Cleaning Your Roof in Cleveland

When it comes to cleaning your roof, there are some very important dos and don’ts. Old age, weather conditions and normal wear can lead to some aesthetically unappealing roofs.
Short of replacing your roof, sometimes a decent cleaning can improve the look greatly. However, it is VERY important to keep a few things in mind in order to prevent damaging your roof. Cleaning your roof isn’t highly recommended, as doing it incorrectly can severely damage your roof. Many contractors and professionals will tell you that the only time to clean your roof is if you have a very specific reason or need to. While it may not look great, as long as your roof is functioning properly, it doesn’t need to be touched.
A common problem with older roofs or homes in a warm, humid climate is algae. It appears as black, mold-like streaks and stains. While it doesn’t cause harm to the roof, it can make your roof look old and worn. While replacing the shingles with copper-laced ones will kill the algae, it can be expensive. A less costly solution is to very delicately wash your roof.
The most important part of this process is to refrain from using a pressure washer. This could very severely damage your roof. By pressure washing the roof, shingles will most likely become uprooted and this can cause leaks. Also, be sure to test any cleaning mixture you plan to use on some extra shingles, just in case there is a negative reaction. If you don’t have any extra shingles from when the roof was installed, you can purchase a bundle of them at a local home improvement store for relatively cheap.
Cleaning Mixture:
• 50% Water
• 50% Bleach
Using a spray washer, spray the mixture throughout the rooftop. Remove the algae with a SOFT broom or brush. Then spray the roof with water to remove any leftover algae or solution.
• Do NOT use a hard-bristled broom or brush. This can wipe away important asphalt granules that protect roofs from leaks.
• Be sure to spray the plants around the foundation first with JUST water. It will protect them from the bleach in the mixture.
• To prevent algae from growing in the future, you can insert 6-inch-wide strips of zinc or copper under the shingles that are closest to the roof peak.
