Removing Debris

Pine needles, branches, sticks, and leaves will often collect on top of your roofing system mainly by wind even more if your home is close to trees. You can get rid of that debris by climbing onto your roofing system and clearing big pieces of present debris. You can do that by using your hands. Next, you can use a broom or a brush to sweep dirt and small debris. If you have a leaf blower, you can use it to remove every last debris particle, but be careful not to lose balance.

Removing Moss

Moss can cause significant problems to your whole property. If you leave it on your roofing system, you will probably end up dealing with a roof leak in no time. You can remove moss by following the next steps. First, you need to prepare basic cleaning solution made out of baking powder or soda, liquid dish detergent, ammonia or bleach and salt mixed with hot water. Saturate all areas where moss is present and leave it to soak for a couple of hours. After that, the moss will die, and the next rain will wash it down. Don’t forget to remove it from your gutters.

Removing Algae

To remove the algae growth on your roof, you can use an acidic solution such as a mixture of water and vinegar (50/50). Saturate your roofing materials where algae or black spots are present and then use a broom or a brush to clean all areas covered in stains.

What Not to Do

Just to clear things out we will mention some things which you should never do to your roofing system. A pressure washer is a big no-no when it comes to cleaning the roof. You can easily damage your roofing material by shooting pressurized water at it. Every cleaning solution you make should be tested on a tiny sample of your roofing system so you can be sure that it won’t damage your roofing material. Always use soft brushes when cleaning the roof, rugged brushes and brooms can damage your roofing material or tear off granules and remember always to start from the top, so you won’t step on a slippery surface and fall.
