The New Standard for Commercial Roof Laps

SecureLap® is a unique roof lap jointing system developed specifically for insulated panel roofing. SecureLap® changes the way long run panel roof runs are designed and installed. SecureLap provides a solution to the troublesome “sheet to sheet endlap” and offers a real alternative to the more expensive “expansion joint” system which requires extra purlins and purlin cleat modifications.

The SecureLap® roof jointing system is designed for pierced fixed panel roofing. It allows for the installation of lapped panels on standard purlin framing and provides a combination of a strong joint and a weather-resisting seal between lapped sheets.

SecureLap® is significantly easier to install than current lapping alternatives. After the lower level panel is secured to the bottom half of the jointing purlin, the SecureLap sealing strip is fitted. The upper level sheet packer is then fitted to the top half of the jointing purlin before the upper level panel is fitted. (See more details in the installation process). Patented, cutting edge technology provides strength and water ingress security while preserving the integrity of the existing roof warranty.
