But how dry was the bone? 🤔

Storm just now . Pissed down biblical style . Gods final test for me .

 

We have good news and bad ….

 

Water running over the slab I.e the pig leak - seems good ; no leak. 

 

Both front upstands leak . This are really low to the roof - not 30cm as recommended but like 3cm worst case .

 

But it’s over the upstands so the seal between roof and window frame . Best to take windows up and refit I think ; tons of structural silicone then smack ‘em down .

 

Clearly this job needs to wait until next summer 😊. SWMBO wanted this room beneath when all the leaks finished , but obviously that can’t happen . What’s another year of stalling !?

Strange isn’t it . Had a tiny leak here about 2 yrs ago over the upstand . Bit of expanding foam all golden . Suddenly today ….

Still could be worse ! 
 

That corner is lowest of them all . So I guess if any are going to leak from the tiniest of holes it would be this one . Rains probably right up to the glass externally ( I can’t see it as decking masks it ) .

This thread continues;  though if admin could change the title to “ not THAT leak , this leak “

😂

Not funny anymore, just like this one.

Why not apply damp proof stuff to the inside faces?

Because that’s bodging 🥹

Actually I like this idea more ! I.e less work !

So the upstands are a mix of timber and structural silicon at the top where the frame sits on . So I need something pretty thick and sticky to coat that with . Needs to get in all the gaps . What should I use ?

All joking aside, how about a wet room tanking kit? Tape the corners & between the different substrates then paint on the flexible tanking slurry.

Yeah could work 👍

Is silicon recommended by the glazing firm to bond glass to frame and frame to upstand . Think it was called ssg4000 ultra glaze  or something

That is just an ordinary silicone sealant, it is the frame and glazing that are structural.

 

I suspect it is a high modulus sealant (don't move much in service), similar to what I used to stick the steam rooms together with.

Just what the company suggested to use

Decision made . Will take them out next summer . Bitumen paint asphalt joints around them . Structural silicone them back in . Delays the job by a year so that’s a win 👍

Got a pic from above that roof light?

Meanwhile throw some more money at it:

Ive heard that works well, @Onoff The glass at the top must have an overhang ? A liberal coat or two of aquaseal or similar on the upstand right up and lapping the glass underside of the overhang.

[Big Jimbo]

That water is coming down the inside of the wood, so right from under the glass. Your posh, fixing the glass down, silicon is letting water by buddy.

[Onoff]

Where's it coming from again? Under the glass, top of the brick or top of the slab?

 

 

 

[Big Jimbo]

@Onoff From an earlier photo, i would say from the top, under the glass.

[Onoff]

Before you rip up the glazing buy some of this and go around the glass to silicone joint.

Not 1 or 2 - that was the original problem !!

So 3 directly where glazing frame sits on asphalt roof .
