Roof Cleaning in Arlington, Virginia
Roof Cleaning in Arlington isn't the same job it is one county over. Here, most homes are 1930s–50s brick colonials and Cape Cods, so surfaces and structures are older than almost anywhere else we work. Also worth knowing: lots are small — often 5,000–6,000 sq ft — with strict lot-coverage and setback rules that shape what can be built. And stream-adjacent properties fall under Resource Protection Area rules that affect grading and runoff.
The Short Answer
Most Arlington 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. Every job starts with a free walkthrough and ends with a written, line-item quote in 24–48 hours.

Roof Cleaning in Arlington — Common Questions
How much does roof cleaning cost in Arlington?
Professional roof cleaning in Arlington typically ranges from 0 to 0, depending on roof size, pitch, and material. Lawn Theory provides free estimates for all Arlington properties. Call (703) 650-5655 to schedule. Our crews work Arlington regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
What causes black streaks on roofs in Arlington?
Black streaks are caused by Gloeocapsa magma, a blue-green algae that feeds on limestone in asphalt shingles. Arlington's humid climate creates ideal growth conditions. Beyond being unsightly, this algae accelerates shingle deterioration and can reduce roof lifespan by up to 10 years if left untreated.
Will pressure washing damage my roof shingles?
High-pressure washing absolutely can damage shingles \— stripping protective granules, cracking tiles, and voiding warranties. That's why Lawn Theory exclusively uses low-pressure soft washing for all roof cleaning in Arlington. Our method is recommended by manufacturers including GAF, Owens Corning, and CertainTeed. Our crews work Arlington regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
How often should I have my roof cleaned in Arlington?
In Arlington's climate, we recommend professional roof cleaning every 2-3 years. Arlington's older homes often have complex roof lines with dormers, valleys, and varying pitches that create areas where debris and moisture collect, promoting algae and moss. Homes with heavy tree coverage or north-facing sections may benefit from more frequent cleaning.
Will roof cleaning void my warranty?
Soft washing will NOT void your roof warranty \— in fact, most manufacturers recommend it. However, high-pressure washing CAN void warranties. Lawn Theory only uses manufacturer-approved soft-wash methods specifically to protect both your roof and your warranty. Our crews work Arlington regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Can you clean slate, tile, and metal roofs in Arlington?
Yes. Lawn Theory's technicians are trained to safely clean all roof types found in Arlington: asphalt shingles, architectural shingles, cedar shake, slate, concrete tile, clay tile, standing seam metal, and synthetic roofing materials. Each material requires a different approach, and we adjust our methods accordingly.
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 Arlington and all of Northern Virginia. Our crews work Arlington regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
