Dome rooflights in Crewe: what is involved?
Thinking about dome rooflights in Crewe? 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Jobs in Crewe are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Crewe
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Low cost per unit
- Smoke-vent versions available
Before you order: points to check
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Crewe
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 Crewe: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you work alongside my builder in Crewe?
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 Crewe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
