Dome rooflights for Bridport: the essentials
We handle dome rooflights across Dorset, including Bridport. 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Jobs in Bridport are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Fixed or hinged with vent
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Suits schools, flats and commercial roofs
- Fixed, hinged or vented options
Things we check at survey
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Bridport
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Bridport
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.
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 Bridport?
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 Bridport?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
