Different kinds of debris, such as fallen leaves, small branches or various splinters have a tendency to gather on the roof. They usually accumulate around the chimney, on the valley or on other roof corners. This debris prevents the rain water from draining. The extra humidity ruins the roof and little by little it it loses its integrity. To avoid this, it is recommended that you clear the debris at least once a year.
Every house owner wants to have a beautiful environment around the house and plant lots of trees. But it is recommended not to plant trees near the house, as otherwise the leaves and branches fall straight onto the roof and ruin it. If the trees are already there, it is recommended to trim any branches near the roof every year. Also, huge trees cast shadows which could provoke roof rotting.
