FFS !! Ban all sheds, what a cock u are ! Fortunately not everyone is as thick as u might think ! I have never had any problems doing a rewire. I mean no dis respect to electricians when I say that it is an easy job, done sometimes by uneducated school leavers who do an...

Foil backed insulation is being used between the rafters. The ridge has no vents in it apart from the dry ridge kit I am using but it will be open via a dry verge along the roof edge up to the cap on the end of the ridge tiles, not air tight. Graham

Woah, test equipment, apart from circuit mains tester, errr no ! Full re wires of my houses and other peoples but before part P spoilt the fun. Electrics are not difficult but given the current regs and requirement for calibrated test equipment I will hand it over to a qualified...

Hi all, just another quick question, do I need a vapour barrier between the rafters and plasterboard ?? There will be an inch gap between the roofing membrane and the top of the 125mm insulation in between the rafters and the soffits will be vented allowing air flow under the tiles. It...

No, I am not one of those fools who do it on a building notice !!! I have re wired several houses successfully myself but never a roof like the one I am dealing with, and not since part P came in. I am competent but do not know the exact regs now, hence my question!

You are indeed partially correct, no detailed plans and drawings as I specified a rough build plan for the basic building work so that's what I got . It does state that electrical installation should comply to BS*** and be done by a competent person. The plans have been excellent thus far...

Hi all, am I correct in thinking I can still run my own wiring and just have the part P fella connect up and inspect?? If so how do I run wires inside this roof to be within regulations?? Can I 'spur' the new extension into the existing ring main as they did with the old...

A small apology for the build plan designer, it was 12.5mm ply :oops: OK, no ply but should I be putting a vapour barrier to the underside of the rafters ?? Graham

Hi all, thanks for all the replies and as requested here is a pic The ceiling is basically the underside of the rafters. another pic I have not taken any walls out but the existing openingl between the lounge and the new extension is being opened up from 2.1m to 3.5m...

Hi all, extension coming along now, and I am thinking about the inside. I am having a vaulted ceiling to the single story extension with roof lights. (ie the roof rafters form the basis for the ceiling and it will be the roof shape). The plans I had drawn up originally said after 125mm...

Thanks everyone for your replies, was making it all to complicated lol.

I have just seen a picture where rafters are hung using a 90 deg hanger and have just notched out the bottom of the rafter so it sits in the hanger correctly. Is this technique ok ?? Graham

Hi all, am at the roof stage and need to plan my rafters. New to roofs, as I was to bricklaying, foundations ect so go easy lol I have approx. 24 deg pitch to roof and therefore I need to attach the rafters to the ridge beam with a 24 deg cut, that I know. My question is are there...

is there a minimum that the rafter can be notched for the bird's mouth ?? My rafters are 150 x 50 mm I think.. ie can I not notch more than half way due to loss of strength, on the wall plate section?? Graham

Hi all, As far as I know at present the roof sits on the walls thus... My understanding is that I build the outer brick wall over the patio doors (2.1M) to a height of 2.4M and the inner skin of block is 1 block higher as shown. Then it's rafters attached to wall plate on inner skin...
