What do flat rooflights in Wilmslow involve?
We handle flat rooflights across Cheshire, including Wilmslow. 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Wilmslow, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
From Wilmslow to Cheadle Hulme, Hazel Grove and Altrincham, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Wilmslow project
- Solar-control or self-cleaning outer pane
- Plastered or lined internal reveal
- Rain sensor if paired with an opening unit
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Slim sightlines from inside — mostly glass, little frame
- Inner pane laminated for safety overhead
Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Wilmslow
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Is the survey in Wilmslow free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Wilmslow?
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.
