Moss and Algae Cleaning

Professional removal of moss, algae, and organic growth that damages shingles and shortens roof life. Safe, thorough cleaning that restores your roof's appearance and function.

Protect Your Roof from Organic Growth

Moss and algae aren't just cosmetic problems. In New Jersey's humid climate, these organisms trap moisture against your shingles, accelerating deterioration and lifting edges. Left unchecked, moss roots work under shingles, compromising your roof's waterproof barrier and leading to leaks.

We've cleaned hundreds of roofs across NJ, and the difference is immediate—not just in curb appeal, but in the health of the roof itself.

Our Cleaning Process

We don't pressure-wash. High-pressure water forces moisture under shingles and strips protective granules. Instead, we use low-pressure application of roof-safe solutions that kill growth at the root, followed by gentle rinsing. The treatment continues working for weeks, and dead growth naturally weathers away.

What we remove:

  • Black algae streaks (gloeocapsa magma)
  • Moss colonies and root systems
  • Lichen growth
  • Organic staining

Why Growth Happens

New Jersey's combination of shade, humidity, and seasonal rain creates ideal conditions. North-facing slopes and tree-shaded sections are especially vulnerable. Algae spores travel on the wind; moss spores hitch rides on birds and squirrels. Once established, they spread quickly.

Regular cleaning every few years keeps growth from taking hold and extends the life of your roof by years—sometimes a decade or more.

Safe for Your Roof and Landscaping

Our solutions are formulated for asphalt shingles, cedar shake, and tile. We protect your gutters, landscaping, and siding throughout the process. No damage to plants, no streaking on your home's exterior.


When to Schedule Cleaning

If you see dark streaks, green patches, or spongy growth, it's time. We recommend cleaning before growth becomes thick enough to lift shingles. Spring and fall are ideal seasons—mild temperatures help treatments work effectively without stressing your roof.

We'll inspect while we're up there and let you know if we spot any underlying issues. Sometimes what looks like a cleaning job reveals a repair need, and we'd rather catch it early.

How it works


Inspection and Assessment

We examine the extent of growth, identify problem areas, and check for any underlying damage that needs attention before or after cleaning.

Preparation and Protection

Gutters, landscaping, and siding are covered and protected. Downspouts are managed to control runoff safely.

Application and Treatment

Roof-safe cleaning solution is applied at low pressure to kill moss, algae, and lichen at the root without damaging shingles.

Rinse and Final Inspection

Gentle rinsing removes loose growth. We inspect the results and advise on any follow-up or preventive measures.

Common questions


Will cleaning damage my shingles?+

Not when done correctly. We use low-pressure methods specifically designed for roofing materials. Pressure washing, which many homeowners try themselves, is what causes damage—we never use high pressure.

How long does the cleaning last?+

Typically three to five years, depending on shade and exposure. Roofs with heavy tree cover may need more frequent treatment. We can also apply preventive treatments to slow regrowth.

Can I just let the moss stay if it's not leaking?+

Moss holds moisture and its roots physically lift shingles, creating pathways for water. By the time you see a leak, there's often hidden damage underneath. Cleaning now prevents expensive repairs later.
