Your roof is an integral part of your home's security. Damaged or missing shingles are a sign that your roof may need replacement. We suggest that each spring and fall you take the time to inspect your roof and eavestrough. This will allow you to clean out your gutters and foresee any problem areas where potential leaks can develop.
