What do dome rooflights in Watford involve?
Dome rooflights in Watford means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the WD17 district and the rest of Hertfordshire, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Watford, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Watford is the main town we list in Hertfordshire; we also cover nearby Bushey and Rickmansworth.

Before you order: points to check
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Watford
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
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.

Questions about dome rooflights in Watford
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can domes open?
Hinged and vented domes are available, manual or electric.
