What do bespoke & shaped rooflights in Watford involve?
Thinking about bespoke & shaped rooflights in Watford? The short answer: triangular, angled, curved and multi-pane rooflights made to measure. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for bespoke & shaped rooflights include angled ceilings, corners and architect-designed extensions.
We cover all of Watford and the WD17 district, and nearby Bushey and Rickmansworth.

Planning, building control and Watford
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Bespoke & shaped rooflights in Watford: questions
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
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.
