Roof Cleaning in Ridgewood, NJ
Low-pressure soft wash that lifts black streaks, moss & algae without touching your shingles.
Roof Cleaning in Ridgewood, NJ
If you drive around the Village of Ridgewood, you'll notice a lot of older colonials, Tudors, and center-hall homes — many with mature shade trees hanging right over the roofline. That shade is beautiful in July, but it's also why so many roofs here end up with those dark streaks and green moss patches. Those aren't dirt. It's Gloeocapsa magma algae and moss feeding on your shingles, and pressure washing will only tear the granules off and void your warranty.
Gallo Bros is family-owned and works throughout North Jersey, including the neighborhoods off East Ridgewood Ave and up toward the Glen Rock and Ho-Ho-Kus lines. We use a **soft wash** — low pressure with a cleaning solution that kills the algae and moss at the root, not just rinses the surface. It's the method asphalt shingle manufacturers actually recommend.
Bergen County weather doesn't help: humid summers, wet springs, and snow that sits on north-facing slopes all winter. That moisture keeps roofs feeding organic growth year-round. We'll come take a look, tell you honestly whether your roof needs a full clean or just a spot treatment, and give you a straight price. No pressure, no gimmicks.

They went above and beyond to remove dirt and mildew from our house siding, soffits and multiple bluestone patios and walkways, as well as our dock and wood furniture. They also took great care to avoid or work around multiple bird nests which had recently hatched babies pre fledge. I will definitely call them in the future!”

“We hired Gallo Bros Power Washing to power wash, re-sand and seal our 20 year old paver patio and front walk. They also performed a few repairs and reset a few areas that needed attention. We had never had this done professionally before. From the beginning estimating phase to the final coat of sealer, we were very happy with the services provided, the price and the final result, which they also warrantee for 1 year. I highly recommend Gallo Bros. Power Washing and will use them for other services in the future.”

“Gallo Bros did an amazing job power-washing my home and roof. They assured me that if I had any concerns they would avail themselves to resolve them. After the cleaning a few leaves blocked the gutter after a heavy rain. They responded quickly and courteously, removing the blockage touched up ,y skylights as well. Before leaving they made sure I was satisfied. Oscar and his team came a few weeks later and sanded and sealed my paver walkway. They were polite and professional, explaining what they were doing, how long it would take, and instructions to ensure the best possible result. What I loved most was the professionalism in their communication. There were several days that we were rescheduled due to heavy rains and storms. The first thing they assured us of was their intent to make sure the job was done correctly. They would not come out to do the work, only to have it washed away. They stayed in contact every step of the way and I felt more than comfortable that the job would get completed the right way. If they couldn’t reach h me by phone they always left a voicemail or sent a text. I just happened to call them first in my search for roof cleaning, but I will never have to look further for these services again. I was really so impressed. Thank you Gallo Bros!”

Roof Cleaning in Ridgewood — FAQ
Do you pressure wash the roof?
No. We soft wash roofs using low pressure and a cleaning solution. High pressure strips the protective granules off asphalt shingles and can cause leaks, so we never blast a roof.
Will roof cleaning damage my landscaping?
We take care to protect plants and shrubs around the house — pre-wetting greenery and rinsing afterward. A lot of Ridgewood homes have established landscaping, so we treat it carefully.
How long do the black streaks stay gone?
Because soft washing kills the algae at the root, results typically last for years. Homes under heavy tree cover may see growth return sooner, which is common in shadier parts of the Village.
Do you serve areas near Ridgewood too?
Yes. We're a North Jersey company and regularly work the surrounding Bergen County towns, including Glen Rock, Ho-Ho-Kus, Midland Park, and Wyckoff.
How much does roof cleaning cost?
It depends on roof size, pitch, and how much growth is present. We give free, honest estimates — sometimes a spot treatment is all you need instead of a full clean.
How much does roof cleaning cost in NJ?
It ranges widely — from a few hundred dollars for a small ranch to several thousand for a large, steep or complex roof. Size, pitch, material, access and how much algae has built up all factor in. You get a firm price up front, free.
Will roof cleaning damage my shingles?
No. We soft wash with low pressure and a cleaning solution — the method asphalt-shingle makers recommend. High-pressure washing is what damages roofs; we never do that on a roof.
What are the black streaks on my roof?
That's a hardy algae called Gloeocapsa magma. It feeds on the limestone in your shingles and spreads in New Jersey's humidity. Soft washing kills it at the root, not just the surface.
How long does a roof cleaning last?
Usually 2–4 years. Because soft washing kills the algae instead of just rinsing it, the clean lasts far longer than a quick power-rinse.
