2 Best Ways To Remove Plant Stains From Your Roof

Posted on: 13 May 2017

If you have plants that have decided to take up residence on your roof, such as algae, moss, and lichen, even after you remove these plants from your roof, they can leave behind unsightly stains. Here are the two best ways to deal with removing these small plants from your roof and getting rid of the stains that they leave behind.

#1. Eco-Friendly Products

The first and best way to remove small plants from your roof is with eco-friendly products. Eco-friendly products are designed to kill the target plants on your roof, but should not harm other plants or animals when they are rinsed off of your roof.

You can purchase roof cleaning products that are labeled as eco-friendly in the cleaning section of your local department or home improvement store. Eco-friendly roof cleaning products are designed specifically to kill the type of plants that grow on your roof.

Generally, these produces require you to spray them directly onto the plant life that is growing on your roof. You can either manually spray the cleaning product directly onto your roof, or you can use a cleaning attachment on your hose to spray the product on the plants. It may take a few applications to remove and kill all the plant life and stains on your roof; however, these types of products will not harm any nearby plants -- just the ones that you want to get rid of.

#2 Bleach

The second way to deal with killing plant life on your roof is with bleach. With bleach, you'll want to make a bleach water solution by mixing equal parts bleach and water together. Be warned: this will create an extremely strong bleach solution that will stain your clothing. You should wear old clothing when dealing with this type of cleaning solution, as well as gloves and goggles to protect your body.

The best way to apply a bleach cleaning solution to your roof is with a spray cleaning attachment on your garden hose. This will allow you to easily and evenly apply the cleaning solution to your roof. You need to dowse the entire area on your roof where the plants are present. Apply the bleach solution to the area where the plants are growing.

Then, go back a couple of days later and sweep away the plants, which should now be dead, from your roof and spray your roof clean with your garden hose. If any plant life is still present, you are going to want to apply the bleach again. 

If you have trouble removing the plant and stains yourself, contact a commercial roofer in your area.
