Rubber Roof Coverings For Flat Roofs

Welcome to Daniel’s Roof and our excellent guide to rubber roof coverings for flat roofs.

Epdm stands for Ethylene Propylene Diene Monomer and is a type of synthetic rubber based roof covering that is used instead of more traditional materials such as asphalt, torch-on felt and fibre glass. For smaller projects the sheets can be purchased as a single large roll which is then installed without any joints. For larger projects standard rolls can be specified and joints/overlaps sealed with a chemical bonding agent.

Unlike bitumen and asphalt based products, there is no gas or heat required to lay these rubber sheets. This means that the fire risk of the project is almost non-existent ensuring lower insurance premiums for the contractor and peace of mind for the home-owner.

Below you can find more information about these rubber products.

Benefits of Using Rubber

Rubber for flat roof coveringThere are many benefits to rubber roof coatings, these include:

  • No scrap value – will deter thieves, unlike lead.
  • Unlike bitumen it is very resistant to UV rays and weathering.
  • Rubber characteristics prevent cracks from thermal movement.
  • Flexible even in low temperatures.
  • Fully wind resistant.
  • No heat is applied during installation.
  • Can be sealed to timber, brick and metal
  • Backed by longer guarantees

All in One Sheets

All in one roof sheets are best used on smaller projects. The sheet is manufactured either to your specifications or to a standard large size, it is then cut down to size on site and installed with the relevant roof trims and finishes. The sheet should be applied straight to the timber decking and not to any existing oil based felt which should first be fully removed.

Bonded Sheet Coverings

For most installations standard sized rolls should be installed and bonded to each other on the overlaps in accordance with the manufacturers guidelines and using the suggested resin bonder. Extra care should be taken at the overlaps as these sheets do have a high degree of thermal movement and stress on the overlaps. The bonding agent is fully capable of coping with this movement over the life expectancy of the material but only if the strict installation guidelines are adhered to.
