What do dome rooflights in Plymouth involve?
Our dome rooflights service in Plymouth covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
We cover all of Plymouth and the PL1 district, and nearby Plymstock and Paignton.
Options we can specify in Plymouth
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Twin, triple or quad skin
- Fall-through protection mesh
- Fixed or hinged with vent
- Suits schools, flats and commercial roofs
- Quick replacement on existing upstands
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Plymouth
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. 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.
Our planning guide covers each nation in more detail.

Dome rooflights in Plymouth: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do I need to be at home for the survey in Plymouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.

Yes. We survey and fit dome rooflights in Plymouth and across Devon. Send your postcode and we will offer a survey date when we reply.
