Buying Guide

Match vent diameter to your ducting

Choose a 6-inch or 8-inch vent to align with existing ductwork to avoid adapters that can reduce airflow and complicate installation

Prefer dampers that seal well

Look for built-in damper designs—common on the Hon&Guan and Broan-NuTone style units—to reduce backdrafts and pest entry when the fan is off

Select durable material for climate

Galvanized steel and stainless steel caps resist corrosion in wet or coastal environments better than untreated metals

Consider removable or serviceable designs

Removable vent caps simplify cleaning and maintenance, which helps maintain airflow and extends product life

Check roof-mounting compatibility

Verify flashing and flange dimensions and that the kit or cap is compatible with your roof pitch and shingle type before purchase
