The ideal length of overhang is around 150mm. We allow an additional 300mm of EPDM in our standard garage roof kits to ensure an even overhang on all sides. Please add 300mm to both width and length measurements when ordering enter-your-own-size kits.

Why EPDM rubber roof kits?2022-12-12T13:10:07+00:00

EPDM has the longevity and performance you need for modern flat roof renovations, and it is fast-becoming the material of choice for specialist flat roofers all over the world. With a wide range of benefits, this high performing synthetic rubber membrane is the ideal, sustainable alternative to felt and other traditional materials that environmentally-conscious homeowners and tradespeople have been looking for.

How long does EPDM last?

With a 50-year service life expectancy, EPDM outperforms traditional flat roofing materials by far. RubberCover EPDM membranes have long warranties and when fitted by a PermaRoof Registered Installer, these can be extended by up to 30 years. We’re so confident in EPDM that all our shed roof kits contain a lifetime membrane guarantee.
