Dome rooflights for Harlow: the essentials
Thinking about dome rooflights in Harlow? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Harlow is around 49 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the CM17 district.
Choices for your Harlow project
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Suits schools, flats and commercial roofs
- Fixed, hinged or vented options
Before you order: points to check
- Upstand condition decides whether you replace dome only or the whole unit
- Fire classification matters on some roofs
Regulations for dome rooflights in Harlow
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.

Dome rooflights in Harlow: questions
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 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.
Can you work alongside my builder in Harlow?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit dome rooflights in Harlow?
Yes. We survey and fit dome rooflights in Harlow and across Essex. Send your postcode and we will offer a survey date when we reply.
