What do conservation rooflights in Prescot involve?
For Prescot homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Prescot, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
Prescot is around 12 km from Liverpool, and we survey and fit throughout that part of Merseyside, including the L34 district.
Options we can specify in Prescot
- Steel or aluminium frames
- Flashings for slate or plain tile
- Manual or electric opening
- Toughened or laminated double glazing
- Blinds
- Double glazed behind a period look
- Suits slate and plain-tile roofs
What to check first
- Lead or matching flashings may be required
- Projection above the roof line is limited — usually as flush as possible
Planning and building rules for Prescot
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.
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. 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.

Conservation rooflights in Prescot: questions
Can you copy an original rooflight?

We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Prescot free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
