Roof turbines are more effective in winter than ridge vents Moisture buildup during winter months can lead to the growth of mold and fungus, things you don’t want in your attic. Since turbine vents work whenever there is wind irrespective of the season, they are more effective during winter.

Is ridge vent better than turbines?

While ridge vents win for their subtle appearance and functionality, turbine vents may be better in especially hot or humid climates where more dynamic airflow is necessary. If you are not sure which to use, consult a roof professional who can examine the needs of your home and draw up a venting plan for you.

What is the best method of venting an attic space?

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.

What is the most effective roof venting system?

Soffit Vents (Most Popular Intake Vent) Soffit vents are a favorite amongst home builders and roofers because they are unquestionably the most effective intake vent for the cost. If a home’s style allows for it, most new construction builders include soffit vents in their home’s blueprint.

Are turbine roof vents better?

Still, despite running the entire length of your roof, ridge vents are static and won’t move air the same way turbines do. As long as there’s a healthy amount of wind to power them, turbine vents will provide superior ventilation for your attic.

How effective are turbine vents?

They are incredibly effective at venting hot attic air, but there’s not always room for them. When an attic space needs ventilation but there’s no more room for ridge vents, turbine vents are usually the next best solution. They are very flexible regarding placement, and there’s almost always room for them.

Do turbine roof vents leak?

Turbine vents are a type of exhaust vent. They have fins that open when they turn in the wind, and this spinning action creates suction that draws hot, humid attic air outside. Turbine vents can leak, but you don’t always have to replace the vent.

What type of ridge vent is best?

The shingle-over-ridge vent is a nicer, more consistent look compared to the aluminum vents, which are very susceptible to leaks further down the road because all of the fasteners are exposed—they go right through the surface of the vent and into the roof decking.

Is attic fan necessary with ridge vents?

Combining an attic power vent fan with a ridge vent is usually not recommended because: It could reverse the natural flow of hot air out the ridge vent. If air is drawn in through the ridge vent while it’s raining, it might pull rainwater in with it, which could lead to leaking or mold in the attic.

Can an attic have too much ventilation?

It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.

Do roof turbines help cool house?

Roof turbines remove attic moisture and reduce the risk of costly roof damage. During summer months, turbines eliminate hot air from your attic, helping you cool your home.

Are ridge vents worth it?

In addition to allowing air to circulate, a ridge vent on your roof prolongs the life of your roof. It also helps to moderate the overall temperature of your home, increasing your energy efficiency. For these, and other, reasons, roof ridge vents are considered an essential part of most modern roof design.

Do powered attic ventilators work?

Although power attic ventilators can provide relief in the summer, how they go about doing that is often not ideal or cost-effective. For one, they can steal air from the conditioned space of the home, forcing air conditioning units to work harder, use more energy and, therefore, raise utility bills.

How long does a turbine vent last?

A single 12-inch-diameter turbine vent can provide a complete change of air in the attic space every 52 minutes if the outside breeze is just 5 mph. A 14-inch diameter unit can provide a complete air change in the attic every 14 minutes if the wind is 15 mph.

Should I cover my roof turbines in the winter?

You should absolutely leave your roof vents open during the winter – do not cover them! During the winter, roof ventilation works to keep temperatures even. Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.

How do turbine vents keep water out?

The rolled edges are designed to force the water to run down the vanes & not into the attic. Air-foil means a body designed to provide a desired reaction force when in motion relative to the surrounding area. To summarize, the turbine should be turning at all times when there is outside air movement.
