Walk-on rooflights in Alnwick: what is involved?
We handle walk-on rooflights across Northumberland, including Alnwick. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Coastal exposure along the North East means we look closely at frame finishes and seals. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
We work across Northumberland, including Alnwick, and in neighbouring towns such as Morpeth and Ashington. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Alnwick project
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane
- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface
- Flush with paving or decking — no trip edge
- Pairs with a sliding box unit for terrace access
What to check first
- Drainage around the unit needs planning so water does not pond on the glass
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Consents for walk-on rooflights in Alnwick
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Common questions
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
How much weight can a walk-on rooflight take?
It depends on the model and size. Manufacturers state a design imposed load for each unit; we only specify a unit whose rating suits the use, such as a private terrace or a busier area.

Yes. We survey and fit walk-on rooflights in Alnwick and across Northumberland. Send your postcode and we will offer a survey date when we reply.
