conservatory roof leak

gov

Senior member
we had our new conservatory built 3 years ago - never had a problem till now - there's a small leak from the joint at one end of the centre rafter where the ends converge - I've taken the internal end cover off and can see there's a small drip coming from directly above - difficult to see why because directly above is the external end cover - the roof is glass . Is it worth trying to put sealant up into the joint internally - there is a space where all the end panel glass sheets meet - difficult to fill with sealant - the other end of the centre rafter is exactly the same design with the same space but doesn't leak - the conservatory is 3 1/2 m in depth and 7 1/2 m wide with a box gutter where it's attached to the house - I suspect there's a leaky seal but to get to it will probably mean dismantling the roof ( a major job :( )

Any suggestions ?
 
Internal joint sealing has no benefit as the water will find a way somewhere else as there is a leak (obviously).

Afraid you need to seal the leak from the outside ...
 
Who put the conservatory up? Might be worth chasing them as I don't think it's unreasonable to expect a roof to be water tight for at least 15 years. We had a conservatory extension added to the bungalow in 1992 with a solid flat wooden roof which was felted and it sprung a small leak in 2012 so lasted 20 years. We had it refelted. I thought most Windows and conservatories had a gurantee of 5 to 10 years these days.

PVR is quite right Gov, once the water is inside it'll work it's way out somewhere no matter what you do.

Could you take the external cap off and pack it with sealant? It's a good starting point I think.
 
Thanks - guessed it will have to be done from the outside - I 'll text the installer so he can have a look as you say it should still be under guarantee .
 
If you have to use sealant on the outside i.e. repair it yourself then I recommend CT1 unlike the silicon sealant we're familiar with this stuff will work on a wet surface.........had it demo'd to ne by City Electrical rep and they supplied it but I'm sure it'll be available at loads of DIY type outlets.
Hope you get it sorted before it causes too much interior decorative damage
 
Installer may try to wriggle out but you have 6 years protection in England, only 5 years here in Scotland though. Check out the Sales of Goods Act. It is reasonable to expect a 3 year old roof NOT to leak.
 
When you chose the installer I suppose you chose a one with a good reputation?
He will no doubt want to keep that reputation so best to have a word with him.

No doubt he will be a member of window trade association ?
