How we approach dome rooflights in Deal
Our dome rooflights service in Deal 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Deal, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Deal sits about 13 km from Dover and 13 km from Ramsgate, and we cover the whole CT14 postcode district and the roads in between.
What you can choose
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fall-through protection mesh
- Polycarbonate or acrylic
- Clear, opal or tinted
- Suits schools, flats and commercial roofs

Before you order: points to check
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Deal
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.

Dome rooflights in Deal: 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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
How do I book a survey in Deal?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Deal?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
