Maybe you're upset about a roof leak. Or worried because there is something wrong with your shingles like: missing shingles, broken shingles or worn out shingles. Or maybe you are concerned about roof damage caused by a wind or hail storm. Maybe you became alarmed because you looked in the attic and saw condensation or mold growth. Or you could be afraid something is wrong because the wood under the shingles is rotted. Some homeowners are fortunate and realize that their roof is worn out and get it replaced before problems occur.
