Most Houston roofs are designed to last 20–30 years. But algae, moss, and debris can cut that lifespan in half if left unchecked. Regular roof cleaning is one of the smartest investments you can make in your home.
How Algae Destroys Shingles
Gloeocapsa magma algae feeds on the limestone in your shingles, causing granule loss. Those granules are your roof's sunscreen — without them, UV exposure degrades the asphalt layer underneath, leading to cracking, curling, and leaks.
The Heat Factor
Dark algae stains absorb more heat, raising attic temperatures and putting extra strain on your HVAC system. A clean roof can reduce cooling costs by 10–15% in Houston's summer heat.
How Often Should You Clean?
We recommend roof cleaning every 2–3 years in Houston. Heavily shaded roofs or those near large trees may need annual cleaning.
