What do flat rooflights in Ellesmere Port involve?
We handle flat rooflights across Cheshire, including Ellesmere Port. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Ellesmere Port, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
Neighbouring towns include Chester (10 km) and Halewood (10 km). We offer a survey date when we reply to your enquiry.

Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Consents for flat rooflights in Ellesmere Port
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Common questions
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Can you work alongside my builder in Ellesmere Port?
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 Ellesmere Port?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
