Why Is Proper Attic Ventilation Important In The Summer

How to Vent a Bath Fan Through the Roof | This Old House

In the warmer months, your attic can get very hot. If its not properly ventilated, it can heat the upstairs of your home to the point where its uncomfortable. It may even get too hot to be upstairs at all during the day, only cooling when the sun goes down.

In the summer, your vents should be pulling in fresh air and allowing the hot air to escape. If the temperature outside is 90°F, the temperature in your attic can get as high as 170F.

If the temperature inside your attic is 170F, then the heat at your attic floor can be as high as 140F. The temperature in the rooms below your attic will be uncomfortable. Your AC will have to work harder to try to keep your home cool which will cause your energy bills to rise.

Poor ventilation in the summer can cause heat to build up in your attic which in turn burns your roof up. The roof decking can delaminate quickly. This means the adhesives in the decking has deteriorated and causes it to become brittle. It also causes your roofs shingles to become brittle, crack or curl.

Making sure your attic is properly ventilated will help you get the full life out of your roof.

When To Call A Professional

If you plan to install the vent yourself, be sure you’re really up for the challenge. This project requires work on a tall ladder and working atop the roof while using hand and power tools. If you have any anxiety over heights or are not quite sure you know how to handle your tools, consider hiring a professional.

Be aware that a ridge vent is only one part of properly ventilating your attic space and roof. For a ridge vent to work properly, it relies on passive airflow, or intake air, coming into the attic space via soffit or gable vents or other attic ventilation.

    What Does Attic And Roof Ventilation Do

    Attic ventilation is an important part of the way air flows through your attic, pushing it through the area instead of just letting it sit stagnantly. Roof vents help outside air pass through and out of your attic, which removes excess heat and moisture from the air inside of your attic as it moves through. Air is taken in through your roof soffits and eaves, exhausted through the roof at the ridge cap or through a roof vent. This creates the right air balance in the upper crawl space of your home, playing an important role in keeping your home comfortable and increases the quality of living indoors.

    How To Determine The Amount Of Ventilation You Need

    Before installing any roof vents on your home, determine the amount of ventilation youll need. You can check if your attic is underventilated by following these four steps:

  • Look at your roof and the eaves. If you dont see any vents, you should definitely add a few. Some vents look different than traditional roof vents, though, so also keep your eye out for ridge vents, which are low-profile vents that run along the peak of the roof. Your roof may also have gable vents, which are louvered openings at the top of the gables.
  • Inspect your attic during the winter using a flashlight. Warm air contains moisture that will condense on a roof sheathing or rafters if it escapes from the living spaces in your home. If you see frost or dampness, you need better ventilation.
  • Check out your roofs eaves during the winter. If there are thick ridges of ice on them, it could be a sign of underventilation. Warm air could be escaping from rooms in your home and getting trapped in the attic. This can cause snow to melt and refreeze on the cold eaves, which creates ice dams.
  • Wait until a warm and sunny day, and then touch your ceiling to see if its hot. If it is, it may be acting like a solar oven, overheating your shingles and increasing your energy bills.

    Why Is Proper Attic Ventilation Important In The Winter

    Roof Ventilation: Intake Vents vs Exhaust Vents

    When I tell people that proper ventilation is more important in the winter than it is in the summer, they are always surprised. What most people dont know is that heat and moisture from the homes interior travel into the cold attic, which causes condensation and all the problems that can come with that.

    Condensation collects on the underside of the roof which then causes the decking to swell. If the decking holds onto this moisture, it will become wavy. If the decking is wavy, guess what? Your roof will also be wavy!

    Because the decking is wet, over a short period of time, it will also lose its ability to hold the nails and may lose its load bearing capacity. This can also cause mold and mildew which can contribute to serious health issues.

    Plus, moist wood rots. And insects such as termites love moist, rotting wood.

    Are Powered Roof Vents Worth The Cost

    How To Install a Vent in Shingles

    Powered roof vents or attic fans work with a thermostat. When the heat builds up past the setpoint, a fan turns on, venting the warm air outside. While some people have these installed on their home roof to keep the attic from being too hot, they have downsides there, as they can fight with air conditioning.

    For a shed, you need to have electricity run to your shed. You also may not be able to tell if the fan has stopped working unless you find that it just wont go on even when you adjust the thermostat.

    Solar-powered models are available, but you can have really hot days that are too cloudy to allow the fan to work, rendering them less than useful. Also, many models tested really dont move that much air.

    Actually, powered roof vents were designed to keep attics from getting too hot, not for cooling a shed. There really isnt enough advantage in using one for your shed to justify the cost, even if you already have power run to your shed. Non-powered solutions will do just fine for a shed.

    Best Van Roof Vent Fan

    There are numerous, but to keep it simple here were just going to compare the top three camper roof vents on the market Fiamma Turbo Vent, Dometic Fantastic Fan 7350 and MaxxAir MAXXFAN Deluxe.

    Each make and model has different features such as an automatic rain sensor, remote control, adjustable speeds and climate control. But they are all electric camper vent fans, because really thats the only way to go.

    We opted for the MaxxAir MAXXFAN Deluxe 7500K mainly because it can still be operated in the rain. As opposed to the Dometic Fantastic Fan 7350 which just automatically closes and shuts off in the rain. But then needs to be manually turned back on.

    Being in the rainy UK, it seemed like a pretty essential feature. We dont, but if you travel with pets that you intend to leave alone in the van, a van roof vent fan that has both thermostatic climate control and can be operated in the rain is crucial.

    You also have the choice of a white or smoked lid with the MaxxAir MAXXFAN Deluxe.
