Wind – The Unusual Cause of Roof Leakage
Roof leaks are common after heavy rainfall and storms. It is a big cause of concern for homeowners, as it not only damages roofs but can be damaging to vents and walls as well. So, when a person observes roof leakage they rush to call roof contractors to stop more damage. But it is very important to understand that roof leakage is not always as damaging. Let’s try to understand it in detail.
There can be different reasons for roof leaks. Usually missing shingles and blocked drain pipes allow water to stay on the roof for a longer time. The water seeps in and finds some crackers and you experience Roof leakage. But sometimes it’s not the serious situation as it seems. The angle of the rain can lead to roof leakage, which is not as damaging.
To understand this, you need to understand the construction and structure of the roof. The roof has shingles as a protective layer and the roof is designed to drain the water which pours vertically. It means when rain falls on the roof, shingles protect the roof, and water is collected in the drainage system and it leaves the roof through a drainage pipe. But sometimes, rain is wind driven. You might have experienced this rain which falls on an angle. Instead of vertical fall, due to wind, it falls horizontally. In this situation, it hits those areas which are not the usual target of rainwater. The roof is not designed for this type of rain, as it’s not very common. So, the rainwater reaches below the shingles and to that part of the roof which is prone to leakage. Sometimes the angle is slightly horizontal and you see a wet spot, but sometimes the angle of rainfall is so perfect that the roof starts leaking.
But how will you judge if the leakage is serious or just rain driven? The simple solution is to observe if it leaks during every rain or if it’s very rare. If you experience leakage after every rain, it’s good to call a roofing contractor and let him inspect your roof. They will do a professional inspection and check if there is any damage to the roof structure and fix the issue before it becomes serious. However, if you observe leakage rarely, it can be due to wind-driven rain and there might be nothing to worry about.
