Those black granules are likely from your asphalt shingles. In Bozeman's climate, with intense sun in summer and freeze-thaw cycles, shingles can degrade and lose their protective granules prematurely. While some granule loss is normal on new roofs, excessive loss is a sign of aging and leaves your roof vulnerable to UV damage and leaks. We recommend a professional inspection to assess the extent of the wear and discuss repair or replacement options to protect your home.

A leaking roof valley is a critical issue, especially in Bozeman with our heavy snowfall. Valleys channel a lot of water, so leaks here can cause major interior damage. Often, valley leaks can be repaired by resealing or replacing the flashing and valley metal. However, if the surrounding shingles are also compromised, a larger section or full replacement may be the most cost-effective, long-term solution. We'll provide an honest assessment and recommend the most targeted repair to stop the leak and prevent future problems.

For durability against our local conditions, we recommend impact-resistant asphalt shingles rated for high winds and hail, or metal roofing. Metal excels in shedding heavy snow and resisting granule loss entirely. For valleys, we use premium, wide flashing and proper ice and water shield underlayment—a must for our climate—to prevent leaks at these critical junctions. We'll help you choose a material and system that offers the best protection and value for your specific Bozeman home.
