New roof windows transform a dark loft into usable space. We supply and install VELUX roof windows, fixed skylights and sun tunnels across Guildford — with the correct flashing kit for your tile type and fully weathertight installation as standard.
We cover all Guildford postcodes (GU1) and the surrounding area. Free written quotes, no call-out fee, 10-year workmanship guarantee.
Standard and large VELUX centre-pivot windows fitted with the correct flashing kit for your tile profile. The wrong flashing kit is the most common cause of VELUX leaks.
Fixed roof lights for rooms where ventilation isn't needed. Lower cost, suitable for lower pitches and bathroom/hallway applications.
Rigid and flexible sun tunnels bring daylight to rooms with no direct roof access. Typically installed in a half-day.
Failed flashings, broken handles, misted glazing units and seal failures on existing VELUX windows repaired or replaced.
Guildford's stock of Victorian and Edwardian housing has seen significant loft conversion activity. Roof windows are often the difference between a storage loft and a habitable room — and correct flashing for Surrey weather conditions is essential.
Guildford straddles the River Wey in the North Downs gap. Properties on the chalk ridge above the town face significantly more wind exposure and freeze-thaw damage than valley-floor properties.
Conservation area constraints on tile materials in the town centre. Freeze-thaw damage to ridge mortar on elevated North Downs properties. Lead flashing failures on Victorian townhouses.
We cover Guildford (GU1) and surrounding areas including Merrow, Burpham, Farnham. Same-day response available Monday to Saturday. Emergency call-outs 24/7.

Guildford's housing spans an unusually wide range of ages and types — from Victorian townhouses in the conservation area around Quarry Street and the High Street, through 1930s semis in Merrow and Burpham, to modern estates on the town fringe. Each era has specific roofing requirements, and properties in the conservation area have additional planning constraints on materials.
VELUX installation in Guildford requires attention to two details that determine long-term performance: the correct flashing kit for your specific tile profile, and adequate counter-batten height to allow proper weathering above the frame. Both are installation specifics that separate a window that performs for 25 years from one that leaks in year three. We get both right.
Guildford's higher average property values mean the financial case for correct, quality maintenance is particularly strong. A roof maintained correctly over 20 years costs a fraction of a reactive replacement, and documented maintenance history supports premium valuations at sale.
Properties on the chalk ridge above Guildford — in Merrow, on the North Downs approach — face significantly more wind exposure than the valley floor. Ridge tile displacement after winter storms is more common on elevated Guildford properties than on comparable properties in more sheltered positions.
"Three VELUX windows fitted as part of our loft conversion. Correctly flashed, not a drop in 18 months. Would recommend without hesitation."
"Had a sun tunnel put into the dark hallway. Incredible difference — transformed the space. Half a day's work."
"Existing VELUX had been leaking since the previous owner. Wrong flashing kit — sorted on the first visit. Should have been done right first time."
A standard VELUX centre-pivot window supplied and fitted with the correct flashing kit for your tile type typically costs £600–£900 in Guildford. Sun tunnels start from £350. We provide a free written quote once the specification is confirmed.
Most roof window installations are permitted development. Exceptions include conservation area properties and listed buildings. We'll advise on whether consent is needed and help specify an installation that stays within PD rights where possible.
The most common cause is an incorrect flashing kit for the tile profile — widespread when windows are fitted by roofers unfamiliar with the VELUX system. Other causes include failed butyl tape seals and displaced sill sections. Most leaks can be fixed without replacing the window.
VELUX centre-pivot windows require a minimum 15° pitch. Below this, a flat roof window or sun tunnel is the right solution. We'll confirm suitability at survey stage.
