Flat rooflights for Stockport: the essentials
We handle flat rooflights across Greater Manchester, including Stockport. 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.
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. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
Neighbouring towns include Hazel Grove (4 km) and Cheadle Hulme (4 km). We offer a survey date when we reply to your enquiry.
Choices for your Stockport project
- Square, rectangular or long-format sizes
- Double or triple glazing
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Plastered or lined internal reveal
- 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
- The roof membrane must be dressed up the upstand before the unit goes on
Do you need permission in Stockport?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Read the planning permission guide before you commit to a design.

Flat rooflights in Stockport: questions
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.
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 Stockport?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Stockport free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
