Dormer Rubber Roof Kits

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 vaporise and negatively affect the performance of the membrane. 

If you would like more tips on when to install your EPDM roofing, check out the video below.

We sell a wide variety of EPDM rubber flat roofing kits to our customers and try to provide the widest possible selection, with options for many different types of flat roofs available from Orangery Roofs to Garden Rooms. Check our video below for a full breakdown of what to expect in your kit! (The information about the contents of your kit can be found on the product page on our website.)

For the most part, each section of the installation is easy. Gluing the membrane down with both adhesives is very straightforward and securing the trims and clips to the perimeter is as well. Watch our video for a detailed step by step breakdown so you can follow along!

Choosing the right boards for your job can be daunting with many different options available to use for flat roof decking. However, some are much more highly recommended than others. In our video below, Sam covers the key differences between the most commonly used boards, OSB3 and S-Grade Plywood.

Generally, installing a ClassicBond roof can be a very quick job if you have basic knowledge about the preparation and the correct steps to take.

Some factors will affect the installation time such as the current substrate, size and type of roof; along with if there is any detail work required such as skylights.

Our friends over at RoofScout have made a great video showing you exactly how long it takes to install ClassicBond on a freestanding, timber-boarded log cabin.

For Sam, it took him just under a 1hour and 30minutes. He did install this roof alone and installed edge trims which make a difference to the installation time.
