Comparing 3 Roof-Cleaning Methods for Stains
There are many roof-staining organisms, such as algae, lichen, and moss, which feed off the organic material on roofs. The longer these organisms go untreated, the more damage they will cause to the roof. It can be difficult to find clear information when researching roof cleaning methods, which is why we created a guide to help you make an informed decision on which roof cleaning service is best for your home’s roof.
High-Pressure Power Wash Roof Cleaning
While this was a popular option, there are newer, safer, and more efficient methods of cleaning roofs now. This method can damage shingles; so if you must use a pressure wash, be wary of the PSI (pounds per square inch) advertised. Unfortunately, this method leaves the root systems of the organisms behind, resulting in quick regrowth.
Chlorine-Bleach Roof Cleaning
Using a mixture of chlorine bleach and other chemicals, such as trisodium phosphate (TSP), this method of cleaning is very cost-effective because the chemicals are inexpensive. By spraying the chemical mixture on the roof, waiting for it to dry, and reapplying it several times as needed, the stains and organisms will come off in the months ahead. We do not recommend this method for cedar shake roofs. Many roof cleaning contractors don’t advertise they’re using bleach. However, if they need to wet plants before, during, or after treatment; if they use a runoff recovery system; or if they cover plants during the cleaning process, they’re most likely using a harsh chemical such as chlorine bleach.
Eco-Friendly, Non-Bleach, Low Pressure Roof Cleaning
Using high-grade eco-conscious products which don’t contain any toxic chemicals like the option listed above, roof cleaning companies lightly rinse the roof free of any organisms or stains. Generally, the results of this method are instant, and lichens, algae, and moss are gone before the contractor leaves your property. While this can be more expensive, technicians use eco-friendly roof shampoo and equipment specifically designed for safe and gentle roof cleaning. This will preserve the integrity of the shingles and won’t damage your landscaping.
Understanding the different types of roof cleaning methods and which one is best for your lifestyle and roof type means you’ll be well prepared to ask the right questions and make informed decisions. Removing ugly roof stains will improve your home’s or business’ curb appeal, and your roof will be restored to its original energy efficient state. Maintaining a clean roof will ensure it lasts for years to come.
