Manufactured by the worlds leading EPDM manufacturer, ClassicBond roof systems offer economical, easy installation and require no special tools or installation equipment, making it the perfect choice for both refurbishments and new build projects. The ClassicBond EPDM flat roofing system has been awarded the British Board of Agrément certificate, No. 19/5670, with a service life in excess of 35 years.
ClassicBond EPDM membranes offer high resistance to ozone, weathering and abrasion, including extremes of temperature. Tests have proven that roofs perform like new after three decades of exposure. ClassicBond membranes are also environmentally friendly, CE approved and hold the highest European fire ratings. Suitable for residential, commercial and green roof applications, ClassicBond EPDM roofing membranes are the ideal choice for both residential and commercial projects. In comparison to conventional DIY flat roof systems, the ClassicBond roof system is significantly more affordable and simpler to install, saving you both time and money.
ClassicBond is the best EPDM rubber roof covering for both large and small flat roofs. It is BBA certified and preferred by roofing experts and is noticeably more malleable and slate grey in colour.
Depending on the size you order, your EPDM may have manufacturing seams or joins, but it will still be provided in one piece. The joins are machine-processed to be strong and long-lasting, and are often one of the strongest pieces of the membrane. It also means you don't have to do any joins on-site.
Please Note: This product is made to order/custom made and cannot be re-sold therefore is non-returnable.
ClassicBond FAQs
What is The Life Expectancy of EPDM Rubber Roofs?
EPDM Rubber roofs have a 50 year life expectancy.
Is There A Right Side Up When Installing ClassicBond EPDM Membranes?
Classicbond EPDM membranes are identical on both sides so there is no right or wrong side when installing this product. It is important to bear in mind that sometimes there may be a small amount of manufacturer writing printed on one side of the rubber membrane; if this is the case we recommend installing this side down onto the deck so that the clear side is only visible.
Will my membrane be in one piece? And will it have joins?
More often than not, your EPDM membrane will be in one piece but have manufacturing joins at certain intervals. These are unavoidable but necessary to provide it in one piece, meaning no on-site joins are required.
The joins are done with a process called vulcanisation, which is done with heat, pressure and seam tape. This provides a good join that is strong as it's effectively two layers of EPDM in one place.
Does It Have To Be Dry For EPDM Roofing To Be Laid?
EPDM membranes require the substrate to be dry prior to installation so that the adhesive & primers can effectively bond the rubber to the roof deck. EPDM products will not adhere to wet or damp surfaces. It is important to bear in mind that trapped moisture within the deck may vaporize and negatively affect the performance of the membrane.
Can EPDM Withstand Hard Impacts From Outside Conditions?
Along with a life expectancy of 50 years and beyond, EPDM rubber can stand up to quite some force from outside elements.
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.
Is it safe to walk on an EPDM rubber roof?
EPDM rubber membrane is an extremely tough material that will easily handle light foot traffic, such as when it's being installed. However, it is important to make sure no sharp objects are introduced onto the membrane from boots or tools.
Which Thickness of rubber roofing membrane should I buy?
Both the 1.2mm and 1.5mm EPDM rubber membranes are perfect for residential and commercial projects alike. 1.2mm membrane is a trusted product by our roofing customers and our most popular item for a good reason. 1.5mm membrane tends to lay a little easier due to the thickness and can also provide a smoother looking finished flat roof. We would recommend 1.5mm if there is going to be anything overlayed on top of the rubber like decking, screed and tiles or even a green roof.
Can EPDM Sheets Be Joined?
Yes. This is useful for roofs larger than the sheet size, or if it's easier to install in smaller sections.
Are The EPDM Membranes Guaranteed?
A 20 year guarantee is available to all certified installers who have attended a training course.
Does EPDM rubber have a factory join?
Yes it has a galvanised factory join, which has no detriment to the integrity of the membrane or join.
Can I Install Tiles Or Slabs Onto An EPDM Rubber Roof?
Yes, slabs or tiles can be installed on top of an EPDM flat roof.
Is The ClassicBond Membrane Available In Different Colours?
No, the membrane is only available in slate grey.
Is ClassicBond EPDM BBA Certified?
Yes, ClassicBond membrane holds the BBA certificate, No. 11/4853 (issued to Flex-R Ltd). It also holds fire ratings for each of the thicknesses available.
Do I need any special tools for my EPDM roof?
A 9" roller set, mini roller and brush for applying the adhesive, and scissors or a blade to trim any excess rubber. A seam roller and a penny roller are also useful.
Can I install a different substrate like cement screed or a green roof on top of a EPDM rubber membrane?
Yes, this is an option with the 1.5mm EPDM rubber. However, it's recommended to use something like a Geotextile fleece laid on top, rather than placing anything directly on the rubber.
How much overhang do I need on the membrane?
As a general rule, around 300mm on the length and width, which will give you 150mm tolerance on all sides.
What temperatures can EPDM rubber withstand?
EPDM rubber can withstand temperature ranges from -40ºC to +120ºC.
How heavy is the membrane?
To work out the weight of rubber, multiply the total square metre by 1.5 for a 1.2mm membrane and multiply by 2.0 for 1.5mm membrane.
Is there a minimum pitch required to install EPDM rubber?
The minimum pitch is 5 degrees and the maximum is 15 degrees. If the pitch is higher than 15 degrees, the EPDM will need to be laid with contact adhesive only.
What surfaces can EPDM rubber be bonded to?
Please note: Upstands and perimeter are always bonded with contact bonding adhesive or spray contact.
What kind of temperature can EPDM rubber be installed in?
Anything above 4 degrees will be OK.
My roof has a small hole which is causing a leak, how easy is it to repair this?
One of the benefits of EPDM is that it can be repaired very quickly and easily. A small hole or rip can be sealed with a patch repair kit.
Can EPDM rubber be painted?
Yes, but using acrylic based paint only.

What's is the life expectancy of Classicbond Pro?
It has a life expectancy of 50 years.
Does Classicbond Pro possess thermal properties?
The fleece is there to allow the membrane to be laid directly onto different substrates like felt, not for any thermal properties.
Does Classicbond Pro possess U Value?
The U Value of the Classicbond Pro is not something that is tested because it doesn't serve that purpose.
How do you join other parts of the Classicbond Pro where this no 3 inch tape applied?
You will need to use 6 inch tape to run along the whole ends where there isn't 3 inch tape pre-installed. You will also require 9 inch tape corner patches to seal any cross junctions / butt ends.
