Flat rooflights in Felling: what is involved?
Thinking about flat rooflights in Felling? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Coastal exposure along the North East means we look closely at frame finishes and seals. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Felling sits about 2 km from Gateshead and 4 km from Newcastle upon Tyne, and we cover the whole NE10 postcode district and the roads in between.
What you can choose
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Plastered or lined internal reveal
- Even, top-down daylight across the whole room
- Slim sightlines from inside — mostly glass, little frame
What to check first
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Planning and building rules for Felling
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Questions about flat rooflights in Felling
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
How do I book a survey in Felling?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Felling?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
