Can you install EPDM in the rain?
No, you should wait for a dry day to install EPDM as you cannot apply the adhesive or afford to trap moisture between membrane and roof deck.
Which Substrates Can EPDM be Adhered to?
EPDM can be adhered to all types of timber roof substrates and onto OSB or plywood for the best results. It is typically adhered to wood roof decks using a water-based adhesive. It can be adhered to other surfaces such as a tissue-faced insulation board using a contact bonding adhesive.
Does EPDM Require Special Tools for Installation?
The tools needed to install EPDM are as follows: Rollers – to apply the adhesive to the deck Soft brush or broom – to ensure 100% adhesion with no air pockets Penny roller and 50mm silicone seam roller – to dress in the details and any seams
Why do bubbles and wrinkles form after membrane installation?
Bubbles and wrinkles in EPDM membrane can be due to the application of either not enough adhesive or too much in certain places. Blistering can also occur if temperatures exceed the mid-20s during installation. This causes condensation on the membrane underside, which can prevent a full bond.
Can I install EPDM over the existing roof covering?
It is recommended that all existing roof covering is stripped back to the deck or substrate before installing EPDM. Suitable for installation over a range of substrates, use water-based adhesives for timber and bonding adhesive for other materials, such as concrete.

However, if EPDM does need to be joined, it is made straightforward with the use of EPDM seam tapes. There are two ways of joining EPDM
