The Chimsoc High Temperature Rubber Pipe Flashing is the ideal choice for professional roofers and DIY installers who need a reliable, heat-resistant seal for stove pipes, flues, or exhaust vents passing through a roof. Engineered to handle extreme thermal ranges and harsh weather, this flashing ensures a secure, leak-proof barrier for pipe penetrations; however, users should carefully measure their pipe diameter and roof pitch to ensure compatibility before starting the installation.

It is designed for pipes ranging from 0mm up to 150mm in diameter.
No, this specific model is rated for roof pitches between 0 and 40 degrees.
The silicone construction is specifically engineered for high resistance to UV and ozone, making it suitable for long-term outdoor exposure.
Yes, with a continuous rating of up to 225°C and intermittent spikes to 260°C, it is well-suited for standard wood-burning stove flues.
You will need a sharp utility knife to trim the silicone to size, a drill for fasteners, and high-quality roofing sealant.
Verify that the sealant applied to the base is intact and check that the pipe-to-flashing seal is tight. Re-apply roofing sealant if gaps are found.
Ensure the fasteners are spaced correctly around the perimeter and use a flexible roofing sealant to bridge the gap between the base and the roof surface.
Installation requires selecting the correct diameter trim point on the silicone cone to ensure a snug fit around the pipe. Once the cone is trimmed, slide the flashing over the pipe and secure the base to the roof using mechanical fasteners and a high-quality, heat-rated roofing sealant or adhesive. Ensure the base is pressed firmly into the contours of the roof to prevent gaps. For maintenance, periodically inspect the rubber for signs of cracking or UV degradation, especially after extreme winter or summer seasons, and check that the fasteners remain tight and the sealant has not separated from the roofing surface.
