Luckily clogged gutters and downspouts are quite easy to spot.
Condensation dripping from gutter.
If you stop air getting to the gutter you re problem is also solved a bit like insulating cold water pipes prevents condensate forming.
Picture a cloud of moisture floating overhead between the rafters.
In most cases you ll notice the problem as soon as you get a close look in your gutters.
Warm wet air rises and meets the cold roof and cools.
Drill a hole in the part of the gutter you want the water to come out.
Attach it to the wall using clips or gutter mounts.
Ideally you shouldn t have any dripping.
As it cools it can t hold as much moisture.
That excess moisture ends up as drops of condensation on the roof.
Unless you regularly clean them out your gutters can quickly fill up with leaf litter and debris.
It could be that the gutters have small holes or the fascia boards are starting to pull away a little and that is where the leak is coming from.
In cold weather the differential air temperature between inside and outside the conservatory is such that water condenses onto the lead at such a rate that it drips down the wall causing large patches of damp that will last throughout the colder months.
Solution 5 you could also buy a normal gutter cut it to the size you need and run it under the hole dripping the water and past the balcony.
You might get condensation on the underside of a box gutter but not normally further down a dry lined wall there would also be some different pattern staining between penetrating moisture and condensation is there a cavity tray in the external wall above the conservatory.
I always aim to have the condensate drain pipe come out just under the drip edge and extend an inch into the gutter.
Along that side of the conservatory is a rectangular lead gutter about 10 wide flat base and 3 4 metres long.
Sometimes here in north idaho on a cold blue sky day the east side gutter appears to sweat condensate and collect on the bottom of the gutter facia trim where it travels to the os corner and promptly drips on the steepest section of side walk below freezes and waits for ups fedx delivery man.
That puts it about three inches above any water or debris.
I d stick pu foam to the gutter with pu adhesive the fast set type to completely encase it and pack any remaining void with insulation and see how it goes.
It is internal to the conservatory.
