Roof Cleaning in Oradell, NJ
Low-pressure soft wash that lifts black streaks, moss & algae without touching your shingles.
Roof Cleaning in Oradell, NJ
If you've noticed dark streaks running down the north-facing side of your roof here in Oradell, you're not imagining it. That black staining is *Gloeocapsa magma*, a hardy algae that thrives in our humid North Jersey summers and clings to the asphalt shingles you'll find on the vast majority of homes around town — from the older colonials and center-hall homes near Kinderkamack Road to the split-levels and capes tucked along the quieter streets off Oradell Avenue.
We're Gallo Bros, a family-owned exterior cleaning company, and we handle roofs the right way: soft washing. Instead of blasting shingles with high pressure — which strips granules and voids most manufacturer warranties — we apply a low-pressure cleaning solution that kills the algae, moss, and lichen at the root. It rinses clean and keeps working after we leave.
Oradell's tree-heavy lots don't help. All that shade near the Oradell Reservoir and along the older, canopied blocks means roofs stay damp longer and grow moss faster than sun-baked ones. If your shingles look older than they are, a soft wash often buys you years before you'd ever need a replacement.

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 Oradell — FAQ
Will roof cleaning damage my shingles?
Not the way we do it. We use soft washing — low pressure plus a cleaning solution — never a pressure washer aimed at your shingles. High pressure removes protective granules and can void your roof warranty, which is exactly why we don't use it.
How long does a clean roof stay looking good in Oradell?
Typically several years, though shaded, tree-lined lots near the reservoir may regrow algae a bit sooner than sunnier, exposed roofs. Keeping gutters clear and trimming overhanging branches helps it last longer.
What causes the black streaks on my roof?
It's algae, not dirt. Our humid summers and the moisture that lingers on North Jersey roofs create ideal conditions for it to spread, especially on north-facing slopes that get less sun.
Do you do the whole exterior or just the roof?
Both. A lot of Oradell homeowners have us soft wash the roof and house siding in one visit, and add gutters, windows, or the driveway and pavers while we're there. Just ask when you get your estimate.
When is the best time of year to clean a roof?
Spring through fall works best in NJ, since the solution works best above freezing. Many folks book after winter to clear off the season's buildup, or in fall before leaves and moisture pile up.
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.
