Flashing job on to tiles

JCL00001 · 16 Aug 2019

My porch roof is letting water leak through. I would like some advice as regards what to do about the flashing which is on the tiles and whether its best to repair the fiberglass or get it felted?

Would I have to grind the flashing that is there off now and attaching the felt under the tiles or could the felt be attached without having to remove the flashing?

I feel woozy.

Wow! that's a novel idea, whoever came up with that solution hasn't got a clue.
The way forward would be to cut the tiles free and insert some lead behind the tiles making sure it also goes behind the felt if there is any.

Im sorry to ask but is this a serious enquiry, or are is this a wind up? -I apologise if its serious, its just that this forum gets a few wind up merchants.

If its serious...Mmm, well you have a few minor issues.......

Are they roof tiles being used in a VTH application.

Looking @ the tile overlap and the angle of the fibreglassed bit just looks odd - even the angle between the 2 - let alone the fact the tiled roof appears vertical due to the photo.

Thank you for the replys, I posted this elsewhere and this forum is much more responsive.

I was thinking of that as the solution it's good to have someone else thinking the same because one guy who gave me a quote for the roof didn't seem to think this flashing issue needed fixing.

I am serious, it is a bad job all round. Mould and dampness is coming into the porch in a long line towards the back and at the front end but not as bad.

My fault I was on the ladder with my phone and the angle I took the photo was bad. Slightly sloping house roof.

I'm still disoriented. If the tiles are the "slightly sloping roof" then the flashing is up a wall meaning that that's a glass fibre valley, right?

Low pitch house roof - maybe the water is tracking down the overlaps @ the edge of each tile - then under the fibreglass. Cover those laps with individual strips of flashband , tucked under the next row up . Won't cost much and if it don't work you can cut them off and do a lead flashing.

Its hard to visualise how a porch abuts a tile pitch roof.

In general the flat roof needs to return up behind the tiles, then flashing to go further up behind the tiles and run down over the flat roof.

The correct detailing at the sides of the porch need to be correct as well.

Wtf? That's one of those MC Escher pictures that don't make sense however you look at it, and does your head in.

Its a C*ck up, but saying that the leak is probably via the tile channels directing water in behind the upstand

if that is a flat roof to pitched roof abutment the attached detail shows the principle of waterproofing this situation
