I have a flat roof on a garage attached to the house. It has not been re-covered since it was buit in 1959, but has been repaired many times. I now feel that it is time to strip off the old covering completely and re-cover it.
I will need to be able to walk on it occasionally, mainly to drag a large canadian canoe, which I keep in the back garden, over to the front garden (there isn't room to carry it through the side passage).
Can anyone suggest the best covering for this purpose?
