Fibreglass Roofing Cracks

kaktus · 27 Dec 2016 at 15:22

I was sweeping a pool of water that collects at the edge of my fibreglass roof above kitchen extension just now and noticed that the fibreglass roof grey coat (i think it's the topcoat?) has numerous cracks in it where the water is pooling.

This is not linked however, it pools because they didn't slope it properly.

Anyway, what's the best way to fill those cracks in without having to redo the entire topcoat? The rest of the roof is perfectly fine its just that one area near the edge which is pooling water and has cracks in it.

Bath/Kitchen moisture resistant sealant when the roof dries?

Get some fiberglas and resin and patch it over. 20 min job

Agreed , this is why fibreglass roofs are popular, super easy repairs

Thanks

Would any of you have a guide I can follow? Not sure what exactly to buy or how to do it. I tried googling fibreglass and resin repair kit and ended getting some articles about how a topcoat needs to be 0.5mm thick or it will crack.

Basically never done it before and no idea what fibreglass is and how to work with it.
