When and How Roof Cleaning Should Be Done?

Posted on January 30th, 2019 by Applied Roofing Services

Cleaning the roof is important, but many people simply don’t have time or can’t remember to put it on their To Do List. Remembering to do it once every two or three years should be sufficient as long as you remember to inspect your shingles every year to prevent any real damage from occurring.

Roof Cleaning Tips

Remove Loose Debris

Before washing or rinsing your roof, remove any loose debris. This prevents it from sliding down and clogging the gutters. It will also prevent stains from appearing on the shingles. Large sticks can tear or damage shingles, so making sure they are removed as soon as they are noticed is the key to preventing damage to the roof and leaks inside the home.

Clean the Gutters

Always make sure the gutters are thoroughly cleaned and water is allowed to drain away smoothly. This will prevent moisture from seeping under the shingles and roofing materials. Clean the gutters at least once a year. This will allow for proper drainage and will also make your home look nice and well maintained.

Wash the Roof Carefully

Power washing a roof can damage the shingles. When you wash your roof, make sure the sprayer is on the lightest pressure setting possible as to not lift or damage the shingles. Mix 1 cup bleach, 1 cup of laundry detergent and a gallon of water in a garden sprayer. Start at the bottom and spray upwards, covering as much of the roof as possible. Use the power washer or garden hose to gently wash the soap away. This will help to control mold and prevent it from growing in the creases of the shingles.

Here’s what you should know about roof cleaning.

Why is Roof Cleaning Important?

As the roofing system is a considerable investment, roof cleaning should be a priority in your home maintenance and your roof maintenance list. Some significant benefits of roof cleaning and maintenance include:

  • Keeping your family safe and comfortable inside
  • Prolonging your roofing system’s life
  • Giving your roof a fresh new look
  • Preventing pest infestations
  • Allowing bigger energy savings

What is the Best Time of the Year for Roof Cleaning?

Experts recommend performing roof cleaning and maintenance during summer months. This ensures enough sunshine on your roof, making its surface dry and safer to walk on. Since stepping on the roof is very risky, having a dry surface prevents slipping and injuries.

How Often Should You Have Your Roof Cleaned?

The frequency of roof cleaning depends on various factors that affect the state of your roof. Usually, you require roof cleaning once a year. However, a newly installed roofing will need less cleaning, perhaps every two years.

When Do You Need to Clean Your Roof?

You should visually inspect your roof on a regular basis to know whether your roof needs some maintenance. If you notice the growth of moss, algae, leaves, branches, or other debris, you should hire professionals to handle the cleaning job really well.

How Long Does It Take to Clean Your Roof?

You can expect roof cleaning to take some time. Roof cleaning is an activity that may sometimes need a few days for achieving satisfactory results. It involves a gradual extermination process of the contaminants as well as power washing to remove the filth.


Maintaining a clean roof will go a long way in extending the life of your roof by preventing decay which may demand costly repairs or even a complete roof replacement. The safest and best approach to cleaning your roof is to hire a qualified roofing contractor who specializes in roof cleaning and maintenance.
