Install a rubber roof the DIY way

Clean the area first

You may not realise it, but when it comes to applying a rubber roof, one of the worst things that you can do is to try to install it on a roof deck that is dirty and dusty. There are two reasons for this.

The first is that if you adhere the membrane to a dirty roof, you are likely to end up with a bumpy mess that you will want to do again. Secondly, the adhesive that is used in rubber roofing isn’t going to adhere reliably if the surface isn’t clean and clear of dust or debris.

Cleaning your roof need not be tricky, all you need to do is give it a good brush down with a soft household brush that should remove enough of the dust to create the ideal surface to work with. Also remove oil or grease spots.

Installing Rubber Roofing Yourself

Let your rubber roof rest before you install

Once you have cleaned the roof ready for the membrane to be applied, get out your brand-new roof and let it rest. When the membrane is transported, it can become wrinkled, it can also contract or expand during the shipping process too. By allowing it some time to rest, you will be able to apply a smooth and wrinkle free roof with ease.

Time to apply your glue

When you are fitting an EPDM roof, you need to make sure that it is glued down properly. During the membrane application process, you will need to apply two different types of adhesive. The first is a water-based adhesive. Use Permaroof deck adhesive for the best results.

To apply this, you need to fold back one half of the membrane, before applying the glue to the roof decking. Do this with a 9” roller, as this will make sure that the glue is evenly spread and it won’t have any lumps that will be visible underneath the membrane, once it has dried. Once the water-based adhesive has been applied, Use contact adhesive at the edges. This is much stronger than the water based adhesive and needs to be applied to the edges of the roof. The contact adhesive will dry much more quickly than the water-based adhesive and should be applied to the roof deck and the membrane too.

If you’ve purchased a flat roof kit, you will have everything you need in the right quantities.

If you’ve got the adhesive right, and the preparation from the start, rolling the membrane onto the roof deck is the easy part. Make sure it is laid evenly and double-check you don’t have air bubbles trapped underneath. You may worry that to install a rubber roof, you’re going to find it difficult, but in actual fact, it can be quite easy to do.

Think about the process, buy the right materials and make sure that you have everything that you need and in no time at all you will have a beautiful rubber roof, that you installed yourself.
