It is 95°F outside and the house is kept at 78°F. A properly vented attic should only reach about 105°F in this situation, thus creating a 27° temperature difference between attic air and conditioned air. An improperly vented attic could reach a temperature of 160°F, thus creating a 82° temperature difference.
On a 100-degree day, an attic can reach temperatures of 170 degrees or more due to the radiant heat effect.
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.
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. An attic can easily surpass this target in warm climates, getting as high as 160 degrees in the summer.
In fact, if the air temperature is 95 degrees — which it was on Thursday in Miami — after ten minutes, the temperature inside a car rises to 114 degrees.

Key takeaways: The highest environmental temperature humans can survive is 104°F to 122°F (40°C to 50°C). But those temperatures aren't safe. A safe temperature range for prolonged outdoor time is 77°F to 88°F (25°C to 31°C).
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.
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.
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.
Due to their nature, attics are prone to overheating, even in the UK! Heat rises to the top of the house and gets trapped under the roof. Roof windows also mean plenty of sun throughout the day. All this can cause an uncomfortable attic temperature, especially during hotter months.
If it's 90 degrees outside, most people would set their AC to a perfectly comfortable temperature of 68-72°F.
Research shows sleep can be disrupted by temperatures anywhere below 65 degrees Fahrenheit or above 75 degrees Fahrenheit. But for most people, heat interferes with sleep more than cold does. Sleep experts believe the best temperature for great sleep is between 68-72 degrees Fahrenheit.
Install electric ventilators and attic fans, which remove hot air from an attic. They have thermostats that turn the fan on at a recommended preset temperature of 100-110 degrees. Alternatively, install passive vents such as gable, soffit and ridge vents, which are openings in the roof that allow hot air to escape.
The two species that have no issue with the heat of attics are bats and snakes.
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.
The short answer, yes, insulating the attic is an effective way to keep your home cooler during the summer months. While it's a given that the insulation in your attic will keep the home warmer during the winter, it isn't immediately obvious that insulation can also help to keep the home comfortable during the summer.
If you had to choose just one—and your attic has a great need for ventilation—an attic fan is your best bet. Attic fans in the $300 to $400 range can move upwards of 5,000 CFM. For lower capacity ventilation at a steep cost savings, a ridge vent might be your best choice.
Electrical malfunction is the leading cause of residential building attic fires (43 percent), followed by natural fires (16 percent). A third of all residential building attic fires spread to involve the entire building.
What forms of heat transfer are occurring when an attic heats up on a summer day? Primarily, radiation is what causes warm attic spaces.
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.
West Virginia and New Jersey are the only states that criminalize the act of leaving a pet unattended under dangerous conditions without providing a rescue and immunity provision for anyone.
Key takeaways: Temperatures above 85°F are too hot and below 32°F are too cold to keep your dog outside for long. You can take precautions to keep your pooch safe, like checking hot pavement with the back of your hand or wiping snowy paws with a damp rag. Extreme hot and cold weather can be dangerous to your dog.
On the climate controls screen, touch Keep Climate On, Dog, or Camp. You can also control Dog and Camp from the mobile app, by swiping up from the gray bar on the Climate screen.
