If you don't mind me asking , what type of mortar joints have you used and what roof colour have you chose ?
Did you use sarking ? Is sarking really expensive?
Yeah sure no problem.
The mortar joints are the Ironed type in the off-white colour. These were standard inclusions, so no extra costs.
The Colorbond roof colour is Shale Grey. And we upgraded to the R1.3 Foil-Backed 55mm Building Blanket. This upgrade cost $3400 extra.
