The Chimsoc High Temperature Pipe Flashing is designed for professional installers and DIY enthusiasts looking to secure a reliable, weather-resistant seal around chimney or exhaust pipe roof penetrations. Its primary benefit is a high-grade silicone construction that maintains flexibility and integrity in extreme heat, though users must ensure their specific roof profile is compatible with the 445mm x 445mm base size for a proper seal.

It can handle continuous temperatures of 225°C and intermittent temperatures up to 260°C.
It is designed for pipes with outer diameters between 160mm and 300mm.
Yes, the high-quality silicone is engineered to be resistant to UV, ozone, and harsh weather conditions.
Yes, it is highly suitable for metal roofs, as the flexible base can be shaped to fit corrugated profiles.
Yes, while the flashing provides the seal, applying a high-temperature rated roof sealant under the base and at the collar is recommended for a secure installation.
Check the sealant application around the perimeter of the base; you may need to re-apply high-grade roof sealant.
Ensure the silicone cone has been trimmed to the correct diameter mark for your specific pipe size.
Ensure the roof surface is clear of debris and consider using additional fasteners to pull the base tight against the roof profile.
To install, first trim the silicone collar to fit your pipe diameter snugly. Slide the flashing down the pipe until the base sits flush against the roof. Secure the base using appropriate fasteners or rivets suitable for your roofing material. Apply a bead of high-temperature-rated sealant around the edge of the base and the pipe interface to ensure a watertight bond. For care, perform an annual visual inspection to check for debris accumulation or signs of sealant degradation. Clean the surface with water and a soft brush if soot or grime builds up.
