Velux Window & Roof Light Installation in North Wales
Bringing Light and Fresh Air Into Your Loft or Extension
At A. Gallagher & Son, we professionally install roof lights and Velux-style windows across North Wales — including Bangor, Anglesey, Conwy and surrounding areas. Whether you’re converting a loft, adding an extension, or simply looking to brighten a dark space, we’ll help you choose and fit the right roof glazing for your needs.
Expert Installation — Branded or Bespoke
Velux is one of the most well-known names in roof windows, and we’re experienced in fitting the full Velux product range. But we’re not limited to one brand — we also install other high-quality roof light systems tailored to your space, your roof structure, and your budget.
Our services include:
-
- Velux window supply and installation
-
- Flat or pitched roof light fitting
-
- Manual or electric opening options
-
- Flashing kits and watertight integration
-
- Internal trimming and finishing
-
- Repairs or replacements for existing roof windows
Whether it’s a single top-hung window or a larger fixed-pane roof light, we’ll make sure it’s installed correctly, safely, and in keeping with your property.
Trained Roofers — No Subcontracted Fitters
Unlike some firms, our installations are carried out by skilled roofers — not general trades or window contractors. That means your roof stays watertight, properly ventilated, and structurally sound. We take the time to ensure flashing and sealing are done to the highest standard, reducing the risk of leaks or future repairs.
If your new roof window is part of a wider renovation, we can work alongside builders or interior trades to ensure a smooth project.
Covering All of North Wales
Based in Bangor, we provide Velux and roof light installation throughout Gwynedd, Conwy, Anglesey and surrounding areas. We work on homes, holiday lets, extensions, converted lofts and more — always with a focus on clear communication, quality materials, and tidy workmanship.
Let the Light In — Safely and Stylishly
