Installing a roof is not all that needs to be done to enjoy a beautiful roof at home or your place of business. You must carry out routine maintenance where you do things like cleaning and inspect the roof to make certain that it is in tip top condition.
For some strange reason, many people like to hang on their roof perhaps, to get an aerial view of their neighborhoods. It is highly frowned upon because the roofs materials may not handle your weight well and you may end up damaging it regardless of the material the roof is made from. Note that clay or slate tiles and asphalt shingles can become loose or crack when a person steps on them.
