Carports in Perth
Flat roof carports
Flat roof carports run a low-profile, near-horizontal roofline that reads as contemporary and clean from the street. They aren't actually flat, we run a 2 to 3 degree slope for drainage, but visually they read as flat. The go-to choice for modern rendered facades and minimalist new builds.

Flat roof carports in Perth
Low-profile carports for modern homes
Flat-roof carports read as visually flat from the street while running a slight pitch underneath for drainage. The right pairing for modern minimalist homes with rendered facades or parapet rooflines.
Drainage is the make-or-break detail. Gutter sizing and downpipe spec matter more than the cladding gauge on a flat-roof build.
