Commercial Roofing Installation
We install asphalt shingle roofs for multi-family residential and custom office developments, and metal and TPO/EPDM roofs for commercial properties including office, service, showroom, tech, free-standing and strip centers throughout Dallas and the surrounding north Texas area.
TPO/PVC or EPDM - What is the best flat-roof choice?
The standard for commercial single-ply flat-roof style installations are either EPDM (Ethylene Propylene Diene Monomer) or TPO (Thermo-Plastic Olefin) /PVC (Polyvinyl Chloride). Each has its merits depending on the type of structure and the building's use.
General office/service/showroom, and warehouse facilities have a different requirement than an industrial-use building where chemicals are involved. For a new roof, we will help you determine that best type for your business' building. Your commercial application options replace the older BUR-type roofing process that consisted of layers of asphalt roofing materials and tar with a reflective gravel top layer application which was less durable and required greater maintenance than today's compound-based roofing process and materials. Three current roofing installations include the following:
EPDM roofing, of the three, has the longest, positive history. It has the look and feel of an everyday rubber inner tube. EPDM comes in large rolls and is well-suited to application over any large, flat roof surface, providing the substrate is clean and uniform. The flexible rubber material is glued to the roof substrate and to adjacent EPDM sections (installation with mechanical fasteners is also possible). An EPDM roof can easily last 20 years with minimal maintenance, but its dark tone absorbs a tremendous amount of heat. To prolong the life of this single-ply roof and reduce cooling costs, a reflective top coating is essential. Alternatively, you can pay extra for EPDM membrane with a white top layer.
TPO roofing is a light, affordable, fabric-like roofing, single-ply material option. Its chemical composition represents a newer roofing technology that’s still being refined by different manufacturers. The material comes in rolls of different sizes, making it suitable for a variety of flat roof projects. It can be installed with adhesives, mechanical fasteners or heat welding. Like EPDM and PVC roofing, TPO requires a clean, uniform substrate — it can’t be installed directly over existing roofing material. Although TPO usually costs less than EPDM or PVC, it doesn’t yet have the same track record of proven performance.
PVC roofing offers top performance for a premium price. This single-ply roofing material is made from polyvinyl chloride, the same high-performance plastic used in plumbing pipes. Like EPDM, PVC is most frequently used on larger commercial roofing jobs. Seams between PVC sheets are welded together with a specially designed heat gun. The resulting membrane is impermeable to moisture, with excellent durability. Because PVC roofing is naturally white, it has excellent heat-reflective qualities without any coating or extra treatment.
