Installation checklist

Use competent roofing contractors and follow the Brett Martin installation guide.
Carry out a suitable risk assessment and fall-protection plan before work begins.
Install onto a fully insulated and weathered builder’s upstand.
Ensure the roof covering dresses up the sides and over the top of the upstand.
Provide a level, obstruction-free bearing surface for the roof lantern.

Important safety note

Roof lanterns and rooflights should be considered fragile during installation. Suitable fall-protection measures should be defined in line with CDM regulations and Rooflight Association guidance.

Where blinds or other fittings are installed in the lightwell, position them as far as practicable from the glass and preferably choose light colours to help reduce thermal stress risk.

Laminated vs toughened inner panes

Toughened inner pane Standard option for roof lantern installations where toughened safety glass is suitable.
Laminated inner pane Helps hold the glass together if damaged, reducing the risk of glass falling into the space below.
Project assessment Glass choice should be considered against the project location, use and relevant guidance.
