How To Clean an Asphalt Roof

Author: Rebekah Pierce

Asphalt roofs are a popular choice for homeowners because of their durability and low cost.  While asphalt roofs require little maintenance, they do need to be cleaned occasionally to remove built-up debris and stains. This guide will show you how to clean an asphalt roof using common household products.  Let’s get started!

How to Clean an Asphalt Roof: Tips for Success

Over time, asphalt roofs can become stained and discoloured. Luckily, with a little elbow grease and the right cleaning products, you can restore your roof to its original glory.  With these tips, you’ll have your asphalt roof looking good as new in no time!

Understand Which Chemicals to Use

While it may be tempting to reach for a power washer to blast away the dirt, this can actually damage your roof. Instead, it is important to understand which cleaning chemicals are safe to use on an asphalt roof.  A gentle solution of soap and water is usually all that is needed to remove most superficial stains. For more stubborn dirt, you can use a mixture of bleach and water. There are also specialised chemicals you can use that are made specifically for asphalt roofs. However, it is important to avoid using any cleaners that contain abrasives or harsh chemicals, as these can strip away the protective layer of asphalt.

Find the Right Weather

The best time to clean an asphalt roof is in the spring, when the weather is warm and dry. This will help to loosen any dirt or debris that has built up over the winter months. Avoid cleaning the roof in cold or wet weather, as this can damage the asphalt. If you can’t wait for the perfect spring day, you can still clean your roof in less-than-ideal conditions by using a soft-bristle brush instead of a pressure washer. Just be sure to avoid scraping or scrubbing too forcefully, as this could damage the asphalt.

Take Safety Precautions

Before you begin cleaning your asphalt roof, there are a few safety precautions you should take. First, make sure the area around the house is clear of any debris that could blow onto the roof and damage the shingles.  Second, have someone help you with the ladder to ensure that it is sturdy and secure.  Finally, wear gloves and a respirator to protect yourself from the fumes of the cleaning products. With these safety measures in place, you can clean your asphalt roof without worry.

Pick Up the Proper Tools

Cleaning an asphalt roof is a relatively simple process as long as you have the right tools. First, you will need a soft-bristled brush to loosen any stubborn dirt and debris. Next, you will need a hose with a high-pressure nozzle to wash away any remaining dirt and grime.  Finally, you will need a mild soap or detergent to break down any tough stains. With these three simple tools, you will be able to clean your asphalt roof and restore it to its original beauty.

Spray the Roof with Water Before Applying Cleaning Solution

One important aspect of cleaning an asphalt roof is to spray it down with water before applying any cleaning solution. This will help to cool the roof and prevent the cleaner from drying out too quickly. After spraying the roof with water, apply the cleaning solution and wait for 20 minutes before rinsing it off.

Take Steps to Prevent the Regrowth of Mold, Algae, and Mildew

In order to clean an asphalt roof, it is important to take steps to prevent the regrowth of mold, algae, and mildew. Installing zinc or copper strips near the edge of the roof can help to prevent the growth of these organisms.  Trimming back tree branches and removing debris can also help to create a drier environment that is less conducive to their growth. In addition, ensuring adequate airflow around the roof and cleaning out gutters can also help to reduce the likelihood of mold, algae, and mildew growth.

Don’t Wait Until the Last Minute

Cleaning an asphalt roof is an important part of maintaining your home. Asphalt roofs are susceptible to a build-up of dirt, grime, and moss, which can lead to premature deterioration.  While it may be tempting to wait until the last minute to clean your roof, this is actually one of the worst things you can do. The longer you wait, the more time dirt and grime have to build up, making it more difficult to remove. In addition, waiting too long can also damage the shingles, increasing the likelihood of leaks.  If you want to keep your asphalt roof in top condition, it’s important to clean it on a regular basis. By taking care of your roof, you’ll extend its lifespan and protect your home from expensive repairs down the road. Cleaning an asphalt roof is a fairly simple process that can be completed with the right tools and knowledge. By following the steps we’ve outlined in this post, you should be able to clean your roof safely and effectively.
