How we approach dome rooflights in Corby
Thinking about dome rooflights in Corby? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Dome rooflights suit older flat roofs with yellowed or leaking domes.
From Corby to Uppingham, Kettering and Oundle, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Corby
- Polycarbonate or acrylic
- Clear, opal or tinted
- Twin, triple or quad skin
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Quick replacement on existing upstands
- Suits schools, flats and commercial roofs
What to check first
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Corby
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.
Read the planning permission guide before you commit to a design.

Common questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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.
Do I need to be at home for the survey in Corby?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Do you fit dome rooflights in Corby?
Yes. We survey and fit dome rooflights in Corby and across Northamptonshire. Send your postcode and we will offer a survey date when we reply.
