Treichlers Roof Washing Services
Treichlers is a small village along the Lehigh River near Walnutport, in the rural northwestern stretch of Lehigh County. The river moisture and the wooded lots in this part of the valley make for steady algae, moss, and lichen growth on roofs.
A single low-pressure wash handles all three. The detergent kills the growth at the root and the rain finishes the rinse over the next few weeks. No pressure on the shingles, no scraping.
Our Process
Plant and Property Protection
Before anything touches the roof, we protect all plants and landscaping around the home. We bag every downspout to collect leftover detergent and prevent it from reaching the grass or garden beds.
Low-Pressure Detergent Application
We apply a specialized detergent to the entire roof surface using a low-pressure method. The detergent is designed to kill all growth on the shingles, including algae, moss, and lichen. No high pressure is ever used on the roof.
Immediate and Ongoing Results
The algae and black streaking disappear immediately during the wash. Heavier growth like moss and lichen turns bright white after the detergent is applied. Over the following weeks, the dead growth breaks down naturally and washes away with the next good rainstorm. We use this approach specifically to avoid pulling growth off prematurely, which could damage the shingles underneath.

Frequently Asked Questions
Why Treichlers Homeowners Choose Pressure Brothers
Treichlers sits in a wooded riverside pocket of Lehigh County, where steady moisture off the Lehigh River and heavy tree cover combine into the kind of environment moss and lichen love. Most Treichlers roofs we see have heavier growth on the north-facing slopes that stay shaded most of the day.
Our low-pressure detergent application handles all of it without any pressure on the shingles. Every job includes plant protection, downspout bagging, and a final walkthrough.
