Flashing Kits

A boiler flue flashing kit is used when installing a vertical flue kit through a flat or angled roof. They are quick and easy to install and provide a weather tight seal to the roof and help to stop any water leaking into the flue system. We have flashing kits and weather collars suitable for pitched and flat roofs. We recommend that they are fitted by a Gas Safe Registered Installer.
