Are you considering installing a new roof? There are a ton of options out there, such as asphalt shingles, metal roofing, and clay tile. It can be difficult to choose between them all.
An increasing number of builders are turning to white membrane roofing, however. In Illinois, the mayor has implemented grant programs to encourage building owners to install new white roofs. It’s said that they can save money and improve the environment.
So what exactly is white membrane roofing and how beneficial are they?
What is a TPO Roof?
A TPO roof is one of the two main options for white membrane roofing. TPO, or Thermoplastic Polyolefin, is single-play and made up of a layer of synthetics and reinforcing scrim. They cost about $5 per square foot for both materials and labor.
TPO chemically adheres to insulation on your roof and the seams are fused with a hot air gun. They’re available in white, gray, tan, and other specialty colors.
This type of white membrane roofing system has only been used for the past couple of decades, and it’s typically meant to last up to twenty years.
What Is an EPDM Roof?
EPDM, or Ethylene Propylene Diene Monomer, is a single-ply membrane-like TPO. The main difference is that it’s made up of a synthetic rubber compound, providing more flexibility.
An EPDM roof coating costs about the same as TPO, but there are some important differences to consider.
First of all, EPDM is older than TPO and doesn’t reflect sunlight the same way. It’s mechanically attached and primarily comes in black or white.
Since an EPDM roof is applied with seam tape and can be ballasted, it requires no electricity to install. If you’re interested in learning more about the two types, you can contact Ryan Holmes Contracting, Inc.
Pros and Cons of a White Membrane Roofing System
One of the main benefits of white membrane roofing is that it can reflect or absorb sunlight depending on the type you get. TPO reflects heat, which helps to keep your home cool. EPDM absorbs heat, which can help keep your house warmer in the winter months.
You can apply roof membranes to existing surfaces, which helps increase your existing roof’s lifespan. It’s also resistant to roof leaks and UV deterioration.
The main drawback of a roof coating is that they tend to work best with flat roofs. You may also experience problems cooling your home if you apply the wrong type for your area.
Getting the Most Out of Your Roof
If you’re redoing your home’s roof, you want something that’ll last long without breaking the bank. White membrane roofing may be the right choice due to how durable it is. It can also help cool the inside of your home.
