Are they just blowing you smoke? Or are ridge vents as important as they say? More importantly, what is a ridge vent and how does it work? A ridge vent is a non-mechanical vent that runs the entire length of the peak of your home. Compared to other roof vents, they blend well with the profile of the roof and are hardly noticeable. Like other roof vents, ridge vents function to allow rising hot air to release from the attic.
Cool air enters the attic from the soffit vents, constantly moving fresh air under the roof deck as the hot, stale air is allowed to escape from the top. Releasing this hot air extends the life of your shingles, prevents ice damming, lowers cooling costs, and regulates temperature extremes like a cold main floor and a hot upper floor.
Other types of roof vents include box vents, turtle vents, and gable vents. Box vents are essentially a square hole cut in your roof. With the help of soffit vents, they allow hot air to escape the attic.
Turtle vents are non-mechanical curved vents yep, like a turtle shell that allow hot air to escape the attic space. If not used with soffit vents, they typically only release air where they are installed.
Gable vents are rectangles vents generally found on the front or sides of a house, below the roof ridge. If your home already has box, turtle, or gable vents at the time of your roof replacement, you may be wondering if you need to install a ridge vent. So low bidder gets the job. So, the builder specs a ridgevent, cheaper the better. Hot air will not reverse direction and flow downhill to escape a hot attic…out of any vent.
All the prejudicial bashing aside, I guess you are saying that a ridge vent does not work? Apparently, you contend that water can indeed go uphill. I agree that water can rise 1" per 10 MPH wind on a 6 pitch. I know that water enters many ridge vents that I have inspected, as the cause of leaks. I also agree that air has a hard time going back down the ridge vent. I resist ridge vents for those reasons, and the ranting aside, I see no reason given on this thread yet to use them.
Aesthetics, really…? Paint the turbines? All I know is I have 3. All of my builders have us put in turtle vents unless a vault. A builder friend of mine had a house built a few years ago.
The effect of ridge vents for the roof depends upon the energy-efficient nature of the structure. You must have air movement toward the vents to make it an effective solution.
If the rest of the home does not receive circulation, then this option will not work as intended. Some older homes still need to have the older-style vents installed to give it the ventilation levels that are necessary. You must prevent outside air from crossing over this product for it to work effectively. There is a chance that they could leak water during heavy rains.
Some homes are in the path of storms where the wind strikes the roof in such a way that rain blows in right through the vents. If you find yourself in this situation, then you must inspect your attic for water damage frequently. The only way to prevent the issue is to take the vents out, replacing them with a product which offers a more water-tight experience for your roof.
If you have insulation in your attic, then the dampness caused in this situation creates even more challenges to face as a homeowner. The initial cost of roof ridge vents is usually higher. Roof ridge vents provide a costly system of ventilation that may not be suitable for the checkbooks of some homeowners. This option might be the updated system which most newer homes use, but if you have an older home, then you might need the soffit vents too.
The soffit vents act like the air intake for the home. That means roof ridge vents are like the exhaust system. They allow the house to breathe correctly. Roof ridge vents and other forms of roofing ventilation work better when homes are in colder climates.
The ridge vent works and is installed in exactly the same way no matter what the climate is like. The only thing that changes is the primary purpose of the vent. The hot summer sun beating down on your roof can super heat the attic air.
Many times mechanical equipment is located in this super heated attic. Cooling a house in summer is expensive and having a super heated attic makes it even worse. Moisture also tends to build up more in hot months. Both from the hot humid air and mechanical equipment sweating. Expelling this humidity is one of the most important jobs performed by the ridge vent. In mixed climate areas, attic ventilation with a ridge vent serves both roles, depending on the season. Provided of course that you have soffit vents or some other form of intake to bring in fresh air.
