Stages of Installing a GRP Roof

The installation of a GRP roof can be divided into 4 stages:

1. Preparing and decking the roof.

The old roof covering is removed if necessary and the roof is re-decked with OSB3 18mm tongue and groove boards.

2. Fixing the edge trims.

GRP edge trims are fixed to the perimeter of the roof and can be used to adapt the laminate to almost any specification.

3. Laminating


Joints between decking, gutters, GRP trims and protrusions ;e.g. rooflights are bandaged at this point. The entire roof is then laminated with a layer of GRP.



4. Topcoating and finishing.


The roof is then topcoated, with the client’s specification of colour and finish.
