By covering roof vents you ll trap moisture and warm air.
Should i cover roof vents in winter.
For every two percent moisture you lose a third of the r value.
Roof vents ensure air properly circulates throughout the attic ventilating your home as it exits through the roof.
During the winter roof ventilation works to keep temperatures even.
So those vents actually help keep that insulation dry in the winter time.
A drafty attic is a very good thing.
But if you needlessly increase your roof penetrations you run greater risks.
If you have your insulation and you let it get two percent damp it loses one third of its ability to insulate.
Although there are many types of vents all of them play a key role in keeping your home well ventilated and your roof healthy.
Closing your vents makes the attic space too warm and dry dangerous conditions for mold as well as pests.
Roof vents create additional access points for moisture to seep in and leaks to occur.
Just as with space too much or too little space will cause major problems.
Blocking the vents can even harm your home by trapping moisture inside the attic.
Roof vents allow air to circulate through your attic and exit your home.
Without proper air circulation your risk of structural and home environment damage increases.
This can lead to the growth of mold which can cause potential health problems.
The same can be said of roof ventilation.
In the winter the vents will cause the attic to become cold but this should not damage your home or increase the energy use of your home so covering the roof vents is not necessary.
Even though vents can cause attics to become colder in the winter months they should still never be covered.
