Hi,

Water is coming through the edge of the wall and ceiling on an
external wall. There is a flat roof with felt that looks in decent
condition. I think the rain is coming through a crack in the roof felt
as it folds over the edge of the roof. Most of the rain water is going
into the gutter but some is running down the fascia board and I think
“creeping” back into the room.

Now the question is how do I fix it? I guess the area will be soaking
wet and will need to dry out. Also I need to fix the problem.

So how will I best get all this to dry out to avoid later fungi or
rot? How do I fix the crack in the edge of the roof felt? I have some
of that self-adhesive roll that is sticky on one side and metallic on
the other side. Will that adhere to the felt or come off? Is there
some “goo” I can put into the crack in the felt?

Thanks for any suggestions.

Clive
