13 best roof vents

Roof vents are essential components of ventilation and HVAC systems, particularly in buildings and vehicles like RVs (Recreational Vehicles).Here's what you should know about roof vents:

  1. Purpose of Roof Vents: Roof vents are designed to facilitate the exchange of air between the inside and outside of a structure or vehicle. They play a crucial role in maintaining air quality and temperature control.

  2. Types of Roof Vents:

    • Static Roof Vents: These are non-mechanical vents with no moving parts. They rely on natural convection to allow hot air to escape from the building or vehicle. They are simple and cost-effective.
    • Powered Roof Vents: These roof vents have fans or motors that actively draw air in or expel it from the space. They are more efficient in regulating airflow and can be controlled electronically.
  3. Applications:

    • Residential Buildings: Roof vents are commonly used in residential homes to improve attic ventilation. Proper attic ventilation can help regulate temperatures, reduce moisture buildup, and extend the lifespan of the roofing materials.
    • Commercial Buildings: Larger commercial and industrial structures may also use roof vents to maintain indoor air quality and temperature.
    • RVs and Automotive: In RVs and other vehicles, roof vents are used to provide ventilation and exhaust fumes, cooking odors, and moisture.
  4. Materials and Design: Roof vents are typically made of durable materials such as aluminum, plastic, or galvanized steel. They are designed to withstand weather elements like rain and snow while allowing for airflow.

  5. Installation: Proper installation is crucial for the effectiveness of roof vents. They need to be strategically placed to create optimal airflow patterns. For RVs, roof vents are often equipped with covers or hoods to protect against rain when they are open.

  6. Maintenance: Regular maintenance is essential to ensure that roof vents function correctly. This includes cleaning, checking for debris, and inspecting the seals or gaskets to prevent leaks.

  7. Benefits: Roof vents offer several benefits, including improved indoor air quality, reduced energy consumption by helping with temperature control, and preventing moisture-related issues like mold and mildew.

  8. Accessories: Roof vents may come with additional accessories like remote controls, rain sensors, and thermostats to automate and optimize their operation.

Overall, roof vents are essential components for maintaining proper ventilation and temperature control in a variety of settings, from residential homes to vehicles like RVs, contributing to comfort and indoor air quality.

User questions & answers

Question: Can this be mounted on a flat roof? What is distance to the bottom of vent opening? I would like to use with foam roof
Answer: No. It will only work on a pitched roof. They do make one for a flat roof. Ask at any building supply place.
Question: Is it galvanized steel (painted black) as stated in the description, or is it steel that is painted black
Answer: If it's galvanized as the manufacturer states, it's a poor grade. I am skeptical about the "powder coat" claim too. Mine has serious, shingle-staining surface rust in less than 3 years of exposure. True powder coat should last longer than that, and even if it flakes off the supposed "galvanized" metal shouldn't rust. I'd steer clear of this item, it won't last the life of the roof.
Question: I understand that the damper slams up and down in the wind but other 4" galvanized vents have solved that problem.Anybody know which ones
Answer: I have 2 of these installed on my roof for the bathroom exhaust fans. Neither of the units I have have ever had the damper slam up and down in the wind. If this happens it's because they are installed at an improper angle or not secured correctly.
Question: How high does this stick up above the roof plane? It looks much taller than the Broan 634m
Answer: Hi Chris,The roof fiting measures 6.5 inches in the middle,the highest point and about 4.5 at the exhaust opening. Hope this helpsRobert

Question: What is the warranty on the vent

Question: hi its feet to 14” roof hole

User questions & answers

Question: Can this be installed on a vertical surface such as a wall
Answer: Not likely, the bearing only works if it's perfectly level. There's some articulation in the mount to keep it level, but definitely not 90 deg.
Question: dose this have to be on a flat surface? can I install it on a pitched roof
Answer: The vent comes with instructions showing how to set the correct pitch for your roof style. This is not only for a flat roof installation.
Question: I live in a cool coastal climate and need to reduce moisture/molding. Will this help
Answer: Yes
Question: Can rodents (specifically roof rats) gain entry through the vent
Answer: That would be difficult as these things r constantly spinning. What I did was put a fine wire mesh in the attic under the hole that was cut to prevent wasps from entering. Stapled it and have had no issues.

