POOWEE 4″ Heavy-Duty Steel Roof Vent Cap

Improve attic ventilation with the POOWEE 4″ Heavy-Duty Steel Roof Vent Cap, designed to maximize airflow efficiency while protecting your home from moisture and pests. With a 75%+ efficiency rating—far exceeding standard vents—this roof vent ensures optimal air circulation, reducing heat and humidity buildup that can degrade roofing materials over time. The durable steel construction and black powder-coated finish resist rust and corrosion, making it ideal for harsh climates, while the curved top design prevents water intrusion during rain.

The vent features a quiet, back-draft damper that automatically closes when not in use, blocking outside air and debris while allowing smooth airflow when needed. A removable top simplifies cleaning, and the extended flange ensures a secure, leak-free installation on attics, bathrooms, or range hoods. For dryer use, the included screen can be removed or replaced with a wider mesh to prevent lint buildup. The package includes one 4″ vent and four screws for easy setup.
