If you don't see the answer to your question below then feel free to contact us.

  • Can ClassicBond one-piece EPDM sheets be joined?

    Obviously there is a limit to the size any one-piece sheet can be. As-well-as size considerations there is also the weight issue. There are also occasions when the roof shape makes it impossible to use one piece.

    Fortunately the joining system is a very simple but effective solution. Typically a jointing tape is used to provide a strong watertight seal; over time it becomes as strong as the membrane itself. Contact adhesive or decking adhesive cannot be used to form a watertight join in the ClassicBond one-piece EPDM.

  • Can ClassicBond one-piece EPDM be laid over existing roof covering?

    In theory ClassicBond one-piece EPDM membrane can be laid over existing fibreglass, fibrous cement boards, felt, bitumen and steel roof cladding. However in practice it is not always a good idea, requiring the use of specialist adhesives and or mechanical fixing. Use our Which EPDM is right for the job? tool to see which EPDM system is best for you and, if unsure please feel free to contact us. for advice.

  • Is the ClassicBond one-piece EPDM membrane guaranteed?

    Unless otherwise specified by us, ClassicBond one-piece EPDM membrane is guaranteed for 10 years. Although the expected lifespan of a ClassicBond one-piece EPDM membrane is in excess of 40 years.

  • Do I need any special tools?

    As ClassicBond one-piece EPDM is a cold application system no special tools are required. Basic hand tools like scissors, paint rollers and disposable paintbrushes are all that is required.

  • Can I walk on the ClassicBond one-piece EPDM?

    The ClassicBond one-piece EPDM membrane supplied can be walked on both during and after installation. However please note that ClassicBond one-piece EPDM is designed to take LIGHT foot traffic for occasional cleaning or maintenance. Avoid studded boots and shoes. If ladders are going to be used, ladder protection mattsshould be placed under the feet to avoid any damage to the roof membrane.

  • What colours are available?

    We are only stock ClassicBond one-piece EPDM membrane in black.

  • What size sheet do I need?

    On a normal extension it is advisable to measure the roof area and then add 300mm to the length and width - i.e. roof size: 4m x 2m = sheet size required: 4.3m x 2.3m. Where a flat roof runs into a tiled/slate roof it is advisable to add 400mm - i.e. flat roof area 4m x 2m with 4m edge abutting tiled roof = sheet size required: 4.4m x 2.3m.
