Removing algae and lichen from roof shingles can be an important task for maintaining the longevity and appearance of your roof in Peabody, MA. Algae and lichen growth on roof shingles can cause discoloration, streaking, and other unsightly blemishes that can detract from the appearance of your home. Additionally, algae and lichen can trap moisture on the roof, leading to rot and other forms of damage.

Before attempting to remove algae and lichen from your roof, it is important to consider the type of shingles that are present on your roof. Some types of shingles may be more susceptible to damage from cleaning methods than others. Additionally, it is important to consider the age of your shingles, as older shingles may be more brittle and more prone to damage from cleaning methods.

What can I do about it

One of the most common methods for removing algae and lichen from roof shingles is through the use of a pressure washer. Pressure washing can be an effective way to remove algae and lichen from your roof, but it is important to use a low pressure setting to avoid damaging the shingles. Additionally, it is important to avoid using high pressure water near the edges of the shingles, as this can cause the shingles to lift or curl.

Another method for removing algae and lichen from roof shingles is through the use of chemical cleaners. There are a variety of chemical cleaners available on the market that are designed specifically for removing algae and lichen from roof shingles. These cleaners can be applied with a garden sprayer or a paint roller, and then allowed to sit on the shingles for a period of time before being rinsed off with a garden hose.

Before applying any chemical cleaners, it is important to read the manufacturer's instructions and follow them carefully. Some chemical cleaners may be harmful to certain types of shingles or to plants and animals that are present in the area. Additionally, it is important to wear protective gear, such as gloves and goggles, when working with chemical cleaners.

A third method to remove algae and lichen from roof shingles is through the use of a copper or zinc strip. This method involves installing a strip of copper or zinc along the peak of the roof. This strip releases copper or zinc ions when it rains, which kills the algae and lichen. This method is a long-term solution, but it is important to note that it does not remove existing algae and lichen, but prevent them from growing again.

Be aware and read instructions

It is also important to note that removing algae and lichen from your roof can be dangerous. It is recommended to hire a professional to do the job if you are not comfortable working on the roof. They have the necessary equipment and experience to do the job safely and effectively.
