Shingle Roof Cleaning 101: How to Clean Roof Shingles

Maintaining your roof clean not only makes your property look appealing, but it also allows you to maintain the life of your home. Dust, lichens, molds, and debris may accumulate over the years and cause runoffs, staining, and rotting of the shingles.

When cleaning a shingle roof, we ensure that your roof doesn’t just look great, but that it is also durable and solid in order to keep your house appealing and dependable for many years to come. 

In this article, we will discuss the safest ways to clean roof shingles, including the products needed and tips on how to stay safe during the process.

What Is the Best Way to Clean a Roof

Roof cleaning can also be performed in a variety of ways, varying with the shingle type and the infestation level of the algae or moss. Asphalt shingles are easier to clean with chemicals, intermediate detergents, or even water. To avoid damage to the surface, slate, tile, and wood shingles should be worked with some gentler means.

Most roofs can be washed with soft washing, which does not damage the surfaces on the roof, instead removing dirt, algae, and moss. Thus, avoid using high-pressure washers, which can literally wash off the granules of shingles and cause leakage. 

It is advised that you only apply an appropriate roof shingle cleaner or suitable shingle roof cleaning products to achieve a good result.

How to Clean Asphalt Roofing

However, proper cleaning of asphalt shingles will ensure that your roof looks good and doesn’t have any ugly materials aggregate in the long run. You should make the following related actions:

1. Remove Loose Debris

Dust greatly makes the cleaning solution more effective. We recommend sweeping or blowing before vacuuming, as it makes the job a lot easier.

2. Check for Roof Damage

Once the debris has been cleaned off, inspect your shingles for cracks between them or loose shingles, or worn patches of roofing. As stagnancy develops in tight spaces or areas not easy to access, these are also addressed before cleaning is performed.

3. Protect Surrounding Plants

Plastic sheets are used to cover objects around plants and landscapes. Doing this will ensure that the cleaning solution does not kill flowers, shrubs, or grass.

4. Make the Solution

Select a shingle cleaner that is designed to be applied to asphalt shingles or combine water with a low-sulfur detergent. A light formula cleans your shingles and also removes dirt, moss, or algae.

5. Apply the Cleaner

You could use a pump sprayer to apply an even solution. Use a sprayer or hire a professional to ensure even coverage.

6. Let the Cleaner Work

Leave the solution to break through dirt, moss, or algae for 15-20 minutes. This makes scrubbing easier and more effective.

7. Gently Scrub 

To treat the stiff moss or stain, apply the soft-bristle brush to rub against the surface. Do not scrub too strongly, which can destroy the shingles.

8. Rinse Thoroughly

Wash the roof surface with a garden hose on low pressure. This removes the cleaner and debris without loosening the shingles.

9. Inspect and Repeat if Needed

Look for any trace dirt or moss. Reapplying to difficult areas and rinsing again may be necessary for a complete clean.

10. Clean Gutters and Downspouts

Finally, you’ve to wash out your gutters and downspouts to remove debris. This helps the proper drainage of water and prevents possible buildup of roofing in the future.

Cleaning Roof Shingles with Bleach

Chlorine bleach or pool shock is an effective shingle algae killer.

  • Solution: Add one pound of pool shock for every gallon of water
  • Apply: spray the affected zones with the algae and allow the solution to rest for 20-30 minutes.
  • Rinse: This should be done softly using a garden hose by laying down pieces of plastic material to absorb the water and keep the plants and grass dry.
  • Safety Precautions: Wear protective coveralls that cover hands, eyes, goggles, and nose and mouth completely. You should always consider the instructions of the manufacturer. Similarly, before applying all over the roof, be sure to apply on a small area to test.

Another way you can clean the gutters is by pouring 1 cup of pool shock per gallon of water and then soaking it at a time of 15-20 minutes, and running it through the gutters. Other non-toxic bleaches are oxygen bleach, chlorine bleach, or products with peroxide as the cleaning agent.

Cleaning Roofs with Uncommon Shingles

Not all roofs are constructed from asphalt. Different shingles have different needs for care to remain clean and undamaged.

1. Clay Tiles 

Add mild dish soap combined with water, and wipe the surface off. Rinse thoroughly with water. Do not apply harsh chemical products, which may destroy the tiles.

2. Slate Tiles

Slate tiles are extremely low maintenance and can be washed only with water and a mild detergent, and a soft brush. This stone is brittle, so careful handling of the stone is recommended.

3. Wood Shingles

Clean stains with 3 parts water for every one part bleach. Or clean it lightly using a soft brush. Never power wash, which will undercut and destroy the wood.

4. Cedar Shakes

Wash with water and wood-safe cleaner. It is easy to scrub and resists algae growth. Don’t use bleach; this will destroy the porous wood.

Roof Cleaning Safety Tips

Cleaning your roof maintains your roof in a good state and in a nice condition, but it is risky if you are not cautious. Wearing safety measures protects you from falling, injury, and chemicals. Simple and safe advice that will ensure the roof cleaning task is a success without any incidents.

  • No Walking on Wet Roofs: Shingles that are covered with water are very slippery. Instead of walking across a wet area, have someone hold the ladder for you. 
  • Surface Protection: When dealing with chemical disinfectants, wear a pair of safety gloves, long sleeves, long pants, eye protection, and a face mask.
  • Safety of the ladder: The ladder must be put on a stable and flat surface. Get someone to hold it when you climb in. Do not reach too far or try to stretch too far to get into a place.
  • Wear a Safety Harness: Anchored to a fixed point on all high or sloping roofs, the device stops you from injury in case of an unfortunate fall.
  • When the weather is bad: The sterilization of tools must never be practiced amidst rainstorms, strong winds, snowy weather, or ice conditions, as this poses great risks of accidents.
  • Hire a Roofer: If you are not confident enough about cleaning your roof on your own, it is wise to leave the task to experts like Rick’s Main Roofing. They can inspect the roof and advise you on the safest way to proceed with the roof cleaning.
