Rooflights for Porthmadog homes and buildings
We survey, supply and fit skylights and rooflights in Porthmadog and the LL49 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.
Jobs in Porthmadog are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules in Wales
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. 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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Skylight questions: Porthmadog
How do I book a survey in Porthmadog?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Porthmadog free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Porthmadog?
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.
Do I need to be at home for the survey in Porthmadog?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
What guarantees do I get?
Products carry the manufacturer's own warranty, which we pass to you with the product data. Our workmanship terms are set out in the quote.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
