What You Need to Know About Roof Cleaning Services in Buffalo, NY

Buffalo homeowners know just how intense our weather can be—from lake-effect snow and ice in winter to humid summers and plenty of rain in between. All that moisture creates the perfect environment for moss, algae, and debris to collect on your roof, leading to long-term damage if left untreated.

At Wm. C. Rott & Son, we understand how critical regular roof cleaning is to the health and longevity of your home. As Buffalo’s most trusted roofing experts for over 100 years, we’re here to help you protect your investment and keep your roof in top condition.

The Impact of Buffalo Weather on Your Roof

Buffalo’s seasonal extremes are tough on roofing systems. Snow and ice pile up in the winter, creating opportunities for moisture to seep beneath shingles. In spring and summer, warm temperatures combined with high humidity promote the growth of algae, moss, and lichen.

Add in shaded areas from large trees and fallen leaves in the fall, and you’ve got a recipe for roof deterioration—unless it’s cleaned and maintained properly. Even newer roofs can suffer premature aging without regular cleaning.

What Is Roof Cleaning and Why Is It Important?

Roof cleaning in Buffalo involves the professional removal of organic growth, dirt, and debris from your roof’s surface. Unlike a basic rinse with a hose, professional roof cleaning tackles the root of the problem—often algae and moss that cling tightly to your shingles and eat away at the protective layers.

Regular roof cleaning offers key benefits:

• Extends roof lifespan by preventing material breakdown
• Improves curb appeal by removing dark streaks and stains
• Prevents costly repairs by catching problems early
• Increases energy efficiency by reducing heat-absorbing buildup

Common Roof Contaminants in Buffalo

There are a few culprits we commonly see affecting Buffalo roofs:

• Moss: Grows in damp, shaded areas and lifts shingles as it expands, allowing water to seep in.
• Algae (Gloeocapsa Magma): Appears as dark streaks and feeds on the limestone filler in shingles.
• Lichen: A combination of fungus and algae that’s tough to remove and can permanently damage roofing materials.
• Organic Debris: Leaves, twigs, and pollen clog up drainage paths and trap moisture, especially near gutters and valleys.

Soft Wash Roof Cleaning: The Safe Solution

Not all roof cleaning methods are created equal. High-pressure power washing can damage shingles, void manufacturer warranties, and lead to even more problems.

That’s why Wm. C. Rott & Son uses soft wash roof cleaning—a low-pressure method that safely removes stains, moss, and algae using eco-friendly, biodegradable cleaning agents. It’s gentle on your roof but tough on grime.

Our process includes:

• A full roof inspection
• Application of a professional-grade soft wash solution
• Controlled rinse to remove contaminants
• Clean-up and post-inspection to ensure quality results

The result? A Buffalo roof that looks better, lasts longer, and protects your home more effectively.

When Should Buffalo Homeowners Schedule Roof Cleaning?

We recommend cleaning your roof every 2–3 years, but the frequency can vary depending on your home’s location, shading, and surrounding foliage. The best times to schedule roof cleaning in Buffalo are:

• Spring: After snowmelt, to prevent moss and algae from setting in.
• Fall: After leaves drop, to clear organic debris before winter.

You should also call for service if you notice:

• Black or dark green streaks on your shingles
• Clumps of moss or growth
• Overflowing gutters or downspouts
• Shingles lifting or curling
