Roof Cleaning in Saddle River, NJ
Low-pressure soft wash that lifts black streaks, moss & algae without touching your shingles.
Roof Cleaning in Saddle River, NJ
If you live in Saddle River, you already know the homes here aren't your average subdivision builds. A lot of the properties off Chestnut Ridge Road, East Allendale Road, and up along the wooded lots near the Saddle River County Park sit under heavy tree cover — and that shade is exactly why so many roofs in town end up with dark streaks, green moss, and that grimy look on the north-facing slopes. Those black streaks are actually a type of algae (Gleocapsa magma) that thrives in our humid North Jersey summers and the moisture that lingers under all those mature oaks and maples.
At Gallo Bros, we're a family-owned exterior cleaning company based in the area, and we handle roof cleaning the right way for Saddle River's mix of home styles — larger colonials, custom builds, and estates with asphalt shingle, slate, and cedar shake roofs. We don't blast your roof with high pressure. We use soft washing, a low-pressure method with the proper cleaning solutions that kills the algae and moss at the root without cracking shingles or voiding your manufacturer warranty.
Between the freeze-thaw winters, wet springs, and shaded lots, roofs here need attention. We'll give you an honest look and a straight quote — no pressure, no gimmicks.
- Local crew that knows Saddle River homes
- Soft-wash & low-pressure methods that protect your surfaces

The house looks brand new again, every detail was handled with care, and the difference is unbelievable. They were professional, thorough, hardworking, and took real pride in their work. It’s rare these days to find a company that exceeds expectations, but they absolutely did. Highly, highly recommend the Galo Brothers to anyone looking for top notch service and incredible results!”
Bruce Bosland
“Gallo Bros powerwashing team headed up by Joe, did a great job on our exposed, lakefront home. 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.”

Roof Cleaning in Saddle River — FAQ
Will pressure washing damage my roof shingles?
It can, which is why we don't do it. High pressure strips the protective granules off asphalt shingles and can force water under them. For Saddle River roofs we use soft washing — low pressure plus a cleaning solution that safely removes algae, moss, and stains without damaging the material.
Why does my roof have black streaks?
Those streaks are algae, and they're extremely common on shaded, tree-covered lots like many in Saddle River. The north-facing side of the roof usually gets it worst because it stays damp longer. Soft washing treats the algae directly so it clears up and stays gone longer than a rinse would.
Do you clean cedar shake and slate roofs?
Yes. A lot of the custom and older homes around town have cedar shake or slate, and both need a gentle approach. We adjust our method and solution strength for the roofing material rather than using one setting on everything.
When is the best time to have a roof cleaned in North Jersey?
Spring through fall is ideal, since temperatures make the cleaning solution work best. That said, if moss has built up over a wet season, it's worth addressing before winter freeze-thaw cycles let it work deeper into the shingles.
Are you local to Saddle River?
We're a family-owned company serving Saddle River and the surrounding Bergen County towns. We know the local home styles, the tree cover, and how our seasons affect roofs here.
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.
