Most people don’t hop up on their roof on a regular basis or even think about their roof for that matter. Unfortunately, neglecting your roof can lead to serious damage and costly repairs. So how do you know if you might need a new roof? Keep an eye out for these 10 Warning Signs.

1. Missing Granules​

  • Small amounts of granules will be loose after application of a new roof.
  • On older shingles, missing granules indicate a need for replacement
