How we approach dome rooflights in March
We handle dome rooflights across Cambridgeshire, including March. 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
March sits about 14 km from Wisbech and 21 km from Ely, and we cover the whole PE15 postcode district and the roads in between.
Options we can specify in March
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Polycarbonate or acrylic
- Clear, opal or tinted
- Fixed or hinged with vent
- Light, impact-resistant domes
- Smoke-vent versions available
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Regulations for dome rooflights in March
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in March
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.
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 you fit dome rooflights in March?
Yes. We survey and fit dome rooflights in March and across Cambridgeshire. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in March?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
