Gentle but effective cleaning that removes algae, moss, and black streaks — extending your roof's life and restoring your home's curb appeal without damaging a single shingle.
Those dark streaks running down your roof are not just dirt — they are caused by Gloeocapsa magma, a type of blue-green algae that feeds on the limestone filler in asphalt shingles. Left untreated, this algae spreads across your roof, trapping moisture and accelerating the breakdown of roofing materials.
Moss and lichen are even more destructive. They grow between and underneath shingles, lifting them away from the roof deck and creating pathways for water to seep in. Over time, this leads to leaks, rot, and premature roof failure — problems that cost thousands of dollars to fix.
Professional roof soft washing eliminates these biological threats and restores your roof's appearance. It is one of the smartest investments you can make in your home's longevity and curb appeal.
Regular soft washing removes the organisms that break down roofing materials, helping your roof last its full expected lifespan — or longer.
A clean roof dramatically changes the look of your entire home. Black streaks and green patches make even well-maintained homes look neglected.
A $300-$600 soft wash is far cheaper than the $8,000-$15,000 cost of a premature roof replacement caused by biological damage.
Whether you are selling or staying, a clean roof signals that a home is well cared for. Appraisers and buyers notice.
We assess your roof's condition, identify the type and extent of biological growth, and check for any existing damage before we begin.
We protect your landscaping, siding, and outdoor furniture. Gutters and downspouts are prepped to handle runoff safely.
Using low-pressure equipment, we apply an eco-friendly cleaning solution that kills algae, moss, lichen, and mildew at the root — without damaging your roofing materials.
We rinse the roof at low pressure to remove the cleaning solution and loosened debris. No high-pressure blasting that could damage shingles or tiles.
We inspect the completed work, clean up the surrounding area, and walk you through the results so you can see the difference.
High-pressure washing might seem like the fastest way to clean a roof, but it is one of the worst things you can do to your roofing materials.
