The Cost of Roof Cleaning in New Jersey

Why Avoid Pressure Washing Your Roof?

Some roof cleaning companies in New Jersey use machines resembling floor buffers, known as “surface cleaners,” attached to pressure washers. While this method delivers instant results, it can dislodge roofing granules and shorten the roof’s lifespan. Homeowners who prioritize quick results, like those preparing to sell their homes, may opt for this method. However, it is not the recommended approach and can void shingle warranties.

Roof cleaning is not a “power washing” job. Never let anyone attempt to clean your shingles with any type of device that is hooked up to any type of pressure washer.

Non-Pressure Roof Cleaning Is Best!

Non-pressure roof cleaning is the alternative method, favored by shingle manufacturers, as it doesn’t involve pressure washers. Instead, it utilizes a sodium hypochlorite-based detergent, similar to household bleach. A certified roof cleaner is trained to know the exact mixture of sodium hypochlorite, water, and surfactant to blend to achieve optimal results.

Though many people cringe at the thought of using bleach around their home, sodium hypochlorite is very biodegradable. It is made from common salt and ends up as common salt. This is why all municipalities use sodium hypochlorite to treat the tap water we all drink. This product is also used in swimming pools to inhibit the growth of algae. So it would make sense that the manufacturer of shingles suggests using this product. The main question to ask a contractor who uses this method is how they intend to protect the surrounding landscape. Most contractors using this method will cover all landscape and have a ground man who constantly waters down the surrounding area. They should also bag the gutters to collect the runoff.

This process does not produce instant results, but it ensures a longer-lasting clean, as it eliminates all living organisms on the roof. Any black staining will be removed instantly but solids like moss and lichens will die, dry out, and come off within a few rains. Though this process will not produce instant gratification, the roof will actually stay cleaner for a longer period of time since treating the whole roof will produce a 100% kill ratio on all living organisms on a roof.

While the average cost for roof cleaning in New Jersey hovers around $600, prices may vary depending on your specific needs and the size of your home. It’s essential to consider the long-term benefits, as a clean roof not only enhances your property’s appearance but also contributes to energy efficiency and higher property values.

Consider The Full Cost of Roof Cleaning

When it comes to selecting the right contractor for your roof cleaning project, price is just one piece of the puzzle. While it’s tempting to focus solely on the cost, there are other critical factors that should be part of your decision-making process. Two crucial factors to consider are insurance coverage and sales tax inclusion in the quote:

1. Insurance Coverage: Ensure the contractor has liability and workers’ compensation insurance. This protects you, shows professionalism, and offers peace of mind.

2. Sales Tax Inclusion: Contractors who include sales tax in their quotes demonstrate legitimacy, transparency, and legal compliance.

The presence of insurance coverage and the inclusion of sales tax in the quote are two key indicators of a legitimate and trustworthy contractor. Prioritizing these factors alongside the cost will help you make an informed decision, ultimately safeguarding your home and your investment in its maintenance.
