Dome rooflights for Melksham: the essentials
Dome rooflights in Melksham means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the SN12 district and the rest of Wiltshire, with a survey before any price is fixed.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Melksham, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We work across Wiltshire, including Melksham, and in neighbouring towns such as Trowbridge and Chippenham. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Fall-through protection mesh
- Clear, opal or tinted
- Fixed or hinged with vent
- Light, impact-resistant domes
- Suits schools, flats and commercial roofs
Before you order: points to check
- Old domes may be fragile — treat as fragile until checked
- Fire classification matters on some roofs
Building control and safety duties in Melksham
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. Fragile-roof safety and access are planned before work starts.

Common questions
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
