I have a south-facing roof that gets the sun all the time and want to know how the coloured Fibrelast topcoat finish copes with the Sun, does it flake or discolour?
Fibrelast has built-in UV inhibitors to protect the roof from the heat of the sun, however, throughout the life of the roof you will see a slight discolouration but it will not affect the performance of the roof. Flaking on a GRP roof is generally down to poor installation rather than heat. What happens is the user will not wait for the main laminate to completely cure before applying the topcoat. Hope this answers your question
