There are several factors that determine the suitability of a single-ply roofing system, including its aesthetics, insurance requirements, building heights, wind exposure, and energy efficiency. When considering the single-ply roofing system, it is important to select a professional who can install it properly. Read on to learn more about the pros and cons of single-ply roofing systems. Read on for tips and advice on choosing the right material for your needs.

EPDM

The benefits of EPDM single ply roofing are numerous. EPDM single ply roofing is environmentally friendly, comes in two colors (black and white), is flexible, fire resistant, and can last up to 30 years with proper maintenance. It can withstand small hail and other windblown debris without being damaged, and is highly resistant to UV rays. The EPDM roofing has a proven track record and is highly regarded for its longevity.

The EPDM membrane is a highly durable, seamless material that is a good choice for low-slope applications and residential flat roofs. It also has excellent fire resistance and is highly reflective. It’s easy to install and maintain. EPDM single ply roofing membranes offer superior energy efficiency and reduce environmental impact. Firestone Rubber Cover EPDM Roofing System checks all the boxes, and provides the best of both worlds for your building.

TPO

While TPO roofing is durable, the main drawbacks of TPO are its size and durability. Due to its low polymer content, it does not have the same strength and durability as other commercial roofing systems. Hence, it is difficult to purchase such a product in large sheets and will most likely result in copious seams. These seams are harmful to the durability of the roof, because the more they are, the more points of weakness it has.

One benefit of single-ply membrane is that it doesn’t rely on a single insulation solution and gives the customer more choices in choosing the correct level of insulation for their home. Another benefit of single-ply roofing is that it is fire resistant and can achieve Underwriters Laboratories (UL) Class A fire resistance listings. TPO roofing is highly reflective and is white in color, while EPDM is considered a “Black Roof” due to its natural dark color.

Polyisocyanurate

A common failure mode of polyisocyanurate single ply roof systems is insulation failure. The most common insulation material is polyisocyanurate, which is characterized by a high R-value per inch. This material is compatible with common roofing adhesives and is available in 20 and 25 psi compressive strengths. Some of the most common insulation failure modes are described below:

The R-Value is an important measure of insulation’s thermal performance. The higher the R-Value, the better. The Roofing Industry Alliance for Progress (RiAP) and the National Roofing Contractors Association have a free online calculator that you can use to calculate your building’s R-values. The program measures thermal performance and energy efficiency, and allows you to use the information you get from the calculator to find the most energy-efficient roof for your home.

For many years, polyisocyanurate roofing has been the insulating material of choice. It offers the highest R-value per inch of thickness, and is available in several board sizes. It is fabricated to ASTM C1289 Type II, Grade 2 and UL 94-C-29. It is also lightweight, requiring only eight fasteners per 4' x 8' board.

PVC

The LCI modeling structure applied in this study was based on the PVC single ply roofing membranes process. The input/output structure included raw materials, intermediate products, ancillary materials, packaging materials, emissions to air, and solid and liquid waste disposal. The models were cross-checked to verify the plausibility of mass flows. The modeling team conducted energy and mass balances at selected process levels and at the facility level.

TPO and PVC single ply roofing membranes are both extremely durable, and can last as long as 30 years with proper maintenance. Elastomeric roof coatings are available to recondition single ply roofing. Heidler Roofing offers single ply roofing repair services and installation. We also provide elastomeric roof coatings for both types of materials. To learn more about PVC single ply roofing, please visit our website.
