Sliding rooflights in Weymouth: what is involved?
For Weymouth homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Neighbouring towns include Dorchester (12 km) and Bridport (25 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Weymouth
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. 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.

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.
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Will I need planning permission in Weymouth?
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.
Is the survey in Weymouth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
