Flat Roofing

GRP Fibreglass and Firestone Rubber

Garage Flat Roof EDPM-roof Nov 2013c 008

Cansfield offer what we believe to be the two best flat roofing solutions available today- Edpm Firestone Rubber and GRP (fibreglass) roofing. These two systems cover all flat roofing situations and are on a par with regards to life expectancy.  Whether you have an existing flat roof, a new extension needing a flat roof or a garage flat roof we can offer a long lasting reliable alternative to traditional felt materials.


EPDM is a single ply synthetic rubber membrane which unlike most bituminous materials does not become brittle with age, EPDM will flex and resists all changes in temperature without cracking, peeling or pollution.

Our membranes come cut to the size for your requirement, which negates the problems associated with multiple joint, all potential points of failure, associated with traditional roofing felts. EDPM is available in any sizes up to a maximum of 15 metres in width and 30 metres in length. Most flat roofs are of a shape which can be covered in one single sheet, meaning relying onthe integrity of seams to keep the roof waterproof is a thing of the past.

Suitable for almost all flat or slightly pitched roofs including extensions, garages, dormers, porches etc with EDPM There are several systems that are used when fitting. Each system has its own individual points of interest and you can decide upon which fitting method best suits your particular application. We may not even have to strip your old felt etc.

20 Year guarantee with a life expectancy exceeding 50 years!

Once installed the EPDM requires little no maintenance.

Environmentally friendly – EPDM is an inert material which has a limited environmental impact during its manufacture in comparison to other membranes. When coupled with its high durability this makes EPDM extremely environmentally friendly.

Kinder to the planet
GRP is tough against leaks but kind to the environment. The longevity of GRP eliminates the cost and energy consumed by the manufacture of inferior systems which require repair or replacement at regular intervals.

GRP can also be specified to comply with Part ‘L’ of the Building Regulations concerning additional insulation if necessary, which will further reduce carbon emissions and save you money on your heating bills.
