Dome rooflights for Marlborough: the essentials
Our dome rooflights service in Marlborough 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 work across Wiltshire, including Marlborough, and in neighbouring towns such as Swindon and Devizes. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Low cost per unit
- Smoke-vent versions available
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Building control and safety duties in Marlborough
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Dome rooflights in Marlborough: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
