What are some signs that my roof may have problems?

There are some signs that are obvious and others that are not.
Some common roofing issues you typically can see are missing shingles, water stains inside of the home, and exposed roof components that look out of place.
Concerning issues such as rotting plywood, cracks in a pipe collar, flashing issues, or water penetration traveling through the attic, are a few examples of issues that most of the time, only professionals will see during a thorough inspection. Which is why, having your roof inspected periodically is crucial.
