Homeowner’s Guide: How to Get Stains Off the Roof

Homeowner's Guide How to Get Stains Off the Roof

A dirty roof isn’t the first thing a homeowner will notice when working on their home improvement to-do list. But it’s important to keep an eye on the roof because stains could lead to potential damage in the future.

Due to changing weather conditions, wear and tear can result in unsightly roof stains due to mildew, mold, or algae. When these stains are left untreated, they start to eat away at the shingles, which can compromise the integrity of the roof.

As a homeowner, it’s important that you know how to spot roof stains and what to do to clean the stains and prevent damage. Here is a quick start guide with an overview of what you need to know:

Different Roof Cleaning Methods

There are multiple ways you can clean roof stains, depending on the type of roof that you have and the severity of the stains. Options include:

  • Low-Pressure Roof Cleaning: The benefit of this service is that it’s a chemical-free way to remove stains. Instead of using chemicals to wash away the algae, a low-pressure rinse blasts away the damage-causing buildup. One advantage of low-pressure cleaning is that it’s the most eco-friendly and safe solution for your home and family.
  • High-Pressure Roof Cleaning: Another pressure cleaning option is using high-pressure water delivery tools. These “blast” the stains away and are more aggressive compared to low-pressure cleaning. It’s better to use low-pressure cleaning instead of high-pressure scrubbing to preserve the overall quality and durability of the roof. A power washer shouldn’t be used on a shingle roof, but it can be helpful at times for metal or tile roofs.
  • Roof Cleaning with Chemicals: If the stains are stubborn, it might be necessary to use chemical products to lift them. Professional roof cleaners sometimes recommend the use of products such as chlorine bleach, trisodium phosphate, and sodium hydroxide. With this method, the cleaning solution is sprayed on the roof stains. Then, the stains start to fade gradually.

Timing Matters: Don’t Procrastinate Roof Cleaning

The best solution for roof cleaning is to treat the stains as soon as possible. Algae, moss, and mildew are easier to remove in the beginning stages. However, as the stain progresses, it becomes more challenging to get rid of the stains, and the microorganisms can cause severe structural damage to your roof.

DIY roof cleaning can be complicated and potentially dangerous if you don’t have the proper safety equipment. If you notice stains on your roof, the most effective solution is to call a professional cleaning company for assistance. We can diagnose the problem and help you determine the ideal treatment plan to eliminate the stains and protect your roof at the same time.
