bowing new roof!!! Information, help and tips on many areas of roofing including trusses, tiling, venting, insulation etc....

[rose]

have had a new flat top roof with 3 pitched sides put on extension but for
some reason when u look on sideways there seems to be a bow in it.

What could be the reason for this?

thanks for help

rose,
Assuming you are referring to looking at the drip edge of the flat roof you should expect a slight dip towards the middle to encourage water away for the three enclosed sides.
