As KIAB, point of exit can be quite a distance from point of entry, I remember chasing a leak in a factory once, water was coming through a damaged felt roof and tracking along steelwork for around 20 metres before heading in.
You might find that water is getting through the felt & running down on to the lintel, hence why it's rusty & there is enough fall on it, for it to run away from internal walls, ceiling, therefore no tale tale signs of internal damp patches.
Im on the roof now. So as you can see the edge of the felt goes direct into the gutter with a piece of plasitc sat in there to help direct it. but looking at where it curves over its cracked and im guessing this is my problem? also a section above the window has been ripped and can be lifted so this wouldn't help either? another shot of the wood underneath. the first photo the ripper section, about a foot long 2nd same 3rd crack in edge of felt as it goes over to the drop 4th gap between wall and guttering with felt lifted 5th wood underneath 6 & 7 just shots stood up looking down at section
Well,looking that felt, photo 3 it's had it, photo 5 wood looks wet, so I wonder what condition is the decking is in. Ideally I would be looking to replace the the lintel over the widow, as it's only going to get worse, & in time rust stains most likely on brick work, maybe internally as well. You could go again with felt, which will need replacing in around 10 years or so, or go high tech with something like glass fibre, there no seams, should last well over 30 years, & Topseal is the only GRP system to be BBA Approved. http://www.ribaproductselector.com/...s-product-guide/12946/col916314/download.aspx http://www.topseal.co.uk/ Here a firm fairly close to me, they didn't do my bay window roof, or workshop roof though,I have had glass fibre down six year now, very satisify with it http://www.stroudfibreglassroofing.com/home.aspx
The cost for a fibreglass roof is higher, but this is offset by it's life span, & it's much harder wearing than felt & 100% seamless, so no leaking joints.
Looks like the problem is solved. The roof is leaking and the lintel drain-off can't cope. Looks like the water is getting in behind the fascia, into the soffit area, running back to the wall on the soffit board and down the wall. Lots of it when it rains heavy. And if the soffit board actually sits on the top of the wall, even worse. Bad soffit fitting. Should always ensure a slight fall outwards for soffits for exactly this reason. Sort the roof, you will have no more problems. Mr. HandyAndy - Really
Hello all, Thank you for all your advice. This forum is pretty neat and I'll be sharing it with my dad as he enjoys a screwfix mag I've been in touch with a roofer and he's coming to look at it this week. We're going to go for the fiberglass fitting as it makes the most sense. I just hope the damaged already caused to the wood, soffit and walls isnt too bad. I guess if the wood under the roof is damaged the roofer will be able to replace this.
just to add, ill get the lintel replaced after the roof is done. From a previous post i guess this is a job for a builder.
Do the lintel before you have the roof replaced, it's very simple job,a lot easier, your roofer could probably do it. You can cut back the decking to get better access if need be, something you can't do after it's been glass fibred.
