Northampton Roof Washing Services
Northampton Borough sits in one of the most varied roofing zones in the Lehigh Valley, with rows of older homes along Main Street, blocks of mid-century housing near the Atlas Cement legacy lots, and newer developments out toward Allen Township. The dark streaking we see on shingles across the borough is algae, and once it gets going, moss and lichen are usually not far behind. A single visit handles all of it without putting any pressure on the shingles.
The question we hear most often from Northampton homeowners right now is about insurance. Carriers across Lehigh County are reading roofs more carefully than they used to, and our job is to take that worry off your plate before it turns into a coverage problem.
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 Northampton Homeowners Choose Pressure Brothers
Northampton's housing stock spans about a century of borough life, from the older homes built around the Atlas Cement era to the newer streets carved out north of town. That spread of construction dates shapes how we approach each roof. Older borough shingles have already lost some granules to age and cannot take any pressure without losing more. Newer roofs along the Allen Township line are usually still inside a manufacturer warranty window where the wrong wash creates a denied claim years later, not just damage on the day.
So we vary the application. Older borough roofs get a gentler approach and a longer detergent dwell so the algae and moss come apart at the root. Newer roofs get the standard low-pressure detergent process that keeps the warranty intact. Both include plant protection, downspout bagging, and a walkthrough so nothing about the result is a surprise.
If a renewal inspection is on the horizon, same-week scheduling is usually possible. If you are not sure yet whether the roof needs it, we are happy to come look and tell you straight.
