Hi all,
Moved into a terraced house a couple of years ago with a lean-to extension at the back (which was built a number of years ago). There are roof windows for half of the extension that, when the rain gets bad, cause a slight leak inside the house from the external wall. There’s a box gutter behind the windows and, when that gets full (in particularly bad rain), the leak gets worse.
Last year’s solution was to put some waterproof tape over the end of the window which has significantly helped. To prep for this year, I was planning on replacing last year’s tape with some more heavy-duty butyl sealant tape, but thought I’d see if anyone could advise on best solution for sorting the problem before ordering the tape.
Thanks! Appreciate any advice!
