Hi Guys, I have two questions. 1, all the images I have seen for warm flat roofs look like a sandwich with board, insulation, board. However im struggling to find any information on what to put around the outside and how I attach this to the flat roof, I could use OSB but then screw it into the top and bottom deck? Or do you run a batten on the inside of the sandwich, or not do anything. Im using 150mm insulation so was thinking of running a 150x40mm piece of timber along the edge of the roof to double up as something to attach the fascia etc too and enclose the roof and give me something to run the vapour barrier up around the insulation. 2, On one side of the flat roof it buts up against the second floor of my timber frame, however this is supposed to have woodfibre board insulation on the outside. Im not sure if I should run the roof upto the woodfibre, or install the roof under the woodfibre and bring it down on top, but then I worry about any water running onto it and keeping it damp. Hope that makes sense. Paul
Hi people, I'm new to the site and it seems to be very helpful in most situations so I thought I'd give it a try. I'm a roofer by trade so haven't done much carpentry/joinery and I've been asked by a client to put a roof starting from the joists. It's a new build (family room in the back of the garden) that's roughly 5.8m x 5.6m and the client is thinking about putting an RSJ in to stop the roof from sagging. Could this be avoided by tripling up 8" x 2" C24 timbers in the centre and going out from that at 400 centres? With an overhang the joist lengths will be roughly 6m long. The actual roof will be a warm deck Fleeceback Ruberbond EPDM and it may have a small (1m x1m) velux dome installed as well. Any help or ideas will be appreciated as I havent don't much carpentry before. I'd like to tackle it myself (with a friend) as I'm always wanting to learn more and it seems like a good straight forward one to do once I get a good idea of it.
