rafters

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...

This is a section of my flat roof extension. The top rafters simply support a suspended ceiling below the original ceiling. The bottom ones are only approx. 500mm short and are placed inside the RSJ that supports the building and connected to the frame that supports the roof light, I cannot...

Hi I am looking to create a warm storage space in my loft. House dates to 1900 Original slate roof I want to insulate the rafters and eventually add plasterboard etc. There is no felt beneath the slate roof. I have not noticed any leaks up there. Can I add the insulation boards into the...

Hi all, I am in the process of replacing my gutters due to the rusting and leaking. My roof has exposed rafter tails and the corner tails have rotted due to the water damage from the leaking gutters. Does anyone have any suggestions as to how I can repair the rotted sections? I seen a few...

Can anyone suggest a budget (white) cladding to hang under rafters in a cold loft that will look half decent? I have to cover approx 16000 mm x 2600 mm So far I've found 3m long hollow PVC soffit. Will this be suitable? TIA

Hi guys/gals, I’ve recently had my building regs drawings through from my architect for a loft conversion where the truss roof is coming down and new roof put up, it states “restraint strapping - ceiling joists and rafters to be strapped to walls and gable walls, straps built into cavity across...

I appreciate things are hard to explain without pics but here goes. I have a square house with an attached square garage (just say it is the same size as the house) but this is set forward of the house by around 2 metres. I am building a small extension to the rear of the garage so back of house...

Hi, going nuts here a bit. I'm trying to do the dims for my garden office and am doing 5x2 roof joists with firring strips on top for the pitch. I am doing 400mm centres, but this does not seem to work to get the end of the OSB (1220x2440) to end on half the joist. I've read somewhere you do...

Hi, Just moved into a new build with a double garage. The double garage is a nice size and I want to use it as a man cave. The roof structure is formed of a complex network of slim rafters spanning the space. Over long spans, they are joined together using those thin metal plate rafter...

Hi there If I'm renovating an old property where the beams are to be exposed, what is the procedure regarding insulation? To meet building regulations what depth of insulation is required? I can only find regs for a pitched roof/ceiling where the rafters are going to be plastered over...

Hi, i'm erecting a timber frame garage. I have used 150 x150mm douglas fir for posts and beams. Do i need a wall plate on top or can the rafters be fixed to the top beam?
