Dome rooflights in Borehamwood: what is involved?
Dome rooflights in Borehamwood means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the WD6 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 Borehamwood, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Borehamwood sits about 5 km from Barnet and 6 km from Bushey, and we cover the whole WD6 postcode district and the roads in between.

Regulations for dome rooflights in Borehamwood
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 Borehamwood
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you work alongside my builder in Borehamwood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
