Neffs Roof Washing Services
Neffs is a small village in North Whitehall Township, sitting in the rural northern stretch of Lehigh County where wooded lots and Blue Mountain foothills create steady conditions for algae, moss, and lichen on roofs. A single low-pressure wash takes care of all of it.
The algae rinses off the day of the wash and the moss and lichen turn white right after the detergent hits, then break down with the next few weeks of rain. No pressure on the shingles, no scraping.
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 Neffs Homeowners Choose Pressure Brothers
Neffs sits between Schnecksville and Laurys Station, with most homes spread across larger wooded lots that catch their share of north-side moss and lichen. Our low-pressure detergent application handles all of it without any pressure on the shingles, which is what keeps the roof in good condition for years to come.
Every Neffs roof wash includes plant protection, downspout bagging, and a final walkthrough. We are across North Whitehall most weeks of the season, so an extra Neffs stop slots in easily.
