How we approach skylight replacement in Failsworth
Skylight replacement in Failsworth means replacing tired domes and failed glass with a modern rooflight. We cover the M35 district and the rest of Greater Manchester, with a survey before any price is fixed.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Skylight replacement suits older extensions due a modern rooflight.
We work across Greater Manchester, including Failsworth, and in neighbouring towns such as Droylsden and Ashton-under-Lyne. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Like-for-like size replacement
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs

Things we check at survey
- Enlarging the opening changes the structure and may need approval
- Old glass and domes are disposed of responsibly
Consents for skylight replacement in Failsworth
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Will I need planning permission in Failsworth?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
