Skylights and roof windows transform dark, underused spaces into bright, inviting rooms filled with natural light. Apex UK Roofing installs, replaces, and repairs skylights throughout Guildford and the wider Surrey area, working with leading brands like Velux, Fakro, and Keylite to illuminate your home from above.
Skylight and roof window installation involves cutting an opening in the roof structure, fitting a structural timber frame or trimmer, installing the window unit with its integrated flashing kit, and ensuring a completely watertight seal with the surrounding roof covering. We install the full range of roof window types: centre-pivot windows for easy cleaning and operation, top-hung windows for unobstructed views, fixed flat glass units for flat roofs, conservation-style windows for period properties, and large format or combination windows for maximum light. All installations in Guildford are carried out to manufacturer specifications using genuine flashing kits, ensuring warranty validity and long-term weatherproofing.
We handle Building Regulations compliance, including structural calculations for trimmer openings, thermal performance requirements, and means of escape provisions where applicable. For properties in Guildford, where the historic county town of Surrey with a wealth of period properties, steep hillside housing, and modern developments requiring diverse roofing expertise, we can advise on the best window positions to maximise light while respecting the character of your property and any planning constraints that may apply. Options include electrically operated windows, solar-powered blinds, and rain sensors for hands-free ventilation.
We visit your Guildford property to discuss the best position, size, and type of skylight for your needs, taking into account the roof structure, orientation, and any planning considerations.
We cut the opening, install structural trimmers to support the surrounding roof, and prepare the area for the window fitting, all in compliance with Building Regulations.
We fit the skylight or roof window with its genuine manufacturer flashing kit, ensuring a perfect weathertight seal with the surrounding tiles or slates.
We complete the internal trim, insulate around the window frame, and install any blinds or accessories you have chosen. The opening is left ready for your decorator.
We are authorised installers for Velux, Fakro, and Keylite, ensuring your skylight is fitted to manufacturer standards with full warranty protection.
Every skylight installation meets current Building Regulations for structure, thermal performance, and fire safety.
Using genuine manufacturer flashing kits, we guarantee a completely watertight installation that integrates seamlessly with your existing roof.
From compact bathroom skylights to large format combination windows, we supply and install the full range to suit every application and budget.
In most cases, skylights fall under permitted development and do not require planning permission, provided the window does not protrude more than 150mm above the existing roof plane and is not on a front-facing roof slope in a conservation area or other designated area. Listed buildings always require listed building consent for skylight installation. If your Guildford property is in a conservation area or is listed, we can advise on the correct approach and assist with any applications needed.
We install roof windows from all leading manufacturers including Velux, Fakro, and Keylite. Velux is the market leader and offers the widest range of sizes, styles, and accessories. Fakro offers excellent value with a comprehensive range. Keylite features innovative easy-clean and thermal performance technology. We can recommend the best option for your specific requirements and budget during our free consultation at your Guildford property.
The cost of skylight installation in Guildford depends on the window size, type, and specification, the roof covering material, and the internal finishing requirements. A single standard Velux window supplied and fitted typically costs between 800 and 1,500 pounds including the flashing kit. Larger or multiple window installations cost proportionally more. We provide detailed quotations that include the window unit, flashing kit, structural work, and basic internal trimming.
Yes, we install flat roof skylights using specialised flat glass and dome units designed specifically for flat and low-pitch roof applications. These are available in fixed and opening versions, with options for manual, electric, or solar-powered operation. Flat roof skylights are an excellent way to bring natural light into single-storey extensions, kitchen areas, and other rooms beneath flat-roofed sections of your Guildford property.
