Cleaning your roof seems like a daunting and dreadful task that no one wants to do often. Despite this, a clean roof has its advantages. It is essential to consider that the more often you clean your roof, the less complex the task will be. Not only will an easy job be easier to get started on and finish, but your roof will be left in better shape and can even be protected from dangers. 

How Often Should You Clean Your Roof?

Many professionals suggest that you clean your roof every 2-3 years. Some roofs that are subject to a lot of debris may even need a good clean every 18 months. A clean roof is less susceptible to dangers like wood rot and damaged shingles. How do these dangers occur, and how can they be prevented?

Damage: Wood Rot

Wood rot is a common danger of a dirty roof. Wood rot is dangerous because of the following reasons:

  • It could have a hidden leak
  • Mold might grow
  • Rodents can chew through rotten wood easily
  • It can be challenging to tell if there is an issue

Moss is a common problem that causes wood to rot because of the moisture within it. It typically grows in wet, shaded areas, which leaves the exposed wood vulnerable to decay. Fortunately, the color of moss makes it easy to spot, which can help homeowners determine when it is time for a roof cleaning.  

Damage: Shingles

A number of things can cause shingle damage. Moss, algae, and lichens are problems that occur when you do not clean your roof correctly. Algae can essentially dissolve shingles and overheat them. Lichens are known to create divots, thus ruining shingles. Moss makes shingles curl and can cause freezing damage in the colder months. Each of these factors gives your roof a much shorter life span. 


The prevention of wood rot and shingle damage on your home’s roof requires cleaning it on a sensible schedule. However, there are also other factors that can help to prevent these issues. 

  1. Clean your gutters regularly.
  2. Trim any trees near the roof.
  3. Clear off any and all debris.
  4. Contact a professional to check for proper airflow.
  5. Consider a roof replacement if damages have already occurred.
