The Ultimate Guide to Roof Soft Washing in Georgia: Why It Matters and How It Protects Your Home

August 26, 20256 min read

Georgia Roofs Take a Beating

From Cobb County to Cherokee County, Georgia homeowners know their roofs are under constant attack. Humidity, pollen, heavy rains, and relentless sun all contribute to a cocktail of roof-killing contaminants—especially Gloeocapsa Magma, the notorious black-streak algae.

If you’ve spotted dark streaks on your shingles, patches of moss, or even lichen growing on your roof, your home is telling you something: it’s time for a roof soft wash.

This guide breaks down everything you need to know about soft washing, including:

  • What roof soft washing is and how it works

  • Why it’s safer than traditional pressure washing

  • The top benefits of soft washing for Georgia homeowners

  • Signs your roof needs a soft wash

  • When to schedule it

  • How much it costs

  • And how to choose the right soft washing professional


What Is Roof Soft Washing?

Soft washing is a low-pressure cleaning method that uses specialized cleaning solutions to eliminate mold, algae, lichen, and moss from your roof without causing damage to shingles or tiles.

Unlike traditional pressure washing, which uses high PSI that can damage roofing materials, soft washing:

  • Uses low-pressure nozzles

  • Applies eco-friendly cleaning detergents

  • Kills contaminants at the root rather than just rinsing them off

  • Is gentle, safe, and effective

Think of it as a deep clean and disinfection for your roof, rather than a simple rinse.


Why Roofs in Georgia Need Soft Washing More Often

Georgia's warm, wet climate makes it a breeding ground for biological growth. Here's what homeowners are up against:

ContaminantProblemGloeocapsa Magma (black algae)Creates black streaks, breaks down shinglesMossHolds moisture, lifts shingles, causes rotLichenDigs into shingles, reduces lifespanPollenAccumulates quickly, feeds mold growthRed ClayStains shingles and attracts grime

If left untreated, these invaders can:

  • Reduce your roof’s energy efficiency

  • Shorten its lifespan by up to 10 years

  • Lead to wood rot, leaks, and mold inside the attic

  • Decrease your home’s curb appeal and value


How Soft Washing Works: Step-by-Step

  1. Inspection
    A professional examines the roof, noting problem areas and ensuring the surface is appropriate for soft washing.

  2. Application of Cleaning Solution
    A specially formulated mixture of water, sodium hypochlorite, and surfactants is sprayed on using low pressure.

  3. Dwell Time
    The solution is left to sit (usually 10–20 minutes), allowing it to kill bacteria, mold, algae, and other contaminants.

  4. Gentle Rinse (if needed)
    In some cases, a light rinse is used. In others, rain naturally washes away dead organic matter over time.

  5. Post-Treatment Evaluation
    Final check to ensure all areas are treated and safe.

For roofs, pressure washing is not recommended—it can void warranties, blow off granules, and even break shingles. Soft washing is the industry standard.


Top 7 Benefits of Roof Soft Washing for Georgia Homes

1. Extends Roof Life

Soft washing removes contaminants that degrade your shingles and trap moisture.

2. Prevents Costly Repairs

Avoid rot, leaks, and structural damage by eliminating harmful growth early.

3. Boosts Curb Appeal

A clean roof drastically improves the look of your home—great for selling or appraisals.

4. Improves Energy Efficiency

Dark algae absorbs heat. Removing it helps your home stay cooler.

5. Kills Organic Growth at the Root

Pressure washing only rinses the surface. Soft washing kills algae, moss, and mold completely.

6. Safe for All Roofing Materials

Asphalt, tile, metal—soft washing works on them all without causing damage.

7. Complies with Manufacturer Warranties

Most roofing manufacturers specifically recommend soft washing to keep warranties valid.


Signs Your Roof Needs a Soft Wash

Not sure if it’s time to clean your roof? Look for these common signs:

  • Black streaks or staining

  • Patches of green moss or lichen

  • Roof looks older than it is

  • Increased indoor humidity or attic smell

  • Water stains on ceiling (can indicate roof leaks)

  • You can’t remember the last time it was cleaned (more than 2 years)


How Often Should You Soft Wash Your Roof in Georgia?

In Georgia’s climate, the sweet spot is every 2–3 years—but it can depend on several factors:

  • Shade: Heavily shaded roofs need cleaning more often

  • Surrounding trees: More trees = more debris and organic growth

  • Roof color: Dark roofs show staining sooner

  • Humidity levels: High humidity = faster algae growth

Some homeowners opt for annual inspections to stay ahead of any buildup.


How Much Does Roof Soft Washing Cost in Georgia?

Here’s a general estimate:

Roof SizeEstimated Price RangeSmall (under 1,500 sq ft)$250–$400Medium (1,500–2,500 sq ft)$400–$600Large (2,500–4,000 sq ft)$600–$900Extra Large/Complex Roof$900+

Factors that affect cost:

  • Roof pitch and accessibility

  • Severity of algae/moss buildup

  • Multi-story homes

  • Additional treatments or sealing

Pro tip: Ask if the company includes a warranty or satisfaction guarantee on their soft wash services.


DIY Soft Washing: Is It Safe?

Short answer: Not recommended.

Even though soft washing uses low pressure, the chemical application still requires:

  • Ladder safety knowledge

  • Roof safety gear

  • Professional-grade detergents (not store-bought bleach)

  • Understanding of roof types and runoff precautions

  • Precise mix ratios to avoid killing plants or damaging surfaces

Hiring a licensed and insured professional ensures safety and results.


Choosing the Right Roof Soft Washing Company in Georgia

Before you hire, ask these important questions:

  • Are you licensed and insured?

  • Do you specialize in roof soft washing (not just general pressure washing)?

  • Do you use biodegradable, plant-safe cleaners?

  • Can I see before-and-after photos of your work?

  • Do you offer a guarantee or follow-up service?

A reputable company will gladly answer these and show you proof of success.


Seasonal Timing: When Is the Best Time to Soft Wash a Roof in Georgia?

The ideal time to soft wash your roof is:

  • Late spring to early summer (after pollen has settled)

  • Early fall (before winter moisture sets in)

Avoid freezing months and always check the forecast—soft washing is best done during dry, sunny periods to allow solutions to work effectively and rinse naturally.


What to Expect After a Soft Wash

After your soft wash is complete:

  • Your roof will appear cleaner almost immediately

  • Some deeper stains or lichen may lighten over several days

  • Rain will help rinse away remaining residue

  • You’ll notice cooler attic temps and improved curb appeal

  • Surfaces will be protected for up to 2–3 years (longer with proper maintenance)


Final Thoughts: Protect Your Roof, Protect Your Home

Your roof is your home’s first line of defense—and in Georgia, it needs all the help it can get. Soft washing is a safe, effective, and affordable way to:

  • Extend roof lifespan

  • Avoid costly repairs

  • Improve your home’s appearance

  • Preserve resale value

  • Protect your family’s health by eliminating mold and algae
