or an explanation?

I think on a normal pitched roof the membrane hangs loose and creates a valley so that there should be passage for water. Difference on the vertical dormer is that the battens and membrane are tight against the sheathing so water would have to go over the horizontal batten and not behind. I...

Thanks , I may have made a mistake already then by putting membrane then vertical battens ... It's on a dormer with sheathing ply

Hi, I'm still in the process of rectifying my house of 1947 period ex local authority house. I made mistake of digging further to remove top layer of screed too. I had a lot of sitting water under mine however. There is no dpm as the tiles and the glue was. As pointed out before. In 1950s...

Hi, building inspector said that they "like" to see counter battens for newly clad dormers in case of moisture on the battens... It's messed all my measurements up on tiling but can't find anything that says it is a legal requirement? What's the deal. Local, national or just inspectors...

Hi, Can anyone show me an image of how the framing of the fascia and soffit should meet the pitched roof. I've been told by neighbour builder that the fascia and soffit should go all the way into the roof and then lead all over that. Fact is there is an internal gable wall stopping that and it...

Thanks for reply and info. Do you have an explanation of the connection between the cheek fascia and soffit with the top of the pitched roof and ridge? Will this also need lead or do I take the rubber over ridge and tape the corner?

Hi All, I am in the throws of building a full dormer on the house. Standard ugly looking thing Will be plain tile hung to all sides with EPDM and warm roof. Two , or maybe more questions... I can not find any details about flashing AND soakers for a plain tile dormer cheek. I have come to the...

Dormer Loft conversion

I see. Mine doesn't even specify bolting.

Here is the beam over the gable end wall without the smaller steel installed yet.NewRidgeSteelBeam by Bowlzi posted 27 May 2017 at 8:49 AM should the ridge beam sit directly on this small beam? Thanks

The beam being craned in 3rd story. Only had 25mm to play with above beam and nothing to play with each side as it had to come in almost exactly where it was going to finish...

The beam now installed

Hi, Perhaps I should start another post but as it is to do with this beam ( now installed partly) I'll leave it here for now. Question. Should the new ridge beam sit directly on top of the 127x76 13? It seems such a small beam with only a 4mm centre yet I'm about to sit pretty much the whole...

I actually have plain redland tile so this is incorrectly listed in the calculations...

Yes sorry original question has morfed into a beam query. Insulation 130mm I'm sure SE knows it is bolted to a post but does not want to back down over size...

Thanks, Due to the brevity of the drawings I am having to interpret where beam A will actually sit. My initial thought was this was directly below the ridge beam. I have no drawings supplied to show this location ,such as a cross section, and SE said any competent loft converter will know...

Reply from SE... ----- The steel beam needs to be a 305x 165 x 40UB s275. Or a 203 x 203 x 46 UC s275. As the beam has no real end lateral restrain, i.e. It can rotate as there is insufficient brick work to stop the beam from rotating, British Standards request me to increase the beam design...
