Which of these roof styles would YOU choose in a monsoon?
I live in the Northern Rivers – and let’s face it, the name says it all. This region of NSW is lush, green... and very wet. Torrential downpours aren't rare — they’re the rhythm of the seasons.
That makes your roof more than just a design feature — it’s your home’s umbrella. It’s job is to move water away fast and protect what’s underneath.
Now imagine using a flat umbrella in a storm... exactly.
Flat and low-pitched roofs can look sleek and modern, but they rely on engineered drainage systems and waterproofing that must work perfectly over the lifetime of your home. In high-rain areas, that’s a risky game.
Heavy rain can overwhelm these systems. One blockage or waterproofing failure and water has nowhere to go but inward — leading to leaks, mould, and building damage.
As architectural scientist Dr. Tim Law puts it: “There are two types of flat roofs: those that have leaked, and those that will leak.”
In wet climates, slope matters. Pitched roofs follow nature’s flow to stay dry and durable.
