If your roof has experienced damage, whether due to age or a recent storm, it can be hard to know what to expect without the guidance of a roofer. Can you get by with simple roof repairs, or will you need a whole new roof installed?  To help you gauge the extent of the repairs needed, the following information should help you understand whether or not you need a new roof.

When You Need Roof Repairs

You can likely get by with only minor repairs if the roof is in generally good shape but features small or localized areas of damage. For instance, if a tree branch has fallen and punctured the shingles and roof deck, a roofer can patch this hole without the need to re-shingle the whole roof. Alternatively, if a storm has blown off patches of shingles in a few different areas, a quick repair job can normally solve the problem. As long as the shingles and decking are in decent condition, problem areas can generally be fixed or patched.

When You Need a New Roof

Whatever the damage, you'll probably need a replacement if the roof is 20 years old or more. This is the approximate lifespan of asphalt shingles, so if you notice general deterioration such as curling edges, discoloration by mold or algae, or granule loss at this point of age, it's a sign they are at the end of their life. Also, if the structure is sagging or bowing, it means the decking—the wooden sheets to which the shingles are attached—is weakening, either due to age or water damage. Under these circumstances, you should have a new roof installed.
