What Is Roof Cleaning and Moss Removal?
Roof cleaning and moss removal clears biological growth — moss, Gloeocapsa magma algae, and lichen — from a roof with a low-pressure chemical wash that kills the growth at the root. It relies on chemical action rather than pressure washing, which strips the protective granules.
What Roof Cleaning and Moss Removal Is Available in Roseland?
Newark Quality Roofing removes moss, Gloeocapsa magma algae, and lichen from Roseland's tree-shaded postwar colonials, ranches, and split-levels and the borough's Eisenhower Parkway office-park roofs. A cleaning applies a chemical wash at low pressure to kill the growth at the root and rinses the dead material away.

Moss, algae, and lichen establish first on the shaded north-facing slopes under Roseland's mature oak and maple canopy, because shaded slopes hold moisture and grow moss faster, per CSSB and NRCA guidance. The same canopy drops leaf litter into valleys and at roof-to-wall transitions, creating the moisture-holding, nutrient-rich conditions where moss colonies establish, per ARMA algae-and-moss guidance.
A low-pressure chemical wash clears the growth without stripping the protective granules, because ARMA states that pressure-washing an asphalt shingle roof causes granule loss and premature failure of the roof system. A Newark Quality Roofing wash applies the ARMA 50:50 mix of laundry-strength liquid chlorine bleach and water, holds it for the 15-to-20-minute dwell ARMA specifies, and finishes with a low-pressure rinse.
The office-park corridor along Eisenhower Parkway, Becker Farm Road, and Livingston Avenue carries flat and low-slope EPDM, TPO, and modified-bitumen roofs, where biological growth that holds moisture against the membrane accelerates deterioration. A Newark Quality Roofing cleaning matches the chemistry and rinse to the membrane and manages drainage so cleaning solution does not pond on the low-slope deck.
What Roof Cleaning and Moss Removal Problems Are Common in Roseland?




Established moss on Roseland's heavily shaded slopes lifts and curls the shingle leading edges and raises the risk of shingle blow-off during wind events, per ARMA. A Newark Quality Roofing crew removes heavy moss by hand before the wash, then applies the ARMA chlorine-bleach-and-water solution to kill the remaining growth and root structures at the source.
Landscape protection matters where the mature gardens and foundation plantings under Roseland's canopy sit directly below the treatment zone, because the cleaning solution is laundry-strength bleach at a 50:50 mix, per ARMA. A Newark Quality Roofing crew pre-wets and covers plantings beneath the roof edge before applying the solution and rinses thoroughly to dilute any runoff.
Regrowth prevention holds the clean period longer, because proper maintenance extends asphalt-shingle service life by roughly 25 to 30%, per ARMA. Zinc and copper metal molecules inhibit algae growth, per ARMA and Atlas Roofing, but ARMA does not recommend adding strips to an existing roof, so a Newark Quality Roofing lead reserves strip installation for a roof replacement and prevents regrowth on an existing roof with a maintenance wash.

What Is Our Process for Roof Cleaning and Moss Removal in Roseland?

Newark Quality Roofing identifies the growth as moss, Gloeocapsa magma algae, or lichen, rates the roof-covering condition, and protects the landscape before applying any solution. A technician maps moss versus algae across the shaded Roseland slopes and checks for granule loss, because granule loss exceeding roughly 30% of the surface marks a roof beyond cleaning, per GAF and InterNACHI, then pre-wets and covers the plantings beneath the roof edge.

A Newark Quality Roofing crew removes heavy moss by hand, then applies the ARMA 50:50 chlorine-bleach-and-water solution and holds it for the 15-to-20-minute dwell ARMA specifies. Hand removal clears the bulk growth first, because moss lifts and curls the leading edges of shingles, per ARMA, and the low-pressure rinse that follows carries away the dead material without the granule loss a pressure washer causes.

Newark Quality Roofing recommends a maintenance schedule after the cleaning and, at a roof replacement, copper or zinc strips. Proper maintenance extends asphalt-shingle service life by roughly 25 to 30%, per ARMA, and a Roseland office-park low-slope cleaning pairs with an inspection on the NRCA cadence of twice per year, spring and fall, plus an inspection after any major weather event.
