We haven't renewed the full roof just the covering. We devided on rubber rather than re- felting. The roofer suggested adding a slight slope and gutter to assist with drainage. I just thought that adding insulation into the void would be beneficial. I understand that had the boarding been...

No venting that I know of. Rockwool is breathable though?

Thanks Johnny. Do you think it would be ok to push some rockwool into and along the space, one bit after another. I'm just a bit concerned about the lighting wiring.

I take it you re posted my first post because of my comment re access. What I mean is, when the rubber layers and slope built, because they were done over existing roof covering thete was no access from the top to add insulation then. However from the loft and storage space in my sons bedroom, I...

They both have minimum insulation from when they were built before we lived here but there is still mostly empty space. The sloped roof and the extention re- boarding and rubber covering were both built on top of the existing felt, so there was no access for additional insulation.

Hi, we had our extention flat roof re- covered with rubber a couple of years ago, also weve just had our dormer flat roof done the same with a slope built in. My question is, is it possible or even advisable to blow some kind of insulation to the gap between the foof top ceiling in each space...

Yeah cowboy job building the extension which the previous owner's had done. We discovered several faults after moving in, although this one had taken 34 years to show. Others included not tying in roofing joists at walls causing gaps to open up during cold weather, brickwork untidy and placing...

Sorry for delay. Thank you for all comments. I stripped the plasterboard from the underside (inside) in our sons bedroom from the sloping pitched roof area next to the dormer, as there was a damp patch at the section. Strangely there was a cut out in the lead flashing and I could see daylight...

Thank you very much. Yes I need to trace the leak. It seemed strange that they would run the felt beneath the layboard, thus causing the water ingress inside our property. Thanks again.

I've dine a drawing (not to scale) It shows the rain water flow running over the roofing felt and down the loose hanging end into the plasterboard lining the beam. Note the 1 inch gap that the water runs through between the felt and the thin board with the rubber flat roof covering inclining up...

We have a leak inside at the beam where our extention flat roof begins. Outside the flat roof meets a pitched tiled roof, with dormer. Rain water somewhere is getting beneath the tiles at the side of the dormer wall cladding. This is running over the roofing felt and as this felt goes beneath...
