What do flat rooflights in Whitefield involve?
Flat rooflights in Whitefield means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the M45 district and the rest of Greater Manchester, with a survey before any price is fixed.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
We work across Greater Manchester, including Whitefield, and in neighbouring towns such as Radcliffe and Prestwich. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Plastered or lined internal reveal
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
Before you order: points to check
- 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
Do you need permission in Whitefield?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
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.
