What are hinged roof access rooflights?
Our hinged roof access rooflights service in Wiltshire covers hinged glazed hatches over a stair or ladder for roof terrace access. We survey every job before fixing the price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure.

Planning and building rules in England
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. 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.

| Gas-strut hatch with grab handle Typical | £3,955 – £5,395 | £3,295 – £4,495 |

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
Can it be opened from the roof?
Many units have an external handle or key for opening from outside. If you need that, tell us at survey.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
Do you fit hinged roof access rooflights across Wiltshire?
Yes. We survey and fit hinged roof access rooflights across Wiltshire, including Swindon, Salisbury, Trowbridge.
