loft

I’ve attached a drawing to show the existing, temporary and final diagrams to help show the question. The structural engineer has designed our loft with 2 floor steels and a ridge steel. The installation of the first floor steel (beam A) is simple, as nothing needs to be removed to install it...

Hey just want some advice I have just bought my first house and the roof is not felted. The roof is in fairly good condition only issue is that there seems to be a lot of dirt in the loft, it may of build up over time and the last owner probably didn't go up there much. It is already insulated...

Hi all, I recently purchased a home and found water coming through the ceiling in the upstairs bedroom. Turns out that the loft skylight seals perished and water had been seeping through, onto the joist, going down it and eventually to the ceiling on the floor below. The window will be replaced...

I am raising my loft joists (100mm) by putting new joists (170mm) across the old ones (perpendicular?), I plan to add more insulation and board an area so I can store stuff up there. My question is: how should I fix the new joists in place? Do I screw them down from top to bottom, long screws...

Hi Everyone, Recently when going into my loft to change the bathroom fan, I noticed that there was a huge amount of damp and black mould on around half of the timbers. I also noticed a smaller spot of what I think is white mould on one rafter and the felt around it. After investigating I found...

Hi, I'd like to board my loft and use it for storage and I'd like to move my combi boiler from the bedroom to the loft, to gain some space. I'd like to replace the current loft insulation with PIR to gain some height: 191cm is the highest point from the top of the joists to the rafters. I'd also...

Hi all, Recently moved into a house with a window in the loft. It’s in the gable end wall, and other than the glass looking past it’s best, it is great for natural light in the loft space. I’m currently insulating the loft floor and whilst measuring up started to wonder if the area around...

Hi, curious to know if anyone had experience with Dupre Vermiculite limited micafil insulation in the 1980/90s. Noticed a few bag of the stuff in my loft and got it tested to make sure it wasn’t contaminated. Though noticed the standard uk testing isn’t the best. Apparently the company was...

Hello, New member here. Have been looking at my attic recently, and wondering what the possibility of partially converting it either into a part mezzanine area above a bedroom or alternatively an insulated hobby/storage room area. Ceiling heights are limited at circa 1.5m, house is a Georgian...

Hi there, I hope you are well. I have a pretty bad condensation problem in my attic. I think this is due to the warm air meeting the cold membrane under the roof tiles. I currently have 100mm insulation in the floor and am planning to increase this to 270mm. Should I also add Celotex to the...

When it's very cold, moisture drips from the felt under the tiles of the roof. It could be up to 50 years old (70's house) so it will not be breathable. No issues whatsoever during the heaviest rainfall. Currently, there does not seem to be any source of fresh air (no eaves providing this) so...

Hello Previous owners had an extension built that basically acts as an independent structure with it's own boiler, consumer unit etc... and it's own roof. Didn't think anything of it when we moved in 2 years back but the valley where the two roofs meet has been a source of leaks, partly due to...

Hi all Hope you're well. I've just had my house re-roofed (new membrane, new battens , new thin edge sandtoft concrete tiles, and new dry ridge system). Following rain, the wooden rafters are getting damp in some areas (always the same recurring spots). When the rain stops and we have a dry...

Hello DIYNot forum members! I need to find a suitable and accessable place to add a switched 3A-fused spur for a boiler. I have two accessible rings to add it to: 1) Upstairs lights - not suitable, as it lives on a 6A RCD (B6) 2) A mysterious 63A RCD Protected Circuits breaker that gives power...

We have a problem with white mould on our rafters, which has been put down to poor ventilation. I am hoping for some advice on how to improve our situation ... This is a late 19th century terrace house with a London pitch or butterfly roof, which gives us two completely separate, shallow loft...

Hi I'm keen to insulate a loft with unusual construction (see below). I'm hoping that can be the usual "roll out some mineral wool" to a depth of 300mm (and raise any boarding above that by at least 50mm). But am weary of condensation risks (all the more so as this is a timber frame, timber clad...

Hi, I have a question about my roof. In the loft I can see daylight, from the outside it looks like no tiles are missing or damaged and on the inside it just looks like the underlay (?/roof felt) has come away - this definitely seems like a new issue as I haven't seen daylight in the loft...

Hello, I was looking in the loft of a 1900s house we've recently moved to, and noticed some tracks in the rafters that look like some kind of wood boring insect (images attached) - is that correct and is it possible to tell if old or recent? There's insulation below the beams so difficult to...

Hello, New here. I had a loft done by someone recommended to me who had their loft down also. Just boarding and kingspan used level with rafters with gap needed for ventilation. He advised I get tile vents installed by a roofer but I thought the vent laps do the same thing? Also, I could...
