FLAT ROOFS

Fibreglass flat roof systems

Fibreglass/ GRP (Glass Reinforced Polyester) waterproofing systems are used to form a durable waterproof membrane over a roofs surface, regardless of it's size and complexity.

With a large variety of colours and finishes to choose from, fibreglass is also a fantastic system for balconies and roof terraces, where the aesthetics of the roof are important.

No joins, No laps, No leaks!

Fibreglass really does tick all the boxes as a permanent solution to all the usual problems associated with flat roofs.

There are no joins, none at all, across the entire roof surface.

The system is applied as a liquid and cures to form a solid smooth laminate that is chemically bonded to the roof deck and any areas of detail such as flu pipes, upstands and sharp steps and corners, are easily sealed.

The GRP also has excellent thermal expansion properties which means it will not split or crack in extreme hot or cold weather

Will I need to replace the whole roof in

20 years?

The roof structure should never have to be changed, once installed correctly. Typically around 25-30 years after the installation, the roof will be thoroughly sanded, cleaned and keyed; then an additional layer of the fibreglass can be applied; giving you another 25-30 years of life all over again.

Fibreglass roofs are widely regarded as 'permanent flat roof systems'.

I think you can see why..

Is it expensive?

Single ply membranes are generally more expensive than traditional felt roofs, although it does depend on the installer.

There should be a noticeable difference in price between renewing with a felt roof system and a single ply membrane system, purely because of the difference in material costs.

Prices can range between *£80 - £150 per square metre, of an installed fibreglass roof.

A felt roof should range between *£45- £75 per square metre.

There are of course, a large amount of variables to take into consideration ie:

Job specification - Materials needed, rot/ damage to repair, insulation requirements, trims & finishings etc.

The size of the roof - Typically, the larger the roof, the lower the cost per sq/m. The smaller or more intricate the roof, the higher the cost per sq/m.

The access to the roof - Height? Does it require scaffold? Is ladder access difficult?

The location of the property - Rural or inner city properties can incurr extra costs to the job. Fuel, parking, vehicle wear & tear etc
