Center Valley sits in the heart of the Saucon Valley, with larger lots, mature landscaping, and the kind of tree cover that creates ideal conditions for algae, moss, and lichen on roofs. Insurance carriers across Lehigh County have been pulling on roof condition harder than they used to, and the larger Center Valley properties are showing up on those inspection lists.

The complex rooflines that come with estate-style homes need a careful application, not a powerful one. A low-pressure detergent wash reaches every face, dormer, and hip the way pressure cannot.

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

Yes. Insurance carriers across Lehigh County are paying closer attention to roof condition, and Center Valley homes are showing up on inspection lists alongside the rest of the area. A professional roof washing is the most affordable response, and we can usually get you scheduled before an inspection deadline.
The larger Center Valley homes often have rooflines with multiple slopes, dormers, and hipped sections, and the right application matters more here than almost anywhere else. We apply the detergent in sections so every face gets the same coverage. The low-pressure method has a real advantage on these roofs since we are not trying to project pressurized water at difficult angles.
Yes. Many Center Valley homes have roofs that are still well within their manufacturer warranty windows, and pressure washing those shingles is grounds for a denied warranty claim down the road. Our low-pressure detergent application is the method the manufacturers actually recommend.
The mature canopy across Center Valley combined with the ridge shade from the South Mountain range creates a shaded, moist microclimate where algae, moss, and lichen thrive. Homes set back into wooded lots see it first, especially on north-facing slopes. Our detergent is designed for exactly that growth.
No. Center Valley homes often have significant landscaping investments, and we treat them with extra care. We wet down all plants and shrubs before we start, bag every downspout to capture leftover detergent, and rinse the landscaping again when we finish.
We serve Center Valley and all of Upper Saucon Township along with Coopersburg, Hellertown, Lower Saucon Township, Limeport, Old Zionsville, and Emmaus. Our team also covers Bethlehem, Macungie, and the broader Lehigh and Northampton County area.

Why Center Valley Homeowners Choose Pressure Brothers

Center Valley has some of the most well-kept homes in southern Lehigh County, set on generous lots along the Saucon Creek corridor and through the surrounding Upper Saucon Township. The combination of mature canopy, ridge shade from the South Mountain range, and the moisture the Saucon Creek pulls through the valley creates a roof environment where algae, moss, and lichen show up early and stay until something addresses them.

We adjust our approach for the larger, more complex rooflines that are common across Center Valley. Estate-style homes with multiple slopes, dormers, and hipped sections get section-by-section detergent application so every face gets the same coverage. Newer rooflines near the DeSales University area and the Promenade Shops corridor get the standard low-pressure detergent process that protects the manufacturer warranty.

Every Center Valley roof wash includes thorough plant protection for the established landscaping, downspout bagging, and a final walkthrough so nothing about the result is a surprise.
