How to fit Firestone flat roof systems - Fully adhered application

Both preparation and installation of Firestone flat roof systems are important to ensure the best performance from your project. The following EPDM products will ensure a top-notch system that will offer longevity and reliability:


Note that quantities and trim types will vary according to your project dimensions and requirements. The Permaroof teams are happy to advise. Call us on 01773 441 947 or use the free EPDM Kit Builder App.

Preparation of the roof deck

Ensure the surface is free from debris, dirt and dust and is in good condition. Correct preparation is essential to ensure both successful application of the EPDM flat roofing system and long-term performance. (see additional resources below for full preparation guide).

Application of the membrane

When the EPDM membrane is laid over the surface area, allow the membrane to rest for around 30 minutes to allow packing creases to dissipate.


Apply the membrane from the centre of the roof, working out towards the perimeter edges.


Fold the EPDM back to expose around half of the roof substrate.


Use a 9” roller to apply water-based bonding adhesive to the substrate (timber only).


Roll the membrane into the adhesive and remove trapped air or wrinkles by smoothing with a soft bristle broom.


Apply trim as necessary to create a fully watertight, professional finish.
