Flat Porch Roof and Damp

[HandyHands]

I was round at a mates during the week, as he's been having some problems with a flat roof above his porch. There's no guttering around it, and no obvious signs of drain holes, so rain water just runs down the walls. This is now causing damp on the inside walls around the door.

Roofs are not my area, so I said I'd post some pics to see if anyone had some suggestions on what could be done.

he needs the services of a good flat roofer who will:

remove the house gutter.

remove a few courses of tiles from the eaves up and form a plywood tray.

fix a drip batten to the concrete roof.

cover the concrete roof using a decent rubberised/bitumen roofing system, dressing the membrane up the pitched roof.

re-instate the house gutter.

fix a half round gutter to the flat roof, draining into existing system.

Thanks noseall - I'll pass on the info.

I was thinking he'd have to build-up the level of the flat roof in order to join into the existing guttering, or fit a gutter around the flat roof and lead this into the downpipe - some distance away though.
