Yes, granule loss is a common sign of aging shingles, often accelerated by New York's seasonal temperature swings and storms. Those granules protect the asphalt from UV rays. Without them, your roof becomes vulnerable to faster deterioration and leaks. GJM Construction can inspect the extent of the loss, determine if localized repair or a full replacement is needed, and recommend materials suited for our local climate to ensure long-term protection.

Our roofing specialists at GJM Construction carefully inspect the valley flashing and underlying structure for damage or wear. We then repair or replace the flashing with proper sealing techniques, ensuring water is effectively diverted away from your home to prevent interior water damage.
