Your roof does more than just protect your home; it also plays a major role in your property’s curb appeal and overall value. Yet, many Louisiana homeowners overlook one crucial part of roof maintenance: roof cleaning. Between the region’s humid climate and frequent rain, it’s common to see black streaks, moss, and algae buildup.
In this guide, we’ll cover why professional roof cleaning matters, how it’s done safely, what it costs, and how it helps extend your roof’s lifespan.
Why Roof Cleaning Matters for Louisiana Homeowners
Louisiana’s humid subtropical climate makes it the perfect breeding ground for algae, mold, mildew, and moss. These growths don’t just affect appearance; they can also weaken your roof’s materials over time.
Regular roof cleaning prevents:
- Premature roof damage caused by moss and algae eating into shingles.
- Water pooling and leaks due to clogged granules.
- Reduced energy efficiency from dark streaks absorbing more heat.
- Decreased home value and curb appeal.
A clean roof not only looks better but also helps your shingles last longer, saving you money on costly repairs or replacements.
Common Causes of Roof Stains, Moss, and Algae
Those dark streaks on your roof are typically caused by Gloeocapsa magma, a type of blue-green algae that thrives in humid climates like Louisiana. Over time, it spreads and creates dark streaks that trap heat and moisture.
Other culprits include:
- Moss: Grows in shaded, damp areas and lifts shingles, leading to leaks.
- Lichen: A mix of fungus and algae that clings stubbornly to surfaces.
- Tree debris: Leaves, twigs, and pine needles trap moisture and encourage growth.

Soft Wash vs. Pressure Wash: What’s the Difference?
When it comes to professional roof cleaning services, there are two main methods:
Soft Washing
- Uses low-pressure water combined with cleaning solutions.
- Gently removes dirt, moss, and algae without damaging shingles.
- Ideal for asphalt, tile, and metal roofs.
Pressure Washing
- Uses high-pressure water to blast away debris.
- Effective for certain hard surfaces, but can damage shingles if not done carefully.
For most Louisiana homes, soft washing is the recommended and safest approach.
