All of us Homeowners understand the erratic weather with which we deal from the time winter hits all the way through to the sunny Spring. We all know that we need to remove all icicles right away. Icicles are a tell-tale sign that water has already, or will, enter soffit areas, siding, window areas, and especially where the roof meets up with a wall or chimney. Another part of our Maintenance and responsibility as Homeowners is to try to rake/shovel eaves and edges of our roofs. A great extension roof rake can be found at most hardware stores. There are companies for hire that offer roof shoveling as well. Step 1 is always to remove the snow and ice from your roof!
However, there are a handful of contributing factors to interior moisture that we may not be aware of. If water is seen inside your house, and it is winter, you will now know that what you are experiencing is not a roof leak.
This time of year, warm garages or homes meet the cold from outside and form a white frost/snow-like material on the underside of the roof-deck. When the frost warms from the heat of the home or garage, it will drip downward.
Besides ice dams that are well publicized in Minnesota, there is an abundance water that sneaks into the underside of soffits and turns to a solid frost form. However, this is only one culprit of frost and condensation in the winter.
Ventilation is a wonderful thing. Air Vents and Ridge Vent work great when it comes to regulating humidity, especially in the warmer months. However, vents are designed to be open and sometimes air leaks, condensation, or frost will exist.
Normally roof deck leaks will show their heads during the rainy seasons and will be noticed immediately after construction. That being said, moisture seen on ceilings, light fixtures, fan areas, windows, doorways, window screen areas, etc. is all coming from the inside, not the outside of the home.
Some factors that may be accelerating your home’s interior condensation are showers, humidifiers, wet towels, cooking, bricks/chimneys, window condensation, and skylight condensation to name a few.
These links will help explain the frost and condensation this time of year. Also remember that snow is an insulator and will rapidly contribute to the presence of frost.
