Decktite is used for flashing ducting, pipes and flues on roofs. The product brand name itself is called Dektite and its purpose is to create a waterproof seal. Decktite is also commonly referred to as a pipe boot since it is a rubber cone with an aluminium flange that attaches smoothly to the pipe on a roof.
Decktite (dektite) flashings are commonly seen on metal, slate and tiled roofs and items exposed to high temperatures (chimneys etc). Decktite can withstand temperatures of -50°C to 115°C and up to 150°C intermittently. This is because it is made from EPDM and silicone, which means it is highly resistant to ember attacks (airborne burning fragments).
