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 Maplewood?
Newark Quality Roofing removes moss, Gloeocapsa magma algae, and lichen from the tree-shaded roofs of Maplewood's architect-designed Tudor, Colonial Revival, and Italian Revival homes and its Maplewood Village and Springfield Avenue storefronts with a low-pressure chemical wash.
Moss, Gloeocapsa magma algae, and lichen settle on the north-facing and shaded slopes that stay damp under Maplewood's mature street canopy and the South Mountain Reservation along its western and northwestern edge, because shaded slopes hold moisture and grow biological growth faster, per CSSB and NRCA guidance. A Newark Quality Roofing cleaning targets those shaded slopes first.
The low-pressure chemical wash relies on 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. A Newark Quality Roofing wash applies the ARMA 50:50 mix of laundry-strength liquid chlorine bleach and water, holds it for the 15–20-minute dwell ARMA specifies, and finishes with a low-pressure rinse.
Maplewood's tree-shaded roofs carry the worst of the load on the township's reservation-edge Wyoming section and its larger period homes on sloped, wooded lots, where leaf litter and organic debris in valleys create the moisture-holding, nutrient-rich conditions where moss colonies establish, per ARMA. A Newark Quality Roofing cleaning clears the heavy moss by hand before the wash, because moss lifts and curls the shingle leading edges, per ARMA.
What Roof Cleaning and Moss Removal Problems Are Common in Maplewood?
Shaded, canopy-heavy slopes are the defining roof-cleaning condition in Maplewood, because tree-lined streets and the South Mountain Reservation on the western edge keep north-facing roofs damp and slow to dry.
Period slate and metal roofs on Maplewood's early-20th-century architect-designed stock take harm from a pressure washer, because ARMA states that pressure-washing causes granule loss and premature failure on asphalt, and high pressure strips a slate roof's weathering surface. A Newark Quality Roofing cleaning matches the chemistry and the low-pressure rinse to the covering rather than blasting the surface.
Severe moss build-up across a Maplewood field causes lateral water movement that reaches the roof deck and leads to moisture damage or leaks, per ARMA, the pattern that follows the reservation-edge canopy on the Wyoming section and Memorial Park's wooded lots. A Newark Quality Roofing cleaning removes the heavy moss by hand before the wash to stop the granule lift and the deck moisture.
Foundation gardens and mature landscaping sit beneath most Maplewood roofs, so the ARMA solution, laundry-strength bleach at a 50:50 mix, calls for protection of the plantings below. A Newark Quality Roofing crew pre-wets and covers the plantings before the wash and rinses thoroughly after, because the solution is laundry-strength bleach, per ARMA.

What Is Our Process for Roof Cleaning and Moss Removal in Maplewood?
Newark Quality Roofing identifies the growth as moss, Gloeocapsa magma algae, or lichen, rates the roof-covering condition, and sets the cleaning chemistry, because widespread granule loss that exposes the asphalt mat marks a roof beyond cleaning, per GAF and InterNACHI.
Newark Quality Roofing pre-wets and covers the foundation plantings, then removes heavy moss by hand and applies the ARMA 50:50 laundry-strength chlorine-bleach-and-water solution for the 15–20-minute dwell ARMA specifies. Moss removed first lifts and curls the shingle leading edges and raises the risk of wind blow-off, per ARMA, and the solution kills the moss, Gloeocapsa magma algae, and lichen at the root by chemical action.
Newark Quality Roofing rinses with low-pressure water that carries away the dead growth, because ARMA states that pressure-washing an asphalt shingle roof causes granule loss and premature failure of the roof system. A Newark Quality Roofing lead recommends a maintenance schedule afterward, because proper maintenance extends asphalt-shingle service life by roughly 25–30%, per ARMA.
