What do conservation rooflights involve?
Our conservation rooflights service in Dyfed covers slim, low-profile steel-look rooflights for period and listed roofs. We survey every job before fixing the price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere.

Planning and building rules in Wales
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Do they suit slate roofs?
Yes — flashings are made for slates and for plain tiles.
Will the council accept it?
We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
Will I need planning permission in Dyfed?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
