How we approach bespoke & shaped rooflights in Dumbarton
We handle bespoke & shaped rooflights across Glasgow and Dunbartonshire, including Dumbarton. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Typical uses for bespoke & shaped rooflights include angled ceilings, corners and architect-designed extensions.
Dumbarton is around 21 km from Glasgow, and we survey and fit throughout that part of Glasgow and Dunbartonshire, including the G82 district.

Planning and building rules for Dumbarton
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
Read the planning permission guide before you commit to a design.

Questions about bespoke & shaped rooflights in Dumbarton
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
