Dome rooflights for Welling: the essentials
Our dome rooflights service in Welling covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Neighbouring towns include Bexleyheath (2 km) and Bexley (4 km). We offer a survey date when we reply to your enquiry.

Rules and responsibilities in Welling
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Welling: questions
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
How do I book a survey in Welling?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Welling?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
