Roof windows transform dark loft spaces into bright, ventilated rooms. We supply and install the full range of Velux roof windows, sun tunnels and skylights — from straightforward replacements to new installations in existing roofs. Every installation uses the manufacturer-approved flashing kit for your specific roof covering.
The correct roof window depends on roof pitch, tile type, and what you need the window to do. Centre-pivot windows suit standard pitches. Top-hung windows give more headroom. Conservation-style flush-fit windows are required in some Stanmore conservation areas.
The roof window itself rarely leaks — it is the flashing around it that fails. We use only Velux-approved flashing kits matched to your specific tile profile. Generic flashings and site-made solutions are the primary cause of roof window leaks in Stanmore.
If you are converting your loft, Building Regulations require minimum window areas for natural light and ventilation, plus at least one opening window for fire escape. We work with your builder to position and size windows correctly for compliance.

Yes — we cut into the existing roof, install the window with correct structural support, and weatherproof with the appropriate flashing kit. Planning permission is not usually required unless you are in a conservation area.
The three most common causes are: incorrect or deteriorated flashing, condensation mistaken for a leak, and failed window seals. We diagnose the actual cause before quoting — it is often a straightforward flashing repair rather than a window replacement.
Minimal — clean the glass, oil the hinges annually, and check the flashing seals every 2-3 years. Velux windows typically last 20-30 years before the seals and mechanisms need attention.
Yes — old skylights are often single-glazed, poorly sealed and difficult to open. A modern Velux replacement gives you double glazing, proper ventilation, and a reliable weatherproof seal.
Yes — sun tunnels bring natural light to internal rooms that cannot have a conventional window. They are ideal for bathrooms, hallways and stairwells in Stanmore properties.
Window size depends on room floor area — Building Regulations specify minimum glazing areas for habitable rooms. We calculate the correct size based on your room dimensions and roof pitch.
Harrow's hilltop position has shaped its roofing history for centuries. Harrow School, founded in 1572, sits atop one of London's highest points at 124 metres — and the roofs of its listed buildings have withstood four centuries of some of the most aggressive weather exposure in Greater London. The conservation area around the Hill contains Grade II listed buildings where original Welsh slate and handmade clay tile roofs demand specialist maintenance using period-appropriate materials and techniques.
Pinner's conservation area and village character drive property premiums that make roof maintenance an investment priority. Tudor and period properties on Pinner High Street and the surrounding conservation area require specialist roofing skills — lime mortar repointing, handmade peg tile sourcing, and lead detailing that matches the original specification. These are not jobs for general builders.
Every job follows our standard quality process: free inspection and assessment, written quote with full scope of work, professional installation by our own team using specified materials, post-completion inspection with photographic record, and a written guarantee. This process applies to every job regardless of size — a £200 repair gets the same professional approach as a £15,000 re-roof.
We specify materials based on the specific conditions of your property — its age, construction type, exposure and the performance requirements of the job. We never use the cheapest available option as default — we use the right option for your situation and explain why. All materials are sourced from established manufacturers with proven track records.
All work carries our written workmanship guarantee. The guarantee period depends on the scope of work — from 2 years on minor repairs to 10 years on full installations. Guarantees are transferable if you sell the property. Materials carry the manufacturer's own guarantee in addition to our workmanship cover.
No call-out fees. No obligation. Just an honest quote from a local Stanmore roofer who turns up when they say they will.
