Roof Cleaning in Farmingdale and Monmouth County, NJ
Safely remove black streaks, algae, moss, and mildew from your asphalt shingle roof using the ARMA-approved soft wash method. Family-owned and serving Monmouth County for 10+ years.
What Is Soft Wash Roof Cleaning?
Soft wash roof cleaning is a low-pressure cleaning method specifically designed to safely remove algae, mold, mildew, moss, and black streaks from asphalt shingle roofs. Unlike pressure washing, which can strip protective granules and shorten the life of your roof, soft washing uses biodegradable cleaning solutions combined with low-pressure water to kill the algae at the root. This method is approved by the Asphalt Roofing Manufacturers Association (ARMA) and is the only recommended cleaning method for asphalt shingles. At Garden State Pressure Washing in Farmingdale, NJ, we've used the ARMA-approved soft wash method for over 10 years across Monmouth County. Call (732) 307-9605 for a free estimate.
What Are Those Black Streaks on My Roof?
Those dark streaks running down your roof aren’t dirt. They’re caused by a type of algae called Gloeocapsa magma, which feeds on the limestone filler in asphalt shingles. Left untreated, this algae colony continues spreading, holding moisture against your shingles and slowly shortening their lifespan. Even worse, once the algae spreads, it’s only a matter of time before moss and lichen follow, which physically damage shingle granules.
Black streaks are the earliest and most visible sign of roof contamination. The algae itself reduces your roof's reflectivity, which can increase your cooling costs in summer. Our soft wash method kills this algae at the root and prevents regrowth.
Moss and lichen grow between and underneath shingles, trapping moisture and causing shingles to lift, crack, and deteriorate. This is common on shaded, north-facing roof slopes in Monmouth County, especially in Colts Neck, Holmdel, and tree-covered areas of Marlboro.
An untreated roof can lose up to 50% of its expected lifespan. Most homeowner insurance policies won't cover premature roof failure caused by neglected maintenance, which means a $400 cleaning can save a $15,000 replacement.
How Our Soft Wash Roof Cleaning Works
We use a proven 4-step soft wash process that safely cleans your roof without risking damage to shingles, gutters, landscaping, or pets.
Free On-Site Roof Inspection
We visit your Farmingdale, Howell, Freehold, or any Monmouth County property to inspect the roof, check for damaged shingles, and scope the job. No obligation, no pressure.
Property Protection
Before applying any solution, we protect your landscaping, flowers, shrubs, pets, and outdoor furniture. We saturate surrounding plants with water to dilute any runoff and cover sensitive areas.
Soft Wash Application
We apply our ARMA-approved biodegradable cleaning solution using low-pressure equipment. The solution kills the algae, mold, mildew, and moss at the root, not just on the surface.
Rinse and Walk-Through
After dwell time, we gently rinse the roof with low-pressure water. Then we do a full walk-through with you to confirm the results. You only pay when you’re 100% satisfied.

Roof Cleaning FAQs

No. We use biodegradable cleaning solutions and take specific precautions to protect your landscaping. Before we spray, we saturate surrounding plants with water to dilute any runoff. Pets should be kept indoors during cleaning as a precaution, but our solutions are not toxic once diluted.
