Case Study

Flat Sheeted Roof with a Lined Soffit — Lanseria

No adjustable blades on this one. A flat sheeted roof, lined underneath — the simplest thing we build, and the right answer for a deck this exposed.

Location: Lanseria  ·  System: Fixed Patio Roof + Boarded Ceiling

Charcoal-framed flat patio roof with a lined soffit over a raised deck near Lanseria

The brief

A modern house outside Lanseria, with a raised deck running along one elevation behind a horizontal-rail balustrade and trees beyond it.

A deck this exposed takes weather from every direction, and what it needs is shelter that is permanently reliable rather than a roof with moving parts to think about.

What we built

A charcoal-framed flat roof carried on posts at the deck edge, sheeted above and lined below with a flat soffit in a light colour.

The lining is the point. A sheeted roof left open underneath shows its own underside, its purlins and every fixing. Closing it in gives a flat plane over the deck and makes the space read as an outdoor room.

The system itself is set out under our full awning range, and there is more of our work in Fourways & Dainfern.

When fixed beats adjustable

We build more adjustable louvre roofs than anything else, and they are not always the right answer. On an exposed site used mainly for shelter, a fixed roof is simpler, quieter in wind, and has nothing that needs operating.

The trade is real and worth stating plainly: you give up the winter sun a louvre roof lets in. Where the deck already has open sky on three sides, that matters much less than it would on an enclosed patio.

The specification behind it

  • Fixed aluminium patio roof, charcoal frame, sheeted above
  • Flat lined soffit to the underside in a light finish
  • Posts at the deck edge, clear of the balustrade line
  • Gutter integrated into the frame, with the downpipe run down the outside
  • 15-year guarantee on aluminium, 10-year on Chromadek®

The honest version of this project

This job sat in our own archive filed as a louvre. It is not one — there are no adjustable blades anywhere on it, and anyone comparing quotes deserves to know which of the two they are looking at.

The distinction matters commercially as well as technically. A fixed sheeted roof and an adjustable louvre roof are different products at different prices, and the photographs of a finished job can look similar from the garden.

If you’re considering the same

If a quote and a photograph do not obviously agree, ask directly whether the blades adjust. It is the single biggest difference between two structures that photograph almost the same.

Compare the options across our full awning range.
