Hard Wired Powered Attic Vents
Powered attic vents are powered by a motor-powered fan and controlled by a switch or preferably a humidistat. The fans can circulate the air in the attic or similar confined space or move hot out of the area through a roof vent.
Powered attic vents are well suited to applications where you must expel high volumes of air. The powered vents are used extensively in factory or warehouse environments, often in conjunction with ridge vents.
The downside of this system is that the fan-created noise may cause discomfort in some applications and, secondly, being hard-wired to the electrical supply costs money to run.
Various designs of power attic vents are available for commercial and domestic use. Selecting which will suit your particular application may require advice from a professional.
A hard-wired powered attic vent is essentially just an exhaust vent. They require ample inlet vents to prevent a negative pressure buildup in the attic.
Powered attic vents often have a louver-type grid or downward-facing exhaust pipe that expels attic air from the roof and, simultaneously, ensures that the opening in the roof remains weatherproof.
What Is The Best Way To Vent Your Attic
For the best results, place roof ventilation near the roof’s peak and soffit vents in the eaves. Air flows in through the soffit vents and out through the roof vents. Vents come in various styles. We chose rectangular, hooded roofing vents and rectangular soffit vents because they’re easy to install.
Protection Ability Against Harsh Weathers:
Well, weve mentioned external baffles and how they resist the strong gust of wind from entering. However, baffles arent the only thing that resists the harsh weather.
In fact, there are different weather filters that work in protecting the attic from intense weather. So, before buying a ridge vent, make sure it has a dedicated protection system against harsh weather and train/dust/wind/snow.

Ridge Vent: What Is It And How Does It Work
A poorly ventilated home is an unhealthy home. Lack of proper ventilation can cause a range of issues, including mold and mildew, and damage to your homes structure. A ridge vent runs along the highest point, or ridge, of your roof and is designed to help ventilate your home and keep it healthy.
Below we discuss what a ridge vent is, what it does, how it works, and how to install one.
Ways To Hide Your Return Vent Without Blocking Airflow Home Inspection Insiderwhy Is Ventilation Important
Ventilation is crucial in ensuring that your home performs at its best in terms of breathability, air circulation, and safety.
Hot air can rise out of the building if the roof has adequate venting while simultaneously removing moisture.
As a result, the roofs insulation remains dry, the airflow within the home remains efficient, and the temperature of the building remains at a comfortable constant.
In older buildings, ventilation was not as much of a concern because these buildings are not airtight, so that the air could escape at multiple points throughout the building envelope.
Contemporary homes, conversely, have become so well-sealed and insulated that hot air often has nowhere to escape. As a result, the hot air escapes through the roof through properly placed vents to prevent moisture and humidity build-up within the home.
A home without good attic ventilation can cause many undesirable effects to the attic space itself, the roof, the rest of the house, and as a result, may have an effect on your lifestyle within the home.
Poorly ventilated buildings will have a poor quality of indoor air due to the air in the attic not having anywhere to go, resulting in dead, stale air.
Due to the rising of hot air, the upper floors of your home may become warmer than desired. As a result of this, air-conditioning systems may become overburdened and overworked in an attempt to keep the homes temperature at a constant level.

What Is A Ridge Vent
Whether you have a roof made of asphalt shingles, luxury slate, or wood shake, it is crucial that you have ventilation for your roof. Inside your home, heat rises. Thats why your attic or upper crawlspace are always so hot. Roof venting allows that heat to be released.
A ridge vent runs the entire length of the ridge of your roof. One of the primary benefits of these vents is the fact that they are not visible from the ground.
Installation Costs Can Get High
Even though there are many benefits of roof ridge vents, like cost-effectiveness, you still might want to look out for high installation costs in the long run, unlike turbine roof vents.
So, keep in mind that installing a roof ridge vent can cost anywhere between $500 to $1000, depending on your roof. Moreover, if you have an old house, you will also have to spend extra on the soffit ventilation system. This can increase the overall cost of installation.
Hence, if you plan to install roof ridge vents, keep some extra money on the side as the installation is costly.

List Of The Cons Of Roof Ridge Vents
1. Ridge vents do not always provide the proper ventilation in some homes.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.
If you dont have baffles installed with the vent, then this option may create zero ventilation even when the flow of air is correct. You must prevent outside air from crossing over this product for it to work effectively. Thats why most installations place shingles over the roof.
2. 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.

Proper Roof Ventilation: Ridge Vents Or Power Vents
On the surface, roof ventilation sounds ridiculously simple: out with the hot air, in with the cool. The goal is to get rid of the stale, hot, and humid air in your attic and to continuously replace it with fresh, cool air from outside. Done right, roof ventilation can cut cooling costs in summer and heating costs in winter as well as prolong the life of your roof.
But the question of whether to install a ridge vent or a power vent isnt nearly as simple.
Some of the arguments in favor of ridge vents include: passive ventilation , reliability , ease of installation, and relatively low upfront cost.
On the other hand, power vents are a better choice for hip roofs and for homes in the Northeast, where fluctuations in winter temperatures can sometimes make passive venting impossible.
In either case, there needs to be a balance between intake and exhaust as well as adequate attic insulation. But, as Anderson SC roofing specialists will tell you, there are other factors to consider, like existing vents, attic and ceiling shape, roof pitch, and obstructions.
Long story short, the choice between a ridge vent and a power vent isnt as cut-and-dried as most homeowners imagine. Whats definite is that it should remain an either/or question. Combining the two is a bad idea, as Danny Lipford explains:
Combining an attic power vent fan with a ridge vent is usually not recommended because:
Not Effective For Flat Roofs
If you have a flat roof, then you might want to reconsider getting roof ridge vents. It is because these vents are built keeping in mind the slanted roof. So, they wont work effectively with flat roofs.
Moreover, for full efficiency, you need to get them installed on the peak of the roof. If not, then it can again hamper the working of these vents.
Lastly, you can either get a vent installed on only one ridge or multiple ridges but keep in mind that in the case of only one ridge, the performance is affected too.

Allows Natural Exchange Of Air
A great thing about roof ridge vents is that you dont have to put in extra effort, as the whole air exchange process is quite natural.
As the hot air rises, it escapes in the outside environment due to the pressure difference. Once the hot air escapes, it also facilitates the movement of fresh air inside the attic.
So, in the whole process, you dont have to look or worry about anything at all.
