Conservation rooflights in Hayes: what is involved?
Conservation rooflights in Hayes means slim, low-profile steel-look rooflights for period and listed roofs. We cover the UB3 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
Hayes is around 21 km from central London, and we survey and fit throughout that part of Greater London, including the UB3 district.

Do you need permission in Hayes?
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. 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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Yes — flashings are made for slates and for plain tiles.
