My daughter has purchased a house with a sectional garage, I think the
make is Compton. Anyway, it gets into the garage three ways.
1) Through the sides of the door.
2) Past some roof nails (these have rubber "top hats" on).
3) The most by water running off the roof at the rear of the garage then
into the gap between the corrugated roof and wall.
Any suggestions please as how best to deal with this?
Many thanks
