How Difficult Is It To Clean A Roof?

When doing a roof cleaning, the goal is to eradicate any algae or moss that has grown on the surface. Moss and algae spores can be killed with chlorine bleach, the same stuff you use to whiten clothes or scrub the toilet. 

To clean a roof, the ARMA suggests mixing bleach and water in a 1:1 ratio. They also warn against using a power washer on asphalt shingles since the force of the water can damage them.

The bleach solution should rest on the roof for up to 20 minutes before being washed with clean water. Any leftover algae on the roof should be washed away by a few rainstorms. If there is any moss on your roof after cleaning it, they may use a leaf blower to get it off.

The Advantages And Disadvantages Are As Follows:

Roof cleaning can help to extend the life of shingles or other roofing materials by removing debris. The Asphalt Shingle Manufacturers Association (ARMA) claims algae aren’t detrimental to asphalt shingles, but moss is.

Moss can cause the shingles’ edges to curl upward, increasing the likelihood that they will be blown off the roof in high winds. Even though algae will not hurt your shingles, it might have a detrimental impact on their appearance and functionality. This is especially true if your home has an excellent or reflecting roof.

The reflecting characteristics of the roof will be harmed by black algae growth. Roof cleaning has the disadvantage of being time-consuming. To destroy the algae or moss, you may have to climb up on your roof and spray it with water or use a chemical cleaning. 

Thank goodness the National Roofing Contractors Association says that cleaning your roof is not something you should attempt to do on your own. Leave the roof cleaning to the experts. Cleaning your roof might also damage any nearby plants because the cleaning agent (often bleach) can defoliate the leaves and stems of the plants. Before washing your roof, any adjacent plants should be watered and covered by your roofing professional to protect them from chemical exposure.
