Looking to replace an old roof vent for my dryer. I noticed this one and was wondering if it can be used with a dryer? I saw that it has a metal mesh screen to keep out animals and didnt know if this would stop up lint and make this not a good choice for pairing with a dryer.

Answer: 
You can NOT use this produce for a dryer unless you remove the screen. It is illegal to install a screen on a dryer vent opening.

My gas furnace vent allows outside wind and cold air to come out of inside heat vent. Do you have anything that will stop this? (example: when the wind is blowing outside after furnace has shut down, cold air from outside comes in through heat vents inside of house. Need a air flow vent that closes when heater is off and open when heater is on.)

CUSTOMER REVIEWS

Rated 4.5 out of 5 by 14 reviewers.
Rated 5.0 out of 5.0 by Goose Neck Vent Solid metal construction. Doesn't seem to have enough sealant around parts that come together and rivets, but not a big deal - just use some extra roofing caulk wherever is needed. The flapper inside works fine but needs a strong air flow to push it open. I have to turn my range hood fan on "high" to do that. Overall, it is a good product. April 26, 2016
Rated 5.0 out of 5.0 by Through the roof....... This one has the tube that goes through the roof so that the hose is easy to attach. September 1, 2015
Rated 4.0 out of 5.0 by Gooseneck vent The gooseneck vent looked very sharp after the installation. The base flashings are a little small they could've been bigger to be able to cover and inter-lap with the roofing shingles on the roof deck We just extended the flashings out . February 26, 2016
Rated 5.0 out of 5.0 by Excellent fix for my problem I bought this for a bathroom exhaust fan which had a flat opening. Every time we had a strong wind and rain from the north, water made its way into the house. This solved the problem while keeping out critters. February 10, 2016
Rated 1.0 out of 5.0 by Very Unhappy I installed this vent during the dry summer here in the Pacific Northwest. This winter, now that it's raining, the inside of it is full of water that's leaking down, inside the vent, between the internally facing vent hose and the vent housing. Again, my roof installation isn't leaking, the vent is full of water. This is on a nicely pitched roof, with proper installation. All I can think is that it's either condensation or rain that's able to get into it. December 24, 2015
Rated 5.0 out of 5.0 by Excellent product Vent was easy to install. I used a "wye" in order to connect both bathroom fans using insulated ductwork. September 1, 2015
Rated 5.0 out of 5.0 by Great Product Great product, Installed easy. Home depot staff was great in directing me to what I needed. September 1, 2015
Rated 5.0 out of 5.0 by Works perfectly! Outstanding product works perfectly keeping out pesky birds!!! June 9, 2015
