How Often Should You Clean Your Roof? A Guide for Buffalo, NY Homeowners

Your roof is one of your home’s most important protective barriers—but it’s often one of the most neglected. In a climate like Buffalo’s, where snow, moisture, and tree debris are part of life, regular roof cleaning is essential. But how often should you actually clean your roof?

At Wm. C. Rott & Son, we’ve helped Western New York homeowners care for their roofs for over a century. Here’s everything you need to know about roof cleaning frequency—and how to protect your investment year-round.

Why Roof Cleaning Matters in Buffalo

Buffalo’s long winters and humid summers can take a serious toll on roofing materials. Snow, ice dams, and shaded areas allow moisture to linger, creating a perfect breeding ground for moss, algae, and mold. Over time, this buildup can damage shingles, trap heat, and shorten the lifespan of your roof.

Regular roof cleaning doesn’t just improve curb appeal—it helps prevent expensive repairs down the road. And no one knows Buffalo roofs better than Wm. C. Rott & Son, your local roofing experts since 1909.

How Often Should You Clean Your Roof?

Most homeowners should clean their roof at least once per year. However, in Buffalo’s climate, cleaning twice per year—once in the spring and again in the fall—is ideal for optimal protection.

You may need more frequent cleaning if you notice:

• Black streaks or staining (typically algae)
• Moss or lichen growing on shingles
• Clogged gutters from tree debris
• Dull or patchy shingles
• Increased indoor humidity or roof leaks

The more shade or tree coverage you have, the more frequently you may need to clean your roof.

What Impacts Roof Cleaning Frequency?

Tree Coverage

Buffalo’s leafy neighborhoods are beautiful—but shade from overhanging trees keeps moisture on your roof longer. Leaves, twigs, and pine needles can clog gutters and trap water on your shingles.

Roof Age and Material

Older roofs are more delicate and may need gentler, more frequent cleanings. Asphalt shingles, the most common type in Buffalo, are especially prone to moss and algae if not properly maintained.

Weather Patterns

Our local freeze-thaw cycles can worsen moss growth and structural damage if not addressed promptly. After a harsh winter, your roof may need a cleaning and inspection to remove debris and identify wear.
