tpo vs epdm roofing

There are many different types of roofing materials on the market today, and it can be difficult to decide which one is right for your situation.

In this article, we will compare TPO vs EPDM roofing to help you make an informed decision.

TPO Roofing System

TPO roofing is one of the most popular types of commercial roofing on the market today. TPO stands for thermoplastic polyolefin, and it is a single-ply membrane that is heat-welded together at the seams.

TPO roofing is available in white, gray, and black, and it reflects heat very well, which can help keep your building cooler in the summer.

TPO roofing is also very resistant to tears and punctures, and it can be installed over almost any type of substrate.

TPO roofing is a popular choice because it is energy efficient and very durable and can last up to 20 years with proper maintenance.

How to install a TPO roof?

There are several ways to install a TPO roof, but the most common method is to use mechanical fasteners and adhesives.

  1. First, the installer will apply a primer to the surface of the roof deck. This helps the fasteners and adhesives to bond properly.
  2. Next, they will attach the membrane to the roof deck using either fasteners or adhesives.
  3. Finally, they will seal all of the seams and flashings to create a watertight barrier.

How much is a TPO roof?

The cost of a TPO roof will vary depending on the size and complexity of your project. However, you can expect to pay between $1.90 and $3.50 per square foot for materials. 

EPDM Roofing System

EPDM roofing is a type of synthetic rubber roofing that is most commonly used on commercial and industrial buildings.

EPDM stands for ethylene propylene diene monomer, which is the main ingredient in this type of roofing. It is resistant to fire, wind, hail, and UV rays.

EPDM roofing is available in two different thicknesses, 45 and 60 mils. The 45-mil thickness is the most common and is suitable for most commercial applications.

The 60-mil thickness is typically used for industrial buildings or buildings in areas with severe weather conditions.

EPDM roofing system

EPDM roofing is installed by bonding the seams of the roofing material with an adhesive or by mechanically fastening it to the roof deck.

Once it is installed, EPDM roofing is very low maintenance and does not require regular inspection or repair.

If you are considering EPDM roofing for your commercial or industrial building, contact a roofing contractor to discuss your options.

They can help you choose the right thickness and type of EPDM roofing for your building and climate, and they can provide a free estimate for the cost of installation.

EPDM roofing is a great choice for someone who’s looking for an affordable option, but it can be less energy efficient than TPO roofing and may require more maintenance over the years.

How to install EPDM roofing?

  1. Clear the roof of any debris or obstacles.
  2. Measure the roof area to be covered and calculate the amount of EPDM roofing material needed.
  3. Cut the EPDM roofing material to size, allowing for an overlap of at least 2 inches (5 cm).
  4. Apply a layer of EPDM primer to the roof surface.
  5. Lay the EPDM roofing material in place and secure it with adhesive, nails, or screws.
  6. Seal the seams and edges of the EPDM roofing material with a compatible sealant.
  7. And allow the EPDM roofing material to cure for the amount of time specified by the manufacturer.

How much is an EPDM roof?

EPDM roofing is one of the most affordable types of roofing on the market, and you can expect to pay between $1.80 and $3.50 per square foot for materials.

Installation costs will vary depending on the size and complexity of your project, but you can expect to pay more.

TPO Roofing Vs. EPDM – Which one should you choose?

There are a few key factors you’ll want to consider when making your decision, including:

1. The climate in your area – TPO is better suited for hot climates because it repels sunlight, while EPDM retains heat in colder temperatures.

2. The location of the roof – TPO is more lightweight and therefore ideal for roofing that is located at a higher altitude. EPDM, on the other hand, is better suited for roofs that are closer to the ground.

3. The choices of color – TPO often comes in white, grey, tan, and a few other colors. While EPDM is more commonly sold in black color.

4. Your budget – TPO tends to be a tad bit more expensive than EPDM

Which is Better? TPO or EPDM

There is no easy answer when it comes to TPO versus EPDM roofing. Both have their own unique set of benefits and drawbacks that you’ll need to consider before making a decision.

If you’re still not sure which is right for you, contact a roofing contractor in your area for more information and a free estimate. They can help you weigh the pros and cons of each type of roofing and make the best decision for your home or business.
