What is The Life Expectancy of EPDM Rubber Roofs?

EPDM Rubber roofs have a 50 year life expectancy.

EPDM has been in commercial use since the 1960s. And many of those roofs are still around today. 

My roof has a small hole which is causing a leak, how easy is it to repair this?

One of the most evident benefits of EPDM rubber roofing is that it can be repaired very quickly and easily, allowing you to catch a problem before it turns into something much bigger! Supplied as a 6 inch strip, any small hole or rip can be sealed effectively with our repair patch kits. This easy-to-use patch, primer and brush combination will ensure you can safely patch any minor damage to the roof.

Prepare to be surprised!

Why Have Bubbles Appeared On The Edge Of My Newly Laid EPDM Rubber Roof?

Occasionally, bubbles and blisters can appear around the perimeter of the EPDM rubber roof just after it's been fitted.

Luckily we can share a few tips to help avoid this potential problem, check our video for an in-depth explanation.

Yes. ClassicBond EPDM holds the British Board of Agrément certificate, No. 11/4853, issued to Flex-R Ltd. The BBA carries out assessment, testing, approval and certification of products and systems for the construction industry against national requirements, internationally recognized standards or other relevant technical specifications, reviewed and reissued every 3 years.

Fire Ratings

The ClassicBond system is also fire rated, the 1.2mm EPDM has a fire rating of EXT.F.AB and the 1.5mm EPDM membrane is fire rated to EXT.F.AA. Fire rating is carried out on a variety of deck surfaces and it is important to seek the certificate that relates most accurately to your roof structure.

What Temperatures Can A Rubber Roof Be Installed In?

We recommentd a minimum tempereture of 5 degrees C for EPDM installation. This is due the the WBA adhesive being water based and lower temperetures may cause the adhesive to freeze over and fail.
