ROOF CLEANING/MOSS REMOVAL

Moss does far more than affect curb appeal. Once established, it acts like a sponge, retaining moisture against your shingles for long periods of time. This constant moisture leads to several major issues:

• Shingle deterioration: Moss grows underneath and between shingles, lifting them and allowing water to penetrate the roof system.

• Granule loss: Asphalt shingles rely on protective granules to shield against UV rays. Moss loosens and strips these granules, accelerating aging.

• Freeze-thaw damage: Trapped moisture freezes and expands during Alaska’s cold months, cracking shingles and breaking down their integrity.

• Shortened roof lifespan: Over time, moss can reduce the life of a roof by many years, leading to premature replacement.

Ignoring moss growth can turn a minor maintenance issue into a major roofing expense.

Soft washing is the industry-recommended method for roof cleaning and moss removal. Instead of relying on pressure, soft washing uses low-pressure application combined with specialized cleaning solutions designed to safely break down and eliminate moss, algae, and organic growth at the root.

How Soft Washing Works:

• We apply a low-pressure solution similar to garden hose pressure

• The solution penetrates moss and organic growth, killing it at the root

• Moss loosens naturally without damaging shingles

• The roof is left clean and protected without force

Because this method does not rely on pressure, it preserves shingle integrity, prevents water intrusion, and maintains manufacturer warranties.

Why Soft Washing Is Ideal for Alaska Roofs

Alaska roofs face unique challenges, including prolonged moisture, snow buildup, and extreme freeze-thaw cycles. Soft washing is ideal because it:

• Prevents shingle lifting and cracking

• Eliminates moss spores to slow regrowth

• Reduces moisture retention on the roof surface

• Helps roofs dry faster after rain and snow melt

• Extends the overall lifespan of your roof

Many roofs we service see continued improvement after treatment as remaining moss dries up and naturally detaches over time.

Long-Term Protection, Not Just a Quick Fix

Our roof cleaning process doesn’t just remove visible moss — it targets the underlying growth that causes regrowth. This means fewer cleanings over time and better long-term protection for your home.

Regular roof maintenance through professional soft washing can:

• Prevent costly repairs

• Maintain curb appeal

• Protect your investment

• Increase resale value

After a professional softwash, any remaining moss on the roof will turn white, which is a clear sign that it is dead. The softwashing solution penetrates deep into the moss and down to its root system, killing it at the source and allowing the roots to detach from the shingles without causing damage. Because this is a low-pressure, chemical treatment—not forceful washing—the dead moss is left in place to naturally release over time. With normal wind and rain, the dead growth gradually falls off. This natural process typically takes 6–8 months for all remaining debris to fully shed. Our soft wash service also includes a 2-year MOSS FREE warranty—if you see any green moss or regrowth during that time, we’ll return and retreat the affected areas free of charge. (See photo Below)
