Hi guys.
I've built a single storey side extension (300mm cavity wall) to a property I'm developing. The boundary isn't square and as such the front wall measures 2635mm to outside of wall plate, the back measuring 2282 to wall plate. It is 6m long.
I was going to do a warm flat roof with parapet front and back, however I have had a local truss company come up with 2 different ideas.
One is where all the mono truss rafters are built the same and as you progress to the rear of the extension (the shorter end) you would have to cut the ends of the trusses off back to the facing brickwork. This would mean you'd have to have a fairly large fascia to hide the ends.
An alternative they proposed is each individual truss is at a different pitch, means the ridge height and eaces height remain constant - however going from 17.5* pitch at the front to a 19.4* pitch at the rear. My concern is can this slight twist be accommodated within the roof tiling? Has anyone successfully done something similar before?
Would I be better off sticking with the flat roof design?
Both options attached and 3d model of the differing pitch option linked below.
3D model is here: https://www.mitek.co.uk/mitek3d/?3d_id=0b659f58-7067-4fd9-9f6d-dd6dbc18f46c
Any advice much appreciated!!
