I'm currently side extending and loft converting a bungalow on a, where possible, DIY basis. I have a couple of dormers to build, one has a relatively simple flat roof. The second has a largely tiled pitched roof with hip but to stop it extending above the ridgeline is topped with a small (approx 2x1m) flat roof. I'm considering using EPDM for both flat roofs primarily because the of the lack of joins needed and it looks relatively DIYable compared to torch on felts or GRP.
Question is: How would I create the transition from flat roof to the Redland 50 double roman tiles. I have seen pictures of this being done with felt being layered over the top row of tiles and then ridge tiles being bedded over the join leaving a couple of gaps to allow the flat roof to drain. Is this arrangement possible with EPDM, can you get it to adhere to profiled concrete tiles or would I need to transition to lead flashing 1st? Any ideas?
