Granule loss is often accelerated by our local temperature swings and weather exposure. The granules protect the asphalt shingle from UV rays. When they wear off, the shingle becomes brittle and loses its waterproofing ability, leading to faster deterioration and potential leaks. A professional inspection can determine if it's normal wear or a sign of a more serious issue.

Flashing separation around chimneys, vents, and valleys is a common leak source here. We inspect the existing flashing for corrosion or improper sealing, remove it carefully, and install new, high-quality flashing integrated with a proper underlayment system. This creates a watertight seal that withstands local wind and rain, preventing costly water intrusion into your home.

After major storms or seasonal changes, check your gutters for an excess of shingle granules (it looks like coarse black sand) and visually inspect flashings for any gaps or lifted sections. Inside, look for water stains on ceilings or in the attic. These are signs it's time for a professional evaluation to address small problems before they become major repairs.
