Soft washing that removes the black streaks, algae and moss shortening your roofs life at low pressure that never lifts a shingle or voids a warranty.
The dark streaks running down north-facing roof slopes across Long Island have a name: Gloeocapsa magma. Its a blue-green algae, and its not cosmetic.
It feeds on the limestone filler in asphalt shingles, and as it spreads it holds moisture against the roof surface around the clock. That constant dampness breaks down the shingle mat, loosens granules, and shortens the life of the roof a roof rated for 30 years can fail well short of it under heavy growth.
Moss and lichen are worse. Where algae stains, moss and lichen root. Moss lifts the edges of shingles as it grows underneath them, opening paths for water. Lichen bonds so tightly it pulls granules off when disturbed. Both take hold fastest on the shaded, north-facing slopes and under overhanging trees exactly the conditions Long Islands wooded neighborhoods provide.
The staining spreads because its living. Left alone, it doesnt just look worse it costs you roof.
You cannot pressure wash a roof. High pressure strips the protective granules off asphalt shingles, drives water under the courses, and takes years off the roof in a single afternoon. Its the fastest way to turn a cleaning bill into a replacement bill.
Soft washing is the answer, and its what the industry standard calls for. We apply professional-grade cleaning solutions at low pressure that break the algae, moss and lichen down at the root and kill the spores. The growth releases, the roof rinses clean, and because the organism is actually dead it stays clean far longer than any pressure treatment.
This is also the method the asphalt shingle industry endorses soft washing keeps your roof within its manufacturer warranty, where high-pressure cleaning voids it.
Before we start, we protect the property. Landscaping and any plantings below the roofline are pre-wet and covered, and everything is rinsed again when we finish.
Most Long Island roofs benefit from cleaning every two to three years, sooner where conditions push growth.
For north-facing slopes under heavy tree cover, homes surrounded by mature trees, and anywhere moss has already started it comes back faster once established.
For open, sunny roofs with good airflow and little overhang.
Catching it while its still staining rather than mossing is the difference between a straightforward soft wash and a roof thats already lost life.

Most exterior damage were asked to fix was caused by cleaning. Knowing which surfaces take pressure and which need chemistry is the entire job.
Members of the Power Washers of North America an industry association with standards around method, insurance, and environmental practice. Very few Long Island companies hold it.
Landscaping pre-wet and covered, fixtures shielded, everything rinsed after. It takes longer. Its why we dont leave damage behind.

Most homeowners combine these one mobilization, one visit, better pricing than booking separately.
No the opposite. We soft wash at low pressure, which is the method the asphalt shingle industry endorses and which keeps your warranty intact. High-pressure roof cleaning is what strips granules and voids warranties, and its exactly what we avoid.
Gloeocapsa magma a blue-green algae that feeds on shingle filler and spreads across shaded, north-facing slopes. It holds moisture against the roof and shortens its life, so its worth removing rather than living with.
Completely. You cant pressure wash a roof without stripping granules and driving water under the shingles. Roof cleaning is soft washing low pressure with cleaning solutions doing the work, killing the growth at the root.
Slower than youd think, because soft washing kills the spores rather than just rinsing off whats visible. On a shaded, wooded lot it returns eventually; on an open roof it can stay clean for years.
Yes. Moss is treated so it releases and dies rather than being scraped or blasted off scraping lifts shingle edges and pulls granules. We let the chemistry do the work and clear the debris gently.
Yes. We use biodegradable, professional-grade solutions and pre-wet and cover landscaping below the roofline, then rinse everything afterward. Pets should stay inside while we work.
Most homes take a few hours depending on roof size, pitch and how much growth has built up. Heavy moss or lichen takes longer. Well give you a realistic window when we quote.
