Nazareth Roof Washing Services
Nazareth roofs are seeing the same insurance pressure as the rest of Northampton County. From the older borough row homes along Main Street to the newer developments out in Upper Nazareth Township, algae, moss, and lichen growth can raise red flags during inspections and renewals.
A professional roof washing is the most affordable way to address it. Our process is a low-pressure detergent application, the only method shingle manufacturers recommend, with no pressure on the shingles at all.
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 Nazareth Homeowners Choose Pressure Brothers
Nazareth has a real split in its housing stock. The older borough section along Main Street and the side streets has tightly packed row and detached homes, often with shingles that are well-past their first decade and have already lost some granules to age. Up the hill into Upper Nazareth and out toward the Bushkill Township line, the homes are newer and the lots are larger, with more tree cover that drives moss and lichen growth on the north-facing slopes.
Our approach changes for each. The older borough roofs get a gentler application, since pressure or aggressive scrubbing on aged shingles will accelerate granule loss. The newer Upper Nazareth homes get the standard low-pressure detergent process, with extra attention around the wooded north-facing sections where heavier moss takes hold. Every job includes plant protection, downspout bagging, and a final walkthrough.
