How do I know if my roof has problems?

In most cases, roofing problems are discovered after damage has occurred from a leak. You may see excessive granules running down the downspout, shingles in the lawn, or excessive curling and cupping of the shingles on the roof. However, not all leaks produce visible damage immediately. Some leaks can occur for up to a year before showing any signs of damage. To avoid this hidden problem, it is important to have your roof inspected at least every five years by a qualified person.
