That black grit is likely granules from your asphalt shingles. In our intense South Texas sun, shingles can lose these protective granules prematurely, exposing the asphalt to UV damage and shortening the roof's lifespan. It's a sign your shingles are aging. We recommend a professional inspection to assess the extent of the granule loss and determine if targeted repairs or a replacement are needed to prevent leaks.

San Antonio's humidity and temperature swings accelerate corrosion on standard galvanized steel flashing. At Debakey Roofing, we prevent this by using superior, corrosion-resistant materials like aluminum or coated metals for critical areas like chimneys, vents, and valleys. Our expert installation ensures a watertight seal, and during inspections, we specifically check flashing for early signs of wear, addressing minor issues before they lead to major leaks inside your home.

It depends on the extent and location of the damage. For isolated areas where granule loss has caused a leak or where flashing has corroded, we can often perform a precise repair that matches your existing roof. However, if the damage is widespread or the surrounding shingles are also aged and brittle, a partial repair may not be cost-effective or durable. We'll give you an honest, neighborly assessment to recommend the most reliable and economical solution for your specific situation.
