Mortar? coming loose under slate roof on garage - Fix or leave alone?
Posted: Sun Nov 13, 2022 11:55 am
My garage has a vaulted roof with some old, fairly fragile slate on it. Under the slate, along each rafter there appears to have been something (mortar?) which I'm assuming was used to keep the slate in place. Most of it has come loose and fallen off (see picture).
Should I:
A) leave it alone. It must have started coming loose years ago and the slate is still in place. This way I also avoid the risk of damaging the slate in the process
OR
B) Replace it to give the slate a better chance of lasting? If so what should I use and how?
Thanks
