Dome rooflights for Towcester: the essentials
For Towcester homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Neighbouring towns include Northampton (15 km) and Daventry (18 km). We offer a survey date when we reply to your enquiry.
Specification options
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Clear, opal or tinted
- Fall-through protection mesh
- Low cost per unit
- Light, impact-resistant domes
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Towcester
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 domes open?
Hinged and vented domes are available, manual or electric.
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 Towcester?
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 Towcester?
Yes. We survey and fit dome rooflights in Towcester and across Northamptonshire. Send your postcode and we will offer a survey date when we reply.
