rafters

I wish to build a metal stud wall to partition my loft, there is a loadbearing brick wall I can build upon BUT if built there the ceiling runner ends up centered parallel with the rafters and have nothing to attach to. The best I have come up with is adding some noggins (in red) 600mm apart...

Hello, I'm putting some new rafters into an edwardian butterfly roof, on the advice of a structural engineer, and when it rains there appears to be large water marks forming on the membrane. No water is getting through, but in the darkest spots, around the valley, it's starting to feel slightly...

Hi all, I'm looking for some opinions on the cause of some wet rafters in the attic. The rafters to the rear (north facing) elevation are all wet on top and down the sides. The rafters on the front (south facing) elevation look to be okay. I'm trying to work out if the likely cause is a roof...

I have a small amount of water coming through what looks like a crack in the render on the corner of my chimney inside my loft. My thoughts are to chisel away existing render in area and rerender. The problem the roof rafter that goes up is right against the chimney stack. Any suggestions how...

Hi all, just looking for help with my dormer conversation. I’m installing new roof rafters 150x50 and sitting these on the load bearing eaves to which the original rafters from this to the wall plate are to remain but I have a couple of problems. -replacing the whole rafter will make the roof...

Hi, I'm having a vaulted ceiling and a Ridge Steel has been fitted. Internally, I want a triangular ceiling. I was wondering how the rafters should be fitted on the steel. I've attached an image with two options. 1. where the rafter fits into web of steel with noggins 2. add a bolted timber...

Hi, I'm constructing a roof for a single storey extension. The roof is composed of two parts, one gable (vaulted ceiling) and one flat roof. I've attached image. I'm under the understanding that usually rafters from an inclined section are connected by a birdsmouth, but internally this will...

Hi :) I have just bought a house in need of much renovation! One room is flat roof and I am unsure if I need to add any insulation between the rafters or if there is a layer of inuslation above the boards and the space between the rafters is for air flow. Any advice welcome :) Thanks

Hi there. First time post - nice to meet you! I'm planning a self build timber frame garden room with a flat roof that has an internal span of 3.3m. From the span tables I've seen, 6x2 on 400mm centres would be best - based on minimal loads as doing a cold roof and wont be up there often and...

Hi I purchased a 1600's house a few months back which has historical woodworm (obviously) but following 2 independent assessments, no sign of new infestation. However - having had a *really* good look around the loft, probably 10% of the rafters have been well chewed through and I suspect need...

I have come across some random plasterboard in-between a few of our loft rafters. The previous owners had a two-storey extension built 10 years ago with some new roofing that joined onto the existing roof. There is some overlap between new roof felt (beathable) and the old existing felt (the...

Hi, I'm installing a flat roof on a single storey extension. I'm installing the first rafter and unsure how far it should be from the adjacent wall that runs parallel. Is there a set distance or does butt up to the internal wall ? I will be adding insulation in between the rafters so not sure if...

I probably already know the answer to this question but I will ask it anyway. We had all the roof tiles replaced about five years ago and afterwards I renewed the loft insulation and boarded the loft. I also fitted 2" thick polystyrene between the rafters, the polystyrene being cut into tiles...

Hey everyone, I'm new to this stuff so thanks for all your help guys! :) Sorry for the long post! Summary: Trying to fit curtains onto a bay window but there is no wall to screw into above, only rafters. Detail: There is no wall or lintel above my bay window. Basically, it's a normal pitched...

Hey everybody, ~1950's two storey hip roofed house, with part of the roof extending down through the 1st [UK] floor: The original rafters are suprisingly small (45 x 70mm), despite some of them going nearly 8m to the apex. The main hip section of the house has been insulated for a while, but...

I’m in the process of building a lean-to on the back of the house and wondering if anyone has any alternative methods of securing the Eaves plate two two separate brick walls? I would normally use wall straps, but I’d sooner not see the metal work, as I’ll be keeping the walls brick. Each...

Hi Guys, I am about to put in my insulation between the rafters after my electrics first fix, The question being do I put the insulation in so they are flush to the bottom of the rafters or can I put them above my wiring as long as I leave my 50mm air ventilation gap? There will be 50mm pir...

Evening All. I am about to start constructing the roof on my extension, which is a typical single storey, with a lean to roof joining the house. The 'lower' wall plate, I.e. the one sat on the blockwork is best made from either 50x100 or 75x100 timber by the sound of it, to give enough to nail...

I have debated installing loft insulation...... My house is a 4 bed detached and i pay £100 per month for gas and electric. Joists are 70mm so putting insulation in between joists is futile and impossible as thinnest width i can find is 100mm. And i am not stupid enough to start raising...

Hi all, we are planning on adding a pitched roof to an extension we want to build with Marley concrete tiles on it and two roof lights in it. The total span will be about 5.5 metres. 31 degrees pitch. Which leaves the rafters length at 3430mm and the rise 1646mm What I wanted to ask is if we...
