Isn't most of this stuff due to the roof being crap and letting water and moisture geting in where it shouldn't. I mean yes it's overall shoddy and wrong construction, but evens shoddy construction could still stand a long time, as long as the roof is built right and keeps water out, roofs are the most important part of a house. Seems to me you'd need to tear off the roof and make a new roof. Possibly replacing the loft roof as well and make a new single roof line that goes from the loft to the kitchen exenstion (and no skylights). I am not sure if that's just lipstick on a pig though. I've no idea on the windows because american windows and designs are unfamiliar, and I am not sure what I am seeing in your photos. Is the water between two panes, or is it water on the inside? The latter to me says the inside humidity is too high and the windows are cold so condensation forms on them. Got a humidity meter?

Seems to me a matter of how you define it. To me, heat getting to the roof so stuff melts on it, indicates an improperly built roof as the outermost layer of the roof should be separated from such a possibility with a ventilated air gap and a secondary barrier. But nordic construction probably differs. Improper insulation further down makes the problem of an improperly built roof worse though. The heat just shouldn't be allowed to get that far up to begin with. Not enough slope on the roof is also an issue, and using asphalt shingles instead of sheet metal (the snow just slides off the first chance it gets).

What is your indoor humidity like? Put up meters in various rooms, see if it's excessive. Then you have one more data point. I also wanted to know about the condensation on your windows, is the condensation between window panes, or is it on the inside, because I had trouble telling from the pictures. EDIT: Actually I noticed you swabbed a finger over the condensation, so inside it is. That is telling of high indoor humidity, or a very cold window.

Ooh ok on the outside, well I guess it means a leaky window. So the idea is moist indoor air leaks out and migrates up into the eaves and causes condensation, which then causes frost and the ice dam problem?

OK so it looks like multiple leaks to me, and I guess the problem is a leaky vapor barrier (and perhaps a leaky window) and possibly shoddy insulation compounding the problem. Do you have overpressure or underpressure in your house? I mean does air naturally wanna flow in or out of springs and leaks. If you got overpressure, all these problems will be magnified and moisture will be pushed through whereever it can. Houses here are designed to have a slight underpressure indoors because that's better than the alternative.

Our ventilation system (centralized with heat recovery of the outgoing air) controls both in and out and the out is slightly over what is pulled in. You could achieve something like that by adding a fan or several to pull air out. You could also determine this by opening a window or door and check which way the draft goes. As long as there isn't any wind at the time. His Divine Shadow fucked around with this message at 07:21 on Dec 23, 2020 |

Just how much humidity does a microwave produce? Never even heard of the concept of a vented microwave before.

OK so it's for the range, a must have IMO then. Negative pressure is the common way to build here, never had that issue. The vent is insulated at any rate, with a kind of "sock".
