GUTTERS & DOWNPIPES
Gutters are sized from catchment area calculations and fixed to fascia at a minimum 1:500 fall. Downpipes are connected to the stormwater system; overflows must be designed to discharge away from the building.

FLASHING & WEATHERPROOFING
Flashings at every junction (roof-to-wall, window head, step flashings and valley gutters) must be installed correctly to prevent water ingress. This is the most common source of defect claims in residential construction.

ROOF SPACE INSULATION
Bulk insulation (glasswool batts or rigid board) is installed in the roof space before the ceiling goes in. R-values must meet NatHERS design requirements; undersupply here affects thermal performance and the star rating.

GARAGE DOORS
Garage door frames, tracks and panels are installed and balanced. Lintel sizes, headroom clearance and torsion spring ratings must match the door size and weight; incorrect spring sizing is a common safety issue.
