Many wonders, “Is the temperature in my attic bad for my home?” In short, the answer is yes. Hot temperatures in your attic can damage your home. They can also make it harder to control the temperature in the rest of the house.
Not only can this have an impact on your comfort levels, but it can also lead to higher energy bills. Heat in the attic can be a contributing factor to harmful mold growth. Mold growth happens particularly if the heat is accompanied by humidity. It can also damage your roof.
On a 100-degree day, an attic can reach temperatures of 170 degrees or more due to the radiant heat effect.
By improving ventilation in your home's attic, installing an attic fan can help reduce moisture and even lower the temperature within your entire house.
These essential systems can occasionally overheat and catch fire. The danger is more severe in the summer when your attic is already really hot. Dust and other debris build up in the ducts of these systems, adding to the likelihood and speed of a fire spreading.
An attic is one of the most common places where a fire can originate in your home. The Federal Emergency Management Administration (FEMA) estimates more than 10,000 attic fires occur in the United States each year, leading to an average of 35 deaths and $440 million in property damage.
The two species that have no issue with the heat of attics are bats and snakes.
Why are attic fans not used anymore? Due to inefficiencies in relying on existing attic vents for air intake, attic fans have lost popularity. These vents often aren't designed for this purpose, resulting in inadequate replacement air supply.
The ideal attic temperature should be no less than 60 degrees in the winter and no more than 10 to 20 degrees above the outdoor temperature in the summer. If your attic temperature climbs above 130 degrees, you may start running into issues with your energy bill, as well as the integrity of your roof.
So, how hot should your attic be? Ideally, the attic temperature should be close to the outside temperature, give or take 10 to 20 degrees. If your attic temperature is getting to 130 degrees or hotter, you can expect to see damage to your home.
Sleep experts believe the best temperature for great sleep is between 68-72 degrees Fahrenheit. But in addition to making you uncomfortable and interfering with healthy sleep patterns, being too hot at any time of day or night can cause health risks like dehydration and heat stroke.
Heat stroke is life-threatening and requires immediate medical treatment. The longer your body temperature remains high, the greater your risk of complications (like organ damage) or death. If you or someone around you has signs or symptoms of heat stroke, call 911 or your local emergency services number immediately.
Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor. Once they are in place, you can then place the batts or blankets, or blow insulation, right out to the very edge of the attic floor.
Note excessive heat – if it's 90 degrees outside, the attic temperature shouldn't be more than 110 degrees. More often than not, attic temperatures will be in excess of 125 degrees on a 90 degree day. This will overwork your air conditioning equipment, run up your utility bill and shorten the life of your roof.
There's no doubt attic ventilation can impact the effectiveness of the air conditioning system. Removing the built-up heat inside the attic that radiates from the sun baking the roof is essential. Otherwise, that heat can transfer into the living space which increases the burden on the AC system.
The primary function of attic fans is to promote airflow within the attic, which can help reduce temperature and moisture levels and provide several valuable benefits.
If the evenings are cooler, you can try turning the attic cooling fan off until the morning, but if you notice your HVAC system begins to struggle to keep your home comfortable, you may want to keep running the attic fan overnight.
By removing hot air from your attic, attic fans can help reduce the workload on your air conditioner, which can lead to lower energy bills. They can also prevent ice damming during the winter months, which can cause damage to your roof and home.
You don't need to have your attic fun running all of the time. Having it running only when it's needed maximizes its benefits for your home's AC and overall energy efficiency.
To prevent insect infestations, make sure that your boxes are completely clean and free of food remnants or crumbs that could attract all sorts of bugs. Be sure to avoid storing your corrugated boxes in a location that may have a higher risk for fire, such as an attic.
Bats like to roost in attics because they are hot, safe places to raise their young, called pups. They may have pups from mid-May to mid-August. The pups will begin to fly in July, but still need a safe place to roost for a few weeks.
However, while the attic may be warm and cozy for them in the winter, it may be too hot for them in the summer. Rats may have to move out of a hot attic in the summer, but that doesn't necessarily mean that they will leave your house entirely. Therefore, you may still need professional rat removal.
