Asphalt Shingles:
Composition shingles are probably the easiest of roof surfaces to maintain.
First off, the attic under them must be properly ventilated. If it is, then with regular maintenance the roof should last 20 to 40 years depending on the slope and the particular materials.
Clean all debris from the surface of the roof. Including debris that has gathered behind HVAC units, pipes and pitch pans, and any other roof penetrations. Debris has a tendency to hold water, and water will expedite roof deterioration, especially if your roof is asphalt based such as a built-up roof or asphalt shingles. If your roof is starting to collect moss or algae, install some zinc or lead control strips. Dab some roof cement under any loose shingle tabs. Clean all debris from the surface of the roof, and try to keep the gutters clean too. Above all BE CAREFUL! If you are not skilled at walking on your roof then don't. It isn't worth it.
