Hi all,
I had a really bad job done of my flat roof and since then it has leaked and no come back on the so called professional so I’m going to EPDM cover it myself. It was setup as a cold roof by the roofer but after learning more and checking the work I found that it looks to be poorly vented.
In the picture below the joists run horizontally and it is only vented on the wall side labelled B and opposite at C between the 3 first joists. Wall A is where the flat roof joins a pitched slate roof. All other sides don’t adjoin anything else.
There is a 75mm void between the insulation and roof boards.
If I was to turn it into a warm roof it would mean new insulation at £5-600 on top as well as making sure I join into pitched roof ok (as a diyer).
I got a few quotes and some said the venting wasn’t really necessary. One said just vent at one end (C) and others said warm roof only. Quotes were £3-5k so above budget unfortunately.
So, with all the varying advice what would you recommend I do?
The room will one day become a bathroom and a small other room so could be quite a wet atmosphere.
Thanks for your advice in advance
