Roof Washing in Argyle, TX
Soft wash roof cleaning that removes black algae streaks and buildup without stripping granules or voiding your shingle warranty.
Roof washing begins with a look at the roof itself, checking for soft spots, loose shingles, or existing damage before anyone applies anything. A roof safe cleaning solution formulated to kill the black algae behind those streaks, along with any moss or lichen, gets applied starting at the ridge and working down. It sits for a dwell period, then gets rinsed at low pressure, never with a pressure washer.
Gutters, downspouts, AC units, and landscaping below the roofline are protected from runoff during the process, since the chemical is strong enough to do its job on algae but needs to be kept off plants and finishes.
The damage from doing this with a pressure washer shows up as granule loss, the little stone coating that protects shingles from UV and weather. Once that is stripped, shingles wear out faster, and it often looks like bald or lighter patches rather than obvious damage right away. Most shingle manufacturers void their warranty outright if a pressure washer touches the roof. Walking the roof more than necessary also risks cracking shingles or tiles underfoot.
