Roof Cleaning in Flanders, NJ
Low-pressure soft wash that lifts black streaks, moss & algae without touching your shingles.
Roof Cleaning in Flanders, NJ
If you live in Flanders and you're seeing dark streaks running down your shingles, you're looking at Gloeocapsa magma — a roof algae that thrives in our humid North Jersey summers and the shade thrown by all the mature oaks and maples around here. It's not dirt you can just rinse off. Pressure washing a roof strips granules and voids most shingle warranties, which is exactly why we don't do that.
Gallo Bros uses a **soft wash** approach: low-pressure application with the right cleaning solution that kills the algae, moss, and lichen at the root instead of blasting your shingles apart. That's the method that keeps a roof looking clean for years, not weeks. We're a family-owned crew that works these Morris County towns every week, from the older colonials and split-levels off Route 206 to the newer developments up toward Bartley Road and the Flanders-Drakestown side.
We show up when we say we will, we don't upsell you on work you don't need, and we treat your landscaping and gutters like they matter. No franchise scripts, no invented "reviews," just straight roof cleaning done right. Call us for a look and an honest price.
- Local crew that knows Flanders homes
- Soft-wash & low-pressure methods that protect your surfaces
- Licensed, insured & background-checked

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 Flanders — FAQ
Do you pressure wash roofs in Flanders?
No. We soft wash. High pressure tears the protective granules off asphalt shingles and can void your manufacturer's warranty. We use low-pressure application and a cleaning solution that kills algae and moss at the source, so your roof stays clean far longer.
What are those black streaks on my roof?
Almost always a blue-green algae called Gloeocapsa magma. It's extremely common on Flanders homes because of our humid summers and all the tree cover from the surrounding woods and older neighborhoods. It spreads on the north-facing and shaded sides first.
Will roof cleaning damage my landscaping?
We take real precautions — pre-wetting and rinsing plants, protecting beds, and managing runoff. Being a small family crew, the same people who do the work are the ones who care about not wrecking your yard.
How often should a roof be cleaned in North Jersey?
For most Flanders homes, every few years is plenty, though heavily shaded roofs near tree lines may need it sooner. We'll tell you honestly if you don't need it yet — we're not going to invent a problem.
Do you serve the whole Flanders area?
Yes. We cover Flanders and the greater Mount Olive Township area, plus neighboring Morris County towns. If you're near Route 206, Bartley Road, or the Drakestown section, we're in your area regularly.
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.
