In our climate, common signs include interior water stains or leaks, especially after heavy rain, curling or buckling shingles, and a spongy feel when walking on the roof. The underlayment is a critical moisture barrier, and our intense sun and humidity can cause it to deteriorate. We recommend a professional inspection if you notice any of these issues.

Granule loss is a significant issue here due to prolonged UV exposure and thermal cycling. While some loss over time is normal, excessive granule loss in your gutters or downspouts exposes the asphalt layer, leading to faster aging and reduced fire resistance. It's a clear sign your shingles are deteriorating and may need repair or replacement to prevent leaks.

For our local conditions, we prioritize solutions that combat UV damage and moisture. This includes using high-quality, reflective asphalt shingles rated for our climate, ensuring proper attic ventilation to reduce heat buildup, and installing robust, code-compliant underlayment systems. Our repairs and replacements are designed to withstand the South Texas sun, wind, and occasional severe weather.
