How we approach dome rooflights in Banstead
Thinking about dome rooflights in Banstead? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
From Banstead to Ewell, Epsom and Coulsdon, the same survey-first process applies: measure, specify, fix the price, then fit.

Building control and safety duties in Banstead
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.

Questions about dome rooflights in Banstead
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.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Do I need to be at home for the survey in Banstead?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Banstead?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
