Very Hot Attic

According to agricultural engineer b r.

Very hot attic. And that s way too hot for your electronics to survive. 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. There are soffits all around free of debris along with 8 square static roof vents.

Of course ventilation is important but did you know that many attics are not properly ventilated regardless of your homes age. I did some calculations and ventilation is sufficient. Despite all that the attic gets very hot probably 140 when its 90 and sunny outside. Whether it s 110 f or 130 f there s not much difference in the amount of heat flowing from the attic to the living space below.

Just make sure the ceiling is airtight and fully insulated and the temperature in the attic doesn t matter much. If your attic is hot and stuffy there are lots of ways you can cool it down. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. So here is what you should look for when determining your attics ventilation status.

A hot attic is bad for several reasons. This results in higher cooling bills and the need for thicker insulation above the ceiling. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer. Excessive heat deteriorates items.

In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth. Get creative with your roof dark roof shingles absorb sunlight and convert that energy into heat. If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage. When it s hot outdoors it s hotter in your attic.

The top reason your attic is so hot is because of ventilation. Stewart attics without air conditioning can reach up to 160 degrees fahrenheit on a hot day. Another problem is any ducting in the attic will be heated and the heat will transfer into any the duct and warm any cool air moving through it and into the home. It s only natural that your attic will heat up as a result.

High temperatures inside your attic shorten the life span of shingles.
