The roof is really an important component of your home because it protects and insulates your home from extreme weather conditions amongst other things. This means that with a good roof you do not incur huge bills at the end of the month because the house is well insulated. Inorder to ensure that your roof is in the right conditions throughout the year it is important to know how the different weather elements will impact your roof. Here are some of the elements and the effects they will have on your roof.
The sun is always shining on the roof for the better part of the year. This heat also has adverse effects on the roof especially when it is excess heat like it is during summer. Heat causes things to expand and when this happens it can cause damage to the shingles or the workmanship on the roof. When one shingle expands it can push the others out of their rightful place compromising most of the structure. Also expansion of the shingles could mean that they crack which could cause leakages into the house. Also the expanding and shrinking of the shingles will cause them to wear out quickly. To counter this problem you should ensure that the roof is very well ventilated so that the excess heat gets out of the attic and hence away from your roof. There are also roofs that are made to reflect the heat of the sun away which ensures that they remain cool.
Snow can cause the roof to become heavy when it accumulates on there. This depending on the weight of the roof can cause it to cave in. Also this increment in weight of the roof causes the structure to become weak and wobbly. Snow also causes leakage and moisture build up because it can easily seep through the cracks as it melts. Snow is also know to cause ice dams which occur when snow inhibits proper flow of water from the roof causing it to leak and accumulate inside the house. This can cause major water damage to your property requiring expensive roof repairs.
When strong winds blow over your roof, they reduce the pressure on the roof way below the pressure below the roof. This difference in pressure is what causes the roof to be pushed upwards. This can cause the roof to be blown off. It can also cause the nails holding the roof and the entire framing structure to become loose. Strong winds also carry debris with them and can deposit this on your roof. Winds will also cause the shingles to move and get misaligned. When this happens it is possible for your house to be exposed to the elements.
