Rooflights and clear roofing sheets
Rooflights let daylight into a building through the roof itself. Profiled rooflights are made to the same shape as the roof sheets, so they sit in the run of the roof in place of a steel sheet. Tell us the roof and we'll match the rooflight, and send it with the sheets.
- Matched to your sheet or panel profile
- GRP or polycarbonate
- Single, double or triple skin

Clear roofing sheets
Clear sheets that match the profile of the roof.
Choosing rooflights
How profiled rooflights work
A profiled rooflight is a translucent sheet made to the same profile as the steel sheets around it: 32/1000 box profile, corrugated or the outer face of an insulated panel. It laps into the roof like any other sheet, so the roof stays one continuous, weathertight surface.
Matching an existing roof? Measure the old sheet (the rib height, the distance between ribs and the cover width) or send us a photo of the end of the sheet, and we'll find the rooflight that fits.
Single, double or triple skin
On a roof that isn't insulated, such as a barn, store or garage, a single-skin rooflight goes in with the single-skin sheets.
On an insulated roof, the rooflight has to keep the heat in too. That means a double or triple-skin rooflight, either built up on site with a spacer between the skins, or a factory-assembled insulated rooflight that arrives as one sealed unit. We'll match it to your built-up system or insulated panels.
GRP or polycarbonate
GRP (glass-reinforced polyester) is the usual choice on industrial and agricultural roofs: it's tough, spreads the light evenly without glare, and comes in grades for buildings with fire requirements.
Polycarbonate is very clear, light and has high impact strength, which makes it popular on carports, lean-tos, canopies and smaller buildings.
How much light, and where
As a guide, rooflights often cover around 10 to 15% of the roof on an industrial building, spread evenly so the light falls evenly across the floor. The right amount depends on what the building is used for and its energy calculation, so tell us and we'll help you plan it.
Safety on the roof
Rooflights can be fragile. Where people will work on or near them, ask for rooflights tested as non-fragile to ACR[M]001, and fit safety mesh or guarding where the specification asks for it. Tell us how the roof will be accessed and we'll quote accordingly.
How to order
Send us the sheet profile, the length and how many rooflights you need, and whether the roof is insulated. Rooflights need their own fixings (with larger washers, fixed through oversized holes so the sheet can move) and sealant on the laps; we'll include them with the order.
Questions we’re asked
What is a roof light?
On a metal roof, a profiled rooflight is a translucent sheet made to the same profile as the steel sheets, so it fits straight into the run of the roof and lets daylight in.
What sizes do rooflights come in?
Profiled rooflights match the profile and cover width of your roof sheets, and come in the lengths you need.
