Why Soft Washing Is the Best Choice for Roof & Siding Care

What You Don’t Know About Pressure Washing Could Cost You

Not All Cleaning Is Created Equal

When it comes to exterior cleaning, more pressure isn’t always better. In fact, using high pressure on certain surfaces can cause permanent damage.

That’s where soft washing comes in. At Banner & Shield, we specialize in using the right method for the right material—and soft washing is our go-to for delicate exteriors like siding and roofs.


What Is Soft Washing?

Soft washing is a low-pressure cleaning method that uses eco-friendly, biodegradable solutions to break down mold, mildew, algae, dirt, and grime at the source.

Unlike pressure washing—which blasts away buildup with sheer force—soft washing relies on safe detergents and a controlled rinse to clean without damage.


Surfaces That Should Never Be Pressure Washed

Pressure washing may be effective on concrete or brick, but it’s too aggressive for many exterior materials. These surfaces should be soft washed instead:

  • Asphalt shingle roofs (can tear or loosen shingles)

  • Vinyl siding (can crack or warp)

  • Stucco (can chip or crumble)

  • Wood decks and fences (can splinter or strip sealant)

  • Screens and windows (can shatter or bend frames)

Soft washing ensures your surfaces are cleaned thoroughly—without compromising their structural integrity.

 

Before & After: The Soft Wash Difference

Imagine your roof, dull with years of grime and black streaks, restored to a like-new finish. Or your siding was brought back to its original color without a trace of algae.

Soft washing delivers visible transformations that not only improve curb appeal but also extend the life of your materials.

 

What Chemicals Are Used—and Are They Safe?


Banner & Shield uses professional-grade, biodegradable detergents specifically formulated for exterior surfaces. Our solutions:

  • Kill mold and mildew at the root

  • Break down organic growth without bleach-heavy residue

  • Rinse clean without harming landscaping

  • Meet environmental and local safety standards

Your family, pets, and plants stay safe—and your surfaces stay protected.


How Often Should You Soft Wash?

To maintain a clean, healthy exterior and prevent buildup, we recommend:

  • Every 12–18 months for roofs in high-humidity areas

  • Annually for siding or fencing

  • After heavy pollen seasons or visible buildup

  • Pre-listing cleanups for real estate curb appeal


Routine soft washing helps prevent staining, pest attraction, and moisture-related damage before it starts.
