Yes. A flashing kit is a mandatory component when fitting a roof window. It creates a watertight seal between the window frame and the roof covering, ensuring rainwater drains away safely without leaking into the building.
Keylite Flashing Kits for Pitched Roof Windows
Keylite roof flashings provide the necessary weatherproof seal required when fitting Keylite Roof Windows into a pitched roof. The flashing sits around the window frame, directing rainwater away from the opening and preventing leaks. The range includes specific profiles to suit different roof coverings, ensuring compatibility with standard interlocking tiles, deep profile tiles, and traditional slate. Standard tile flashings accommodate material profiles up to 45mm, while deep tile options handle profiles up to 90mm, and slate flashings are suitable for materials up to 10mm thick.
These flashing kits are designed to integrate securely with the roof covering across pitches ranging from 15° to 90°. Featuring a unique one-piece bottom apron, they create a neat, reliable finish that reduces the risk of water ingress. The cover flashings require 50% fewer screws during fitting, simplifying the installation process. When securing the window and flashing, standard Roofing Batten is used to support the structure and maintain the correct spacing, ensuring the window sits perfectly flush within the roofline.
Each kit is manufactured from durable aluminium, offering long-lasting protection against weather exposure. The standard recessed fit means the window sits lower in the roof, improving thermal efficiency by reducing cold bridging around the frame. Creating this airtight and watertight barrier is critical to maintaining the performance of the Loft Insulation, preventing moisture from entering the roof space and reducing heat loss. The kits provide a compliant, straightforward method to finish roof window installations efficiently.
Keylite Flashing Kits FAQ's
The correct kit depends on the thickness of the tiles. For standard interlocking tiles up to 45mm thick, a standard tile flashing is required. If the tiles have a deeper profile up to 90mm, a deep tile flashing kit is necessary to ensure proper coverage and a secure fit.
No, these specific flashing kits are designed exclusively for pitched roofs with an angle between 15° and 90°. Flat roof installations require dedicated flat roof window systems with their own specific kerbs and sealing methods.
Installation typically requires standard hand tools. You will need a hammer, a screwdriver for securing the fixings, a tape measure, and a utility knife to trim the roofing felt. The flashing kits feature a one-piece bottom apron and require fewer screws, keeping the necessary tool list short.
Maintenance involves visually inspecting the flashing once or twice a year. Clear away any leaves, moss, or dirt that accumulates around the window edges to ensure water can flow freely down the apron and away from the window frame.
