Which rooflight suits the flat roof over a back kitchen-diner?
Where a semi has been extended at the back, the flat roof over the new room is where daylight can come from. The deciding questions are about the room. Do you cook there? Is there a table in the middle? Is the room narrow or wide?
A low pane for a narrow room
A flat rooflight stands on a shallow upstand and suits a narrow room or a galley kitchen. From the garden it is tidy, and the glass can be wiped from a ladder. Fitted as an opening model, it lets steam out from a switch on the wall. A guide to choosing for a flat roof sets out the options.
Height for a wide room
A lantern rises from the roof with glazed sides and gives a wider room height and more sky. It suits a table under it. The outside has more edges to clean, and the summer sun through it can be strong, so a blind or solar control glass is worth discussing. The page on lantern sizes and kerbs explains what the roof needs to carry one.
Cooking and the lid on the room
With a rooflight over the hob end of a kitchen-diner, steam rises straight to the glass and can mist it. An opening model clears that quickly, and a fixed one needs the room's other windows or an extractor to do the job. Think about how you cook before you choose.
Heat and glare at the table
A kitchen-diner with a glass roof can be bright and warm on a sunny day. A blind on the inside takes the glare off a laptop or a plate, and solar control glass cuts the heat that comes through. If the room faces the garden, think about where the sun lands at midday. We sit in the room at the survey and look at it with you.
Check the roof first
Before any cutting we look at the felt or other covering the rooflight will sit in, and the page on upstands and coverings explains what matters there. The planning guide sets out the position for a rooflight on a house, and we confirm what applies at your address.
In a kitchen-diner
Sit at the table and look up. If the sky should be above you, think lantern. If the room is narrow, think flat.
