Since having a garage built & rendered I have been plagued with dampness getting in at the point where the roof & the concrete blocks meet. There is a small parapet on top of the front facing garage wall built I presume to make the garage look good from the front & to hide the roof from the front. This is the point where the damp gets in. I have been concentrating on the felt etc here but am beginning to think that I am on the wrong track. It has just struck me that the copings could be the problem. They are 5.5 inch copings & with the 4 inch blocks & the rendering on the garage walls the copes have virtually no overhang. I have phoned the local builders merchant looking for 8 inch copes but he says next size up is 11 inches which is obviously too big. Has anyone else had this problem? What did you do to solve it.

If longer copes is the solution buy 11" - hire a disc cutter and shorten them to suit.
Maybe there's a local firm specialising in brick & tile cutting - I recall seeing one such firm in the midlands - Atherstone, I beleive
I had thought of that but I don't know if cutting a coping would make the cut edge porous, which wouldn't help with my problem.
get the manufacturers name and contact them - they'll tell you if it is advisable. For instance Marley offer huge amounts of technical advice both for the builder and the novice.
