Flat rooflights for Swadlincote: the essentials
Flat rooflights in Swadlincote means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the DE11 district and the rest of Derbyshire, with a survey before any price is fixed.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Think of flat rooflights for kitchen extensions, side returns and flat-roofed back rooms.
Swadlincote is around 17 km from Derby, and we survey and fit throughout that part of Derbyshire, including the DE11 district.

Consents for flat rooflights in Swadlincote
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.

Common questions
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.
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.
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.
Do I need to be at home for the survey in Swadlincote?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Swadlincote?
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.
