Roof Cleaning Rutherford, NJ
A roofer in Rutherford can clean black algae streaks, lichen and grime off a roof using a low-pressure soft wash that does not strip shingle granules, while protecting plants, siding and gutters below. Dial (551) 380-1579 to talk with a local roofer about cleaning your roof.
Those black streaks running down a shingle roof are almost always algae, not dirt or mold from inside the house. It forms a dark outer layer that shows up as streaks following the path of rainwater. It is mostly a cosmetic problem at first, but lichen and moss tend to move in alongside it, and those do damage shingles over time.
How the roof is cleaned matters more than how clean it looks afterward. A pressure washer strips granules, lifts shingle tabs and drives water under the roofing, which is why low-pressure methods are the standard. With a soft wash, the cleaning solution does the work, not water pressure.
A few details help plan the cleaning. Note whether the stains are black streaks, green patches, gray or crusty spots of lichen, or clumps of moss, and which slopes they cover. Say whether the roof is asphalt, tile, metal or wood, and what is planted along the house.
Many roof cleaning calls in Rutherford also turn up a need for roof moss removal or gutter cleaning.

What happens during a roof cleaning
Here is how a roofer typically cleans a roof.
Inspect the roof
The roofer checks the roof material, the type of growth and the condition of the shingles, flashing and vents before cleaning. Problems hidden under the grime often show up here.
Cover the plants
The crew wets down plants and grass and moves outdoor furniture away from the walls. Gutter runoff can be directed away from planted areas.
Treat the roof
A low-pressure sprayer applies the solution evenly, letting it soak in to kill the growth. Shingles, tile and metal each get a solution suited to them.
Rinse gently
After the solution works, loose debris is swept from valleys and the gutters are cleared. Lichen often releases over time after it dies.
Rinse the plants
Plants, siding and walkways are rinsed again with clean water, and the roof is checked one last time. The roofer notes any shingles or flashing that need repair.
What is included

Roof Soft Wash Rutherford, NJ
Soft washing is the low-pressure method used on most roofs, relying on a cleaning solution rather than force. The cleaning mix breaks down the growth and its root structure, not just the visible stain. Because it kills the growth rather than scraping it off, the roof stays clean longer than with pressure washing.
Most Rutherford homeowners with streaked shingles are well served by a soft wash. Plants and grass are watered ahead of time and rinsed again afterward so the runoff is diluted. Results show quickly on algae, while lichen releases more slowly.

Roof Cleaning Service Rutherford, NJ
A roof cleaning service handles the full job, from protecting the yard to treating the roof and clearing gutters. A wet, treated roof is extremely slippery, which is why roof cleaning is not a good do-it-yourself job. While cleaning, a roofer can flag loose shingles, cracked tiles and failing pipe boots.
Many Rutherford roof cleanings end with clearing the gutters and downspouts. After cleaning, metal strips near the peak can keep algae and moss from coming back as quickly. Cutting back overhanging limbs lets the roof dry faster.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Rutherford, NJ have the roof checked in the fall and again after the snow melts.

Roof Cleaning questions
Can I pressure wash my roof?
Pressure washing is not recommended for asphalt shingle roofs. The force blasts off granules and can drive water under the shingles or crack tile. Soft washing is the safe alternative.
Is cleaning a roof worth it?
Algae is mostly cosmetic, but lichen and moss can shorten roof life. Cleaning also makes it easier to see loose shingles and worn flashing. The benefit depends on using a soft wash.
Why does my roof have dark stains?
Those dark stains are almost always airborne algae, not dirt. The algae forms a dark outer coating that shows up as long streaks. Newer shingles with copper granules resist it better.
How often should a roof be cleaned?
The schedule depends on how fast growth returns. Sunny roofs with good airflow stay clean longer. Preventive strips help keep the roof clean longer.
How are plants protected during roof cleaning?
Landscaping is watered down before, during and after the wash. Delicate plants can be covered, and downspouts can be directed away from beds. Mention any prized plants before work starts.
