Having the right roof cleaning chemical is one thing and having the right tools to work with the chemical is another. Even with the right chemicals, you need the right applicator to do a good job. While there are large commercial roof cleaner applicators, our focus is on applicators or sprayers you can use at home on your own.

For this class of applicators, you have many options from small handheld sprayers to large back pack sprayers fitting different occasions. It’ll depend on the type of roof you have and the dirt on the roof that needs getting rid of.

When choosing the right applicator or sprayer to clean your roof with, put in mind aspects such as the size and height of the roof, the amount of cleaning agent the applicator can carry and design of the roof. These aspects dictate a lot since some types of dirt can’t be cleaned off by all applicators. Following are our top picks of applicators.

Guide: Factors & Features to consider when shopping

When in the market for a quality roof cleaning sprayer, you should consider the following aspects:

Size of the sprayer in gallons

The first thing you need to look at in choosing a sprayer is the size of the tank. For this one, you have options from half a gallon to 4 gallons or even more. For small and low roofs or small spots on the roof, a small half-gallon or 1-gallon can is enough for that. For whole roofs or large roofs with lots of dirt, you’ll need a bigger applicator.

Design of the applicator

The design of the applicator also determines whether to get it or not. There are many designs from simple handheld sprayers to large ground-based ones with long pipes going several building floors upwards. You will make a decision on these designs based on your needs such as the size of the roof, the steepness of the roof and the type of dirt you’re dealing with.

Quality of materials

You’ll be dealing with strong chemicals and will thus need quality materials that won’t break or corrode when in use. Every part of the applicator needs to have the best materials which can withstand harsh chemicals and use in the sun. They should also have high quality Viton seals and gaskets to prevent chemicals from leaking and burning the user.

Other features

Other features and aspects to consider include other roles you can put the sprayer to with some usable in the garden and the lawn as well.

With these features in mind, you can easily find the right roof cleaning sprayer for your type of roof. If your roof cleaning procedure is too complex and requires climbing to the roof, you should follow the right safety precautions or get an expert to do it for you.
