Moss can be a nuisance when it grows on your roof and can cause damage to your shingles and tiles if left untreated. Fortunately, there are a few methods that can be used to kill moss, and one of the most effective methods is by changing the pH balance of the moss and the roof.

The pH balance is a measure of the acidity or alkalinity of a substance. Moss thrives in a slightly acidic environment, which is why it’s commonly found on roofs that have a low pH balance. Remember, pH balances range from 0 to 14 and the lower the number the more acidic something is – with a value of 7 being neutral. Changing the pH balance of your roof and the moss can help to kill the moss and prevent it from growing back, and this is what a moss treatment does.

One way to change the pH balance of your roof is by using Sodium Bicarbonate. This is an alkaline substance, which means that it can help to neutralize the acidity of the moss and the roof. This is an eco-friendly solution that may need more products than other methods.

Another way to change the pH balance of your roof is by using a solution of vinegar and water. Vinegar is an acidic substance, which means that it can help to lower the pH balance of the moss and the roof. To make the solution, mix one-part vinegar with three parts water in a spray bottle and apply it to the affected areas of your roof. Let the solution sit for about 30 minutes before rinsing it off with water.

It’s important to note that while these acidic solutions can be effective in killing moss, they can also damage your roof if not used properly. It’s recommended to hire a professional roof cleaning company to ensure that the solutions are applied correctly and safely.
