What do bespoke & shaped rooflights in Prestwich involve?
Bespoke & shaped rooflights in Prestwich means triangular, angled, curved and multi-pane rooflights made to measure. We cover the M25 district and the rest of Greater Manchester, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for bespoke & shaped rooflights include openings that standard sizes do not fit.

Planning, building control and Prestwich
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. 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.

Common questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Do I need to be at home for the survey in Prestwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Prestwich?
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.
