What do pitched roof windows in Hayes involve?
For Hayes homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of pitched roof windows for lofts, attic rooms, landings and vaulted ceilings.
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.
Options we can specify in Hayes
- Integral blinds and shutters
- Manual, electric or solar-powered opening
- Flashings for tiles, slates or recessed fitting
- Double or triple glazing
- Combination and stacked windows
- Fits between rafters in most roofs
- Daylight and ventilation in a pitched roof
What to check first
- Escape-window rules can apply to loft rooms
- Front-facing roof windows can need permission in conservation areas
Consents for pitched roof windows in Hayes
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. 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.
