Soft washing protects your shingles. Pressure washing strips off granules and voids warranties. Most shingle manufacturers only recommend soft wash. It’s gentler but kills algae better.
Most roofs stay clean for 2 to 4 years in Long Island’s climate. Shaded roofs might need cleaning sooner. We use treatments that slow regrowth compared to just pressure washing.
Not when we do it. We cover all plants and shrubs before starting. Our biodegradable cleaners won’t harm vegetation. Everything gets rinsed properly so your yard stays safe.
Spring and fall work best. Avoid winter when solutions freeze and summer’s extreme heat. Mild weather helps cleaners work better and protects your landscaping during the process.
