FAQs
Have questions about roof washing in Passaic County? Here are clear answers from our team.
Yes, when done using proper soft washing methods. Asphalt shingles should never be cleaned with high pressure, as it can strip protective granules and shorten the life of the roof. Soft washing uses low pressure and specialized cleaning solutions to remove algae and buildup safely without damaging shingles.
Black streaks are typically caused by a type of algae called Gloeocapsa magma. It feeds on limestone filler in shingles and spreads in humid conditions common in northern New Jersey. These streaks are not just cosmetic. Over time, they can contribute to shingle deterioration if left untreated.
Professional roof washing removes algae, moss, and lichen at the source using targeted treatment solutions. While visible growth is eliminated, shaded or damp areas may require routine maintenance over time. Proper treatment significantly slows regrowth compared to surface rinsing alone.
Most roofs benefit from cleaning every 2 to 4 years, depending on tree coverage, moisture levels, and sun exposure. Homes in heavily wooded or shaded areas may see faster algae growth and require more frequent treatment to prevent staining and deterioration.
Yes. High-pressure washing can dislodge shingles, strip granules, and force water underneath roofing materials. This can lead to leaks and premature wear. Roof cleaning should always be performed using low-pressure soft washing techniques designed specifically for roofing systems.
Most residential roof washing services take between 2 to 4 hours depending on roof size, pitch, and level of buildup. Larger or more heavily stained roofs may require additional time to ensure even treatment and thorough rinsing.
Yes. Removing algae, moss, and organic buildup helps prevent premature deterioration of shingles. Left untreated, growth can trap moisture and gradually break down roofing materials. Regular professional cleaning can help protect your investment and delay costly roof replacement.
Roof washing pricing depends on roof size, pitch, accessibility, and severity of staining or moss growth. Steeper roofs or homes with heavy buildup may require additional treatment. The most accurate way to determine cost is through a free estimate based on your specific property.
