Yes . Felt over top of upstand also . I seem to recall concrete was deeper at the corner in question meaning of course up stand even shallower ..

Yeah . I ain’t got the height . Could just be silicone ( or whatever ) pushed up under that edge . Could smear it into a down ward curve I.e so it bonds back onto the asphalt....???

Here you go

The felt runs up the upstand and over the top . Then it’s the silicone , then the frame . As I said I assume a gap in the silicone at this point .

Demoing with cardboard. Perhaps some kind of collar ? . Maybe just stick some plastic beading to the corner of the frame - anything to deflect water way .... None of this would be visible once all complete

Yeah I know . But what bodge should I do ...... ????

Yeah . I read your post 3 times . I get your point and indeed water likes to travel where it shouldn’t. I can barely get a finger under that lip - but there is a gap . So I do think there’s a gap in the silicone under the frame - which of course is impossible to access . So wind pushing the surface water back at that corner is just enough to get it over the upstand and find the gap . Floor level ( when finished ) is level with the glass - so with stilted tiles all around it the problem could disappear. But I’d rather fix and know it’s done . Could just ‘stick’ polythene sheet to the frame at that edge . Not stuck to the asphalt- so water doesn’t get trapped . Not sure .....

problems not the roof . It’s the shallowness of the upstand and presumably a ‘gap’ in the silicone on the frame to upstand

Yeah the short upstand - I had no choice . Getting the glass out easy . Getting the metal frame off ... erm , structural silicon around all 4 sides and screwed down . I can’t see it coming off without destroying the asphalt. It’s quite possible that as the frame was laid silicone could of squeezed out into the outer edge of the T frame underneath . If ‘filling’ the void is a bad idea and removal is not really a good plan that just leaves ... Deflection ???

It’s a plan . That’s the problem though isn’t it . I can’t see what I’m doing . I could seal round the entire frame not just the front . Worried I could create a void that water runs into .... What about some form of deflection ? Like ‘gluing’ a lip to the base - making a ramp that runs away from the window ...

Could work .

Here was my plan to turn a dog into a unicorn ...

It is siliconed ontop . If I pour water all over the glass I.e running off it - no leak .

That better than ct1 for this ? Remember I need to get it up and under that tiny lip at the front . Old photo - before concrete pour then water proof layer then asphalt. Window on the right - you can see it’s a real shallow upstand after all that goes on .

I forget that this all began years ago so you lot may have forgotten ? Here’s a professional drawing

Nope . I’ve had many years of leaks to know the difference ?? . As I said hope pipe at it makes it leak.

Guys ! Ffs ! Been round this loop a zillion times ! This is the best roof type . It has never leaked . It’s all of 2 yrs old . The asphalt on top is *just* a protective layer - it is not part of the waterproofing. Rain is getting under that glazing frame . Upstands are meant to be 90mm min ? . But because of the balls up with the original roofer and the architect bit understanding I had to raise the upstands . But I can’t have the front higher than my front door . So the front ones are very shallow . This one the worse - maybe only 20mm . Walk on glazing metal frame has structural silicone under it - presumably there’s the slightest of holes there .

Not sure that will be particularly helpful but I’ll keep it in mind ?

Ct1 on a spatula and simply keep pushing it up under that lip until I can’t get anymore in . Still awkward - not sure I can guarantee a good seal .... Otherwise it’s some form of deflection so water simply can’t go up under there ...

Typically stopped raining ! Did this with the hose to reproduce the leak . Can only assume water and wind pushes it up under the metal glazing frame . So what / how can I get under that awkward to access lip ?? . Expanding foam ?? ?

I will do . I don’t mean caused the leak just the discolouration. Wonder if I could just silicone or ct1 the base of the glazing frame straight to the asphalt? I am now assuming it’s water pooling at that point and perhaps rain bouncing up under the frame . I’ll cover the edge to prove my theory . This is the shallowest upstand of all . Remember the original roofer completely screwed my roof up and I had to work around his bodge

Didn’t wait until Spring stuck hose pipe pouring over it . Couldn’t make it substantially worse . As I said I can see it coming in right at the top - so it’s nothing to do with the slab edges like the other leak . Also notice dark patches in the glazing coating . Assume my screws in the upstand have caused that ....?

So today for the first time I have a leak from the walk on glazing directly . I can’t see how it’s coming in . Can see it’s from right at the top near the glass . Silicone outside seems fine . Hard to imagine rain hitting the roof and bouncing up underneath the glazing frame . Assume I’ll have to wait until spring when it’s dry then hose over the glass . Bummer . Apart from the known leak outside the site could of done without this ...?

Finally got round to finishing the ensuite grouting

You can tell it’s nearly the weekend - people getting frisky ?
