Sliding rooflights in Hayes: what is involved?
We handle sliding rooflights across Greater London, including Hayes. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Jobs in Hayes are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Box (glazed sides) or flat sliding lid
- Anthracite, black or RAL frames
- Rain sensor
- Double or triple glazing
- Electric drive with safety edge
- Full-width, walk-out access to a roof terrace
- Glazed box sides keep the headroom open
Things we check at survey
- Electric units need a dedicated supply and commissioning
- Needs space on the roof for the lid to slide clear
Planning, building control and Hayes
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. 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. 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.
