Rob the Roofer: Is the Installation of EPDM Weather Dependent?


Here at PermaRoof UK, our award-winning sales and customer support teams are asked for advice about EPDM products every day. Because ‘Is the Installation of EPDM Weather Dependent?’ is a common question on the subject, we thought we’d ask Rob the Roofer, our resident EPDM expert, to explain.

Rob, is installing EPDM dependent on the weather?

It is dependent on the weather, primarily – rain. So, you do always have to be aware if rain is imminent. Always keep a lookout for that. You cannot lay EPDM while it is raining – it must be dry while you are installing the membrane. 

Temperatures are critical, particularly when we are using the water based adhesive to bond the membrane down to a timber deck. The correct temperatures for using the water based adhesive are plus five degrees and higher.

Other EPDM installation tips

EPDM is fast and straightforward to install for most typical domestic projects, such as re-roofing sheds, garages and flat roofed extensions. Here’s a few tips to guide you along the way. You can find further resources and guides to help you further in the downloads library here.

Measure the project area carefully.

Buy an EPDM roofing kit to simplify ordering: buy standard sized kits or build your own here.

Be aware that not all EPDM is the same: Find out how to make sure you're not buying a cheap replica in our blog post here.

Make sure you’ve got everything you need before you start: if you’re not buying an EPDM kit, ensure you’ve included the right quantities of materials to your order – sufficient membrane, adhesive, primer (if required), rollers (if you’re using primer or liquid adhesive), edge and gutter trim (if required), fixings and tools (see below).

Get your tools ready:

  • Medium soft household broom
  • Piece of chalk or crayon
  • Straight edge
  • Sharp scissors
  • Penny and seam roller for detailing

Watch the weather: Pick a clear day to install EPDM with no rain expected. Do not install if rain is due or temperatures are likely to fall below 5°C.

Prepare the EPDM: Lay the membrane out over the roof surface to rest for 30 minutes before installation.

Adhere to basic safety guidelines

Follow the installation guidelines: find step-by-step guides in our downloads library. We also have a wide range of video tutorials, produced by the training team and containing clear installation processes.
