Bangor sits at the heart of the Slate Belt, where the older housing stock, the mature tree cover, and the rolling terrain combine into some of the heaviest roof growth we see anywhere in our service area. The algae and moss are not just a curb appeal problem here. Carriers across Northampton County have been pulling on roof condition during renewals, and Bangor homes show up on the inspection lists right alongside the bigger boroughs.

We work the Slate Belt every week. Our team knows which streets carry the heaviest canopy, where the oldest shingles still cling on, and which carriers have been sending the most notices.

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

Slate roofs are different from asphalt shingles, and we do not apply detergent to original slate. If your Bangor home still has its original slate roof, the right care is typically inspection and repointing rather than washing. If your roof has been replaced with asphalt shingles, which is the case for most Bangor homes today, we are happy to come take a look.
Yes. Carriers across Northampton County are flagging visible algae, moss, and lichen during inspections, and Bangor homeowners are seeing the same notices as the rest of the area. A professional roof washing is the most affordable response, and it addresses the growth that triggers the concern.
The Slate Belt holds onto moisture longer than the rest of the area. Heavy canopy on top of cooler ridge temperatures means a north-facing slope can stay damp for days after a rain that would have dried elsewhere in the valley. That is the surface algae and moss want. The homes that see it earliest are usually the wooded lots out toward East Bangor and up the hill into Pen Argyl.
Yes. The older homes around the borough often have shingles that have weathered through decades of Slate Belt winters, and pressure cracks them outright or accelerates granule loss. We never use pressure on a roof, period. The low-pressure detergent application is safe on every age of asphalt shingle.
The black algae streaking disappears immediately during the wash. Heavier moss and lichen, which we see often on Bangor roofs because of the tree cover, turn bright white right after we apply the detergent. Over the following weeks, the dead growth breaks down naturally and washes away with rain.
We serve Bangor and the rest of the Slate Belt including East Bangor, Roseto, Pen Argyl, Wind Gap, Portland, and Mount Bethel. Our team also covers Nazareth, Bath, Easton, Bethlehem, and the broader Northampton and Lehigh County area.

Why Bangor Homeowners Choose Pressure Brothers

Bangor and the rest of the Slate Belt have a specific roof washing personality. The borough proper has older homes packed close together, many with smaller, simpler rooflines but shingles that have weathered through more shade and moisture than most of the valley. Up into the surrounding hills toward East Bangor and Pen Argyl, the homes spread out into wooded lots where moss and lichen show up earlier and heavier than on the more open streets of the borough.

We treat each section accordingly. The older borough roofs get a longer detergent dwell so the growth breaks down rather than getting pulled off, and the wooded hill homes get extra attention on the shaded north-facing slopes. Every wash includes plant protection, downspout bagging, and a final walkthrough.

Bangor is also one of the few towns where we still see original slate roofs from the quarrying era. Slate is not washed with detergent, but most homes here have moved to asphalt shingles over the years and those are exactly what our process is built for. If you are not sure which you have, we can take a look and tell you straight.
