How we approach skylight replacement in Tyldesley
We handle skylight replacement across Greater Manchester, including Tyldesley. In short: replacing tired domes and failed glass with a modern rooflight. 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. Skylight replacement suits yellowed domes, misted glass and leaking roof windows.
Tyldesley sits about 2 km from Atherton and 4 km from Leigh, and we cover the whole M29 postcode district and the roads in between.
Options we can specify in Tyldesley
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Misted glass unit replacement only
- Like-for-like size replacement
- Upstand rebuild and insulation
- Option to add opening and rain sensor
- Better thermal performance
Things we check at survey
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Planning, building control and Tyldesley
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. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight replacement in Tyldesley
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.
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Do I need to be at home for the survey in Tyldesley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Tyldesley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
