Rubber Roofing offers the largest range of EPDM Roofing Systems

Rubber Roofing Direct is the UK’s leading EPDM roofing supplies

Our EPDM roofing systems are perfect for a range of garage, shed and other flat roofs. EPDM is fast replacing older traditional felt roofing materials as the go-to choice for roofers. 

Sold in convenient kits it has become a popular roofing material for repairing and replacing both flat roofs and dormer windows.

We offer a range of dependable EPDM roofing systems that are compromised of rubber membranes and other roofing supplies. 

There are alternatives to compare, such as PVC and Neoprene, however, EPDM rubber (Ethylene Propylene Diene Monomer) is proving the longest-lasting due to its water resistance qualities.

We have the largest supply of rubber roofing systems.

They’re becoming increasingly popular because of the number of benefits they offer to UK homeowners. These include:

  • Fast, Easy and Simple Installation – No Specialist Tools Needed
  • Resistant to Moss, Algae and UV rays
  • Extremely Weather Resistant and Environmentally Friendly
  • Proven Life Expectancy of 50 Years
  • Environmentally friendly, made from recycled rubber

EPDM rubber roofing systems are extremely cost-effective and require little to no maintenance. As well as expert advice on how to installation, we also offer a buying guide for quantities and prices.

Rubber Roofing Direct provide a range of EPDM roof kits and shed kits that contain rubber membranes in different sizes, instructions and the required adhesives needed for installation.

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 ethylene, propylene, 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 oils, kerosene,  gasoline, as well as halogenated solvents and natural gas, fuel oil, diesel fuel, coal, kerosene, and propane. EPDM has outstanding resistance to heat, ozone, steam 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:

  • 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.
  • 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 channels, radiators, garden, and appliances such as hoses, pond liners, washers, and O-rings, plus geomembranes and electrical cable jointing.
  • Other multiple miscellaneous uses; belts, electrical insulation, vibrators, solar 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.
