TPO Roofing in Texas

Thermoplastic Polyolefin or TPO roofing is a type of single layer commercial roofing, with the other type being Ethylene-propylene diene polymer membrane (aka EPDM).  While the Single-Ply Membrane Roofing is a common roofing material, it also comes in different types to suit your facility requirements as well as budget needs. The difference between TPO and EPDM roofing systems is in their chemical composition, energy efficiency and how they are installed.

TPO roofing is one of the fastest-growing types of roofing convenient for flat roofs and, most notably, commercial buildings. This thin, economical roofing material is gaining popularity amid commercial businesses looking for reflective and durable roof that won’t lead you to loans or incur extra costs.

Installation of a TPO Roofing

Before installing a TPO roof, first, prepare the existing substrate through cleaning or removing the current roof, then install the insulation. Homeowners have the following types of insulation options to choose from:

Polyisocyanurate (Polyiso) – This insulation type is the most used when it comes to roofing applications. Although Polyiso is a little expensive, it pays off with a higher R-value rating.

Extruded Polystyrene (XPS) – This type of insulation is defined by the green, blue or pink colors. XPS insulation falls between EPS and Polyiso in terms of performance as well as price. It is also semipermeable and has a perm rating of 1.

Expanded Polystyrene (EPS) – this insulation type has the highest R-value per dollar. It is best floor, roof, and wall insulation. Expanded Polystyrene insulation is also convenient for ground contact, besides it does not retain water with time.

During the installation of the TPO roof membrane, a bonding adhesive can be used to attach it to the cover board, but it can also be mechanically fastened. If the TPO membrane is rolled out, the contractor can then use hot-air gun weld and keep the seams together.

Why TPO?

The main reason why you should choose to install a TPO roof on your flat roof structure is the price. It is one of the most economical roofing materials in market, as compared to EPDM or the other rolled rubber roofing types. Additionally, if you opt for TPO roofing, it would be because of its color. Featuring an authentic white top, TPO reflects the sun’s light and helps to avoid the buildup of heat inside the house.

Other irresistible advantages of TPO roofing include the many installation options it has; first, it can be heat-welded in areas around the chimney as well as other protrusions. Additionally, it can be directly fastened to the roof deck or attached using adhesives.

Another reason to install TPO roofing is that they resist break down and corrosion when it gets in contact with other materials. Besides, it doesn’t tolerate growth of mildew or algae and also doesn’t require pressure washing.

If you are going to purchase a TPO roof, do your research extensively and ask the professionals, including the manufacturer to help you find the best dealer, right materials that come with a warranty and excellent performance record, and would also hold up for a longer duration.
