Flat roofs have a notoriously bad reputation by many property owners. Regardless of the system, poor installation typically leads to premature failure and a roofing leak. As a property owner, you typically want a reliable membrane. Fibreglass, when installed by a professional team accompanied by high-quality materials and protected by a full range of guarantees can expect to last 30+ years.

Standard rates for fibreglass roofs in the Bristol and South West area range from about £70 to £90 on a square meter basis. These can fluctuate depending on the scale of the project and any additional work involved, such as asbestos removal. 

Fibreglass roofs are composite membranes designed to provide maximum waterproofing via a seamless, mechanically durable finish. They are made from glass fibre CSM reinforcement and a polyester resin matrix phase and are applied to the underlying roofing structure (typically timber decking).

A fibreglass roof can be installed on a range of flat roofs, such as property extensions, garages, orangeries, dining rooms, balconies, walkways and terraces. They are also popular in industrial and commercial applications, owing to their long-term robustness and durability. 

As a flat roofing material, fibreglass provides exceptional waterproofing and overall durability largely unrivalled by other membranes. With extensive real-world examples spanning decades, it is virtually unrivalled. 

Hiring a professional roofer to evaluate (and if necessary) install a new fibreglass roof on your property is a wise decision. However, to ensure that a reliable outcome is obtained and you have full protection in the event of a membrane failure, roofers should offer a high-quality fibreglass roofing system with a range of guarantees covering materials and workmanship – with an insured guarantee.

Installing a fibreglass flat roof is possible if you’ve got a reasonable amount of DIY skills. The fibreglassing step is the final stage of the flat roof installation and the underlying timber structure and insulation should be correctly installed. Note that following an installation guide is strongly recommended and is available with fibreglass roofing kits.
