Occasionally inspecting the condition of your roof can save you the expense of replacing the entire roof later. If your roof is fifteen years old or more, chances are it needs to be repaired. Look for damaged or moldy shingles, or shingles with bare spots. These can lead to leaks, stains, and rising energy costs. Check to make sure the flashing is connected to the roof in the proper areas, such as valleys, skylights, eaves, chimneys and stacks. The flashing can pull away from these areas because of dried caulking or severe changes in temperature. Taking time to inspect your roof now can help prevent costly replacements in the future.
