Hello. This is my first time on diy doctor so bare with me.
I am currently constructing/rebuilding lean to roof to conservatory. I am replacing it with tiled roof with roof windows. dim 2.5m x 4m. I am wondering what is the best type of bolts to use when securing the wall plate to the external wall. There is already a 50mm wall plate on the wall and it is secured with screws but i know that is not satisfactory. Any ideas?
