Roof Vent Cap - Hon&Guan Roof Vents 4 Inch Galvanized Steel Bathroom 4 Roof Exhaust Vent for Ventilation System-with Damper, Black

My roofer installed this vent Cap when our home was being re-shingled. It is used to vent bathroom fan. The vent works great, no leaks, no issues. Flap closes when not in use to prevent bugs from entering exhaust pipe. Recommend this vent.

Seems well built, installed easily.

Seem like good quality did not install yet

Hasn’t been installed yet but appears to be made well with quality materials. The damper seems to move well and it is unobstructed in its movement. I’m anticipating many years of use from this product.

great quality and price

This event worked where others did not I put it on there to rain doesn't come in easy to put down put it in the same hole of my older vent and it's bigger let's out more heat. You can really see the difference.

Nice product the screens actually block off all the opening so that no bugs can get inside I purchased one from Home Depot and bees could get inside of it that's how big gaps it had in the screen I took the one back to Home Depot and purchase two new ones from Amazon nice product

I bought both the 4-inch and 6-inch models. The quality looks better than those at Home Depot and Lowe's. Unfortunately, the back of the 4-inch version is not sealed—you can see a gap in the first photo. Light passes through the gap, as shown in the second photo. The 6-inch version has the back panel sealed and connected to the base panel (third photo). However, light still pass through the hole at the corners (forth and fifth photos). I sprayed water around the unit. I sadly confirmed water leaks through the vent hole.
