Roof Cleaning in Kinnelon, NJ
Low-pressure soft wash that lifts black streaks, moss & algae without touching your shingles.
Roof Cleaning in Kinnelon, NJ
If you live up around Kinnelon, you already know the drill: heavy tree cover, hilly lots, and shade that hangs on longer than you'd like. All of that is great for privacy and summer temperatures, but it's exactly what feeds the black streaks and green moss you see creeping across so many roofs off Kinnelon Road and up in the Smoke Rise area. That staining is gloeocapsa magma algae, and pressure washing it off is a fast way to void a shingle warranty.
We're Gallo Bros, a family-owned North Jersey exterior cleaning company. For roofs we use a low-pressure **soft wash** system that kills the algae and moss at the root instead of blasting the granules off your shingles. It's the method roofing manufacturers actually recommend, and it keeps roofs cleaner for longer than a straight rinse.
Kinnelon's mix of older split-levels, cedar-and-stone colonials, and larger homes on wooded lots each need a slightly different approach, and the slopes around here mean access and drainage matter. We walk the property first, protect your plantings, and give you a straight number before we start. No upsells, no invented promises.

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!”

“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 Kinnelon — FAQ
Why does my Kinnelon roof have black streaks?
Those streaks are a type of algae (Gloeocapsa magma) that thrives in shaded, humid conditions. With Kinnelon's mature tree canopy and north-facing slopes, roofs here hold moisture longer, which is why the staining is so common on this side of Morris County.
Do you pressure wash the roof?
No. We soft wash roofs using low pressure and a cleaning solution that kills algae and moss without stripping shingle granules. High-pressure washing damages asphalt shingles and can void your roof warranty, so we never use it on a roof.
How long will the roof stay clean?
Because soft washing treats the algae at the root rather than just rinsing the surface, results typically last much longer than a pressure rinse. On heavily shaded wooded lots common in Kinnelon, expect a few years, though tree cover and roof direction affect timing.
Will the cleaning solution hurt my landscaping?
We pre-wet and rinse surrounding plants and take care with runoff, especially on the sloped, wooded lots you find throughout Kinnelon. Protecting your property is part of the job we quote up front.
Do you serve all of Kinnelon?
Yes, we cover Kinnelon and the surrounding Morris County towns, including the Smoke Rise area and homes along Kinnelon Road and Boonton Avenue.
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.
