Leaking Bay Window

sbird90

Hi hope someone can help

i live in 1930s property, lived here almost two years. Today we had a storm with very heavy rainfall and I noticed water dripping through the top floor bedroom bay window. Bay window has a flat roof. I can see where the water is coming in, photo below. Does it just need rechalking? It’s never happened before so could it be due to the amount of water that’s fell in a short space of time not being able to drain away in time or do you think the bay roof needs investigating?

thanks to anyone who responds

Is it a felt covering or lead/zinc ?

Water will penetrate in one spot and then travel unseen before dripping out elsewhere. The point where the water is dripping isn't always where it is getting in.

It may pay to strip the flat roof off completely, repair any rotten timbers, and then insulate as much as you can. Once that is done, replace the felt with epdm, fibreglass, or lead/zinc - If you are in a conservation area, your hands may be tied with regards to the type of finish.

It would be helpful to put some external photos up. A roof shouldn't leak, however heavy the rainfall is.

You need someone to have a look at it unless you have ladders and can get up and take some external photos to post on here. If you don't know a roofer / builder then ask friends for recommendations - I'd never use any of the so called trader websites / google reviews as I believe many are faked. In my village and all the surrounding villages there are community facebook pages which can be good for recommendations.

I’m honestly not sure but think lead from what I can see. Will it need a roofer or a window fitter company?

Nah no ladder tall enough unfortunately, neighbour is a roofer I’ll have to ask them to take a look. Sighhh, just had them up on the roof the other day for a slipped slate tile (different party of the roof). One thing after another isn’t it!
