Hi, looking for general opinions and options for my roof on my self build extension.
It was last year I did the plans and cant remember how I calculated the ridge beam size, and now I have installed it I am doubting myself.
Quick facts:-
Beam is 75mm x 225mm C24
Rafters are 47mm x 175mm C24 at 400 centres
Distance from from wall to beam is 2.8m each side
Pitch is a low 20 degrees.
Wanting a vaulted ceiling.
The extension is an 'L' shape, the beam runs 4m across from current building to new gable. The first two metres will actually act as a ridge plate as a lean to roof, it will be bolted even though the beam is supported BOTH ends on blocks to the foundations. This leaves the remaining 2m of ridge beam to hold the rest of the roof with rafters both sides.
Looking at forums the ridge beams seem much bigger, although this is quite a small extension. I could easily run a block pillar up the edge of the current build where the 'L' bends(centre of the ridge beam) from the foundations, thus supporting the ridge beam in the middle, so effectively the beam is spanning just 2m from new pillar to gable.
Worst case scenario, and SE decides its not enough, would it just be a matter of adding ceiling joists and doing away with the vaulted ceiling?
Many thanks in advance.
