It’s important to note that some granule loss is considered normal and does not necessarily indicate a serious problem with the roof. However, excessive granule loss can impact the shingle’s performance and lifespan. If you notice a significant amount of granules accumulating in your gutters or downspouts, or if you see large patches of exposed shingle surface, it might be a good idea to have a professional roofer inspect your roof to assess its condition and determine if any action is needed. Regular roof maintenance can help extend the life of your shingles and prevent major issues down the line.
