Most commercial roofs in San Antonio do not fail from age. They fail from heat. Dark membranes hit 150 to 180 degrees on a summer afternoon, and that daily expansion cycle is what opens seams, hardens sealant, and eventually puts water on your ceiling tiles. Here is how surface temperature drives leak history, what an infrared scan reveals about it, and where a reflective coating system helps and where it does not.

Flat roofs in Central Texas rarely fail all at once. They open up slowly at seams, curbs, and flashings until trapped moisture finally shows up on a ceiling tile. Here is where low-slope roofs actually leak, why Texas heat and heavy rain accelerate the process, and how liquid-applied coating systems seal an existing roof and add years of service life without a tear-off.
