Membrane roofing has been a top pick for big buildings for a long time. But now, some houses in certain places are using it too. One of the main types of membrane roofing for homes is called EPDM. But what exactly is EPDM roofing? And what should you keep in mind about it?

What Does EPDM Stand for?

EPDM, which stands for ethylene propylene diene monomer, is a remarkably versatile roofing material. It’s a tough, man-made, rubbery substance that’s not just for commercial buildings. It’s also a popular choice for homeowners, whether they’re looking to cover a carport or a patio roof.

Types of EPDM

EPDM comes in black or ‘white.’ The ‘white’ type is actually an extra layer added to the regular EPDM. You can get EPDM in different widths, from 7.5 feet to 50 feet, and it comes in different thicknesses, like 45 mils, 60 mils, 75 mils, and 90 mils.
EPDM has several layers: the rubbery bottom layer, a fire-resistant layer, another reinforced with fabric for extra strength, and finally, an optional white layer that reflects sunlight.

Advantages of EPDM Roofing

The following are some major benefits of EPDM roofing:

  • Quick Installation: EPDM is easy to install because it comes in large sheets or rolls, typically 10 feet wide and 100 feet long. Unlike asphalt shingles, which are small and require individual placement, EPDM can cover a larger area more quickly.
  • Hail and Ozone Resistance: EPDM is made of rubber, so hailstones bounce off it. Thicker membranes, like 75 or 90 miles, are better for areas prone to hail. EPDM is also resistant to ozone up to 100ºF.
  • Energy Efficiency: EPDM is suitable for both hot and cold regions. Black EPDM absorbs heat, making it ideal for colder climates, while white EPDM reflects heat, reducing cooling costs in warmer areas.

Disadvantages of EPDM Roofing

EPDM roofing has some drawbacks to consider:

  • Not Suitable for DIY: While it might seem easy to install, it’s best to leave EPDM roofing to the professionals to avoid installation mistakes that could lead to roof failure.
  • Appearance: EPDM roofs are functional but not aesthetically pleasing, especially without added ballast. They typically appear as large sheets of black or white rubber.
  • Prone to Punctures: EPDM can puncture easily, especially with thinner membranes. However, thicker membranes or ballasted roofs offer better protection against punctures.
  • Poor Petroleum Resistance: EPDM is not resistant to petroleum-based products like oil and grease, which can cause it to break down over time.

What Is EPDM Roofing Price?

It’s hard to give an exact price for EPDM roofing because it depends on many factors. Generally, smaller projects cost around $14.00-$17.00 per square foot, while larger ones are about $12.00 per square foot.

Two main factors affect the price range. Firstly, the type of insulation used beneath the EPDM membrane impacts the cost. Thicker insulation is more expensive. Secondly, the size of the roof matters. Smaller projects cost more per square foot, while larger ones are cheaper.
