What are conservation rooflights?
Our conservation rooflights service in Somerset covers slim, low-profile steel-look rooflights for period and listed roofs. We survey every job before fixing the price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet.

Planning and building rules in England
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

How the job runs

- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Do I need consent for a conservation rooflight?
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.
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
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.
Do they suit slate roofs?
Yes — flashings are made for slates and for plain tiles.
Will I need planning permission in Somerset?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
