4-Inch Flat Roof Flashing for Selkirk Model HT

This 4-inch flat-roof flashing is designed for compatible Selkirk Model HT / Ultra-Temp chimney installations on flat and very low-slope roofs. Selkirk identifies this component as HT4TCF.

Manufacturer literature describes the flashing as a weather-shedding component for flat and low-pitch roofs up to approximately 2/12 pitch. It helps divert rain and snow away from the chimney penetration when installed as part of the complete roof assembly.

For some profiled metal roofs, a compatible flexible roof boot may be another option when permitted by the chimney and roofing requirements. Compare our #7 High-Temperature Dektite Roof Boot.

Installation Notes

The 4-inch storm collar is sold separately and is used above the flashing as part of the weather-sealing assembly. Follow Selkirk's current instructions and the roofing manufacturer's requirements for placement, fastening, sealing, chimney support, and roof clearances.

Do not assume this flashing is appropriate for every flat-roof material or mobile application. Roof membrane type, chimney temperature, structure, local code, and manufacturer requirements all affect the correct flashing method.
