New roof windows transform a dark loft into usable living space. We supply and install VELUX roof windows, fixed skylights and sun tunnels across Farnham — from a single loft conversion window to a full run of roof lights on a rear slope.
We supply and install the full VELUX range alongside other leading brands. All installations include correct flashing kits, tile-in sills and full weatherproofing to meet Building Regulations requirements.
The standard VELUX centre-pivot roof window in standard and larger sizes. Top-hung option also available for higher ceilings. We fit the correct flashing kit for your tile type.
From £600 supplied & fittedFixed roof lights for living spaces, bathrooms and hallways. Lower cost than opening windows where ventilation isn't required. Suitable for lower roof pitches.
From £450 supplied & fittedRigid or flexible sun tunnels bring natural light to rooms with no direct roof access — ground floor hallways, bathrooms and kitchens below pitched roofs. Installed in a half-day.
From £350 supplied & fittedFailed VELUX flashings, cracked seals, broken handles and misted glazing units repaired or replaced. We hold common VELUX spares for faster turnaround.
From £150VELUX centre-pivot windows require a minimum 15° pitch. Below this, a fixed flat roof light or sun tunnel is the appropriate solution. We'll advise at survey stage.
Roof windows are permitted development on most properties. Conservation areas and some listed buildings require consent — we're familiar with Farnham's planning requirements.
The correct flashing kit depends on your specific tile profile and batten gauge. Incorrect kits are the most common cause of VELUX leaks — we specify and fit the right kit every time.
Roof windows in habitable rooms require glazing to meet current thermal and safety standards. We install to current Building Regulations as standard — no extra charge.

Farnham's stock of 1930s and post-war semis has seen significant loft conversion activity over the last decade. Roof windows are frequently the difference between a storage loft and a habitable room — and done properly they add considerably more value than they cost.
We work alongside loft conversion builders and architects across Farnham, Fleet and Aldershot, or directly with homeowners on standalone roof window installations. Either way the outcome is the same: correctly specified windows, properly flashed, fully weathertight.
Properties in Farnham's conservation area around the town centre may require permitted development rights to be confirmed before installation. We'll advise on the position and specification to keep the installation within PD rights where possible.
"Three VELUX windows fitted as part of our loft conversion. Properly flashed, not a drop of water in 18 months. The builder who did the loft couldn't get the flashing right — these guys sorted it first time."
"Had a sun tunnel put into our dark hallway. Incredible difference — completely transformed the space. Half a day's work. Would do it again without hesitation."
A standard VELUX centre-pivot roof window supplied and fitted with the correct flashing kit for your tile type typically costs £600–£900 in the Farnham area. Sun tunnels start from £350 supplied and fitted. We provide a free written quote once we've confirmed the specification.
Most roof window installations are permitted development and don't require planning permission. Exceptions include properties in conservation areas, listed buildings, and where the window faces a highway. We'll advise on whether consent is needed during the survey and can help identify the appropriate installation position to remain within PD rights.
The most common cause is an incorrect flashing kit for the tile profile — a widespread problem when windows are fitted by roofers unfamiliar with the VELUX system. Other causes include failed butyl tape seals around the flashing surround and damaged or displaced sill sections. Most leaks can be fixed without replacing the window.
VELUX centre-pivot windows require a minimum 15° pitch and work up to 90°. Below 15° you need a flat roof window or sun tunnel. For very shallow pitches (under 20°) we fit an additional underpitch flashing kit to ensure weathertightness. We'll confirm suitability at survey stage.
