Rules that apply in Wales
In Wales, a new rooflight opening generally needs building regulations approval, and a replacement needs either a scheme-registered installer's certificate or a building notice to the council. We are not registered with a scheme, so we use a building notice and show the fee on the quote. Rooflights must meet 2.2 W/m²K and roof windows 1.4 W/m²K. Planning is tighter than in England: rooflights are not permitted development in conservation areas, National Parks, Areas of Outstanding Natural Beauty or World Heritage Sites, so we check your address before quoting.
Common questions in Mid Glamorgan
Is new glass or a new rooflight better value?
If the frame, gaskets and drainage are sound, new glass is usually the cheaper fix. If the frame is cracked, distorted or leaking at the kerb, a full replacement is better value. After the measuring visit we price both so you can compare.
Is the measuring visit charged?
Yes. The first visit measures the existing glass and checks the frame, and it is charged. We confirm that price before you book. The fitting of the new glass is then priced in writing, so you see the full cost before anything is ordered.
How long does new rooflight glass take?
The new sealed unit is made to the measured size, so there is a gap between the measuring visit and the fitting visit while it is produced. We give you the expected timing when we price the glass, and book the fitting once it has arrived.
