Product Information
Full details
The Chimsoc High Temperature Pipe Flashing is the ideal sealing solution for contractors and DIY enthusiasts installing wood-burning stoves, chimneys, or exhaust vents through various roof types. Its primary benefit is providing a durable, weather-resistant barrier that maintains integrity under extreme heat, though users should ensure their roof pitch does not exceed the 40-degree maximum limit for a proper fit. Featuring a flexible silicone construction, this flashing accommodates pipe diameters ranging from 0mm to 150mm, ensuring a custom-fit seal on roofs with pitches up to 40 degrees.

FAQs
What is the maximum pipe size this flashing supports?
This model is designed to support pipe diameters from 0mm up to 150mm (6 inches).
Can this be used on a flat roof?
Yes, this flashing is fully compatible with flat roofs (0 degrees pitch).
What temperatures can the silicone withstand?
It is rated for continuous temperatures up to 225°C and can withstand intermittent temperatures up to 260°C.
Is the flashing UV resistant?
Yes, the high-quality silicone is engineered for excellent resistance to UV rays and ozone.
What are the base dimensions?
The square base measures 249mm x 249mm.
Do I need to buy sealant separately?
Yes, a high-quality, exterior-grade silicone sealant is required to secure the base to the roof and ensure a watertight seal.
Troubleshooting
Water leakage around the base
Check the sealant bead around the perimeter for gaps; re-apply a high-quality, exterior-grade silicone sealant if necessary.
Silicone appears stiff or brittle
Ensure the pipe temperature is not exceeding the 260°C maximum limit; if exceeded, the flashing must be replaced as the material integrity is compromised.
Flashing is not laying flat on the roof
Verify that the roof pitch is 40 degrees or less. If the pitch is too steep, the base will not conform properly, and you may need to install a custom mounting flange.
Pros and Cons
Pros
- Wide pipe diameter compatibility (0-150mm)
- Superior heat resistance for chimney applications
- Excellent durability against UV and harsh weather
- Easy to trim and conform to irregular roof surfaces
Cons
- Limited to a maximum roof pitch of 40 degrees
- Requires proper sealant/fastener application for water-tightness
- Not suitable for extremely high-heat industrial furnace exhausts
Setup, Compatibility & Care
Installation should be performed on a clean, dry roof surface. Ensure the base is centered around the pipe and check that the pitch does not exceed 40 degrees. Always use a compatible neutral-cure silicone sealant between the flashing base and the roofing material to ensure a moisture-proof bond. Secure the flashing using corrosion-resistant screws spaced evenly around the perimeter of the base. For care, perform an annual inspection to ensure no degradation of the silicone or the sealant bead, and verify that the base fasteners remain tight. Clean the area around the flashing with water and a soft brush if debris accumulates.
