Why people pick a flat roof patio

  • The simplest buildNo ridge, and the sheets all run one way. It is the profile most first-timers finish in a weekend.
  • Fits under a low eaveIt sits lower than a gable of the same depth, which is often what decides it.
  • A clean line off the houseOn a rendered or flat-fronted home it reads as an extension rather than an addition.

Flat roof patio questions

01Does a flat roof patio actually keep rain off?

Yes. The sheets are sealed Colorbond with a fall on them, so water runs off rather than through. That is the difference between a patio and a pergola, which has open battens.

02Will a flat roof patio make my rooms dark?

It can, and the deeper it is the more it will. If the room behind it is one you sit in, keep the depth down or look at a gable, which holds more height at the front.

03Is a flat roof patio easier to build?

It is the most straightforward of the three. No ridge to set out and the roof sheets all run the same way, so most of the work is bolting rather than measuring.

04How much fall does it need?

Enough to shed water rather than pond on the sheets. It is set when the kit is cut, from the depth of the span and the height you need at the outer edge.
