Dome rooflights for Windsor: the essentials
Thinking about dome rooflights in Windsor? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Dome rooflights suit schools, flats and commercial flat roofs.
Neighbouring towns include Slough (3 km) and Egham (7 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Windsor
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. Fragile-roof safety and access are planned before work starts.
Our planning guide covers each nation in more detail.

Dome rooflights in Windsor: questions
Can domes open?
Hinged and vented domes are available, manual or electric.
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.
How do I book a survey in Windsor?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Windsor?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
