Hi,
I have an extension near finished that has a flat roof, with a (3) flat roof window.
The roof has an angle of about 5 degrees in which the rain water runs away, but the roof windows have one of about 1 degree. The problem with this is the water stagnates and when dries leaves unsightly ring marks (from the 'rubbish' in London rain water!).
My builder says that these have been installed correctly, but I'm not so sure.
Can anyone help?
Thanks
