Hi,
My garage door opening is somewhat too short and I am looking to raise it slightly.
It is currently restricted a supporting timber that runs across the top of the door with the roof joists (flat felted roof) rest directly on top of. I am wanting to remove this timber.
The joists are 150mm x 50mm and the timber over the door is 150mm x 75mm. My idea is to attach joist hangers flush up against the current 150mmx75mm timber and then temporarily support the roof somehow inside whilst I cut the joists flush and allow me to remove the supporting timber.
Then I would replace this by another 150mm x 75mm timber that is a few foot longer which I can attach the hangers too and would then rest on the top of the cut ends of the original 150mmx75mm timber either side of the garage door and then attach with something like stitch plates either side.
Hopefully my woefully poor diagram will help clarify.
Does this sound practical and is it sufficient to support the roof loading?
Thanks in advance!
