The roof is a very important part of the house. It protects us from the scorching heat of the sun, the shivering snow, and the rain in every thunderous storm. Without the roof, the house would not be complete.
Unlike the walls which can be seen all-around the house, or the floor that you literally step on, the roof does not garner that much attention compared to these parts of the house. Because of this, the roof gets lesser attention over time. Because of the unawareness of homeowners, small roofing problems become major ones that require a more money to fix rather than a few tools and effort.
