TPO

Thermoplastic Polyolefin

TPO is one of the three different single-ply commercial roofing systems. TPO comes as a rubber roll that is rolled out and applied mechanically with screws or fully adhered with glue. White is the most common color due to its ability to reflect heat, giving you a more energy efficient roof.

PVC

Poly Vinyl Chloride

This single-ply roofing membrane looks the same as TPO, but does not have the same elasticity as TPO. PVC roofing systems are best used on restaurants or other buildings requiring high chemical resistance.

EPDM

Ethylene Propylene Diene Monomer

EPDM is another single-ply roofing membrane. This system is black and can be adhered around the perimeter and ballasted with gravel rocks. EPDM has the greatest elasticity which gives it the longest lifespan if properly maintained, but is not energy efficient.

Built Up Roofing Systems

The layers of a built up roof consist of felt and tar. Additional layers must be applied and maintained every year. If not maintained, this type of roofing system will not last long.

Modified Bitumen

A modified bitumen roof system can be applied hot (with a torch) or cold (just by letting it cure over time). Both provide superior quality and protection. the material used is called Ruberoid and is an asphalt-based product with rubber elements added to it.

Metal Roofing

There are two types of metal roofs: Standing Seam and R-Panel. The difference between both is that standing seam doesn’t show fasteners and R-Panel does. Metal roofs have a greater life expectancy, but can not be applied to a flat roof.
