Pen Argyl sits in the middle of the Slate Belt, with older borough homes packed along the main streets and newer pockets spreading into the surrounding Plainfield Township. The mature tree cover and rolling terrain that make the area so pretty are also what drive the heavy moss and lichen growth we see on roofs here.

A single low-pressure wash handles all of it without any pressure on the shingles. Most Pen Argyl roofs we wash stay clean for years afterward, including the heavily shaded north slopes.

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

Yes. Insurance carriers across Northampton County are flagging visible algae, moss, and lichen on roofs during inspections and renewals, and Pen Argyl homeowners are seeing the same notices as the rest of the Slate Belt. A professional roof washing is the most affordable response.
The mature tree cover and the cooler, moister microclimate across the Slate Belt create exactly the conditions that moss and lichen need to take hold. Homes on the wooded lots out toward Plainfield Township see the heaviest growth, especially on north-facing slopes that stay shaded most of the day.
Yes. The older homes around the borough often have shingles that have weathered through generations of Slate Belt winters, and pressure cracks them outright or strips the protective granules. We never use pressure on a roof. The low-pressure detergent application is safe on every age of asphalt shingle.
Yes. Thicker moss takes longer to fully break down, but the wash is still the right approach. The detergent kills the moss at the root, and over the following weeks the dead growth lifts off naturally with rain. We never scrape thick moss off a roof, because that would damage the shingles underneath.
No. The detergent is designed to break down algae and moss on shingles, not anything growing in your beds. We pre-wet everything around the perimeter before we start, bag the downspouts so runoff is captured before it can reach the lawn, and rinse the landscape again on the way out.
We serve Pen Argyl and the rest of the Slate Belt including Wind Gap, Bangor, East Bangor, Roseto, Portland, and Mount Bethel. Our team also covers Plainfield Township, Nazareth, Easton, Bethlehem, and the broader Northampton and Lehigh County area.

Why Pen Argyl Homeowners Choose Pressure Brothers

Pen Argyl shares much of its character with neighboring Bangor and Wind Gap. The borough has older homes built during the slate quarrying era, with shingled rooflines that have weathered through decades of Slate Belt winters and the shade of mature trees. Out toward Plainfield Township and into the hills, the homes spread onto larger wooded lots, and that is exactly where moss and lichen take hold first.

Our approach changes for each. Older borough roofs get a gentler application that respects the age of the shingles, and the wooded hill homes get extra attention on the north-facing slopes where growth is heaviest. Every Pen Argyl roof wash includes plant protection, downspout bagging, and a final walkthrough.

We work the entire Slate Belt week in and week out. Even when the schedule is full elsewhere, we can usually slot Pen Argyl in around the surrounding stops.
