How we approach sliding rooflights in Stockport
Our sliding rooflights service in Stockport covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
From Stockport to Hazel Grove, Cheadle Hulme and Denton, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Double or triple glazing
- Rain sensor
- Electric drive with safety edge
- Full-width, walk-out access to a roof terrace
- Replaces a dormer or stair enclosure on some roofs
What to check first
- Needs space on the roof for the lid to slide clear
- Electric units need a dedicated supply and commissioning
Planning, building control and 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.
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.

Common questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Can you work alongside my builder in Stockport?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
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.
