Alternatives to Roof Cleaners

If you want to clean your roof but do not want to use roof cleaners for various reasons, here are some of the best alternatives to those devices!

Bleach and Water

The combination of bleach and water is a noteworthy alternative for REMOVING DIRT from your roofs, like algae and mold, especially roof shingles.

To use this as a roof cleaner, you mix the two and put it in a container or a spray. Then use the mixture on the roof and clean from there!

However, BE CAREFUL around your house.

This mixture is bad for plants and aquatic life. It contains harsh chemicals that can seriously harm the environment around you.

To be safe, cover your plants securely and be sure that you spray properly so that none of the mixtures will drip to your ponds.

Citrus Acid

Like bleach, you can mix citrus acid with water to make an effective alternative to roof cleaners.

Use a spray and spray the mixture on your roof.

Please wait for a few minutes, then rinse it off afterward! You can remove the dirt on your roof with much more ease than cleaning the roof without this mixture.

Things to Consider When Choosing a Roof Cleaner

When choosing a product amongst its competition, you want to know the different factors that make them stand out from one another.

The same goes for roof cleaners; some things lead to purchasing a specific product.

Here are the ESSENTIAL things to consider when buying the RIGHT roof cleaner!

Composition of your Roof

The best cleaning tips for roof cleaning usually involve completely understanding what you are cleaning.

Before buying a roof cleaner, you have to be FULLY AWARE of the condition of your roof.

What’s the type of roof you have? What’s the size of your roof? Is it made of rubber or metal?

There are many factors to consider when buying a roof cleaner for your roof.

You have to know the composition of your roof to have an effective roof cleaning process! Other roof cleaners may damage your roof even more than you want to.

The Dirt That Covers Your Roof

The most common types of dirt that cover the majority of roofs are mold, mildew, and algae. However, other types of dirt can cover your roofs, like dust, moss, and others.

It is ESSENTIAL to know what dirt covers your roof because many roof cleaners only work against specific dirt.

For example, the RMR-86 Instant Mold and Mildew Stain Remover is great against mold and mildew but not good against algae.

If your roof is covered in algae, the RMR-86 is NOT the roof cleaner for you to buy.

Weather Condition in Your Place

Many roof cleaners will prove ineffective if they are washed away by RAIN.

If you want your roof cleaner to be at its most operational, you should apply it if your place will be dry for at least 12 hours for the substance to fully clean the roof.

The rain will remove the roof cleaning solutions on your roof, make space for the water from the rain, combined with environmental factors and produce dirt like algae.

DO NOT use your roof cleaner if you’re expecting rain in your place.

Ease of Use

When choosing the best roof cleaner, you also have to consider its ease of use!

The best roof cleaner out there may not work for you because you do not have to luxury that product is easy to use, especially if you are a first-timer getting into the roof cleaning process.

The ease of use in roof cleaners are divided into THREE CATEGORIES:

Spray and Forget

The spray and forget method refers to SPRAYING the roof cleaning solution to your roof and FORGETTING about them.

The substance will be activated by the wind or by the rain.

As the name implies, you spray the roof cleaning solution to your roof, especially where the dirty places are, then let it do its work!

There is no need to worry about your roof if you sprayed at the right places!

Wet and Forget

Like the spray and forget method, you leave the roof with the roof cleaning solution and forget about it.

This time, it involves POURING or BRUSHING the roof with the roof cleaning solution.

You pour or brush your roof with the cleaning substances, and once applied, you can leave it as it is and let nature do its work!

These substances can either be diluted or not as directed.

Apply and Scrub

This method is the most common way of removing dirt off your roof.

You apply the roof cleaning solution to your roof and scrub along with that substance to clean the dirt off your roof.

It is a GREAT idea to use a scrubbing material that complements the material you are scrubbing on.

Scrubbing dirt using metal on a glass material can destroy the glass material.

So be aware of that!

Frequently Asked Questions (FAQs)

Here are some of the most FAQs regarding the roof cleaner topic.

Several factors need to be considered when doing roof cleaning, so hopefully, this section will clear some things up!

How Often Should the Maintenance of the Roofs Be?

You should clean your roof at least ONCE A YEAR. Roof wash MUST NOT be done consistently!

However, that is only the general rule. Your roof can be cleaned more than once a year if you notice dirt again on the roof.

Another reason to clean it more than once a year is how proper the cleaning process was. If the roof is not properly cleaned, it may require more cleaning maintenance!

In short, maintaining your roofs should usually be done every year, but if you feel like you did not clean your roof correctly or if it gets dirty quickly, then maintain it as you wish!

Are Biodegradable Ingredients in Roof Cleaners Safe for Plants and Animals?

Roof cleaning products that utilize biodegradable ingredients are safe for plants! However, they are dangerous to animals.

It is not to say that ALL roof cleaners with biodegradable ingredients are dangerous, but it is better to be safe than sorry.

It is ADVISABLE that if you are going to use a roof cleaner, make sure your pets or any animal within your vicinity are at a safe distance from the substance. However, if those pesky squirrels are still in your roof maybe spraying them wouldn’t hurt. LOL

Do I Need Any Equipment When Roof Cleaning?

Let’s be real, any fool can learn how to clean a roof.

I would not suggest using any hard items that may increase the loss of granules.

Just make sure you have a hose that can reach the ridge vent and maybe a soft brush for the hardest stains.

Best Budget: Mold Armor E-Z House Wash
