GROWNEER 4 Inch Roof Vent Galvanized Steel Roof Vent Cap, Removable Roof Exhaust Vent for Houses Bathroom Attic Kitchen(4 in-Bilateral)

Overall good product and fit perfectly.

Giving it 4-stars, because I wish it had a “flapper” (in addition to the grating), to totally prevent not only bugs, but directional rain. The openings are angled, however sideways rain would likely admit water.. Otherwise it’s built very well. I did have to caulk around the grating, as the gap was a bit much

La caja metálica es más fuerte de lo que imaginé.

I ordered this vent to install a vented microwave and it's worked wonderfully. installation is tricky so you may need a pro if you're uncomfortable with the process. it's a rather tool-intensive install (drills, saws, caulking and cutting) so be sure to have everything you need before you start or else you'll have a hole in your roof

Well build. It fits outside of 4 inch schedule 40 pvc pipe like glove. However, the housing of the cap should be slightly larger to maximize airflow. Even if vent area is already sufficiently large, a larger housing would be beneficial for marketing purposes.Also, a wall vent variation of this cap is needed, as I could not find one on the market.

I lost the roof vent for over my microwave off the top of my RV on the freeway, so I needed a new one.I painted this unit white and drilled more screw holes in the flange to create a better seal, since it's going on a flat roof and won't have the benefit of layered roofing and gravity to move water away and it will be moving down the highway.I had to enlarge the hole a little for the inset, but no biggie. I just got a 6" long blade for my jig saw and drew around the outside of this vent's exhaust tube, then followed that line to cut it out. It took less than a minute to do it, which is a tiny fraction of the time I spent on gathering the tools and materials for the install.If course, I had other things I was doing, so I waited until the last minute when it was about to rain before I actually got started. I don't know why I do that. But, it only rained on the microwave a little before I got it buttoned up, so no real calamity, right?I put a bead of Through the Roof sealant where the tube and flange meet and used white butyl tape (the kind with nothing but the goop) under the flange and subbed out the screws for ones with sealing washers and hex heads.I don't know if you would exactly recognize mine as the same thing that arrived, but it got here as a high-quality vent and it stayed that way.I'm very happy I ordered this in time to procrastinate the job and have it to install at the last minute.Thank You to the seller. The microwave in the RV out there thanks you, too, I'm sure.

I wonder who the heck wrote the other reviews? For one, this is more along the lines of 4.5 inches, be prepared to special order a reduced or something more then tape for a 4 in duct. And the damper? There is no damper, just an anti-bug screen..Ignoring those discrepancies, it is a really strong and well made piece.

Review of GROWNEER Roof Vent 6 InchI recently invested in the GROWNEER Roof Vent, and I can confidently say it’s one of the best additions I’ve made to my home’s ventilation system. This 6-inch removable roof vent boasts impressive build quality, and it's clear that the manufacturers paid great attention to durability in their design. The galvanized steel construction gives it a robust feel, and I believe it will stand the test of time against outdoor elements such as rain and snow.One of the standout features is the built-in screen. Unlike typical window screens that tend to be flimsy, this screen is both thick and strong, enhancing the overall quality of the vent. It acts as an effective barrier against debris while still allowing optimal airflow. I appreciate how easy it is to clean; the entire vent disassembles smoothly, allowing for quick maintenance without any hassle.Installation was surprisingly straightforward. Even for someone like me, who is not particularly handy, the process was manageable. The design is user-friendly, ensuring that anyone can set it up without needing professional assistance.Functionally, the vent performs excellently. I’ve noticed a significant improvement in airflow throughout my home, which has positively impacted indoor comfort levels. The built-in damper is another great feature—it helps control airflow effectively while minimizing backdrafts, making this vent both practical and efficient.Overall, I am very satisfied with my purchase of the GROWNEER Roof Vent. It merges durability, ease of installation, and high performance into one well-designed product. If you’re in the market for a reliable roof vent that combines quality with functionality, I highly recommend this one. It’s a worthy investment for anyone looking to improve their home’s ventilation system.
