| Non QPR - Repairing a cracked fibreglass roof 10:14 - Oct 5 with 3255 views | 1MoreBrightonR |
My extension roof has various cracks across the resin at the top, and in the latest bout of biblical rains, I've started to get a few damp patches in my kitchen.
Does anyone have any experience of adding new resin to the roof? any recommendations?
Came across this product that seems to get good reviews: https://gooforit.co.uk/emergency-repair-systems-kits/flat-roof-repair-kits/fibre but is also twice the price of other fibreglass roof topcoats/resins. |  | | |  |

Trying to patch old fibreglass roofs is throwing good money after bad, from my (admittedly limited) experience. Rip it all off and replace with torch-on felt. Should last 60 years if done properly. |  | | |

Sadly it's not old....4 or 5 years old but clearly not installed properly and highly unlikely to pin down the original builder at this point to deal with the work. | | | |

If its cracking already it needs ripping up and re doing. You will always have problems if you just patch it up. In my limited experience with GRP it sounds like it wasn't sealed properly so air pockets are under it and that's where the cracking is happening. I don't know any roofers in Brighton to help you out unfortunately otherwise I would have recommended a couple. Obviously this is the Internet so don't just take my word for it but that's what it sounds like to me. |  |

Sounds to me like you've suffered thermal cracking, GRP is a great product if installed correctly, when I was working we used to use specialist sub-contractors on the very rare occasions we had to have defective installations repaired (under warranty) however these are very costly companies and hard to find.
I doubt if MJs would have been required it being a small installation, think you might have to bite the bullet and start again.
A couple of major roofing Companies we used to use have gone 'tits up' since Covid arrived.
You might also consider using/contacting the Roofing Federation. |  |

We used some stuff that was liquid fibreglass (I think, they did explain it was a while ago).
You apply it to a roof and it sets forming an impervious membrane.
You might be able to try this as a temporary fix. |  |

Is the product still under guarantee? If yes, the company rep will tell you if the installation was incorrect and in what way.
Long time since I worked with that method of roofing, thought it was pretty good at the time. As far as I can remember, it was repairable, you may even be able to go straight over it with more coats. As I write I think (dangerous), did they put new ply down? | |

cheers everyone for the advice. someone on the street has recommended a local roofer on the street who can give me a professional opinion. The builders' are barely in business now that did the work, so literally no idea if its under warranty etc or even who supplied it. They were nice guys but I'll be happy to never have to deal with them again. | | | |
