How we approach dome rooflights in Whitehaven
Thinking about dome rooflights in Whitehaven? 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
From Whitehaven to Workington, Keswick and Ulverston, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Clear, opal or tinted
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Polycarbonate or acrylic
- Quick replacement on existing upstands
- Low cost per unit
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Whitehaven
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. 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. Fire classification of rooflight materials near boundaries is checked at specification.

Dome rooflights in Whitehaven: questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
