What is the life expectancy of a EPDM roof?
EPDM roof membranes remain stable over time and can have a life expectancy of over 50 years. ** Made from synthetic rubber, EPDM roofing membranes have two primary ingredients, ethylene and propylene, which are derived from oil and natural gas.
What color is EPDM roofing?
While TPO has a natural white color, EPDM results in a dark gray or black color for your roof. The darker color is not helpful in reflecting UV rays; it does retain heat for those in cooler weather.
What are common problems with EPDM roofs?
- punctures in, or damage to, the membrane.
- shrinkage.
- incorrectly installed or improper flashing.
- wrinkles extending into roof seams.
Is TPO more expensive than EPDM?
TPO roofing membranes are more expensive than EPDM. Regardless of which membrane you choose, it is better to spend more money and invest in a thicker membrane. Both EPDM and TPO roofs perform better and last longer if they are thicker.
Does EPDM come in white?

Can you put TPO over EPDM roof?
Yes. Recovering with TPO is a great option for a building with an aging EPDM roofing system. It’s easy. It’s far less costly and disruptive than a full tear-off.
What widths does EPDM roofing come in?
EPDM roofing membrane is available in a variety of widths ranging from 7.5 to fifty feet. According to Righteous Rubber Roofing, there are three thickness options: 45 Mil, 60 Mil, and 90 Mil. A Mil is a unit of measurement denoting a thousandth of an inch. A 45 Mil EPDM roofing membrane is about as thick as a dime.
What is difference between EPDM and nitrile rubber?
Although EPDM and nitrile are both synthetic rubbers, they are not the same material as EPDM is better resistant to outdoor environments than nitrile, and nitrile is better resistant to oils and greases than EPDM.
Is PVC or EPDM better?
Comprised of synthetic rubber, an ethylene propylene diene monomer (EPDM) roofing membrane offers superior weather resistance while remaining a cost-effective option. PVC, on the other hand, delivers exceptional seam strength; in fact, heat-welded PVC seams are stronger than the PVC roofing membrane itself.
Is EPDM waterproof?
EPDM is a synthetic rubber which is completely weather-resistant and UV-resistant. Thanks to its extreme elasticity of more than 500%, it is the most flexible single ply membranes for waterproofing flat roofs, buildings and facades.
What is the difference between EPDM and neoprene?
Share: EPDM and Neoprene are general purpose synthetic rubbers mostly differing in cost and a few key properties. While EPDM is cheaper, noise resistant, and a good electrical insulator, neoprene is a thermal insulator resistant to chemicals, oil, and fire.
Can you lay EPDM in the rain?
EPDM Membranes require the sustrate to be dry prior to installation. This is so the the adheshive & primers can effectively bond the rubber to roof deck. EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.
Can you glue EPDM to plywood?
EPDM should be bonded over 5/8″ plywood, 5/8″ OSB board, or polyisocyanurate board with a fiberglass backing.
What does EPDM stand for?
EPDM stands for ethylene propylene diene monomer, which is a bit of a mouthful, so it’s commonly shortened to EPDM or EPDM rubber. EPDM gets its name from the chemicals (monomers) that are mixed together in various proportions to form it. These are ethylene, propylene and diene.
Can you walk on EPDM rubber roofing?
Yes to an extent. EPDM is designed to take LIGHT foot traffic during installation and for occasional cleaning or maintenance. If you require more use than this, i.e. for a balcony then there are additional materials that can be laid over your EPDM for a more durable solution.
What is the life expectancy of a TPO roof?
A TPO roof membrane can last anywhere from 15 to 20 years. It is a single ply reflective roofing option, and it is typically adhered or mechanically attached. This membrane can be left exposed throughout its life.
How do you maintain a rubber roof?

- Sweep your flat roof to remove any debri. …
- Check your roof for blisters. …
- Maintain Surrounding Trees. …
- Clean Your Rubber Roof.
Is EPDM always black?
EPDM. This membrane is a mix of Ethylene, Propylene, and a bit of Diene Monomer (EPDM). Colors can vary from black to gray but it almost always has a smooth feel because it doesn’t contain surface granules.
How thick should EPDM roofing be?
EPDM membrane is manufactured in various thicknesses (. 045″ to . 090″ thick) and is available as a non-reinforced or reinforced sheet (depending upon application). Other thicknesses are also available for use in non-roofing applications as a special order.
What are the two types of EPDM?
White EPDM Roofing vs Black EPDM Roofing
EPDM membranes are available in black and white.
How can you tell the difference between EPDM and TPO?
The main difference between TPO and EPDM roofing is that the durability of EPDM is higher, while TPO has a better reflection of sunlight. In EPDM vs TPO comparison, the latter also has a wider variety of color options available.
Is PVC better than TPO?
While PVC offers better resistance to puncture and weathering, TPO (like PVC) is recyclable and environmentally friendly. Its reflective surface reduces UV radiation and helps with energy efficiency.
What is the white rubber roofing called?
GenTite White Rubber Roofing (EPDM – Ethylene Propylene Diene Monomer) is a high quality, commercial-grade rubber membrane that is resistant to weathering, tears, impacts, punctures and light foot traffic.
Does EPDM have to be glued down?
When you are fitting an EPDM roof, you need to make sure that it is glued down properly. During the membrane application process, you will need to apply two different types of adhesive. The first is a water-based adhesive. Use Permaroof deck adhesive for the best results.
Is EPDM a PVC?
EPDM is a synthetic rubber made from ethylene and propylene and has excellent ozone and weather resistant properties. PVC is a widely used thermoplastic elastomer with chemical and oil resistance, and good impact resistant properties. Both these polymers are used in weather resistant applications.
Which is cheaper EPDM or TPO?
Ballasted EPDM systems are relatively inexpensive when compared to others, however fully adhered or mechanical systems are slightly more expensive than TPO.
Why is EPDM black?
In addition to the oils and the polymers used to make an EPDM membrane, another ingredient is added to the mix to enhance UV resistance. In the case of a black membrane, carbon black is added, which converts UV rays into heat.
