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!”
Cathy Marshall
“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.”

“I wanted power wash my backyard deck for a long time but they said it cannot be done due to the equipment was not accessible however Gallo Brothers had very long 400feet hose and did the power wash which was not done for many years. I am very happy they did a very good job specially Mark was very helpful to do front porch and walkway. It is speck clean this is exactly what I wanted to do. I do highly recommend Gallo Bothers meticulous job.”

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.
