A. Semi-annual inspections need to be performed (usually before or after the rainy season) to check the asphalt shingles and all flashings surrounding such roof projections as chimneys, skylights and vents, etc. and make sure that they are not deteriorated or loose.  This can be done with the aid of a telescope. If it needs to be repaired, call a local qualified contractor to perform the work. (Try to avoid climbing onto the roof yourself.)

B. All fallen leaves and debris gathered in the eaves gutter need to be cleaned annually and make sure that the downspouts are draining properly.

C. Check if you need to trim back any tree branches overhanging the roof.  Overhanging branches may fall to the roof to cause damages or block out sunlight with too much shade formed, which prevents moisture from circulating out and promotes the growth of moss, thus the service life of the asphalt shingles could be reduced.
