Preventing ice dams and frozen vents


Learn about common roof issues caused by cold temperatures and snow loads. The course instructor, an energy auditor, will focus on the causes of ice dams on the roof, frozen sewer vents, and how to remediate problems when they occur. He will also discuss air leaks, heavy snow loads, and mold in the ceiling. Students will learn how to prevent these issues in new construction and how to retrofit an existing structure so they don't occur again.
