Long term exposure to condensation and moisture can lead to hidden plywood damage as well as damage to a home’s insulation.
St. Louis is experiencing one of the coldest winters in a long time. The frigid temperatures this polar vortex is creating are adversely affecting many aspects of life. For some homeowners, this includes damage to their home.
While most roofs are able to withstand extreme temperatures, hot and cold, some may not be as resilient. There may be a number of reasons for this. However, there are some common misconceptions that many homeowners have about the build-up of ice, ice dams, and the other affects of below-freezing temps and weather.
Cause of Ice Dams
A common misunderstanding concerning ice dams it that they form because roof shingles or other roofing materials are installed incorrectly or are defective. This is not the case. Ice dams are created when the cold air in the soffit meets with the warm air in the shingles which are situated above the soffit.
In addition, some believe that if they replace their asphalt shingle roof with one that has watershield and ice protection, their roof will no longer form ice dams. However, a new roof with this type of protection may be able reduce water intrusion, but no matter how new a roof is, it is made to shed water, not hold water.
Other Issues Caused by Winter Weather
One issue that crops up with severe winter weather is roof vents getting covered with snow and ice. When this happens, the snow or ice will trap heat in the attic. When the heat is not allowed to escape from the vents, it warms the air in the attic and creates a winter green house effect, thus causing ice dams.
Further, if you see water or ice dripping out of the siding or soffits, this is actually coming from the underside or inside of your roof sheeting. This is an indicator that you will soon have a leak on the inside of your home.
Unseen Damage from Winter Weather
Ice dams can create damage that it not always apparent. Long term exposure to condensation and moisture can lead to hidden plywood damage as well as damage to a home’s insulation. Insulation that dries but loses its R-Value, will let excessive heat into the attic which will accelerate the ice damming process, causing even more damage.
