GPR roofing 2" hole on on edge

donmaico

I noticed it today .The roofing ends in a ridge that runs right round the edge and there is a hole .In that ridge there is a gap into which rain water has gone in although I dont know to what extent The ceiling inside is not showing any signs of water penetration as yet but I guess the sterling board is probably holding that.I always thought glass fibre was pretty much bomb proof but clearly it isn't so i am now wondering what to do about it .I stuck a piece of lead flashing over the hole held by some silicon for now.Any ideas? Thanks

My first worry would be what state is the board underneath the hole in ? If the hole has only appeared recently then it might not be too much of an issue, but if the board has been soaked for a while then it may need some attention.


That aside, repairing the GRP is pretty simple. You can get glass-fibre matting and resin kits from loads of places - I know Halfords is not known as being the cheapest of places, but it's convenient :-) For example : http://www.halfords.com/motoring/paints-body-repair/fillers-preparation/davids-fastglass-glass-fibre-kit-large


I'm sure you'll probably get similar stuff online or elsewhere for cheaper.


I used tons of this stuff on my first car oh-so-many moons ago - the bodywork had more holes than metal :-) It's truly 'orrible stuff to work with, and if you get it on your skin it's a right pain in the proverbial to remove. But it is easy to use, and very effective. This would probably be the easiest and cheapest way to make a reasonably-permanent repair to the hole itself - as I say, notwithstanding any other remedial work that may be required to whatever's underneath.

I guess I would need to peel the fibre glass back a little to see how far the sterling board is soaked .If it is let it dry in good weather before repairing the GRP? What annoys me is I font understand why the roofers left a gap in the ridge I would have thought they would have inserted some kind of filler to prevent it cracking,after all people do walk on such roofs and rest ladders on the edge

I'm no roofing expert, but I think that would be a sensible idea - maybe cover it temporarily with loose tarpaulin or polythene sheeting whilst it's drying, enough to keep any rain off whilst still letting any moisture evaporate. Of course, if you find the board has already deteriorated badly then it may need to be replaced - which I suspect would be a much bigger job

Is it possible to post pictures of the area that needs patching to get a better idea of what's needed to be done? Those halford kits only contains the resin system and its the topcoat you need to seal it completely.

Which your company will doubtless be able to provide ? Spam reported.

Spammer for what?, just trying to offer some advice. You seriously think I would come on this forum to sell 0.2 litres (possible value of less that £2.00) of topcoat to patch a roof?

i have managed to find the contractor would laid the roofing for me and he will do the repair .Apparently the ridged edge is always hollow and can be damaged if people tread on it or hooked ladder is rested on it or a flying object lands on it.He said there shouldnt be a problem with water ingress
