    EPDM Rubber Roofing FAQ's

EPDM roofing ?

Ethylene Propylene Diene Monomer, commonly referred to as EPDM, is a durable, long-lasting synthetic rubber roofing membrane that is used on flat and low-pitched roofs.

The rubber membrane is an incredibly versatile material that costs little to maintain and is easy to install.

An EPDM rubber roof can be installed onto a surface either fully adhered or mechanically attached. EPDM membranes can be joined using seam tape or with EPDM Primer.

The physical properties of the rubber membrane of an EPDM flat roof are why the roofing system is incredibly popular for UK homeowners and commercial buildings. A rubber roof is easy to install, repair and maintain.

The rubber membrane is tear-resistant and has outstanding abrasion resistance.

The rubber for an EPDM flat roof has many of the same physical features of natural rubber; however, this rubber membrane is designed to have weathering resistance, making it an ideal choice for a roof.

For the last 50 years, EPDM rubber roofs have been used globally. The rubber roof membrane offers a wealth of benefits including:

  • Heat and cold resistant.
  • Environmentally friendly / 100% recyclable.
  • Durable, resilient and long-lasting material.
  • Offered in a single, seamless sheet.
  • Rubber membrane is waterproof.
  • The EPDM roof is lightweight.
  • Incredibly low life-cycle maintenance cost.
  • Heat-free installation.

What Type of Rubber Membranes are there?

The EPDM rubber roofing membrane is designed to be incredibly economical and easy to apply. There is a range of EPDM rubber roofing systems that can be cut and measured to fit a surface.

With a life expectancy of 50 years, you can be assured that your roof will be protected for the future.

We continue to offer the ClassicBond EPDM for all our UK customers.

  • DuoPly is an EPDM that has been laminated to a polyester fleece layer for extra reinforcement.

This tougher rubber membrane is ideal for all roofs, balconies and high-spec projects. It's ideal for overlaying existing roof systems and for applications where a tougher membrane is needed.

  • Shed Rubber is designed to replace your current shed roofing such as felt.

We offer complete shed kits that can transform your shed roof today.

More On EPDM

What is EPDM?

Ethylene propylene diene monomer rubber is a type of synthetic rubber, otherwise known as EPDM, which is used across many types of installations. The rubber is an M-Class one, conforming to ASTM standard D-1418. The M class EPDM is made from ethylenepropylene, and a diene which enables crosslinking via sulphur vulcanisation.

The technical stuff

From a semi-crystalline material, EPDM has ethylene-type crystal structures, similar to ethylene and appearing at higher ethylene contents, meaning that they become essentially amorphous once these contents approach 50 wt%. 45-85% of EPDM propylene has been co-polymerised to reduce the formation of the typical crystallinity of polyethylene.

Why do we use it?

Rubbers with saturated polymer backbones, such as EPDM, generally have much better resistance to heat, light and ozone than unsaturated rubbers such as Neoprene.

Therefore, EPDM can be formulated to be resistant to temperatures as high as 150°C, and once properly formulated, can be used outside for years, or even decades, without degradation. EPDM is flexible, it has good low-temperature properties - as low as -40°C - depending on the formulation and the grade.

A more advanced form of EPDM roofing membrane has fleece on the back which makes the membrane much tougher and is used for waterproofing roofs

As with most rubbers, EPDM is almost always used compounded with fillers such as calcium carbonate and carbon black, with plasticisers like paraffinic oils, but only has useful rubber properties when crosslinked. Vulcanisation with sulphur is generally used for crosslinking, but it can also be done with peroxides, leading to better heat resistance, or with phenolic resins. High energy radiation, such as that from electron beams, is sometimes used for producing foams and wires and cables.

EPDM Properties

EPDM is compatible with polar substances, such as fireproof hydraulic fluids, hot and cold water, ketones and alkalis. It is incompatible with most hydrocarbons, such as oilskerosene,  gasoline, as well as halogenated solvents and natural gas, fuel oil, diesel fuel, coal, kerosene, and propane. EPDM has outstanding resistance to heatozonesteam and weather and it is often used as an electrical insulator.

Depending on the EPDM polymers available, it can be compounded to meet specific properties to a limit, before the curing and processing methods are employed. EPDMs are available in a range of molecular weights and at varying levels of third monomer, ethylene and oil content.

Common EDPM uses

EDPM is a malleable material and it can be used for multiple purposes, including:

  1. Vehicles. Frequently, car seals are the source of noise because of the movement of the door against the car body and then the resulting friction between the mating surface (glass or painted sheet metal) and EPDM rubber. By using speciality coatings that are applied at the time of manufacture of the weather seal, the noise can be alleviated. The coatings can also improve the chemical resistance of EPDM rubber. It is also used for door and window seals and sometimes bonnet and boot seals. Other uses in vehicles include the cooling system circuit hoses, thermostats, radiators, EGR coolers, heaters and oil coolers which are all connected with EDPM.
  2. EPDM is also used in cold-room doors like an insulator, or the face seals of industrial respirators in automotive paint spray environments. Such as glass-run channelsradiators, garden, and appliances such as hoses, pond linerswashers, and O-rings, plus geomembranes and electrical cable jointing.
  3. Other multiple miscellaneous uses; beltselectrical insulationvibratorssolar panel heat collectors, and speaker cone surrounds. Also rubber mechanical goods, plastic impact modification and thermoplastics.

Most importantly, this synthetic rubber membrane is a popular choice for flat roofs because of its durability and low maintenance costs.

Plus, just on the off-chance that you’re considering rainwater harvesting, this roofing membranewill not pollute the run-off rainwater.

Extra uses.

Coloured EPDM granules are often mixed with polyurethane binders to be sprayed or trowelled onto surfaces such as asphalt, concrete, concrete, interlocking brick, screenings and wood to create a soft, non-slip, porous safety surface for wet-deck areas and safety surfacing under playground equipment.
