How we approach flat rooflights in Cramlington
We handle flat rooflights across Northumberland, including Cramlington. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
Cramlington sits about 7 km from Blyth and 10 km from Gosforth, and we cover the whole NE23 postcode district and the roads in between.
Choices for your Cramlington project
- Square, rectangular or long-format sizes
- Integral or fitted blinds
- Double or triple glazing
- Rain sensor if paired with an opening unit
- Frame colours: anthracite, black, white or RAL
- Pairs with an opening unit where you also need ventilation
- Even, top-down daylight across the whole room
Things we check at survey
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Consents for flat rooflights in Cramlington
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about flat rooflights in Cramlington
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
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.
Do you fit flat rooflights in Cramlington?
Yes. We survey and fit flat rooflights in Cramlington and across Northumberland. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Cramlington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
