How we approach dome rooflights in Weymouth
Dome rooflights in Weymouth means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the DT4 district and the rest of Dorset, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Jobs in Weymouth 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.
Choices for your Weymouth project
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Twin, triple or quad skin
- Suits schools, flats and commercial roofs
- Light, impact-resistant domes
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Regulations for dome rooflights in Weymouth
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.
Read the planning permission guide before you commit to a design.

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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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 work alongside my builder in Weymouth?
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 Weymouth?
Yes. We survey and fit dome rooflights in Weymouth and across Dorset. Send your postcode and we will offer a survey date when we reply.
