What do dome rooflights in Crouch End involve?
We handle dome rooflights across Greater London, including Crouch End. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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 schools, flats and commercial flat roofs.
We work across Greater London, including Crouch End, and in neighbouring towns such as Muswell Hill and Wood Green. Access, parking and how the glass reaches the roof are all checked at the survey.

Regulations for dome rooflights in Crouch End
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Crouch End
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 you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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 Crouch End?
