How Often Should You Pressure Wash Your Roof in Georgia?

September 2, 2025

If you’ve noticed black streaks or green patches on your roof, you’re not alone. Georgia’s hot, humid climate creates the perfect environment for algae, moss, and mildew to grow. These stains aren’t just ugly — they can shorten the lifespan of your shingles.

So how often should you schedule roof cleaning? Let’s break it down.

The Impact of Georgia’s Climate on Roofs

In Middle Georgia, high humidity and frequent rain create year-round moisture on roofs. Add in pollen, falling leaves, and warm temperatures, and it’s the perfect recipe for algae and mold growth.

Unlike dirt, these organisms actually eat away at shingles, leading to early deterioration if not treated.


Recommended Roof Cleaning Frequency

For most Georgia homes, the rule of thumb is:


  • Every 1–2 years for standard shingle roofs
  • Annually if your home is shaded or surrounded by trees
  • As needed if you see visible black streaks, green patches, or moss


Regular roof cleaning prevents buildup and protects your investment.


Why Soft Washing Is Best for Roofs

Pressure washing may be powerful, but it’s too harsh for roofing materials. Instead, professional roof cleaning uses soft washing — a low-pressure method combined with safe cleaning solutions.


This approach:


  • Kills algae, mold, and bacteria at the root
  • Removes stains without damaging shingles
  • Extends roof lifespan and improves curb appeal


Signs It’s Time to Clean Your Roof

  • Black streaks running down shingles
  • Green moss patches or lichen growth
  • Roof looks older or “dingy” compared to neighbors
  • Gutters clogging faster than usual


If you see any of these signs, it’s time to schedule a cleaning before small issues become big repairs.

Final Thoughts
