Hi All, I've recently replaced an old poly flat roof with a warm deck EPDM rubber one and would really appreciate some advice/ideas on how to finish the job. The new roof consists of: 18mm OSB3 screwed into of ceiling joists Damp proof membrane 100mm Celotex foil faced insulation board 9mm OSB3 top deck topped with a EPDM 1 piece rubber top (stuck with adhesive to the top deck) Now I need to: - Add the PVC fascias to cover the extra wood/insulation height - Affix the PVC batons around the roof lip to allow the kerb + drip edges to be nailed in place - Affix the left + right kerb edges to stop rain going off the side - Affix the front drip edge - Put the guttering back up The thing I am having a hard time with is that I am unsure where/how to secure the new fascias and PVC batons in place as i have nothing at the lip to nail into besides the 9mm OSB... Some ideas i've had: For the Fascias: 1 - Nail the fascias to the gutter board at/just below half their midpoint and then nail the batons into the top of the fascias however this may not be secure? 2- Add another extension piece/replace the gutter board with a wider piece so it comes higher up the OSB/insulation however again this would only be fixed to the joists/18mm OSB which would be about 1/2 way up its height. Then nail the fascias ontop of this. For the batons/kerbs/drip edge 1 - Nail these through the Fascia board and 'try' and get the nail to sit within the 9mm OSB (if it comes out of the top it will pierce the EPDM . 2 - Have the batons/drip edge lower down so they are affixed to the gutter-board/18mm OSB3 rather than being at the roof lip (not sure if this would cause issues?) (+ i'd still have an issue with the left+right kerb batons going into the 9mm OSB edges) Some pics of the roof/drawings of what i've done can be seen here: https://drive.google.com/file/d/1qe_gmBaC4renUapX7TfsLbstYo3KErWw/view?usp=sharing https://drive.google.com/file/d/1Nr1JfafyYwlW8sj41l05Tertc3a8K6Rj/view?usp=sharing https://drive.google.com/file/d/10N-JmROkPnnHWaA2YH0r92Lwiw_GcVQM/view?usp=sharing https://drive.google.com/file/d/111uqoLBEpwof2uSsS-2Epm0K3swFDfsz/view?usp=sharing https://drive.google.com/file/d/11HvAkEo_1lYbMiLE6dYY2TLs_M9fVj8J/view?usp=sharing https://drive.google.com/file/d/1mxLar5hnYmPap_YuaoVhTdpp6wXD9dAp/view?usp=sharing Any ideas are appreciated!
