Just to update this in the slim chance anyone has the same issue in the future. I finally worked out the issue. The builder who built my house initially George Wimpey who built similar estates nationwide generally at that time tiled using ludlow majors. My house which is an unusual style that wimpey stopped making in the 60s they used ludlow plus. The tiles look identical other than size! Theres nearly 16 ludlow plus per m2 compared with 10 ludlow majors. My neighbours house which is a different house style despite being built at the same time has ludlow majors. So my roof is around 75m2. Least the roofing costs will be more reasonable.

Not sure John I just noticed a lot of staining/seeping through. Next time I pass them I will check what face of the house its on.

Just multiplying the lineal metres of tile and counter I guess the tile shop must be saying I have just over 91m2 of roof tiles.

My roof doesn't have osb sheeting, its like old style silver foiled gyproc. Its starting to blow in and I think it would break up quite easily. I think around here they use osb3 and tyvec. I had sent the 2 pics in my initial post to my local tile shop, they told me 1096 tiles but having counted them myself I can see they were a little short or perhaps they were using the offcuts at the ridges for the other side. Anyway for battons they had said I need the following: 3 roll membrane breathable 240 lin mt 38 x 19 counter 380 lin mt tile batt A roofer had told me I only had 76m2 of tiles but I guess he's way off. The reason the m2 is important to me is a company quite near me are advertising a reroof on a detached house of upto 80m2 for £4480 inc skips and scaffold. I was trying to see if id be better using them or using a couple of roofers I know with me supplying the materials.

Thanks that rockwool looks ideal. What do you mean about the rainscreen cavity?

Ok so there is 1300 tiles, 48 third round ridges and 6 seg ridges. Seems a lot for a 3 bed house. Not sure how many m2 that is but thought it was normally 10 per m2.

I had hoped to put some sort of sound deadening behind the fibre board but guessing I wouldnt have much space

Also just on the subject of labour cost. My wall area is 107m2 that's with the windows and doors taken out. Its 130m2 with them left in, I'd guessed beading round the windows would be time consuming so had left them in for the calculations but I'm guessing your ballpark 22 per m2 per hour probably takes windows/doors into account

That's really helpful. I seen 2 houses being cast recently near me, both used powerwall topcoat. One done a scratch coat over the existing roughcast, like the old way of doing things and then applied a topcoat but the other just seemed to apply a top coat directly onto the existing 50 year old roughcast. Should the base coat be a powerwall/k rend supplied product or the hand mixed scratch coat? Considering just getting my own scaffold up and having the cast and roof tilies, fascia/soffit done at the same time so knowing ballpark labour figures really helps me, so thanks for that. Is there going to be much difference in finish from hand applied to using a tyrolean? I am guessing the gun will just be quicker to apply? Final question, at the front of my house I have tiles between the bay windows. I really don't like them and hear a lot of road noise in the upstairs of my house. I want to take them off and have them cast over, I am guessing they would just fit osb board and cast over it but am I giving myself any problem by doing so? Thanks

Hi Looking to get my house re roughcast and wondering what's the better system enewall, weber or something else. The house itself is from the 1960's. The existing roughcast is holding up quite well but doesn't look great. I noticed a lot of new build houses around here that are around 10 years old are starting to show like a red dye coming through the roughcast, doesn't look great but I have no idea what pre mixed stuff was used on the building sites. The houses did look good when first done but now id say they actually look worse than my old house. Something I am keen to avoid. What's the coverage like with enewall? I need 130m2 roughcast. Also if anyone knows a ballpark price of what I should expect to pay that would be great. Based in Glasgow. Thanks

Hi all Looking for some help working out how many m2 of tiles I need for my roof. It's a rectangular shaped hip roof and I have attached a picture of both the side view and the rear face. The front face is a mirror image of the back and both sides mirror each other. The length of the roof including the soffit is 9250mm and the width inc soffit is 7160mm. The ridge length internally at the peak is 2100mm and height internally is 2150mm. I have tried to work out the square meters but have came up with different advice on how to measure on different sites, would rather a roofer gave me a ball park quantity idea. Also I think the existing tiles are Ludlow majors could anyone confirm that? Thanks
