The roof of our home or camper is the most overlooked place when it comes to regular cleaning and maintenance. That’s because we may not spend as much time in this part and therefore, it’s an out-of-sight, out-of-mind situation.
As the roof is the one part of the house or RV that is directly under the elements throughout the year, it tends to form layers of dust, dirt, and grime that lead to the formation of ugly mold and lichens.
These are stubborn growths and can leave dull green marks on the roof tiles and shingles if left unattended for long.
To make things less complicated, many solutions can be used to clean the roof. Various types of these cleaners are available in the market.
We have conducted some in-depth research to bring to you the best roof cleaner to suit your needs. Go through this post to know all about it!
What To Look For Before Buying Roof Cleaning Products?
There are various types of roof cleaning products and before you decide on which one is right for you, you may like to consider the following factors that are outlined based on roof cleaning product reviews.
Have you checked what the material is on your roof?
Depending on the roof material, you should select the roof shampoo products. Cleaners with chemical components are usually harsh and will not harm the roof if it’s made from stones, metal, or other tough stuff.
But, if you have asphalt or rubber as part of the roof construction, then choose a cleaning agent that is less harsh and therefore, less damaging to these materials.
You could choose from a range of either a chemical or a non-chemical formula. With the latter kind, you are not harming the environment as there are no chemical components like chlorine or any type of acid. With the former kind, you need to be very careful while using it so that you don’t harm yourself.
However, chemicals are more effective on stains that have become tough to get rid of.
If you are conscious about how your actions can impact the environment, then it’s better to choose an eco-friendly and biodegradable roof cleaner.
Some roof cleaning items can be sprayed and left on to do its work, while others need to be scrubbed. Then there are others that not only require spraying but also need to be rinsed out. Depending on the workload you can take, choose a cleaner to make life easier for you.
How well a roof cleaning solution works and how fast it does so are major considerations. A non-chemical agent will take more time to clean out the roof as it is milder than its chemical counterpart.
If you opt for reputable brands, the effectiveness will be seen immediately, as opposed to cheaper alternatives. Those cleaners that need rinsing also show instant results. Any good brand will stay on the surface and protect your roof from the growth of mold, mildew, and algae.
Depending on the surface area of the roof, you should choose a cleaner with a clear indication on the label as to its quantity and coverage. The ones that need dilution will cover more surface area.

Different Types Of Roof Cleaners Available On The Market
There are various types of roof cleaners available and depending on your needs and the roof material, you can choose one. A read-through of the following will make you better informed on the different kinds and their functions.
Chlorine bleach or sodium hypochlorite is the main component of a beach-based roof cleaner. Those meant for extra-tough work also may contain trisodium phosphate.
These chemicals make such cleaners quite harsh. As a result, you only need to spray them on the roof and wait for it to dry. After drying, you can reapply a few times more until you get the desired results.
Just be careful when applying these. They can cause harm to your plants and trees so apply with caution. The strong smell of bleach is not too pleasant. It’s recommended to keep away pets and children from the bleach-treated roof for as much as up to 72 hours.
Besides bleach, there are other chemical compounds used to make roof cleaning products. Trisodium phosphate and copper sulfate are some of the other options.
For metal roofing, a chemical emulsifier containing ammonia is a good option. They work effectively to remove dirt, grease, and grime from the metal parts of the roof.
Be careful when using these products as these can harm your grass and other plants if they come in contact. Also, double-check before using as these chemicals can reduce the life of your roof shingles, leading to replacement long before the due time.
Many users opt for eco-friendly or green cleaning agents for the roof. You don’t need to practice caution while using them plus they are not harmful to the environment. They work effectively to remove moss, algae, mildew, and the stains left by these.
The application of such cleaners does not require any elbow grease except for some light scrubbing. As these products are oxygen-based, they provide the same effectiveness as cleaners with harsh chemicals. The plus point is that they don’t harm the environment or the roofing material.
Safe for use in households with pets, children, and greenery, an eco-friendly roof cleaner solution is also compatible with all types of roofing materials.
A pressure washer using high pressure is used to clean the roof with water. Sometimes a chemical cleaner may be mixed with the water. The force with which the water is projected helps to clean the roof tiles of mold and mildew as well as the stains.
However, this method of cleaning is not recommended as the force can damage your roof, especially if the roof has shingles. Another downside is that pressure cleaning mostly uses water which does not do anything to address the root cause of moss and algae.

Frequently Asked Questions (FAQ).
1. Why Are Bio-Degradable Roof Cleaners Preferred?
Answer: As bio-degradable roof cleaning agents are safe for the environment as well as pets and humans, they are preferred by many. However, their action is slow and they may not be as effective as acid- or bleach-based alternatives.
If you exercise enough precaution in terms of using protective clothing and ensuring that your plants are covered or your children and pets maintain a distance, then you can use a traditional roof cleaner without causing harm.
2. Why Do I Need A Specific Roof Cleaning Chemical For Specific Materials?
Answer:All materials will not clean equally well with just any type of a roof cleaning chemical. Various surface materials respond in different ways to the same cleaning agent. For example, if your roof has wooden parts, it’s not okay to apply a chemical that contains acids, bleach, or salts as it will cause fading.
For rubber roofing material, you need a non-caustic cleaner, since you wouldn't want the rubber to be corroded by an abrasive cleaner. However, for tougher materials like cement, stones, metals, or bricks, you need a heavy-duty cleaner that will be tough on the black stains and oxidation.
3. Can A Single Roof Cleaner Be Used With And Without Dilution?
Answer:There are some cleaners that work both in a diluted and non-diluted form. Such products are, therefore, suitable for both normal stains and more long-standing and stubborn stains.
To address the former type of stains, you can use the diluted format while for the tough stains, you can use the product without diluting it with water.
4. How Can Mold Cause Damage To The Roof?
Answer:Mold, mildew, fungus, algae, and lichen are all biological growths that take root on your roof materials. Not only do they leave stains on your roof, but they also grow into the surface material, causing them to weaken over time.
If you do not remove these biological substances, they will harm the materials and cause premature deterioration.
5. What Equipment Do I Need For Cleaning The Roof?
Answer: If you are using a brand of roof shampoo product that doesn’t require any post-application action like scrubbing or rinsing, then you don’t need any equipment except a garden or a tank sprayer. However, if your chosen product already comes with a sprayer, you won’t need to arrange that either.
However, there are products are needed for scrubbing or mopping or rinsing after application. In that case, you will need a long garden hose for rinsing thoroughly, a bristle brush for scrubbing, or a sponge mop for mopping.
You may also need a clean or microfiber cloth for those products that require wiping.
If you have chosen a chemical-based roof cleaner solution, you will need rubber gloves to protect your hand and a mask and goggles to protect your face.
6. How Can I Protect My Plants When Using A Roof Cleaner?
Answer: It is advised to spray water before and after you apply a roof cleaning chemical. Especially in the case of chemical cleaners, you should take extra caution with your garden. It’s better to opt for a biodegradable roof cleaner product that contains no harsh chemicals so as not to harm your plants.
Taking care of your roof is as important as maintaining the rest of your home or your RV. You will continue to enjoy the long-term benefits if you keep an eye on stains and biological substances growing on the roof. You can pre-empt the damage they can cause by using the best roof cleaner regularly.
So, you have a choice between non-chemical roof cleaners that are safe for the environment and the chemical ones that are more effective but not eco-friendly. Depending on the strength of the stains and the surface material, choose one wisely.
Always exercise caution when using these cleaning solutions and read the package label carefully. You can save a lot of money by maintaining a good condition of your roof before they get taken over by fungi and mold and are weakened.
