Roof Cleaning in Louisville, KY
Low pressure roof cleaning that removes black streaks and moss from asphalt shingles without stripping granules or voiding warranties.

The black streaks running down Louisville roofs are alive. Gloeocapsa magma, an airborne bacteria, lands on shingles and feeds on the crushed limestone inside them, and it thrives wherever humidity stays above sixty percent. Louisville sits above that line most of the year, which is why streaked roofs are on every street in Jefferson County.
Never pressure wash a shingle roof
A pressure washer takes the granules off shingles along with the streaks, which removes years of roof life in an afternoon and usually voids the manufacturer warranty. We clean roofs the way shingle manufacturers direct, with a low pressure application that lands softer than rainfall and lets the solution do the killing. Streaks fade immediately and disappear completely as weather rinses the dead growth away over the following weeks.
More than looks
Roof algae holds moisture and heat against your shingles, eats their mineral base, and loosens granules early. Cleaning it is maintenance, not cosmetics. It also matters at sale time, because streaked roofs come up in inspections and appraisals across Louisville, and a clean roof photographs years younger on a listing.
Every roof gets the right method
Asphalt shingle is most of our work, but Prospect and Anchorage estates bring cedar shake, slate, and metal, and each gets a treatment matched to the material. Moss on north facing slopes under Louisville tree canopy gets treated at the root so it releases without prying that would damage shingles.
