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 Nutley?
Newark Quality Roofing clears moss, Gloeocapsa magma algae, and lichen from the shaded slopes of Nutley's older single-family homes, two-family stock, and Franklin Avenue and ON3 commercial roofs. A low-pressure chemical wash kills the growth at the root and rinses the dead material away without stripping the protective granules.
Moss settles on the north-facing slopes that stay damp under Nutley's mature street-tree canopy of nine public parks, where it holds moisture against the shingle surface, lifts and curls the leading edges, and raises the risk of wind blow-off, per ARMA. A Newark Quality Roofing crew removes heavy moss by hand before the wash, then targets the shaded slopes that hold moisture and grow moss faster, per CSSB and NRCA guidance.
Gloeocapsa magma algae streaks the asphalt roofs of the township's pre-WWII Colonials and Capes dark, because the algae feeds on the limestone filler in the shingles, per ARMA and Atlas Roofing. A Newark Quality Roofing wash applies the ARMA 50:50 mix of laundry-strength liquid chlorine bleach and water at the 15–20-minute dwell ARMA specifies and rinses the streaking away.
Lichen crusts the shaded shingle surfaces along the Third River and Yantacaw Park corridor and on the slate of the older Lambert-era stock, adhering to the covering until the ARMA chlorine-bleach-and-water solution penetrates it to the root. A Newark Quality Roofing cleaning relies on that chemical action rather than mechanical force, because ARMA states that pressure-washing an asphalt shingle roof causes granule loss and premature failure of the roof system.
What Roof Cleaning and Moss Removal Problems Are Common in Nutley?
Pressure washing strips granules, so a Nutley roof cleaning relies on a low-pressure chemical wash, 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 chlorine-bleach-and-water solution and a low-pressure rinse, killing the growth by chemical action.
Shade-driven regrowth returns on Nutley's tree-canopied north slopes unless the covering is maintained, because shaded north-facing slopes hold moisture and grow moss faster, per CSSB and NRCA guidance. ARMA states that adding zinc or copper strips to an existing roof is not recommended, because the strips require exposed nails that cause leaks over time or break the sealant bond, so a Newark Quality Roofing crew reserves strip installation for a roof replacement and holds an existing Nutley roof clean with a scheduled maintenance wash.
Heavy moss and granule loss mark the point where cleaning no longer restores the covering, because widespread granule loss, edge curling, and brittle sealant signal a covering past restoration, per NRCA, GAF, and InterNACHI general wear guidance. A Newark Quality Roofing pre-cleaning assessment rates the covering condition first, because severe moss build-up causes lateral water movement that reaches the roof deck and leads to moisture damage or leaks, per ARMA.

What Is Our Process for Roof Cleaning and Moss Removal in Nutley?
Newark Quality Roofing identifies the growth, protects the landscaping, and removes heavy moss by hand before any wash. A crew rates the moss, Gloeocapsa magma algae, or lichen and the covering condition, pre-wets and covers the plantings beneath the roof edge, then removes thick moss by hand, because moss lifts and curls the shingle leading edges and raises the risk of blow-off, per ARMA. Across Nutley's tree-lined sections, the crew clears leaf-clogged valleys and gutters as part of the work.
Newark Quality Roofing applies the ARMA 50:50 chlorine-bleach-and-water solution at a 15–20-minute dwell and rinses at low pressure. The crew holds the laundry-strength solution on the surface for the dwell ARMA specifies so the chemistry kills moss, algae, and lichen at the root, then rinses with low-pressure water that carries the dead growth away, because ARMA states that pressure-washing an asphalt shingle roof causes granule loss and premature failure.
Newark Quality Roofing recommends a maintenance schedule and, at a roof replacement, copper or zinc strips. Proper maintenance extends asphalt-shingle service life by roughly 25–30%, per ARMA, so a Newark Quality Roofing lead sets the wash cadence on a shaded Nutley slope and reserves strip installation for a replacement, because ARMA does not recommend adding strips to an existing roof. The crew clears the gutters and downspouts of the rinsed debris before leaving the property.
