About ONTRA
A family company
that obsesses
over detail.
Our story
Built different.
ONTRA was founded on a simple idea: roofs deserve the same care that goes into the rest of a building. Too often the roof is the afterthought, the part you don't see, until something goes wrong.
We're a family-owned business servicing all of metropolitan Sydney, with two decades of trade experience behind us and a deliberately small bench of tradespeople who all share the same standard. No subcontracting. No corner-cutting.
Every roof, every gutter, every flashing is detailed, fabricated and installed by people whose names are on the company.
We believe communication matters. Safety matters. Quality matters. People matter.
