Most professionals will recommend increasing ventilation in your attic if ventilation is inadequate.
Do attic vents improve humudity.
The normal indoor humidity range in winter should be 15.
These vents allow for a cross breeze through your attic blowing out the warm air and replacing it with cooler less humid air.
Rafter vents or insulation baffles install in any rafter space to create narrow gaps that direct fresh air from the soffit vents to the peak of the roof.
This may increase condensation and lower the effectiveness of the insulation.
Having roof or attic ventilation will also help decrease your power costs as well so all in all this should save you money.
However this often does not solve the problem.
Humidity settings are another issue that can make or break the performance of your heating and cooling systems and your attic ventilation.
With no air conditioning vents pumping in cool air and the hot sun beating down on the roof right over your head attic temperatures can soar.
Only about 10 of the hip roof is shaded so it gets plenty of direct sunlight.
Advani hopes to finish the attic and install a minisplit although he s not sure that will lower the humidity.
Unless you have a finished attic you probably aren t fond of spending time up there during a hot summer day.
I ve had mold growth on our drywall and cabinetry in our main living area simply by keeping the windows open and not using the ac during the summer.
With outside temperatures ranging between 5 f and 95 f attic temperatures range between 48 f and 92 f.
However if the heat and humidity enter the attic through the vents during the summer and the air isn t being circulated then that is a prime condition for mold.
But with proper ventilation you can at least bring those temperatures down to match that of the outdoor air.
