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.
On a 100-degree day, an attic can reach temperatures of 170 degrees or more due to the radiant heat effect.
An unventilated attic can reach 150 degrees in the heat of summer -- 50 degrees higher than it should be. An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate.
If your attic temperature is consistently hitting 130 degrees or hotter, damage to your home and a high utility bill is very likely. You can keep a thermometer in your attic to check – it doesn't have to be an expensive one and will give you a better idea of how hot things really are.

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.
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.
The inside of a car acts like a greenhouse, where actual temperatures inside the vehicle can reach 120°F in minutes and approach 150°F in as little as an hour!
Professional roofing contractors generally agree that while roofing projects can be done at any temperature, most experts advise against roofing when the temperature drops below 40 degrees or climbs to higher than 85 degrees.
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.
To cool down an attic room, you can use preventative measures like installing heat protection windows and insulating blinds, or reactive methods like fans and improving ventilation. A combination is the most effective way to beat the heat!
Hot air rises, just like your energy bill will do if your attic is poorly insulated. A poorly insulated attic can result in 25% heat loss in fall and winter—that's 25 percent of your average heating costs going toward energy that won't even heat your home.
The two species that have no issue with the heat of attics are bats and snakes.
Incorporate Under-Eave Vents
Also known as soffit vents, under-eave vents are crucial for drawing in fresh air and setting up the cyclical air flow necessary for optimal attic ventilation. They work hand in hand with ridge vents. As fresh air enters through the soffit, it pushes out the hot air via the ridge vents.
Well, potentially - but not really. Your car may feel like a sauna in summer. However, the heat is probably not distributed evenly enough to eliminate all bed bugs and their eggs. The dashboard might be sizzling, but the bed bugs hide in cooler spots like under your seats.
Generally, at temperatures above 89° Fahrenheit, most dogs are at risk of heat stroke, and you should avoid walking your dog when it's 90°F or hotter. For many dogs, outdoor activity at temperatures above 82°F can be dangerous, and for some dogs even temperatures in the 70°-77° range can be too hot.
A lot of drivers still swear by the old practice of leaving a car's side windows or sunroof open a crack to keep their vehicle's interior temperature down. This does let the built-up heat escape and helps to facilitate some airflow through the car's cabin, but only a fairly modest amount.
Tips for Keeping Cool During Sleep
A cool or lukewarm bath or shower can help with that, suggests Raymann. For most people, the temperature in the bedroom at night should not exceed 72 degrees Fahrenheit, and it should be even lower for people that sleep best in a cool bedroom.
The Egyptian Sleep Method is pretty simple: sleepers wrap themselves in a wet towel when it's too hot to slumber comfortably. This trick supposedly dates back to ancient Egypt when they didn't have the modern conveniences to help them with the high temperatures.
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.
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.
Working in an attic with an internal temperature of 100°F+ will inevitably result in increased perspiration and a huge loss of body fluid.
