC membrane is welded together with hot air (no open flame) to eliminate all seams so moisture cannot pass through, just like TPO systems. PVC roofing systems also reflect nearly 90% of the heat of the sun, thus lowering energy costs substantially, especially in high-heat areas such as the southwestern United States. PVC’s are available in 50 mils, 60 mils, and 80 mils, and in sheet width up to 78”.


As a property owner or manager, there are situations when you must have a new roof. Yet, there are other situations when options are available to use liquid-applied coating systems that can extend the existing roof’s life, with a WARRANTY.

Reliant Roofing offers a complete product line of coating systems that can virtually be applied to any type of existing roof surface. Coating systems form a durable, continuous membrane over the existing surface of the roof, forming a seamless, watertight seal over the entire roof, including all penetrations. Some of the benefits are included here:

  • Versatile – Formulated to restore virtually all type of existing roof systems
  • Proven – Millions of square feet of coatings applied each and every year
  • Conserves Cash – Can save up to half the cost of a new roof—while adding up to 20 years of life to your existing roof
  • Energy Savings – Reflective white surface can save energy—up to 50% or more of the roof’s original cost
  • Guaranteed – NDL warranties can be given up to 20 years
