The roofs are regularly exposed to the weather elements that cause aging. The Ultraviolet rays from the sun can thrash the roofs which cause them to become worn out immediately. The weathering of the roof will quickly have water leak due to the snowfall or ice dams. Continuous rains will even result in drainage of moisture causing the buildup of moss which weakens the roof area and towards the end such developed moisture gets into the wall surfaces damaging them.
Assessment of your roofs can be performed on your own or by using the services of a roofer to perform an in depth check. If you are planning to perform the assessment of the roof on your own there are also many things you must find like any broken or outdated shingles on the roof, is there any buildup of granules as well as other particles in the drains of the gutter and any indications of moisture leakage on the walls as this moisture will cause the buildup of moss and also mildew.
