What do conservation rooflights in Ashton-in-Makerfield involve?
Thinking about conservation rooflights in Ashton-in-Makerfield? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of conservation rooflights for slate and plain-tile roofs where a quiet roofline matters.

Planning and building rules for Ashton-in-Makerfield
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.
See our building regulations guide for U-values, glazing limits and self-certification.

On a listed building you need listed building consent. In a conservation area, check with the council — many areas have Article 4 directions affecting roof alterations.

We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
