Skylights & Roof Glazing

Daylight from above is worth roughly three times the same window in a wall, and it reaches rooms nothing else can. The catch is that a hole in the roof is only ever as good as its flashing.

Getting the light without the heat

An unglazed-for-climate skylight in a west-facing Sydney roof turns a room into a greenhouse by 3pm. The glass specification is what prevents that.

  • Low-E coatings. A microscopically thin metallic layer that lets visible light through while reflecting a large share of the infrared. The single most effective choice you make.
  • Double glazing. Two panes with a sealed cavity. Cuts heat transfer in both directions and largely eliminates the winter condensation that drips off single-glazed units.
  • Laminated inner pane. Required for overhead glazing so that nothing can fall through if the glass is ever broken. It also filters essentially all UV, which protects flooring and furniture.
  • Tints and diffusers. Grey and bronze tints cut glare; a diffusing interlayer spreads light evenly instead of throwing a hard bright rectangle across the floor.

Fixed, openable, and where they go

Fixed units are simpler, cheaper and have fewer things to fail. Openable units earn their cost in rooms that need to vent — bathrooms, kitchens, and stairwells that trap hot air at the top.

  • Pitched roofs take a unit in the plane of the roof, flashed into the tiles or sheeting with a purpose-made kit.
  • Flat roofs need either a fall built into the unit or a kerb, so water runs off rather than pooling on the glass.
  • Shafts matter. On a two-storey house or a deep roof space, the shaft between roof and ceiling does as much for the light as the glass. A splayed shaft throws noticeably more light into the room than a straight one.
  • Rain sensors and motors on openable units close them automatically. Worth it on anything you cannot easily reach.

Questions

Skylights & Roof Glazing — the usual questions

Will a skylight leak?

Not if it is flashed correctly. Almost every leaking skylight we are called to has either a site-made flashing or a kit fitted to the wrong roof profile. We use the manufacturer kit matched to your roof.

Can I put one in a bathroom?

It's one of the best places for one — daylight and ventilation in a room that usually has neither. An openable unit with a rain sensor is the usual choice.

How much light will it actually give?

Considerably more than a wall window of the same area, because it sees the whole sky rather than a slice of it. The shaft shape between the roof and the ceiling makes a big difference to how evenly it spreads.

Do I need council approval?

For a straightforward replacement or a new skylight in an existing roof, usually not. Heritage listings and strata buildings are the exceptions — check before you order.