  • Duct conforms to UL181 Class 1 air connector requirements

User questions & answers

Question: Can I purchase only the metal duct connector
Answer: Sorry, I misread your question a few minutes ago. It is the connector, not the tubing you are asking about. I still do not know of any single-item availability from the kit, although you might have luck contacting Broan and asking. If you mean the clamp, search for a 4 inch clamp from hose clamp sellers. They should be readily available in the HVAC world, and used with clothes dryers. If you mean the actual 4 inch diameter sheet metal extension under the hood that the hose connects to, your best bet is probably to take it to a sheet metal shop and have them install one. You may, also, rig one up by attaching a piece of 4 inch cylinder using L-brackets and screws to hold the cylinder in place. Be sure to seal the interface with a long-lasting sealant, such as silicone caulking.
Question: Has anyone had issues with snow piling up too high and blocking the vent? it seems to have a low profile. i live in new england with low pitched roof
Answer: If you use it regularly the warm house air will melt any snow. The flap is protected by the top so even if covered the warm air would escape and melt the snow.
Question: Has anyone experienced problems with this vent leaking in heavy rain? Big box retailer reviews report that
Answer: We bought 2 of these exact kits from a big box retailer and after 2 years both have rusted near the base and one of them started leaking in a recent heavy rain storm. Looking to replace both of mine with galvanized vents.
Question: Is this cap made of aluminum or galvanized steel
Answer: It is not aluminum. I put a magnet on it and It did stick so it could be steel. It is painted so I don't know if it is galvanized.

User questions & answers

Question: pulled flapper, replaced cheesy strip at front of flap and added to other three sides with 3/16 thick, 3/8 wide foam weather strip. is this ok
Answer: No
Question: What is the function of a roof vent cap? Does it keep rain water out of house, or just keep animals out
Answer: I used one for my dryer venting through the roof and one for my bathroom fan vent. It is designed to keep the rain out and of course animals. This particular one is the "vent cap only", you really need to buy the same cap with the vent pipe or you will wind up having to buy the vent cap separately.
Question: Can the damper get frozen shut in the winter
Answer: It's possible, but not too likely. And even if it does, when the bath fan is turned on there will probably be enough air leakage that it would thaw the flap in a minute or two.
Question: I have a 12 in wide metal roof and I need to put a vent to vent out heat from the roof . Would the brown 636 work to do this
Answer: It could probably be made to work, but that's not what this vent cap was intended for. It has a flap in it that is normally closed, that would have to be removed. (This vent cap is normally used for a bathroom vent fan that will push the flap open when the fan is running.) Depending upon the style of metal roof you have, it may be difficult to get this vent cap sealed properly. This one is designed to have its upper flashing edge under shingles. If your "12 in wide metal" is in horizontal rows, that may work. Also, this vent cap is significantly smaller than what it normally used for roof vents. It will probably take three times as many of these as regular roof vents, to vent a given area of roof. In short, yes it probably could be used for a roof vent, but it would not be ideal.

User questions & answers

Question: I have rain going down the pipe now hopefully this locks in ? without special screws ? one i previously bought had no fastening screws can’t use it
Answer: No screws needed, you just shove it down into the stove pipe and it has a rubber seal to keep it secure and in place.
Question: how does the vent insert and hold in place
Answer: All dependent on what you are attaching it to. I used this to provide cover for a vent pipe on my roof and attached it to the vent pipe with sheet metal screws.
Question: Would the 8" fit in ours that measures 8.3"? Wasn't sure if this cap would be too small

Answer: The 19" x 18" is to the outside lips used for mounting under the shingles. The top part of the light is 12" X 12". The hole in my shed that the light goes over is 9" x 9". I just replaced one of these due to a hail storm. Note the top part is removable, if you are replacing an existing one you may be able to just replace the top part.
