Flat rooflights in Market Harborough: what is involved?
We handle flat rooflights across Leicestershire, including Market Harborough. 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.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. In Market Harborough, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Jobs in Market Harborough are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Plastered or lined internal reveal
- Rain sensor if paired with an opening unit
- Slim sightlines from inside — mostly glass, little frame
- Even, top-down daylight across the whole room
Things we check at survey
- New openings in an existing roof need a structural check on joists
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Consents for flat rooflights in Market Harborough
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. 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.

Flat rooflights in Market Harborough: questions
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.
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.
How do I book a survey in Market Harborough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Market Harborough?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
