Bay window flat Roof

[Basecoat]

Hi All

Back again to seek advice. My bedroom bay window having flat roof has a leak. Luckily my other half spotted it and put a container under it to catch the drips. I couldn't get near it for the snow.

Yesterday I got chance to check the leak. I have done a temporary repair but I would like to do a lasting repair. I have lead flashing covering area approximately 10 feet x 4 feet. The lead is in one piece.

I don't think I could get a lead flashing to cover a big area these days. My house was build pre war. Lead must have been ideal material as well as cheap to use at that time.

What alternative material there is I could use. Positive feed back as always will be highly appreciated. Thanks in advance.

is the lead punctured or just come loose?

Hi. The sheet lead covering you describe has probably failed due to the length that has been fitted. It is usual to break the roof up into sections, thus reducing the expansion and contraction which causes metal fatigue and leaks, this is done with wood core roll which is in effect an expansion joint. It may well be possible to contract a lead worker to alter the situation to accommodate such. That is using existing lead sheet. Good Luck

Hi "badgercheif"

The lead has had some holes in and have been bodged I guess. I would like to do a effective lasting repair. Any suggestions.

Hi "justlead1"

You are absolutely right about the "wood Roll". To be honest I didn't know why this thing has been there. This wood roll isn't on neighbours bay roof. Is there anything I can do or is it I need a lead person.

Can you post a picture basecoat? it always makes for more accurate diagnosis and advice.

to be honest from what i can gather from your posts then getting a lead man would one of the more expensive ways of repairing this problem. lead is although recently the price has been falling expensive against materials such as a built up felt system and if you got a decent felt roofer in he would be able to use the lead as a flashing detail to the upstands in the felt system. get a felt round and ask him for a quote and give me shout if you want ill be able to tell you if its a fair price or not
