Fibreglass GRP Roofing

Fibreglass Flat Roofing

A properly laid fibreglass roof also known as GRP Roofing, will last for at least 30 years with no measurable deterioration. The roof must be laid onto a dry deck in dry conditions at a temperature not below 5°C. The resins and top coats should be suitable for use in GRP Roofing. This guide relates only to the application of the GRP laminate and top coat. The deck should be of 18 mm exterior plywood or Sterling Board and be well fixed to the underlying joists. Typically Always try to plan starting the roof when a settled period of weather is forecast. The deck may be a new deck, or may be formed over an existing roof. You should ensure that the new deck is laid to adequate falls in order to allow good drainage, so that there is no standing water on the roof after completion.

Application:
When you have prepared the new deck, the GRP Roofing is carried out in the following sequence.

1: Trimming: Fitting the edge trims.

2: Bandaging: Reinforcing the board joints.

3: Laminating: Applying the GRP membrane.

4: Top Coating: Applying the final top coat.

Trimming:
The trims are supplied in 3m lengths and should be fitted as shown by nailing the bonding edge to the deck. The facia, drip and upstand trims should be bonded to an underlying slate batten (as shown) in order to support the edge. 

The A200 - Drip facia trim can be offset in order to ensure that the drip stands over the gutter. Preformed corners may be used, or if preferred, mitres can be cut into the trim to form the corner then sealed on site with a patch of glass fibre.
