Low Slope Commercial Roofing Options

Wednesday, October 22nd, 2014


In the world of commercial roofing, there are countless ways to get the roof that best meets your business' needs. Chances are, if you manage, own or are building a large commercial building like a warehouse, you'll want a low slope or flat roof. Below are a few flat roof terms and options you may want to be aware of while looking for new commercial roofing.

Built Up Membranes
The two basic types of built up roofing (also known as BUR) have either coal tar pitch or asphalt used as a waterproofing element between plies of reinforcing felt. BUR roofs are literally "built-up”: they feature alternating layers of bitumen and reinforcing fabric.

Modified Bitumen (Mod Bit)
Modified Bitumen, or mod bit, is the recommended system for low-slope roofing. It consists of an asphalt and polymer blend which gives the material an elastic characteristic. This elasticity allows the system to expand and contract as the roof fluctuates due to temperature changes. It can be applied with a torch and adhesive (hot-applied) or self-adhered (cold-applied). After application, a roller is applied to remove all air bubbles between the base material and mod bit.

Single Ply
Single Ply roofing systems are a single ply of roofing material made from several types of polymer plastics and rubbers.

EPDM
EPDM is a type of synthetic rubber roofing with the added benefit of reducing water runoff pollution. The material can be loose laid and ballasted with pavers to hold the membrane in place, or it can be fully or partially adhered. A topping system may or may not be required by the manufacturer.

TerPolymer Olefins (TPO)
TerPolymer Olefins are fleece backed sheet membranes that are adhered to insulation. These products are typically white in color and may be reinforced. TPO roofing may or may not require a topping system.

Toppings
The roof systems above may require topping systems to hold the membrane in place, small river rock adhered with hot or cold adhesives, or a coating of some type. The toppings serve to protect the roof membrane from damage, Ultra Violet Light and general abuse.
