Roof Windows in Guildford
Roof window installation is the supply and fitting of a pitched-roof window — commonly known by the Velux brand name regardless of manufacturer — into an existing or new roof structure, including trimming the rafters, fitting the flashing kit, and making the surrounding roof covering weathertight.
In Guildford, that covers Onslow Village, Merrow, Burpham, Stoughton, Westborough, Charlotteville, Shalford. Guildford is Surrey's county town, with a historic cobbled High Street, a substantial university population, and residential areas ranging from Victorian terraces near the centre to larger detached houses in the surrounding hills, close to the North Downs and Surrey Hills.

Most roof windows fall under permitted development, provided they don't project significantly beyond the roof plane and meet other standard criteria, but conservation areas and listed buildings can have additional restrictions. We confirm the position for your specific property before ordering.
