I've got a roof with a few diagonal trusses like the blue one in this diagramme:
I want to remove the BLUE truss and replace it with the RED truss, because we're adding some loft storage and currently have to climb over the blue trusses to move around.
Three important notes:
- The right most vertical beam ends above a wall, whereas the proposed red beam would end only on the supporting beam.
- The truss supports lightweight roof sheeting in tin or aluminium. There's nothing else on the roof.
- I live in South Africa, where there's some wind and some rain, but no snow.
Is there anything very critical I should beware of, or should I avoid doing this entirely?
