What do dome rooflights involve?
Across Greater Manchester, our dome rooflights work covers polycarbonate and acrylic domes for flat roofs, new or replacement. Survey first, fixed price second, fitting third.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. 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.

Planning and building rules in England
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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 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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do you fit dome rooflights across Greater Manchester?
Yes. We survey and fit dome rooflights across Greater Manchester, including Manchester, Oldham, Wigan.
