A roof should be cleaned at least once every 3-5 years to keep it looking like new. It can also help reveal problem areas that need structural repair.
Besides enhancing your home’s curb appeal, a clean roof helps extend its lifespan by preventing moss and algae growth that degrades roofing materials. Contact Roof Cleaning Charleston SC now!

Algae is the most common cause of dark streaks and blotches on a roof. It usually has a black-green hue and appears as splotches, tufts or patches of discoloration on the surface of the shingles. While it does not damage the shingles, the unsightly growth can reduce the overall aesthetic of your home. Fortunately, algae is relatively easy to clean up once it takes hold.
Before you tackle the job, you should take a few precautions. First, make sure you have the proper safety equipment. A good pair of non-slip shoes, a dust mask and safety goggles are essential for this project. You will also need a ladder that is stable and positioned securely. A garden hose with a spray nozzle will come in handy, as well as a cleaning solution. You can mix a solution of equal parts water and bleach, or purchase a commercially available roof cleaner. Before you apply the solution, wait about 15-20 minutes to allow it time to react with the algae. Then, gently scrub the affected areas with a stiff brush that has nylon bristles. Be careful not to scrub too hard, as you could potentially strip the shingles of their protective granules. Once you’ve removed the bulk of the algae, rinse the entire roof with a garden hose to remove any remaining residues.
Prevention is the best strategy for dealing with algae. You can cut down on future growth by trimming back overhanging branches and keeping up with regular roof maintenance. Improved roof ventilation and the use of zinc or copper strips can also help inhibit growth by releasing natural chemicals that discourage algae, moss and mold.
Moss
Moss is a common problem on roofs, particularly in areas that are shaded by trees or other vegetation and where there are poor drainage systems. It is unsightly, but more importantly, it traps moisture and can cause a lot of damage to tiled or shingled roofs over time. Eventually, the moss will erode the asphalt in your shingles, leaving them vulnerable to water damage and shortening their lifespan. Moss can also block gutters and prevent rainwater and melting snow from draining away properly, further increasing the likelihood of water damage.
There are several ways to remove moss from your roof. The most effective is to use a chemical solution. This can be purchased in a spray bottle and is safe to use on most roofing materials. However, be careful when using a chemical product, as many of them require that you allow it to sit on the moss for a period of time before rinsing off. Moreover, certain chemicals may be toxic to plants and other wildlife in the area.
Another option is to scrub the moss with a long-handled brush. However, scrubbing is labor-intensive and the abrasive bristles can wear down or break off shingle granules. Additionally, this method can be quite dangerous, especially if you are on a ladder or working in hot weather.
To minimize the risk of injury or property damage, it is best to hire a professional to perform roof cleaning and other maintenance tasks. Before hiring a contractor, ask for references from past customers and check their Better Business Bureau rating and accreditation status. You can also consult online reviews and customer satisfaction ratings. Additionally, ask the company about seasonal or package deals that can reduce the cost of roof cleaning and other services.
Debris
Debris like leaves, pine needles, sticks, and fruit can build up on your roof and lead to costly damage if left unattended. These particles can block gutters and cause water to pool on the roof, causing leaks.
The best way to remove these is by using a leaf blower or broom, which are gentle on the roof and won’t loosen shingle granules. It is recommended to start at the ridge of the roof and work your way down to prevent debris from falling on areas you’ve already cleaned. Always wear strong gloves to protect your hands.
You can also use a long-handled brush or rake to remove larger pieces of debris. Make sure to sift through debris to remove any stray nails or other metal, as these can pose a hazard for anyone walking below the roof surface. Lastly, it’s important to clean the gutters during this process so that any organic debris doesn’t fall back onto the roof during the next storm.
Keeping up with the cleaning of your roof is critical to its longevity and health, but it can be difficult for homeowners to do this on their own. A professional cleaner can perform this task safely and efficiently, ensuring that all aspects of the roof are addressed. During the cleaning process, they can also inspect for soft spots or other structural issues that may need to be repaired to prevent future damage.
Professional cleaners use advanced tools and techniques to ensure that your roof is thoroughly clean without damaging the structure or shingles. This includes low-pressure washing and eco-friendly treatments that are safe for your roof. They can also perform a thorough inspection and maintenance of the gutters to prevent clogs and water damage.
Dirt
Dirt and grime can build up on roofs, causing stains that are unsightly and can also reduce the performance of the roof. This dirt can cause leaking and can lead to problems with the insulation or heating and cooling. Regular cleaning can help to remove this buildup and keep the shingles on the roof in good condition.
This can be done by using a broom with a soft brush or a power washer at a low pressure setting. Be careful not to damage the shingles or the roof with the hose and use a gentle scrubbing action. If the roof has a lot of algae growth, it may be necessary to use a bleach solution. Standard bleach, such as the kind used for white laundry or to scrub toilets, is a safe way to kill and remove algae and moss. Rinse the roof after cleaning and ensure that all of the cleaning solution is washed away.
After the washing, a biocide can be safely applied to inhibit future growth of lichen, moss, and algae. This prevents these organisms from returning after the rinsing and can help to protect the shingles on your roof.
The most important thing to remember is that your roof is a major investment. Keeping it clean will protect it from damage and extend its lifespan. In addition, regularly inspecting and cleaning your roof can help to catch any problems before they get worse. It is also important to trim any overhanging branches, which can promote moss and algae growth, and to clean the gutters to prevent them from becoming blocked with leaves or debris.
Mold
Mold can be a real problem, especially in homes with pre-existing respiratory issues. Breathing in mold spores can cause all kinds of health issues from mild allergies to, in severe cases, breathing failure. This is why it is a good idea to do everything possible to prevent mold from growing on your roof. That includes regular cleaning, inspections and maintenance of your roof.
A simple solution of bleach and water works well to kill off any existing mold and keep it from coming back. Just be sure to protect any plant growth on or near the area, such as shrubs or bushes, from the effects of chlorine bleach, which can damage them. Other solutions, such as trisodium phosphate (TSP) can also be used to remove mold and help remove stains on shingles.
Any fungus on your roof, including moss, mildew and mold, can be cleaned with a good quality commercial cleaner. It is best to hire a professional for this, however, because they are experienced in finding all of the nooks and crannies where mold tends to hide. They can also use containment strategies to prevent mold spores from spreading during the cleaning process.
Preventing mold growth is not as hard as many people think, and it starts with making a routine check of your roof a part of your home maintenance schedule. Look for any signs of damage or moisture, which encourages mold to grow, and take action as soon as you see them. Good attic ventilation can also reduce moisture buildup on your roof and can help prevent mold from growing there. It is also a good idea to clean your gutters regularly, as clogged ones can lead to water backup and roof moisture.
