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.

Can EPDM withstand hard impacts from outside conditions? Such as branches falling on it or a bird pecking on it?

Along with a life expectancy of 50 years and beyond, EPDM rubber can stand up to quite some force from outside elements, in our video below we explore what different objects falling on the rubber will do to it and how much damage it takes to actually penetrate the membrane! 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. There are a few reasons why this can happen, the Contact Adhesive could have been applied too thick, or if it has not been allowed enough time to properly tack-off. Luckily we can share a few tips to help avoid this potential problem, check our video for an in-depth explanation.

How should I store my rubber roof kit?

If its going to be a few weeks before you fit the roof, we would suggest unrolling the membrane and re-rolling it longways, this will help prevent any creases forming. The adhesives and trims need to be stored indoors before fitting, rather than leaving them outside, as they can be affected by temperature fluctuations. Check out our video below for a full explanation from Sam! 

What Products Will I Receive In My Rubber Roof Kit?

We sell a wide variety of EPDM rubber flat roofing kits to our customers and try to provide the widest possible selection, with options for many different types of flat roofs available from Orangery Roofs to Garden Rooms. Check our video below for a full breakdown of what to expect in your kit! (The information about the contents of your kit can be found on the product page on our website.)

How Long Does it Take to Install a Rubber Roof on a Garden Building?

Fitting a rubber roof to a garden building can be a very quick job if you have some basic knowledge about the preparation and correct steps to take. It can take a professional less than 1.5 hours to fit a garden room roof!

Which Timber Boards Should I Use For My New Rubber Roof?

Choosing the right boards for your job can be daunting with many different options available to use for flat roof decking, however some are much more highly recommended than others, in our video below, Sam covers the key differences between the most commonly used boards, OSB3 and S-Grade Plywood.

Does it have to be dry for EPDM roofing to be laid?

Yes, EPDM Membranes require the substrate to be dry prior to installation. This is so the the adhesive & primers can effectively bond the rubber to roof deck. EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.

Is Classicbond EPDM BBA Certified?

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 seak 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.
