How we approach dome rooflights in Skelmersdale
Thinking about dome rooflights in Skelmersdale? 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
We work across Lancashire, including Skelmersdale, and in neighbouring towns such as Ormskirk and Wigan. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Skelmersdale
- Twin, triple or quad skin

Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass

Rules and responsibilities in Skelmersdale
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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 work alongside my builder in Skelmersdale?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Skelmersdale?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
