TPO Membrane Roofing

Everything You Need To Know About TPO Roofing

TPO roofs stand out in their bright nature that you might have noticed on the roof of many commercial buildings or facilities. They are very common in large facilities, and they also offer some of the greatest energy-saving benefits among all single-ply membrane roofing materails in the market.

TPO’s highly reflective nature makes it a favorite choice for many commercial roofing jobs. Its energy resistance and efficiency makes it one of the leading roofing materials in the industry.

What Is Single-Ply Membrane Roofing?

Single-Ply Membranes are materials made of synthetics or rubber, which protect your commercial building from the elements.

They are installed using chemicals, mechanical fastening methods, or through ballasting. Single-Ply Membrane Roofing is one of the most famous commercial roofing materials. It comes in different types based on budget and functions or features.

Single-ply membranes for commercial roofing are divided into two major categories; the Ethylene Propylene Diene Terpolymer (EPDM) and the Thermoplastic Polyolefin (TPO). These two materials have different chemical structures, installation processes, and energy efficiency levels.

What is TPO Roofing?

TPO, which stands for Thermoplastic Polyolefin, is a rapidly growing single-ply roofing membrane in the commercial roofing industry. TPO roofing systems comprise a single synthetic layer alongside reinforcing scrim mainly used to cover flat roofs.

TPO roofing membranes come in 10, 12, or 20 feet wide membranes that can be rolled up and transported. Due to its naturally reflective surface that protects against UV rays, TPO has been accepted in the industry as one of the best materials.

The National Roofing Contractors Association (NRCA) says that TPO currently holds about 40% of the shares in the commercial roofing market.

Why Choose TPO?

TPO is a great fit for many commercial buildings and facilities. Its membrane is the largest in the roofing industry. Its heat-welded seams and highly reflective material also make it one of the best roofing membranes to work with. SW Commercial Roofing has vast experience handling roofing contracts with TPO.

What are the Advantages of TPO?

  • – TPO can withstand changing weather conditions, UV rays and their accompanying heat, and higher temperatures.
  • – TPO membrane provides great energy efficiency over long periods, especially when installed in warm climates
  • – TPO membranes have warranties of about 30 years, they are up to 8 mils thick, and they have great long-term weathering features.
  •  – TPOs thicker membranes help it withstand UV rays and heat, and keeps facilities cool during the hotter seasons.
  •  – TPO membranes come in three basic colors and five special colors
  •  – TPO membranes can offer Underwriters Laboratories (UL) Class A fire resistance listings when fire retardant chemicals are added in the manufacturing phase.

TPO Roofing Installation Procedure

The facility manager prepares the substrate, either by removing the roof or cleaning it before the insulation is installed. There are several insulation options to consider and choose from. Let’s look at a few of them.

Expanded Polystyrene (EPS) – EPS is commonly used for floor and roof insulation. It has the highest R-value per dollar, and it works great for ground contact without retaining water over time.

Extruded Polystyrene (XPS) – XPS is a semi-permeable material with a rating of 1. It is identified by its pink, green, or blue color. XPS is cheaper than EPS but more expensive than Polyiso which we will look at below. It also falls between the other two insulations in the area of performance.

Polyisocyanurate (Polyiso) – Polyiso is the most famous insulation for roofing projects, and is more expensive than the other two. However, it makes up for the cost with a higher R-value rating. You can attach the TPO membrane to the cover board using mechanical fastening or a bonding adhesive. After rolling out the membrane, you then weld the seams in place with a hot-air gun.

How Much Does TPO Roofing Cost?

A regular 20,000 sq. foot commercial roof will need between $3.50 and $7.50 for each square foot for materials and work involved in installing the TPO membrane. Here are some factors to consider when seeking the best single-ply roofing prices.

  • Ease of access to the roof
  • Roof size
  • State of the existing roof
  • Roof penetration
  • Choice of membrane
  • Most-preferred Insulation option
