Sliding rooflights in Melksham: what is involved?
Our sliding rooflights service in Melksham 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Melksham is around 32 km from Swindon, and we survey and fit throughout that part of Wiltshire, including the SN12 district.

Planning, building control and Melksham
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
