Water found in these places is commonly caused by condensation in the attic.
Roof sweating in attic.
What causes water condensation.
The intent of roof venting varies depending on climate but it is the same if you re venting the entire attic or if you re venting only the roof deck.
This is not workmanship related or an actual roof leak.
If left untreated it can damage critical structural elements of the home such as the trusses and rafters ruin insulation damage any stored belongings and lead to the formation of potentially toxic black mold.
Generally this is not considered a do it yourself job and is best done with the help of experts in roof condensation and ventilation.
Fixing this issue can be less costly than replacing a roof but it should be addressed as soon as possible.
How does condensation get in the attic.
Most people assume this is caused by a leaking roof but that might not be the source.
Excessive snow on the roof attic condensation and ice buildup can cause roof damage water damage and personal injury.
In a cold climate the primary purpose of ventilation is to maintain a cold roof temperature to avoid ice dams created by melting snow and to vent any moisture that moves from the conditioned.
In the real world this means moist air from your house coming into contact with the underside of your cold roof tiles or the side of your water tank etc.
While we associate this condensation with attic areas it can actually occur throughout the roof assembly.
Moisture accumulation is most significant when outside temperatures are very cold because air holds less moisture as the temperature decreases.
If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck.
While stopping a water leak or repairing a washing machine hose down in the basement might be fairly straightforward snow on the roof ice dams and attic condensation are forms of water damage typical to cold climate homes.
Wet streaks and drips remain the best signs but sometimes thermographic imaging is the test that identifies the issue.
Condensation comes from the moisture in the air and.
To prevent frost condensation from developing in your attic you must eliminate or reduce the amount of air leakage into the attic as well as improve insulation ventilation to allow moist air to escape the roof.
You can prevent these problems from occurring by maintaining a dry attic with a low relative.
Condensation will form in your attic if warm moisture laden air comes into contact with a cold surface.
