Emmaus Roof Washing Services
Emmaus has some of the prettiest tree-lined streets in Lehigh County, and that mature canopy is exactly why we see so much algae, moss, and lichen on roofs in the borough. With insurance carriers paying closer attention to roof condition, a professional washing is the most affordable way to take care of it before it becomes a coverage issue.
Our process uses a low-pressure detergent application, the only method shingle manufacturers recommend. It kills growth at the root, protects your warranty, and keeps your roof looking great for years.
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 Emmaus Homeowners Choose Pressure Brothers
Emmaus is one of the highest-growth roof environments in our service area, and the tree canopy is the reason. The shaded side streets near the Triangle, the older blocks running off Main Street, and the wooded lots out into East Penn Township all share the same combination of shade and moisture that algae, moss, and lichen need to thrive. Most Emmaus roofs we see have visible growth somewhere, even when the rest of the home looks immaculate.
That makes the wash both more effective and more important. The detergent has more growth to work on, which means a single wash can dramatically change how the home looks from the curb. The low-pressure approach also matters more here, because the older Emmaus homes often have shingles that have weathered through more shade and moisture cycles than roofs in sunnier parts of the valley.
Every Emmaus roof wash includes plant protection, downspout bagging, and a final walkthrough. Whether you are responding to an insurance notice or you have just had enough of the dark streaks on the north slope, give us a call.
