I would be interested to know if the problems is greater with Tru-tone/slate type tiles. I would think that the older cement type roofing tiles would absorb the water and allow the roof to breath
My storage tank and heating tank has been mounted about 6 feet up in the loft, on a timber frame, I don't know why, but it is imposible to lag it or keep it warm. Is there some new logic for doing this? possibly better pressure for the shower, should I get a plumber to relocate it above the hot press.?
It may not be unrelated to the velux - they can cause pockets of dead air to be created above and below them by the trimmer rafters interrupting the continuous 50mm air gap there should be above any insulation following the slope of the roof.I have noticed several small damp patches on plasterboard in attic partial conversion near ( but i think unrelated to ) velux window in our 7 year old house - this has happened in the last week and I assume has something to do with the very cold weather and condensation...
It depends on whether or not this vent was intended to receive a hose - it should have a facility to receive a circular hose or clip a connector into place.Checked out attic insulation and discovered one area between rafters, about 5 feet in length had no insulation at all ( I've filled in the gap with some spare ) and also in the main attic the extractor fan from the infrequently used ensuite vents directly into the attic space !!!
Is this a big deal and can I fix it by attaching a hose and directing the extractor air to a nearby vent in the eves ???
Also while i'm up there should i cover the 2 large water tanks and if so with what ?
Thanks
Thank you onq for that very comprehensive reply.
I thought the damp patches were unrelated to the velux because they follow one horizontal line extending between 1 foot and 4 feet away from the actual window, at a height that is 2/3 way up the velux (it looks like the condensation is running off along a joint/beam???) I'm hoping that the missing insulation being filled in might rectify the condensation there as it was in the side attic off that room...
Re. the vent in the soffitt in the upper attic I'd say it's definately there to ventilate the attic as it is the only vent on the high gable end of the house and there is a corresponding one on the other gable...so I better not divert the extractor fan air that way. Might try to get the builder involved, but it's 7 years since he finished so that will be a long shot (well he's a nice man, and probably not too busy right now !!! ).
I noticed that the downstairs toilet cistern which is fed directly from the house main supply, was condensing water so bad that it was running down and across the tiled floor...
...they also took the ducting from the extractor to the soffit vent and no further, so it is not exactly going outside. (not sure how to do this yet) do these vent just click into the plastic soffits?
My extractor is installed in the same way as described... I would be interested in other alternatives?
I experienced the same over the weekend with the toilet.. never seen this before!
The issue is possibly exacerbated by the temperature of the supply water dropping - I've certainly noticed drop in temperature of the [potable] cold water tap in the kitchen as the cold spell continues.Just to report back. The weather must have been really exceptionally humid during the last few days causing condensation. I noticed that the downstairs toilet cistern which is fed directly from the house main supply, was condensing water so bad that it was running down and across the tiled floor, I never saw this before, we thought at first that one of our guests was missing the pan. This has now stopped as the weather became dryer.
Just remember that these are extreme conditions and that matters will tend to improve.Of course this has shown up faults in many people’s attic installation which now require drying out and fixing.
I found that the builders had installed the insulation over the soffit vent which I am in the process of fixing, they also took the ducting from the extractor to the soffit vent and no further, so it is not exactly going outside. (not sure how to do this yet) do these vent just click into the plastic soffits?
I have also the freezing tank problem to fix.
You are all very welcome - no point letting a difficult situation become a crisis due to lack of knowledge and I am always happoy to stand correct also - the most dangerous assumptions are based on obsolete information.Thanks "onq" for all your advice
