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 Cedar Grove?
Newark Quality Roofing clears moss, Gloeocapsa magma algae, and lichen from roofs across Cedar Grove's tree-shaded postwar ranches, split-levels, colonials, and Cape Cods and its Pompton Avenue / Route 23 storefronts. A roof cleaning applies a low-pressure chemical wash that kills the growth at the root without stripping the protective granules.
Moss establishes on the north-facing slopes that stay damp under Cedar Grove's reservation-edge and street-tree canopy, lifting and curling the shingle leading edges and raising the risk of wind blow-off, per ARMA. A Newark Quality Roofing cleaning removes the heavy moss by hand before the wash.
Gloeocapsa magma algae streaks the field dark, the most prevalent roof-discoloration algae, which feeds on the limestone filler in asphalt shingles, per ARMA and Atlas Roofing. A Newark Quality Roofing wash applies the ARMA 50:50 chlorine-bleach-and-water solution to clear the streaking, and the dead growth rinses away through later rain.
Lichen crusts grey-green onto shaded shingle surfaces and adheres to the granule, the most stubborn of the three growths. A Newark Quality Roofing wash holds the ARMA solution on the surface for the 15–20-minute dwell ARMA specifies to penetrate the growth to the root, then finishes with a low-pressure rinse.
What Roof Cleaning and Moss Removal Problems Are Common in Cedar Grove?
Reservation-edge and street-tree canopy is the defining cleaning condition in Cedar Grove, because the wooded edges of Mills and Hilltop reservations and the township's mature deciduous canopy press shade onto north-facing slopes. Shaded slopes hold moisture and grow moss faster, per CSSB and NRCA guidance, so a Newark Quality Roofing cleaning targets them first.
Pressure washing strips the protective granules, because ARMA states that pressure-washing an asphalt shingle roof causes granule loss and premature failure of the roof system, and granule loss exceeding roughly 30% of the surface is the common rule-of-thumb for beyond repair, per GAF and InterNACHI. A Newark Quality Roofing cleaning uses chemical action at low pressure instead.
Severe moss build-up across the field causes lateral water movement that reaches the roof deck and leads to moisture damage or leaks, per ARMA. On Cedar Grove's low-pitch ranch and split-level roofs the debris and growth sit longer, so a Newark Quality Roofing cleaning targets the shaded slopes and valleys first and pairs the wash with debris clearing.
Low-slope membranes on the Pompton Avenue / Route 23 storefronts hold biological growth and moisture against the surface, and the cleaning chemistry and rinse match EPDM, TPO, and modified-bitumen rather than asphalt. A Newark Quality Roofing crew manages drainage during the rinse so cleaning solution does not pond on the membrane.

What Is Our Process for Roof Cleaning and Moss Removal in Cedar Grove?
Newark Quality Roofing identifies the growth as moss, Gloeocapsa magma algae, or lichen, rates the roof-covering condition, and removes heavy moss by hand before the wash. A technician checks for granule loss, because granule loss exceeding roughly 30% of the surface marks a roof beyond cleaning, per GAF and InterNACHI, and moss lifts and curls the shingle leading edges, per ARMA.
Newark Quality Roofing applies the ARMA 50:50 laundry-strength chlorine-bleach-and-water solution at low pressure, holds it for the 15–20-minute dwell ARMA specifies, and finishes with a low-pressure rinse. A crew pre-wets and covers the plantings beneath the roof edge before the application, because the solution is laundry-strength bleach, per ARMA, and the wash kills moss, algae, and lichen by chemical action.
Newark Quality Roofing pairs the cleaning with an inspection on the NRCA twice-per-year cadence and recommends a maintenance schedule rather than strips on an existing roof. Proper maintenance extends asphalt-shingle service life by roughly 25–30%, per ARMA, and ARMA does not recommend adding zinc or copper strips to an existing roof, because the strips require exposed nails that cause leaks or break the sealant bond.
