Home & Commercial Roof Cleaning Knoxville, TN Soft Wash Moss & Algae Removal
Knox Exterior Care Co.
Safe, Low‑Pressure Roof Cleaning For Home & Commercial In Knoxville.
A streaky, moss‑covered roof drags down your property’s curb appeal — and can quietly shorten the life of your shingles or panels. Algae, moss, lichen, and built‑up debris trap moisture, loosen granules, and accelerate wear, especially in shaded East Tennessee neighborhoods and high‑tree‑cover commercial sites. Left alone, what starts as “just cosmetic” can turn into premature roof replacement and costly repairs on both homes and commercial buildings.
Knox Exterior Care Co. provides professional soft wash roof cleaning for residential and commercial properties throughout Knoxville and the surrounding areas. We use low‑pressure soft washing — not harsh, high‑pressure blasting — to safely remove organic growth, staining, and debris from your roof so it looks fresh again while protecting your shingles, flashing, gutters, and surrounding landscaping.
If you’ve been searching for roof cleaning near me, roof soft washing Knoxville TN, or moss removal for shingle or metal roofs near Knoxville — you’re in the right place.

Roof cleaning is priced based on your roof’s total square footage, roof type (asphalt shingle, metal, tile), pitch and accessibility, and how much moss, algae, or staining is present.
Heavily shaded homes, churches, and commercial roofs with significant moss and lichen growth may require a more intensive treatment and will be scoped accordingly.
We’ll walk the property, inspect your roof’s condition, and provide a clear written quote before any work begins — no surprises, no pushy upsells at the door.

Roof Cleaning FAQ’s
We hear these questions from Knoxville homeowners, business owners, and property managers looking for roof cleaning near them.
-
Yes — when it’s done correctly. Our soft wash process uses low pressure and carefully selected solutions to break down organic growth without damaging shingles, metal panels, or surrounding plants.
We pre‑wet sensitive landscaping and rinse thoroughly so your property is protected while we clean.
-
Most residential roofs in Knoxville benefit from cleaning every 3–5 years, depending on shade, moisture, and tree coverage. High‑shade areas or roofs with heavy algae and moss may need more frequent treatment.
Commercial and multi‑building properties often follow a regular maintenance schedule so all roofs age more evenly and keep a clean, professional appearance.
-
In many cases, yes. Removing algae, moss, and debris helps prevent trapped moisture and granule loss, which can extend the service life of your roof and delay replacement. It also improves curb appeal and can support property value and tenant satisfaction.
