Whitehall Township Roof Washing Services
Whitehall Township covers a lot of ground, from the postwar Capes in Fullerton to the older blocks around Cementon to the newer developments along MacArthur Road and out into Egypt. The roofs across the township vary just as much, and they all face the same growing pressure from insurance carriers asking about algae, moss, and lichen.
A professional low-pressure roof wash handles all of it safely, with no pressure on the shingles, in a single visit. It is the only method shingle manufacturers recommend, and it is what we use on every job.
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 Whitehall Township Homeowners Choose Pressure Brothers
Whitehall is one of the most varied townships in Lehigh County when it comes to roof conditions. The Fullerton Cape Cods from the postwar years have shorter, simpler rooflines, but the shingles are often older and more brittle than they look. Cementon homes carry decades of fine industrial residue that bonds with airborne algae, which means the wash sometimes needs a longer dwell to fully break down what has settled. The newer Egypt and MacArthur Road developments have larger, more complex rooflines that are still well within their manufacturer warranty windows, where the wrong washing method causes problems down the road.
We adjust our process for each of these. Older Fullerton roofs get a gentler approach with no pressure on aged shingles. Cementon homes get a longer dwell time so the detergent has time to lift the residue along with the algae. The newer developments get the standard low-pressure detergent process that protects the warranty. Every job includes full plant protection, downspout bagging, and a final walkthrough.
If you have a renewal inspection coming up or your insurance carrier has already flagged your roof, give us a call. We work across all of Whitehall Township and the neighboring boroughs and can usually fit you in before an inspection deadline.
