Confirm the pipe diameter matches the 7 in. cone opening before installation. Set the base into the shingle courses with the upper flange lapped above so water sheds around the penetration, then complete the assembly with the matching T-top cap. Follow the manufacturer’s instructions and local code for penetrations of this size.

Use proper fall protection and OSHA-compliant practices when working on a roof.
