Rooflight upstands & kerbs in Ormskirk: what is involved?
For Ormskirk homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
Neighbouring towns include Maghull (7 km) and Skelmersdale (7 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Ormskirk?
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. 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. 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.

Rooflight upstands & kerbs in Ormskirk: questions
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Do I need to be at home for the survey in Ormskirk?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Ormskirk free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
