Pitched roof windows in Farnworth: what is involved?
We handle pitched roof windows across Greater Manchester, including Farnworth. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
Jobs in Farnworth 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.
Specification options
- Centre-pivot or top-hung
- Flashings for tiles, slates or recessed fitting
- Double or triple glazing

Before you order: points to check
- Front-facing roof windows can need permission in conservation areas
- Rafters may need trimming for wider windows
Planning, building control and Farnworth
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Pitched roof windows in Farnworth: questions
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Do you fit pitched roof windows in Farnworth?
Yes. We survey and fit pitched roof windows in Farnworth and across Greater Manchester. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Farnworth?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
