Make sure your roof is clean and well-prepared

The first thing that you need to do when it comes to installing an EPDM membrane is to make sure that the roof surface that you are applying it to is completely clean and clear.

You need to remove any dust and dirt, as well as any loose or oily materials too.

Not only will these stop the membrane from adhering to the roof surface properly, but you can also find that it doesn’t last as long as it could if the surface was properly cleaned first.

Relax the membrane and allow it to sit

An EPDM membrane is going to have been sitting in a particular position for some time during packing and delivery, which means that it might not be in the right condition to install straightaway.

It is important that you give your membrane a chance to rest before you begin the installation process. This should be around the 30 minute mark, over which time you will find that the EPDM has settled, and it is in the ideal condition.

Make sure that it is the right size

This is also a good time to make sure that the membrane is the right size for your roof.

If you have used a calculation tool then you should find that the membrane fits with very little waste, however, there is still a chance that you are going to need to trim some of it off in order to get it to the right size.

Apply adhesive

In order to make sure that the membrane stays in place, you are going to need to apply adhesive to the roof.

There are two types of adhesive that you are going to need to use in order to make sure that your roof stays in place.

The first is a water based one that covers the entire surface of the roof.

The second is a contact-based adhesive that is stronger and is used to seal down the edges.

Adhering the EPDM

It is important to make sure you firmly adhere the EDPM membrane properly to the roof deck once the adhesive has become tacky.

Use a wide-span domestic broom with soft bristles to press down the membrane, the roller to push out any bubbles, and the penny roller into the corners and edges.

As you can see there is plenty to think about when you are installing an EPDM membrane in your home or garden. However, much like many DIY projects, if you plan, prepare and put your mind to it, all should be relatively easy for you.
