Ridge & pitched glass roofs for Caerphilly: the essentials
Our ridge & pitched glass roofs service in Caerphilly covers dual-pitch glazed roofs for side returns, links and long extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Caerphilly, as anywhere, ridge & pitched glass roofs are the usual choice for terraced-house side returns that would otherwise be dark.
Neighbouring towns include Risca (9 km) and Pontypridd (9 km). We offer a survey date when we reply to your enquiry.

Consents for ridge & pitched glass roofs in Caerphilly
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Common questions
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
Will I need planning permission in Caerphilly?
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.
Is the survey in Caerphilly free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
