3-Step Guide For Using Homemade Solutions To Remove Rust And Moss On Your Home's Tin Roof

If your home has an old tin roof, you may notice areas with rust and moss growing on it. Although you want to restore your roof's appearance, you may be hesitant about using chemicals to clean it. Below is a three-step guide for using homemade solutions to remove the rust and moss made from ingredients that can be found in grocery stores, pharmacies, and department stores.

Step 1:  Treat The Rust With White Distilled Vinegar And Lemon Juice

The first step in cleaning your tin roof uses white distilled vinegar and lemon juice to treat the rust. Both ingredients are slightly acidic and can dissolve the oxidation at its root. 

You will also need a ladder, a garden hose, and a spray bottle attachment. Because a tin roof becomes dangerously slippery when wet, perform this step and the others while standing on your ladder.

In the spray bottle, mix together three cups of vinegar and one cup of bottled lemon juice. Attach it to the garden hose and set the nozzle for a fine mist. While standing on the ladder, saturate any areas where you see rust.

Once you have covered all of the areas, do not rinse the solution off. This is done in the third step to give the acids time to break down the oxidation.

Step 2:  Spray The Moss With A Homemade Treatment

After you have treated the roof in the first step, the next thing to do is use a homemade treatment to kill any moss growing. Moss on a tin roof traps moisture underneath it, increasing the amount of oxidation that leads to rust and eventual deterioration of the metal.

For this step, the ingredients used are oxygenated bleach and tea tree oil. The oxygenated bleach has the same power as chlorinated bleach for killing the moss at the roots but does not contain the harsh chemicals as the latter. Tea tree oil is a natural antifungal that also kills the growth.

Rinse out your spray bottle used in the previous step. Then, add two cups of the oxygenated bleach and four tablespoons of the tea tree oil. Attach it to your garden hose, using the same nozzle setting as in step one.

Spray any moss you see with the treatment until it is soaked. You may also want to cover the area of the roof around what you see to kill any new growth that may be sprouting.

Once you have saturated the moss, wait about an hour before going on to the third step.

Step 3: Rinse The Roof With Your Garden Hose

After you have given the treatments time to work, it is time to rinse the roof off with your garden hose. A pressure washer should not be used for this step. The power behind the water could cause damage to any thin, corroded areas on your old tin roof.

When rinsing with the garden hose, use a spray nozzle that is set slightly back from a full stream. You should have some power, but the spray should be set wide to disperse it. 

Start at the top and rinse the roof using wide, side-to-side swipes. This will ensure full rinsing. After you have done the entire roof, allow it to air dry.

After one treatment, you should see an improvement in your tin roof's appearance. However, if you notice extensive damage while you are cleaning, you may want to contact a residential roofing service, like All American Roofing Incorporated. They can inspect your roof's condition and offer any available options depending on what they find, from repairing the damage to replacing the entire roof.
