We are replacing an old 6m x 4m felt roof on a rear single storey extension with EPDM and taking the opportunity to install a rooflight 1m x 2m. Bigger would be nicer but being cautious with the joists, weight-load etc. There is a small pitch but it is only 3-4 degrees at steepest point.
Researching Options as follows
1. Rooflight Panoroof style, where you silicone the glass unit straight on to timber frame from £600 upwards - Panoroof on eBay £799. Lowest initial cost and easiest for roofer to fit, but hard and costly to change if unit fails.
2. Rooflight with aluminium frame from £1050. Atlas brand £1173. Roof maker brand £1694. Easy for roofer to fit. Can change unit if it fails.
Both - a large heavy item to take delivery of. Shallow roof pitch means self cleaning glass will struggle to do much. I prefer the external look, as to me it is more 'modern' than a lantern.
3. Roof Lanterns - Korniche brand £1000, Atlas £1375, Keylite £1475. And a lot more if you want. Shallow pitch means should be fine. A bit harder to fit but easier to take delivery off as comes in kit. Will add a feeling of space as ceiling is low in the extension. Let's more light in apparently as more glass (??). Self cleaning glass should work decently. Not as 'clean' a look when looking out over the roof from bedrooms.
Thoughts - Given cost of the Korniche lanterns they seem the way to go for us, unless anyone has any particular negative advice to the contrary either about lanterns or the Korniche brand.
As ever thanks for any input. Just writing it all down helps haha.
