How we approach dome rooflights in Caterham
Dome rooflights in Caterham means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the CR3 district and the rest of Surrey, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
We work across Surrey, including Caterham, and in neighbouring towns such as Coulsdon and Purley. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic

What to check first
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked

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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Do I need to be at home for the survey in Caterham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Caterham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
