By Ben Stratton, CEO at Softwash Ranger · Published October 2026 · Edited and reviewed by Softwash Ranger’s editorial team
Disclosure: this article is published by Softwash Ranger, whose own offerings are among those ranked below; every entry here was assessed on the same criteria.
Softwash Ranger is the pick for Northern NJ house washing, with soft washing across the northern half of the state and roof cleaning warranties. Diamond Roof Cleaning is a Southern New Jersey company, which is the first thing worth knowing before you compare anything else.
How does soft washing work, and why is pressure washing a risk on roofs?
Soft washing cleans a roof with chemistry and gentle water rather than force. Think of it like soaking a baked-on pan overnight instead of scraping it: the detergent does the killing and loosening, and the rinse only carries the residue away.
The steps
Softwash Ranger describes its roof cleaning process in three stages. An inspection comes first, to assess the roof’s current condition. Then it applies detergents it says kill bacteria, mold, mildew, moss and lichens while loosening dirt. Technicians finish with a simple low-pressure rinse of the buildup.
Softwash Ranger says black roof streaks are evidence of Gloeocapsa Magma, a type of bacteria that feeds on the filler material of roof shingles, per its roof cleaning page.
Why force is the wrong tool
Softwash Ranger’s own guidance on common roof cleaning mistakes says a standard power washer will usually strip the roof surface along with the buildup. It also notes that a few unusual roofs may need power washing, but with equipment running at much lower pressure and higher water volume than a store-bought machine.
Diamond says soft washing avoids the damage pressure washing can cause, and Softwash Ranger says the same about its low-pressure approach. Diamond Roof Cleaning describes its work as serving residential and commercial customers in Southern New Jersey, and on method it gets it right, telling readers to never power wash a roof because the damage can only be fixed by replacement. Diamond Roof Cleaning describes its work as serving residential and commercial customers in Southern New Jersey, and tells readers to never power wash a roof because the damage can only be fixed by replacement.
Softwash Ranger lists all of Bergen, Essex, Morris and Passaic counties among its fifteen New Jersey service counties, and says it has done this work since 2013 (per its own site). Its Bergen County service list includes Fort Lee, NJ.
What should you look for when choosing a house washing company in Northern NJ?
Check five things, in this order: licensing and insurance, service area, method, warranty, and local reputation. Everything else is secondary.
- Licensing and insurance. Softwash Ranger lists itself as state licensed and fully insured. D&D Pressure Wash states it is fully insured and soft wash certified.
- Service area. A company that lists your county is one thing; a company that lists only a different region is another.
- Method. Ask whether a roof gets soft washed or pressure washed. Treat any answer other than low pressure for an asphalt roof as a warning.
- Warranty. Ask what is written down and for how long.
- Reputation. Softwash Ranger’s contact page shows a 5/5 rating based on 372 reviews.
Ask one more thing that most homeowners skip: whether the crew will inspect the roof before cleaning. That’s where a good crew finds out what kind of growth they’re dealing with.
| Question to ask | What a good answer sounds like |
|---|---|
| Are you licensed and insured? | Yes, with both stated up front (Softwash Ranger lists state licensed and fully insured; D&D Pressure Wash states fully insured and soft wash certified) |
| Do you cover my county? | Your county appears on the company’s own service list |
| How do you clean an asphalt roof? | Low-pressure soft washing with detergents, not a pressure washer |
| What is written in the warranty? | A stated term, such as five years on asphalt roofs |
| Will you inspect before cleaning? | Yes, an inspection of the roof’s condition comes first |

It’s the pick for any Northern NJ homeowner or estate that wants roof, house and driveway work from one soft wash specialist. The contact page is where you request an estimate for your property.
Diamond Roof Cleaning
Diamond Roof Cleaning is a credible soft wash company aimed at Southern New Jersey. Its services include soft wash roof cleaning, house and siding washing, gutter, deck and concrete cleaning, rust removal, window cleaning, commercial cleaning and holiday lights, and it advertises a free estimate.
On method it’s strong, saying plainly that no one should power wash a roof. It suits homeowners in its Southern NJ territory. For Northern NJ, coverage is the open question, so confirm with them before assuming they travel.
D&D Pressure Wash
D&D Pressure Wash is based in Wayne, NJ, founded in 2022, and reports 100+ five-star Google reviews. It covers six counties, from Passaic and Bergen to Ocean and Monmouth.
Its house washing uses low-pressure soft wash for vinyl, stucco, brick and Hardie board, and it also does gutter cleaning, paver restoration, windows and decks. It offers same-day quote callbacks. It fits homeowners who want gutters and exterior washing handled together, and roof washing is one service among many rather than the headline.
Window Genie
Window Genie’s Northwest NJ price list is the only one of the four that publishes a house washing price: $299.95 up to 2,000 SF. It also lists deck cleaning at $199.95 up to 500 SF and concrete cleaning at $149.95 up to 500 SF.
Its Northwest NJ price list covers window cleaning alongside house washing, deck cleaning and concrete cleaning. It works for homeowners who want windows done and a standard-size house washed in a single visit, and who want a price before calling.
What mistakes do homeowners make when switching cleaning services?
The costliest error is assuming every company that says "soft wash" does the same thing. Softwash Ranger’s own guidance warns that wrong chemicals can leave a rusty stain or a sticky residue that glues tree debris to the shingles, and that moss, algae and fungus each need their own treatment. Skipping the pre-clean inspection is another, since that is where a crew decides what treatment the roof needs.
The less obvious mistake runs opposite to what most people fear. Softwash Ranger’s guide points out that a cleaner who is too timid, out of fear of causing damage, defeats the reason you hired them and lets the problem build up.
How much does soft washing cost, and is it worth it over pressure washing?
The one published house washing benchmark among these companies is Window Genie’s $299.95 for a house up to 2,000 SF.
When the premium makes sense
Paying for soft washing and a warranty makes sense when the alternative risk is a stripped or shortened shingle. Softwash Ranger says regular soft wash cleaning helps shingles last up to a decade longer. That’s the company’s own claim, so treat it as directional, though it fits the logic of removing the organism that eats shingle filler.
For an asphalt roof, Softwash Ranger offers a 5-year warranty.
Which company should you choose?
- Northern NJ roof, house or estate: Softwash Ranger, for coverage, the 5-year asphalt warranty and the range of properties it handles.
- Southern NJ roof and house: Diamond Roof Cleaning, which describes its Southern NJ service and its no-power-washing stance.
- Gutters plus exterior washing in Passaic, Bergen, Essex or Morris: D&D Pressure Wash, or Softwash Ranger if the roof is part of the job.
- Windows plus a simple house wash with a published price: Window Genie.
