Looking for some information. Currently have a garage converted into an office but it wasn't done well. Time has come to replace the flat roof properly, I want to put an insulated warm roof on instead of the felt shed roof it currently has.
Garage is attached to the house and is single skin brick built with piers, was wondering about raising the joists about six inches to provide more headroom. I would need a plate fastened to the brick outer wall of the house for the joists to hang off. Existing joists are set into brickwork so would be cut back, could sit plate on that and still bolt it. Could this just be bolted with M12 sleeve bolts and could six inches of timber be fastened to the top of the existing walls for the joists to be fastened to? This would create the height I need.
Brickwork was done in the 70's and all appears to be in good order. Should I be worried about the weight compared to the roof that is already there?
