Temporary repair for felted flat roof leakage?
Hi All
we have a large-ish front porch which has a felted flat roof. Somthing needs repair... in the recent downpours we are getting water coming into the porch. It seems to be coming in at the corner of the porch ceiling and the house wall. I am resigned to getting a new roof fitted in due course (if its anything like other additions to this house it will have been fairly badly done originally), but I ain't gonna get around to anything substantive for a few weeks. I don't want the tiled floor or other parts of the construction to suffer - can the team suggest something I might try to minimise leakage as a temporary measure until I get a round tuit in the New Year? Thanks J^n |

Thanks J^n Bitumen (in solvent) and a piece of roofing felt. Or just bitumen, any cloth, and more bitumen NT |

Thanks J^n From your description, it sounds as if the flashing -- the few inches of felt that bend up the wall -- has cracked or peeled off. So cover it with flashing tape: Think grown-up sellotape where the tape is metal foil or metallic-looking plastic and the sticky stuff is bitumen or similar. Rub it well down with a wodge of rags. In this weather, warming it a bit might be a good idea. It works very well, and with luck you can leave off the tuit hunt for several years. If you see any actual holes in the felt, you can use the same stuff like a band-aid. Chris |

it has to have been dry for while before you try this though as I know to my
cost with a shed a few years back. Brian -- From the Bed of Brian Gaff. The email is valid as Blind user. wrote in message ...

Some of them can be applied even in puddles/under water and still sticks. Expensive though. |

Wickes sell tins of 'trowel on' emergency bitumen mastic roof repair. Works a treat, although you may have to sit it in a bucket of hot water for a while at this time of year before using it.

Temporary repair for felted flat roof leakage?
Hi All
thanks a lot for the useful suggestions. I wasn't sure how much of a bodge Flashband was supposed to be, nor how functional. I am now armed with some flashband and primer-type sticky stuff. When it stops p*ssing down for more than a few minutes I will have a go at drying things off and applying all of this. I've also spotted that the gutter above needs cleaning, despite me doing it only six months or so ago. That won't help matters... Thanks again Jon N |
