What is Roof De Mossing & Why It Needs for your Roof?

Roof demossing, also known as moss removal, is the process of removing moss, lichen, and other types of vegetation from the surface of a roof. This is typically done using a combination of pressure washing, scraping, and chemical treatments.

Moss and lichen can damage a roof over time by causing granule loss, which reduces the effectiveness of the shingles in protecting the interior of the building. Moss and lichen can also retain moisture, which can lead to rot and leaks.

Roof Demossing is important for maintaining the longevity of the roof and preventing costly repairs. If you live in an area with high humidity and lots of rainfall, it may be necessary to have your roof de mossed every year or two. It is recommended that you hire professional and experienced roofing contractor to do this job safely.

Methods of Roof De-Mossing

There are several methods of roof de mossing, including:

Pressure washing: High-pressure water jets are used to remove moss, lichen, and other debris from the roof surface. This is a quick and effective method, but it can also be harsh on the roofing materials.

Scraping: A scraper or other similar tool is used to manually remove moss and lichen from the roof surface. This is a more gentle method, but it can be time-consuming.

Chemical treatments: Chemicals such as zinc sulfate or sodium hypochlorite are applied to the roof surface to kill moss and lichen. These chemicals can be effective, but they can also be harmful to the environment if not used properly.

Manual removal: This method involves physically removing moss, lichen, and debris from the roof by hand. This is the most gentle method, but it is also the most time-consuming and labor-intensive.

Roof Cleaning using Brush: This method involves using a stiff brush to remove moss, lichen, and debris from the roof surface. This is a more gentle method, but it can be time-consuming. It is recommended to use a long handled brush to keep yourself safe.

The best method to use will depend on the type of roofing materials, the severity of the moss and lichen growth, and other factors. It is important to hire a professional and experienced roofing contractor who can assess your roof and recommend the best method for your specific situation.
