Lumor Roofing | Qualified Roof Repair in San Antonio, TX

In San Antonio, roof decking rot is often caused by a combination of high humidity, trapped moisture from improper attic ventilation, and minor, undetected leaks. The plywood or OSB sheathing beneath your shingles can weaken and decay. Fixing it requires a professional to safely remove the affected shingles, replace the rotted decking with new, treated wood, ensure proper ventilation is restored, and re-install your roofing materials. Ignoring deck rot can lead to structural issues and mold growth inside your home.

Premature granule loss in San Antonio is frequently a result of our intense UV exposure and thermal cycling, which can break down the asphalt in shingles. While some granule loss is normal over time, excessive loss, especially in younger roofs, exposes the shingle mat to the sun, accelerating aging and reducing protection. It's a serious sign of deterioration. Our inspection can determine if the issue is isolated or widespread, and we'll recommend targeted repairs or a replacement with more UV-resistant shingles designed for our climate.

For longevity against San Antonio's sun and storms, we recommend impact-resistant architectural shingles with reflective coatings to combat UV damage and reduce attic heat. For decking, using moisture-resistant OSB or plywood and ensuring impeccable attic ventilation are key. Metal roofing is also an excellent, durable option that sheds heat and resists rot. During a consultation, we assess your home's specific exposure, slope, and ventilation to recommend the most resilient material system for your budget and style.
