Walnutport sits along the Lehigh River at the Northampton-Carbon County line, with a mix of older borough homes near the riverfront and newer pockets spreading out into the surrounding Lehigh Township. The river moisture and the wooded lots make for steady algae, moss, and lichen growth on roofs across the borough.

A single low-pressure wash handles all three. The detergent works at the root and the rinse is gentle enough to leave older borough shingles intact.

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

The renewal-inspection notices coming out of Walnutport read pretty consistently. They flag visible algae or moss on the shingles and give you a window to address it. A single wash usually closes the issue. Send us the notice and we will tell you how quickly we can fit you in before the deadline.
Yes, with the right method. The older homes near the riverfront have shingles that have weathered generations of Lehigh River weather, and they cannot tolerate any pressure. Our low-pressure detergent application is safe even on the most weathered roofs.
The Lehigh River runs right past the borough, and the steady moisture coming off it keeps the air damper than it is even a few miles inland. Combine that with the wooded lots out into Lehigh Township and the shingles do not get the chance to dry that they would on an open lot somewhere else.
Yes. Even on newer shingles still under manufacturer warranty, pressure strips protective granules and is grounds for a denied warranty claim. Our process never uses pressure.
We serve Walnutport and all of Lehigh Township along with Cherryville, Danielsville, Treichlers, Bath, and the broader northern Northampton County area. Our team also covers Bethlehem, Nazareth, and into Lehigh County.

Why Walnutport Homeowners Choose Pressure Brothers

Walnutport is one of the older boroughs in northern Northampton County, with shingled rooflines that have weathered through generations of Lehigh River winters. The older borough homes near the river have shingles that need a gentler approach, while the newer homes spreading out into Lehigh Township have larger rooflines often still under manufacturer warranty.

We adjust our process for each. Either way, no pressure ever touches the shingles. Every Walnutport roof wash includes plant protection, downspout bagging, and a final walkthrough.
