Some contractors offering power washing services in NJ also offer soft washing services. Power washing uses professional power washing equipment along with pressurized water to get the best results. Soft washing relies on cleaning agents to get the job done.

Soft washing is appropriate on asphalt shingle roofs. It is also ideal for use on softer substrates like stucco, wood siding and the like.

With soft washing, chemicals loosen the dirt. Technicians then rinse it away. Soft washing services should always use cleaning agents more friendly to the environment and only in the necessary quantities. Cleaners, degreasers and disinfectants all have a role to play, depending on the surface. For example, soft washing a roof may combine sodium hypochlorite with a surfactant. The surfactant keeps the treated surface wetter longer, prolonging the cleaning action.

Uses for Soft Washing

Soft washing addresses many needs around your property, and professional cleaning protects your investment and improves your property’s overall look. Below are some of the many uses for soft washing.

Soft washing for dirt & grime

Over time, dirt and grime accumulate on residential roofs, exterior walls, eaves, driveways, decks and fences. Where does all that dirt & grime come from?

Air pollution – Particulates often settle on NJ home exteriors. Over time, they dull the once-bright colors of your siding or shingles. The EPA monitors air particulates along with other pollution indicators. Particulates are definitely an issue in the Tri-state region.

Rain – Raindrops often contain dust, dirt and soot. This phenomenon is often more pronounced in summer thunderstorms. Updrafts carry dirt from farmer’s fields high into the atmosphere. Raindrops gather dust, dirt and pollution as they fall to earth. That’s why your car is sometimes covered in dirt after rainstorms. Heavy rain often splatters garden soil on foundations and siding. If left alone, it may harden into a crusty coating that stubbornly adheres to the side of your home. These crusty accumulations may require higher pressure power washing services in NJ.

Birds, trees and more – Many of the things that attack your vehicle’s finish also impact your home. Local flora and fauna create things that accumulate on roofs, decks and drives. Bird droppings, bug residue, cobwebs and tree sap are a few examples.

Soft washing for dark streaking

Many NJ roofs have dark streaking caused by blue-green algae. Soft washing with the right cleaning agents removes dark streaks. Simultaneously, proper soft washing protects your asphalt shingles. Next time you re-roof, consider special algae-resistant shingles. They feature granules that release copper, a mineral that prevents algae formation. Consider StreakGuard shingles from Owens Corning or StainGuard Plus shingles from GAF. Chlorine beach mixtures deliver quick results. Those with oxygen bleach need time to have an effect.

A post in This Old House, notes that the web-like growth of algae and lichens traps pollen and debris. Algae contain enzymes that attack the adhesives holding the granules to the shingles. This leads to cycles of granule loss, loss of UV resistance and brittle shingles.

Soft washing for moss removal

The moss that so often grows on northern exposures and heavily shaded areas is unsightly. There are few ways to reduce your home’s curb appeal more dramatically than to let moss take over.

Many NJ residential roofs experience moss growth, particularly in heavily wooded areas. Thick moss mats can actually grow under your shingles, causing them to lift. When this happens, water infiltration may follow. This can cause rotting of sheathing and framing. Sometimes, the mats are so thick that they need manual removal followed by the use of soft washing. Brushes and pressure washing are other methods of moss removal. It is imperative that technicians are careful to avoid damage to shingles. This is where cleaning by roofing specialists is a real plus.

Soft washing for mold growth

Metal, vinyl, aluminum and latex paints with anti-fungal additives resist mold growth. Therefore, mold growth is unlikely as long as the surfaces remain clean. Keep in mind that mold spores do attach themselves to soiled and grimy surfaces. Soft washing with the right chemicals wipes away existing mold. It leaves a clean smooth surface that resists future growth of mold.

Periodic soft washing of these exterior surfaces will limit mold growth. This is particularly important when it comes to ventilated soffits. Mold on those surfaces often gets into the attic. The use of the right cleaning agents in the right concentrations is critical to success.

Settled dust is a prime breeding ground for mold, particularly in areas of high humidity. Every summer, northern New Jersey’s proximity to the Atlantic Ocean causes humid air to sweep in from the coast.
