  • Neighbors are getting new roofs. Homes built around the same time period can be experiencing the same types of weather conditions can mean that your roof is nearing its useful life.

  • Moss can grow on roof surfaces that dont get much sunlight, especially in cool, moist climates. Moss growth can be more than a cosmetic issue. Moss holds moisture against the roof surface and overtime in freezing climates can cause damage to the granules on the top of the shingles. Moss can be brushed off but it wont prevent it from growing again; take care not to damage the shingle surface. You may need to contact a professional roofing contractor.
