1 PLY SYSTEMS
Single-ply roofing membranes fall into two classes - thermoset membranes, such as ehtylene propylene diene monomer (EPDM) and thermoplastic membranes, such as thermoplastic polyolefin (TPO).
EPDM - an extremely durable and synthetic rubber roofing membrane (ethylene and propylene diene terpolymer) widely used in low-slope buildings. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold in a variety of widths, ranging from 7.5 feet to fifty feet, and in 2 thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specifically formulated tape.
TPO - a roofing membrane are blends or alloys of polypropylene plastic or polypropylene and thylene propylene rubber (EPR) or ethylene which is among some of the fastest growing commercial roofing products due to their many performance and installation advantages. TPO roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.
Barlow’s roofing is currently obtaining a license to purchase and certification to install both of these roof systems. Estimated single ply availability is Spring 2017.
2 PLY SYSTEMS
Modified Bitumen Roofing, commonly known as "torch on roofing," is a product with added rubber (SBS) to the bitumen, which allows it to be more elastic than bitumen. Our two ply system is a double heat applied installation, which means both layers of the membrane are heated and bonded to the substrate and the base layer respectively. This ensures that both membranes are fully bonded and create a much better seal opposed to a mechanically fastened system.
CURB INSTALLS
We work with new and current plumbing contractors installing roof curbs for RTU's, chimneys, vent stacks, pitch pockets, roof drains and exhaust fans. These types of curbs can usually be installed within a few days of booking. We can also remove curbs from discontinued units, or re-insulate and cap for future use.
