The claim that a cool roof cuts cooling costs by 30 percent gets repeated often, but the real number depends far more on your building than on the coating. This guide breaks down how reflective coatings lower heat gain on San Antonio commercial roofs, what savings are realistic, and which factors decide whether your property is a strong candidate.

A dark low-slope roof in San Antonio can hit 190 degrees on an August afternoon, and your cooling system pays for every bit of it. Here's what reflective roof coatings actually save, how solar reflectance and thermal emittance work, and when recoating makes more sense than living with a hot roof.

Solar shingles promise energy savings, but they only make sense with a full roof replacement. Reflective, energy-efficient roof coatings often solve San Antonio's heat and energy-bill problem faster, without tearing off the existing roof.

The air conditioner runs from sunrise past sunset, the electric bill creeps higher every cycle, and the house never quite feels as cool as the thermostat claims it should. Most people respond by servicing the AC or adding attic insulation, and both are worthwhile steps. But the roof itself, the single largest surface exposed to direct sun for hours every day, rarely gets a second look until something starts leaking. That's the part most people miss.
