The current design (not built yet) for the flat roof part of my new loft conversion falls back towards the ridge of the original pitched roof with a secret gutter running just beneath the ridge. A number of builders have commented that it would be much easier, and probably better long term to try to get the fall running the other way. I have raised this with the Architect who advised me that to do this would mean that the flat roof felt or EPDM (whichever I choose) would have to be simply lapped under the ridge caps and then pugged in with mortar which is his opinion was very poor practice, interestingly this is exacly how my next door neighbours loft conversion roof has been done! Anyway, I wondered if there were any other options for the junction of the felt/EPDM and ridge that are not considered poor practice? Perhaps there is a ridge cap product designed for this purpose?
Thanks
