Reviewed byZaib Khan
Updated onSeptember 2026

A glass roof on a medium Gable fronted conservatory typically costs £4,000 to £6,400, fitted.

Small£4,000£3,000 to £4,900
Medium£5,200£4,000 to £6,400
Large£6,600£5,100 to £8,000

A gable fronted conservatory has an upright triangular front instead of a sloping one, so the roof runs back to the house like a small pitched house roof. It gives the most headroom and light of any style.

Glass roofs on a Gable fronted conservatory

Gable glass roofs are tall and bright. Solar control glass is close to essential on a south facing gable.

  • The triangular gable end is usually glazed. With a tiled roof it can stay glazed, be clad, or be filled with an insulated panel.
  • The pitched roof suits tiles well and looks like a proper extension from the garden.
  • Higher ridge heights can mean scaffolding rather than ladders, which adds cost.
