Your roof may be out of sight, but it should never be out of mind, especially in Austin's climate, where heat, humidity, and storms can speed up wear and tear. For asphalt shingle roofs, dirt and grime don't just look bad; they can lead to serious damage if left untreated.
Here are five signs it's time to clean your roof before small problems turn into big ones.
1. Black Streaks or Dark Patches
If your roof looks like it has uneven dark streaks, chances are you're dealing with algae buildup. This is a common problem in Austin, especially in humid, shaded areas. Algae doesn't just affect appearance; it feeds on the limestone in shingles and can shorten your roof's lifespan.
Dark streaks also absorb more sunlight, making your home hotter and forcing your HVAC system to work harder. That means higher energy bills and more wear on your shingles.

2. Moss or Lichen Growth
Green clumps of moss or crusty patches of lichen are a major red flag. Moss traps moisture against the roof surface, which can lift shingles, cause rot, and lead to leaks over time. Lichen creates tiny root-like anchors that can damage the shingle surface.
If you spot either, it's a clear sign your roof needs attention—and quickly.
3. Granule Loss and Shingle Wear
Asphalt shingles have protective granules that help reflect sunlight and shield the material underneath. When those granules wear away—often due to dirt, mold, or age—your roof becomes more vulnerable to UV damage and water intrusion.
You might notice granules collecting in gutters or bald spots on the shingles themselves. While some granule loss is natural, large areas of thinning or shiny shingles are signs that cleaning or replacement may be needed.
4. Clogged or Overflowing Gutters
Gutters filled with debris, shingle granules, or roof runoff can signal a dirty or deteriorating roof. Overflowing gutters can also lead to water pooling at the roof edge, promoting algae, rot, and mold growth.
Regular gutter cleaning helps, but if the issue persists, your roof may need a more thorough cleaning to address the root cause.
5. Reduced Curb Appeal
A dirty, streaky, or moss-covered roof can instantly lower your home's visual appeal and resale value. Whether you're planning to sell or just want to protect your property value, a clean roof is one of the simplest upgrades you can make.
In Austin's competitive housing market, first impressions matter. A clean roof says a home is well cared for—and often reassures buyers, appraisers, and even insurance companies.
Don't Wait for Damage to Set In
If your roof shows any of these signs, it's time to take action. Cleaning your asphalt shingle roof doesn't just improve how your home looks, it protects one of your biggest investments.
