Things to Consider Before Buying

If you want to end up choosing a cleaning solution that is guaranteed to get the job done, then you definitely need to choose the best one. Here are some of the factors that you should consider if you want to buy the best cleaning solution.

Type of Roof

When we say the type of roof, we are not referring to the shape but the material used to make the roof. Different houses have a roof made up of different kinds of material.

Now, you should know that you cannot go about and use any cleaning solution on any type of material. This is because not all materials are capable of handling a strong solution, especially ones that contain harsh chemicals.

For those types of materials such as rubber or asphalt, we will recommend getting a gentle cleaner if you want to avoid damaging it.

Ease of Application

Thankfully, most roof cleaners that are being offered in the market can be used just by diluting and spraying the solution. That being said, some of the solutions are made to be left alone, while some will require you to put in work by scrubbing or rinsing it out.

Now, we understand that not everyone enjoys the process of working on cleaning their roofs. For them, we will recommend getting a solution that can be left on and taken care of by mother nature.

Obviously, you would want to have a product that is effective in getting all the unwanted stains and biological organisms out. But, you should also understand that different products require a different amount of time to bring in effective results.

Depending on your current need, you can opt for a leave on a solution that will show results with time or for a solution that requires scrubbing or rinsing for immediate results.

Type of Cleaning Solution

You will find two main kinds of roof cleaning products – the ones that contain harsh chemicals such as acid or chlorine or the eco-friendly ones.

If you opt for a product with harsh chemicals, you will need to take precautions while handling the product for safety purposes. You will also need to make sure that the area has proper ventilation to avoid fumes from taking over and damaging the surroundings. One more thing to keep in mind will be that these solutions usually bring results immediately, so you will need to keep your eyes on the progress to avoid harming the surface.

Now, if you want an eco-friendly product, you will not have to worry about taking any precautions. You will also be able to use it freely around plants and some around pets without worrying about toxicity.

However, ecofriendly products are usually more expensive compared to harsher products. So, if you want to commit to these, you need to be ready to invest more.


Now, we always want to spend as little as possible when it comes to purchasing anything. Thankfully, most of the cleaning solutions that we have featured in our review are all within our budget range.

That being said, some of the products are a bit pricier compared to others. But, all of them come with features that justify the asking price.

Roof cleaning is something that we need to do once to highest twice a year. Thus, we will definitely want to get a product that will give us the most out of it.

If you want to get a solution that will be able to cover all of the needed areas with ease or you want a solution that can be used multiple times, then you should definitely look for a highly concentrated solution.

Highly concentrated solutions can either be diluted and increased in volume, or, the concentration is strong enough to require less amount. In this way, you will get to use the cleaning solution more than once.

Types of Roof Cleaners
