Pitched roof windows for Dumbarton: the essentials
We handle pitched roof windows across Glasgow and Dunbartonshire, including Dumbarton. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Tenements and flats are common in Scottish towns and cities, where rooflights over stairwells and top-floor flats need the owners' and factor's agreement. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
We work across Glasgow and Dunbartonshire, including Dumbarton, and in neighbouring towns such as Erskine and Clydebank. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Dumbarton
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
How do I book a survey in Dumbarton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Dumbarton?
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas.
