Top Reasons You Can Have Winter Flooding
Winter flooding may sound like an oxymoron. However, flooding can occur in the winter when water drainage is altered and the ground is over-saturated with water hence large amounts of water remain on the ground for longer periods resulting in winter flooding. The most common areas prone to flooding in a home are the basement and the attic.
During winter the probability of having snowstorms is high and the large amounts of the snow pile up within homes and gardens. When the melting of the snow starts then the problem of flooding is likely. The winter always leads to the ground to freeze and get over-saturated with water hence no more water is not allowed to penetrate the ground causing accumulation of water o the surface that results in winter flooding. Snows always heap within the unlikely places for instance around the basements hence after melting there is a challenge in draining the water since the water from snows do not have a way to flow like the normal rainwater. In addition, if your yard is graded improperly and sloping at a negative grade against the foundation there is nowhere for the snow to go and compound the flooding problems.
Frozen and Broken Pipes
During winter, pipes within the coldest areas of a home like the attics and basements are predisposed to freezing, especially those that are located close to exterior walls. When freezing occurs within water pipes pressure builds up hence causing a pipe to crack or burst. Water will come out from the pipes and this may be in large amounts if melting occurs hence the possibility of winter flooding. It is vital to prevent the pipes from freezing for instance through insulation, maintaining warm temperatures within the house, sealing holes that let cold air into the house and allowing trickling of the water through the faucet.
When rivers and other water bodies are exposed to long cold periods the likelihood of freezing of the water surface is high. This occurrence leads to ice jams that form a breeding ground for winter flooding. Flooding may occur during the melting of the ice since the breaking down of the ice causes a rise in water levels within a short time and the river cannot handle it.
Apart from ice jams that clot the rivers ice dams may occur whereby melting ice and wsnow may refreeze within the eaves of the roof. When warm air rises to the attic melting can occur resulting in a pool of water trapped in the attic. Melting and refreezing continues within the roof shingle and apart from resulting to floods the ice dams can lead to other damages like rotting of ceiling and growth of mold within the house.
High strong winds can cause and accelerate flooding during the winter period. High winds lead to wide-spread tidal flooding and also encourage erosion of the beach. When the winds are strong enough then they may raise water levels and cause storm surges that can result in flooding. Strong winds accompanied by snowstorms (blizzards) during the winter are enough to cause flooding within homes when an increase in temperatures leads to the melting of the snow.
It is important to employ preventive measures that prevent winter flooding within the home. Homeowners predisposed to winter floods can seek insurance coverage that will help in repairing their homes in case of damages.
