How To Clean Wood Shingles
It's best to plan two to four hours for the project's completion. Let's take a look at how to start this project!
Things you'll need:
- 5-gallon bucket
- Soft push broom with a wand
- A pressure washer or garden hose with a spray nozzle
- Roof ladder
- Roofing boots
- Garden hoses
- Wood shingle cleaner
1. Gather Your Materials
It's best to start with a list of tools and cleaners you'll need for your shingle project. An outdoor wood cleaning solution will work to get rid of most surface stains. However, you can also use homemade solutions or stain removers to assist with this. Grab your ladder and set it on the side of your home, making sure that it is on an even surface. Place all of your tools and cleaners near the side of the home so that you don't trip over them. Next, pull out your pressure washer and place it on the lowest pressure setting.

2. Brush Away Surface Dirt
Remove any surface stains by giving the shingles a light scrub with your push broom. You can purchase an extension wand to reach the highest areas of your roof-- if you don't want to climb the roof. Scrubbing the shingles will soften the wood and prepare it for deeper cleaning. It will also help to loosen mildew, mold, moss, and other microorganisms that can grow on the wood shingles.
3. Remove Tough Stains
Pour your stain-removing solution into your pressure washer. Starting at the top of the roof, run the pressure washer over the roof using horizontal sweeping motions. Be sure that the pressure washer is placed on a low setting to avoid damaging the shingles.
Remove any black and blue iron stains using a solution of water and oxalic acid (or any product that contains it). To make this solution, mix 20 parts of water with one part of oxalic acid. You can also add cleaning products to the solution as needed, but avoid products that contain bleach or ammonia. If you have a wood brightener, now's the time to use it.
4. Pressure wash the shingles
After you have removed the tougher stains on the shingles, it's now time to pressure wash them. If you don't have a pressure washer, you can also use a garden hose. You may need to use two or three garden hoses to reach the top of the roof. Also, make sure that your garden hose has a spray gun attachment.
Start at the top of your roof and spray your cleaning solution across it using horizontal sweeping motions. Pay extra attention to any areas where there may be remnants of mildew, lichen, or moss. If the wood shingles are especially dirty, allow your cleaning solution to sit for about 10 to 15 minutes.

5. Rinse the singles
After thoroughly cleaning your wood shingles, pour out the remaining solution from your pressure washer, and go over the roof again with just water to remove any soap residue. You can also use your garden hose for this task if you don't have a pressure washer. Be sure to rinse the roof from the top down to remove any remaining debris, dirt, leaves/branches.

6. Apply a stain
If you want, you can also stain the wood shingles once they have dried from the cleaning. It's best only to apply to the stain when the outside temperature is above 50° Fahrenheit to prevent it from becoming blotchy after it dries. While staining is not necessary, it can help preserve your wood shingles' texture and color. If the shingles look a bit dry or faded, a high-quality stain will restore their shine and help the wood's natural texture stand out.
7. Repeat the process
Regular cleaning is an essential step to keeping your wood shingles looking great decade after decade! So now that you know the process, repeat it every five to ten years.
Homemade Wood Shingle Cleaners
If you prefer to make your own homemade cleaning solutions, here are a couple of options for you to consider.
To create the bleach solution, mix five parts of water with one part of bleach. Then, sprinkle four or five tablespoons of laundry detergent into the mixture, combining them all in a five-gallon bucket or spray bottle. When applying the cleaning solution, be sure to use appropriate equipment, including rubber gloves and protective goggles. Do not use any detergent that contains acetone or ammonia.
Citric Cleaning Solution
If you prefer more of an all-natural solution, you can avoid bleach altogether. Citric-based solutions work wonderfully on a variety of surfaces and are non-toxic and affordable. To make your own citric-based solution, add 20 drops of lemon essential oil to two cups of water and one teaspoon of Castile soap.
Be sure to shake the mixture well and then pour it into a spray bottle or a cleaning bucket. You can also purchase citric cleaning solutions from local hardware stores or online. In fact, many of the commercially available citric-based cleaners also contain agents and oils that can help restore the shine to your wood shingles.
Knowing When It's Time To Replace Wood Roof
Weatherization and age can make your shingles appear old and worn. They may begin to chip, peel, or turn gray. This can affect your home's overall aesthetic, as the roof is one of the first things that people see when viewing a home. Sometimes cleaning just won't cut it, and the shingles will need to be replaced. But how do you know when this is necessary? Here are a few ways to determine whether or not your shingles may need to be replaced:
- Missing shingles resulting in exposed roofing felt
- Splitting or curling
- Significant leaking
- Permanent discoloration
If you notice any of the following issues with your shingles, it may be time to have a roofing expert provide a consultation for a potential roof replacement or the replacement of damaged shingles.

However, many roofing and home improvement experts are completely for it. One of the most important things to remember when power washing the shingles is to set the pressure to a low setting to avoid damaging the wood's surface. It's also a good idea to first spot test the pressure washer to determine if the lowest setting is, in fact, low enough that it doesn't damage the roof.
What Is The Life Expectancy Of A Wood Shake Roof?
While there are a few factors that will determine your particular wood shake roof's lifespan, such as your location, roof type, and the type of wood that you use, the average life expectancy it's about 25 to 30 years. Annual cleaning and regular maintenance can help to increase the lifespan of your wood shake roof.
