All roofing materials will eventually deteriorate and erode. However, you can absolutely extend the life of your roof with proper maintenance. The mistake most homeowners make is to ignore small repairs as needed. A missing shingle takes little time and cost to fix; but ignoring that missing shingle may allow water to seep in, debris to accumulate and pry other shingles loose, or damage to affect the underlayment. Taking care of small problems can prevent the larger problems for decades.
