I moved into a house that has decking built right up to the (first floor) entrance area, which is above a flat roof. The wall plate is another piece of decking, attached directly to the brick wall without any sort of membrane or proper damp protection.
When it rains, water collects on there and sits for long periods, with no way to escape from the grooves. It is causing a couple of damp patches on the internal wall near the door, causing paint to flake off.
At some point someone has used sealant at the ends between decking and wall, but I don't know if that helps or hinders.
Would it be a good solution to drill a couple of holes in some of the grooves of the first plank, near the wall? This is probably the main cause of the water getting into the brickwork and causing damage.
Thanks for reading.
