How we approach sliding rooflights in Westhoughton
Thinking about sliding rooflights in Westhoughton? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Sliding rooflights suit walk-out access where a hatch would feel cramped.
We work across Greater Manchester, including Westhoughton, and in neighbouring towns such as Atherton and Hindley. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Anthracite, black or RAL frames

Before you order: points to check
- Needs space on the roof for the lid to slide clear
- Weight and point loads need a structural check
Do you need permission in Westhoughton?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Sliding rooflights in Westhoughton: questions
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
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.
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.
Will I need planning permission in Westhoughton?
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.
Do I need to be at home for the survey in Westhoughton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
