Some of the main advantages of EPDM are its outstanding resistance to deterioration from heat, ozone and weather. Compared to other systems used for similar purposes, EPDM performs especially well in cold weather.
What are common problems with EPDM roofs?
Three most common problems with Rubber Roofs is improper installation, shrinkage and the seams. While the rubber roofs are known to be durable, they also need maintained. EPDM roofs are fully adhered or as many call it glued down. The system is not attached mechanically.

RubberCover EPDM membranes offer unmatched resistance to UV radiation, ozone, alkaline rains and high or low temperatures. Recent studies show that the membrane has a life expectancy of more than 50 years, even when exposed to sunlight.
Will bubbles in EPDM go away?
Vapour from Contact Bonding Adhesive If the rubber is bonded prior to the adhesive drying then bubbles will appear under the membrane caused by the trapped vapour from the adhesive. These bubbles are often not severe and will disappear over a relatively short period of time as the EPDM membrane is partially breathable.
Can you lay EPDM in the rain?
EPDM Membranes require the sustrate to be dry prior to installation. … EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.
Is a rubber roof better than shingles?
Rubber shingles or rolls are much stronger and less likely to crack during extreme weather conditions than asphalt roofing. They are especially beneficial for flat or low-pitch roofs that traditional shingles have trouble effectively protecting due to the lack of gravitational pull.How long does a rubber roof last on a house?
How Long Do Rubber Roofs Last? Rubber roofing, when installed professionally, can last 25 years or more. TPO and EPDM roof systems have similar lifespans of 20 to 25 years. High-quality TPO roofing that is reinforced with fiberglass can last even longer.
Do gaskets have a shelf life?The sheet manufacturers give recommendations about their maximum shelf-life, typically around 2-5 years. Gaskets are one of the most critical components in a piping system. To give them a chance to work the way they were designed to, they need to be stored in a way that minimizes deterioration or damage.

Is EPDM synthetic rubber?
EPDM rubber is a type of synthetic rubber. It is extremely durable and flexible and therefore has a wide range of applications, including in vehicles (where it is used for window and door seals, as well as cooling system hoses), cold-rooms, non-slip coatings for decks and playgrounds and many others besides.
What is the best material to use on a flat roof?
PVC roofing Polyvinyl chloride (PVC) roofing membranes have been heralded as one of the best flat roofing materials in the single-ply roofing industry. The material is made from processed petroleum or a natural gas and salt mixture.
How do you maintain EPDM roofing?
Regular cleaning is required to maintain the EPDM surface, and consistent washes ensure resistance from heat cracking. When conducting routine rubber roofing cleans and check-ups, sweep away any excess leaves, sticks or material resting upon the rooftop.
How do I know if my rubber roof is bad?
Rubber roofing Looks wrinkled and not tight When wrinkles or ripples appear in the rubber it could indicate that moisture has entered under the rubber membrane and deteriorated the adhesive that glues the rubber to the insulation board. The rubber wrinkles as it is no longer glued down in that spot.
Can you walk on a EPDM roof?
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.
Is EPDM breathable?
EPDM – Brilliantly robust yet highly flexible, EPDM is a rubber-like material that is ideal for roofs with uneven surfaces. It is a breathable material, but also impermeable which means it allows moisture and heat to escape from the roof space without letting moisture, smoke and vapours can enter it.
How cold can you install EPDM?
FullForce EPDM and TPO SA may be installed when ambient and substrate temperatures exceed 20 °F (-7 °C).
What temperature can EPDM roofing be installed?
EPDM adhesive is very thick and hard to work with even at high temperatures. Manufacturers recommend the temperature be above 45° F (7° Celsius) for installation. This recommended temperature is not very practical unless a warm storage area is available to keep the adhesive warm until the moment it is used.
How long does a Firestone EPDM roof last?
Studies show a life expectancy for EPDM membranes of more than 50 years, even when exposed to sunlight. On top of its exceptional service-life, the membrane is easy to repair, even several decades after its installation.
Can you repair EPDM?
Repairing Punctures in or Damage to the EPDM Membrane However, one of the main advantages to EPDM is that it can be very easily repaired using a patch. There are also puncture-resistant single-ply membranes available (such as RESITRIX®).
What causes EPDM to swell?
EPDM is a hydrocarbon polymer, which swells excessively in hydrocarbon fluids such as mineral oils and hydrocarbon fuels, because of lack of polar groups in the polymer chain. An example of its swelling behavior is presented in Table 1.
Which is better EPDM or TPO?
EPDM roofs are the most economical choice for single ply roofing membranes. 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.
How much does an EPDM roof cost?
For installation, the EPDM roofing cost per square foot will normally range between $3.25 and $14.75. The average price is about $4.50 and $5.50 per square foot. That being said, you can expect to pay between $6,000 and $18,000 for a full roof.
