Dome rooflights for Denton: the essentials
Our dome rooflights service in Denton 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Denton, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
From Denton to Hyde, Dukinfield and Droylsden, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Denton project
- Clear, opal or tinted
- Twin, triple or quad skin
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Low cost per unit
- Quick replacement on existing upstands
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Old domes may be fragile — treat as fragile until checked
Regulations for dome rooflights in Denton
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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.
Read the planning permission guide before you commit to a design.

Dome rooflights in Denton: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
Do I need to be at home for the survey in Denton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Denton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
