Safe, Effective Roof Washing
Serving Knoxville & Surrounding Areas
Why Roof Washing Matters
Stop Damage, Restore Curb Appeal
Dark streaks and roof staining are usually caused by algae (Gloeocapsa magma), along with moss and lichen that trap moisture. Left untreated, these growths accelerate shingle granule loss, weaken protective coatings, and can lead to premature aging, leaks, and wood rot. A clean roof also reflects heat more effectively, helping your home stay cooler and potentially reducing energy costs.
Brown’s Exterior Services uses manufacturer-recommended soft washing to safely clean and sanitize roofing materials without high pressure. Our detergents break down organic contamination at the root, restoring color and curb appeal while helping preserve shingle life and protect warranty coverage. The result is a healthier roof, longer service life, and a better-looking home.
Low-Pressure Soft Washing, Done Right
We begin with a detailed inspection to identify your roofing material, stain sources, and any vulnerable areas such as loose flashing or delicate features. Next, we create a tailored cleaning plan, select the correct soft-wash blend, and establish safety measures for crew and property.
On cleaning day, we protect landscaping, manage runoff, and prepare gutters. Our technicians apply a precise, low-pressure detergent treatment that dissolves algae, moss, and lichen, followed by a gentle rinse as needed. We confirm results, tidy the site, and provide aftercare tips to help you keep your roof cleaner, longer. Our team is trained, insured, and committed to safe, consistent results.
Benefits, Roof Types, and Timing
Professional roof washing extends roof life, improves drainage, and restores true shingle color for instant curb appeal and property value. By removing organisms that feed on roofing materials, soft washing helps preserve protective granules and coatings. The service is efficient, uses water wisely, and is designed to be gentle on your home’s exterior.
We clean asphalt and architectural shingles, metal roofing, clay and concrete tile, slate, and composite products. Cedar shake and other specialty materials receive adjusted chemistry and extra care. We never rely on damaging high pressure for roof surfaces; instead, we use purpose-built soft-wash equipment and techniques aligned with manufacturer guidance.
Schedule service when you see black streaks, moss, or lichen, after storm debris or heavy pollen seasons, or as part of routine care every 1–3 years depending on shade and tree coverage. We can set up maintenance reminders, document results with photos, and provide recommendations to help your roof stay cleaner between visits.
