How we approach bespoke & shaped rooflights in Dulwich
We handle bespoke & shaped rooflights across Greater London, including Dulwich. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for bespoke & shaped rooflights include openings that standard sizes do not fit.
Neighbouring towns include Brixton (2 km) and Peckham (3 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Dulwich
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
