How Long Does It Take To Clean a Roof? 4 Factors and Timeline

by | Sep 21, 2021

The extreme conditions of the different seasons can wreak havoc on your roof. Rain, snow, ice, fog, and shade from trees create the perfect environment for fungi and moss to grow, while the sun’s UV rays can damage your roof’s asphalt shingles. While all this can wear away your roof, regular cleaning can help.

One of the most frequent questions homeowners in Surrey asked us that how long it takes to clean a roof. This post will give you the information you need to learn about roof cleaning and how long the process takes.

How Long Does It Take to Clean a Roof?

It often takes our professional team between two and five hours to clean a roof. However, the exact time depends on several factors, such as your roof’s size and condition.

The following factors will affect how long it will take us to clean your roof professionally.

State of Your Roof

The roof cleaning will take longer if you have a roof in poor condition or covered with debris and leaves. This is because we need the added time to clear all the debris before spraying the cleaning solution. Otherwise, the shingles will not be completely saturated and will need more applications.

The Size of Your Roof

The larger the roof, the longer the cleaning process will take. Also, the number of roofs that faces your home will play a role.

Though many homes in Surry have two roof faces, some homes have more. Cleaning such roofs will take longer because we must spray each face. In addition, since we do this from a ladder on the gutter line, we will need to move the ladder multiple times, extending the process.


Your home’s landscape is another factor affecting how long it will take to clean your roof. Before starting the roof cleaning, we must ensure that your landscaping stays safe from our cleaning solutions.

Since this process happens to be the most time-sensitive step, the more ornate your landscape, the longer the cleaning will take.

Your Roof’s Age

Your roof’s age will determine the cleaning process we use. As such, the roof’s age impacts how long the cleaning will take. For instance, we use soft wash systems when cleaning old roofs, starting the process by applying certain detergents and surfactants that seep into your roof’s pores and pits.

We then use gentle but robust and soft wash cleansers that dissolve different residues, such as dust, dirt, grit, soot, and grime. These systems apply pressure not that much stronger than that of a garden hose or leaf blower. This ensures we don’t destroy or loosen old, brittle roofing tiles or wash away the damaged granules.

Proper Roof Cleaning Is Not a DIY Job

Unlike cleaning the rest of your Surrey home, you should always leave roof cleaning to the professionals. Consider why you should opt against renting a pressure washer and tackling your roof cleaning project on your own.

It Can Be Dangerous

Trying to balance on your roof is already dangerous on its own. Imagine trying to do so while managing a powerful pressure washer as you stand on a slick, sloped surface. This activity proves not only tricky and almost impossible for the inexperienced, but it is also very risky. Falling off your roof can lead to severe injuries and, in some cases, even fatalities.

You Could Damage Shingles

Spraying your roofing shingles and tiles from below can loosen their staples and nails. This may make them more likely to lose during storms and high winds.

It Won’t Be as Effective

Thorough roof cleaning requires expertise. You need to know how to reach the debris and dirt hidden between the crevices of your roofing shingles without damaging them. Without adequate skill and experience, you will not know how to clean around vents, flashing, chimneys, and other features your roof might have.

You Do Not Have Access to the Right Tools

Professional contractors know the right equipment and tools to use for the job. For instance, we know the correct surfactant or detergent to dissolve grime and dirt without damaging your roof’s shingles and causing damage.
