Professional Roof Cleaning in Tysons, Virginia
Those dark streaks running down your Tysons roofline aren't dirt — they're colonies of algae feeding on your shingles. Soft-wash roof cleaning removes them without a drop of damaging pressure. It's one of the most common calls we get from Tysons homeowners — and the fix is a soft-wash treatment that kills the growth at its root, with zero pressure on your shingles.
The Short Answer
Most Tysons roof cleanings start at $450, with the final price driven by roof size, pitch, and how established the algae or moss is. We soft-wash only — low pressure plus shingle-safe chemistry, the method asphalt shingle manufacturers recommend — so granules stay put and warranties stay intact. Because treatment kills growth at the root instead of rinsing the surface, results typically hold for 3–5 years. North-facing and tree-shaded slopes grow it back fastest, so we inspect every roofline before quoting — you know exactly what the treatment covers before we start. Every job starts with a free walkthrough and ends with a written, line-item quote in 24–48 hours.

Local Knowledge
What Roof Cleaning in Tysons Actually Involves
- The roofs we see most often in Tysons fall into two campsThe first is the shaded, wooded lot common in Pimmit Hills, Idylwood, and Stonewall Manor — homes built in the 1950s through the 1970s, ringed by mature trees that drop leaves, pollen, and constant shade onto north-facing slopes. Those slopes rarely see.
- Add in Tysons' seasonal tree debristhe oaks and poplars that make streets like those near Old Courthouse and Wolf Trap so desirable also shed heavily each fall — and gutters clog, valleys hold organic matter, and that trapped moisture accelerates both algae growth and shingle aging. A.

Roof Cleaning in Tysons — Common Questions
What is causing the black streaks on my roof in Tysons?
Those streaks are colonies of Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles. It spreads via airborne spores and thrives in the humid, tree-shaded conditions common across Tysons neighborhoods like Pimmit Hills and Idylwood. It's a biological growth issue, not surface dirt, so pressure washing alone won't solve it long term.
Is pressure washing safe for my roof?
No. High-pressure washing can strip the protective granules off asphalt shingles, force water under flashing and into the roof deck, and void many manufacturers' warranties outright. We use a low-pressure soft-wash method that applies a cleaning solution to kill algae, moss, and lichen at the root without damaging the shingle surface.
My roof is on a shaded, north-facing slope and has moss buildup. Can that be treated?
Yes. North-facing slopes in wooded Tysons neighborhoods stay damp longer and are the most common spot we find moss and lichen taking hold between shingle tabs. Our soft-wash treatment is formulated to break down and remove moss growth without lifting or damaging the shingles underneath.
Will roof cleaning damage my gutters?
Done correctly, no. Our process is engineered to be safe for gutters, downspouts, and the plantings below the roofline. We control runoff and rinse thoroughly so cleaning solution doesn't sit in the gutter system or damage landscaping at ground level. Our crews work Tysons regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of your roofline.
How often should a Tysons homeowner get their roof cleaned?
It depends on tree cover, roof age, and slope orientation. Heavily shaded properties in areas like Idylwood or Stonewall Manor with mature tree canopy may need attention every 2-3 years, while sun-exposed roofs in newer developments can often go longer. We assess your specific roof during inspection rather than applying a one-size schedule.
Do you clean older shingle roofs as well as newer architectural shingles?
Yes, but we treat them differently. Older roofs common in Pimmit Hills and Westwood Village require a more conservative approach given decades of granule wear, while newer architectural shingles in communities like Scotts Run can handle a more thorough treatment. We inspect roof age and material condition before determining our approach.
Is soft washing safe for asphalt shingles?
Yes — it is the method shingle manufacturers recommend. Low pressure and proper chemistry remove growth without stripping granules or voiding warranties, which is why we never put a pressure washer on any roof. Serving Tysons and all of Fairfax County. Our crews work Tysons regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of your roofline.
