Professional roof cleaning that removes algae, moss, and stains without damaging your shingles or voiding warranties.

Those black streaks aren’t just ugly—they’re costing you money. Algae-covered roofs absorb more heat, driving up your cooling costs and shortening your roof’s lifespan. When fungus and algae eat away at your shingle base, they loosen the protective granules that shield your home from the elements.
A clean roof reflects heat instead of absorbing it. Your air conditioning won’t work as hard. Your shingles last longer. Your home looks better from the street.
The difference shows up in your energy bills, your property value, and your peace of mind knowing your roof is actually protecting your home instead of deteriorating under a blanket of growth.
Blue Ridge Exterior Cleaning has served Central Virginia for over 15 Years, built on old-fashioned values and a commitment to quality. We specialize in manufacturer-approved cleaning methods that major shingle companies like GAF and CertainTEED actually endorse—not the harsh pressure washing that voids warranties.
Our team holds certifications from industry leaders including the National Soft Wash Alliance and Spray Wash Pro. You’ll always get a real person on the phone, clear communication throughout the process, and results that speak for themselves.
In Sherando’s humid climate, where moss and algae thrive in the shade of the Blue Ridge Mountains, we’ve seen every type of roof challenge. From historic properties to modern homes, we handle each project with the care it deserves.
The process starts with a thorough inspection to identify the type of growth on your roof—algae, moss, lichen, or mold all require different approaches. We never use high pressure that can strip away protective granules or void your shingle warranty.
Instead, we apply specialized cleaning solutions that work through chemistry. The stains literally disappear before your eyes as the treatment breaks down algae and organic growth at the source. For moss and lichen, there’s a transition period where the growth dies and naturally falls away from your shingles.
We protect your landscaping throughout the process and clean up completely when finished. The entire job typically takes a few hours, but the results last for years. You get a roof that looks almost new again without any risk of damage.

Sherando’s location in the Shenandoah Valley creates perfect conditions for roof growth. The combination of humidity, seasonal rainfall, and tree cover means algae can appear on shaded roofs in as little as three years. North-facing roof sections are especially vulnerable since they get less direct sunlight to naturally inhibit growth.
Our service includes complete removal of black algae streaks, green moss buildup, and lichen colonies that dig into your shingles. We treat the entire roof surface, not just the visible problem areas, because spores spread and what looks clean today might show stains next season.
For metal roofs common in Sherando’s rural areas, we use specialized techniques that won’t scratch or damage the finish. Standing seam, corrugated, and painted metal all require different approaches to remove organic growth while preserving the protective coating that prevents rust and corrosion.
