How we approach flat rooflights in Walkden
Our flat rooflights service in Walkden covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 Walkden, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Walkden sits about 4 km from Farnworth and 4 km from Swinton, and we cover the whole M28 postcode district and the roads in between.
Options we can specify in Walkden
- Square, rectangular or long-format sizes
- Plastered or lined internal reveal
- Integral or fitted blinds
- Double or triple glazing
- Solar-control or self-cleaning outer pane
- Even, top-down daylight across the whole room
- Slim sightlines from inside — mostly glass, little frame
What to check first
- The roof membrane must be dressed up the upstand before the unit goes on
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning and building rules for Walkden
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
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.
Is the survey in Walkden free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Walkden?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
