Condensation In Attic During Summer

Extra heat build up under the roof deck can cause your shingles to deteriorate much faster sometimes cutting their life expectancy in half.

Condensation in attic during summer.

The concern in summer is heat. It will help reduce the moisture in the summer and in the winter time. If you have insufficient duct insulation condensate moisture can appear. If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck.

On hot days you may notice water droplets forming on your visible air ducts and wonder whether this is normal. Attic insulation and ventilation go hand in hand. How does condensation get in the attic. That s why wintertime condensation problems are fairly common.

For each relative humidity rh value there is a temperature value below which the condensation will start. It improves the overall comfort of your home. How to completely prevent condensation once you ve blocked the common entry points for air and thus moisture penetrating your attic space you can prevent moisture from accumulating in your attic in two main ways. In the summertime the attic is hot and humid and in the winter time humidity from cooking bathing heat travels up to the attic and condensation accumulates in the attic.

Condensation happens on cold surfaces and winter weather makes many surfaces cold. Summer is the time of year when your air conditioning unit has to work the hardest to cool your home. The main goal is to keep your attic temperature the same as the outside air temperature in the summer as well as in winter. This problem is especially prevalent in the summer due to how hot the air is.

Roof ventilation lowers energy utility costs during the hot summer protects the roof from rot and ice dams during the cold winter and extends shingle life. A humidistat can also be installed. They keep your home cooler in the summer warmer in the winter and free from damage caused by moisture. What you see is condensation also known as ductwork sweating.

Wherever your a c cooled air is entering may be cooler and when that muggy summer air contacts any cold surfaces you may notice the attic condensation problem. An excellent attic ventilation allows the outside air to move in freely through the attic which in turn provides many benefits. If you set the air conditioning temperature higher then the temperature of the return air will also be higher and there will be less chance of sweating at the ahu.

It happens during the summer. Also if the duct boot the part that connects the duct to the vent is not sealed properly or is loose for any reason condensation may appear. Why is that important.
