Roof Cleaning

Regular cleaning is essential since it ensures it looks excellent. In addition, routine maintenance removes dirt and debris. If you notice moss, fungus, or algae on the roof, that is a sign you need to have it cleaned. Black streaks are one sign of mold that indicate the need for cleaning. Lifted roofs shingles also  

indicate an issue with buildup underneath the surface. Some homeowners even require a Moss/Mildew removal before Solar Panels are placed on their roof. We have you covered.

 This is the simplest kind of cleaning, where a leaf blower or other blowing device is used to blow away any leaves or debris that may have settled on the surface. It is a good option for general cleaning on homes with lots of trees nearby, but it will not be very effective against stubborn marks or moss. 

Pressure washing is the most popular and common form of roof cleaning. It involves using a pressure washer to blast high-pressure unheated water, getting rid of debris, dirt, stains, and some moss and algae. On the downside, the high-pressure nature of this cleaning method can potentially damage any weak tiles or shingles you might have. And it will not kill moss at the core, so a chemical-based clean may be needed if your roof has a lot of plant life on it. 

It is really similar to a pressure wash, but it uses gentle chemicals. This cleaning method is gentler while also being more thorough. It kills moss and algae and rinses away dirt and debris. It will not be quite as effective on stubborn marks and stains, but it is a good choice for an all-over roof clean and will not pose much risk to its structural integrity. 

The soft wash technique is becoming more popular with homeowners around the world due to its in-depth approach. It is quite similar to a pressure washing clean but is extremely low pressure and involves using chemicals, bleach, soap, and water to clean. For a typical soft wash, a diluted bleach solution is first applied, killing any moss, lichens, or algae, as well as cleaning the roof of bacteria and killing most everything in sight. Then, it is rinsed off with water. 

A chemical wash, also known as a non-pressure wash, involves spraying a chemical cleaning solution. The solution may be lye or sodium hydroxide and will kill lichens and algae. Usually, it does not pose much risk to your roof, but the chemicals can damage weak tiles. So, it should be thoroughly checked over for weakness before starting this cleaning. It also will not clear away debris, so it is best suited for mossy surfaces. 

Zinc oxide application is a popular choice on surfaces that are prone to growing moss and algae. Zinc is a toxic substance for moss and lichens, preventing them from growing in the first place. Professionals can even apply zinc strips to your roof or dust it with a zinc oxide powder. It is a good choice for very rainy areas where moss grows more easily, but the strips need to be replaced every few years.
