It may be out of sight, out of mind, but here are five signs you may need to replace your roof, offered by the Metal Roofing Alliance:

• High winds have removed shingles from your roof, creating an invitation for leaks. Use binoculars to inspect your roof without a ladder.

• Shingles that are obviously cracked or peeling. Even if the shingles aren't missing, if they're curling or torn, they're on their way to failing.

• Stains or water marks on your ceiling, which can indicate a leaking roof even if you don't see a puddle. It's important to find the source of the leak and make repairs before the problem grows.

• Discolored shingles, which can be a sign of mold or algae growth on your roof, particularly in warm, wet climates. The elements are hard on a roof, and can cause it to deteriorate and fail.

• Age. If you have a typical asphalt-shingle roof and it's more than 10 to 15 years old, chances are you're going to need to replace it in the near future.
