Black streaks on a Rhode Island roof are algae, mold and mildew, not dirt, and they can be removed without replacing the roof. South County Soft Wash cleans asphalt shingle roofs with a low-pressure soft wash that kills the growth at the root, so the roof stays clean longer than it would after pressure washing.

Safe Soft Wash Roof Cleaning


Many homeowners make the costly mistake of thinking roof replacement is the only option to rid their home of any ugly, stained roof. Let us put our Soft Wash Roof Cleaning service to work for you and your home. We'll make your existing roof look like new for a fraction of roof replacement cost!

What's Eating Your Roof? Is Your Roof Covered In Black Streaks?


That isn't dirt on your roof - it's actually bacteria, algae and mold taking root on your home!

It's true, your roof actually isn’t dirty at all - but it is under attack! It's under attack from organisms like bacteria, algae, mold, and mildew that spread across your roof shingles and negatively impact your home’s beauty and property value. These organisms not only look awful, but they are also eating the limestone in your shingles, causing your roof to prematurely deteriorate and retain heat. Simply put, a black stained and streaked roof is costing you your hard earned money! See here for information about South County Soft Wash

We use a proven safe & effective Soft Wash Roof Cleaning method because standard pressure washing only attacks the stains at the surface. Pressure washing may remove the stains, but the roots remain, allowing the growth of bacteria, algae, mold and mildew to return all too easily. Our Soft Wash Roof Cleaning method completely eliminates these unsightly organisms at their source - meaning you can enjoy new looking roof for a longer period of time!

Pressure washing should NEVER be used to clean your roof! Many homeowners in the Rhode Island area have found out the hard way that standard pressure washing and roof shingles do not mix! The resulting shingle damage and water forced under their roof decking required expensive repairs to fix. This is another important reason you should only have our Soft Wash method used to remove those unsightly roof stains - Soft Washing poses zero risk of damage to your roof!

Why Not Pressure Wash a Roof?

High pressure can strip the granules off asphalt shingles, force water under them and shorten the life of the roof. It also only removes the stain at the surface, so the growth comes back quickly. Soft washing uses low pressure and a cleaning solution that kills the algae, mold and mildew where they grow.

How Does Soft Wash Roof Cleaning Work?

  1. We look at the roof and agree on what will be cleaned.
  2. We apply the cleaning solution at low pressure. Nobody blasts the shingles.
  3. The solution kills the algae, mold and mildew and breaks down the black streaks.
  4. We rinse the roof and the areas around the house.

Signs Your Roof Needs Cleaning

  • Black or dark streaks running down the shingles, usually on the north-facing side.
  • Green moss or lichen spots.
  • A roof that looks older than it is, or is uneven in color.
  • Organic growth spreading onto gutters and trim.

Frequently Asked Questions

Is soft washing safe for my roof?

Yes. Soft washing uses low pressure, so it does not strip shingle granules or force water under the shingles the way a pressure washer can.

How long does a roof cleaning last?

Because soft washing kills the growth instead of only removing the surface stain, results last much longer than pressure washing. How long depends on shade, trees and moisture around the house.

Do I have to replace a stained roof?

Usually not. Many homeowners think a streaked roof needs replacing when it only needs the algae and mold removed.
