Keylite Flashing

Keylite flashing kits seal roof windows into tile or slate roofs to keep out wind and rain. They create a snug, weathertight fit between the window and surrounding roof covering. Roofers, builders and DIYers use them when installing rooflights, loft windows and daylighting.

Our range includes flashing kits and trims tailored to common tile and slate profiles. You’ll find sitting options that match roof pitch and cladding type. These products make fitting roof windows quicker and neater while reducing leaks.

Choose the right Keylite flashing to protect roof openings from moisture and drafts. A correct seal improves performance in all weather and extends window life. Pick a kit that matches your roof material for reliable, long-lasting protection.
