When the asphalt shingles on your roof become dirty, not only is it unsightly, but it can actually cause damage to your roof. Below you’ll learn the causes of a filthy roof, How to Clean Asphalt Shingles and preventative steps you can take to minimize dirt and grime on your roof.
The Causes Of A Dirty Roof
Most of the dirt, you’ll find on your roof, comes from overhanging trees. Leaves, limbs, acorns and other tree debris can form a dam on your roof and prevent rainwater from properly flowing off your roof. This often leads to roof leaks and a damaged roof. Constant shade from trees and moisture on the asphalt shingles can cause moss and algae to grow on your roof. Moss and algae will grow underneath the shingles, lift them up off the roof and compromise their ability to protect your roof.
Cleaning Method For Asphalt Shingles
Cleaning your asphalt shingles is a simple task, but if you don’t want to climb a ladder to reach your roof, call a professional company that offers roof cleaning to do the job for you. Before cleaning your roof, combine one cup of bleach, one gallon of water and two caps of dish liquid. Place the mixture into a large sprayer and apply it to your roof. Allow the mixture to soak into the shingles for 15 minutes and then rinse off the mixture with a garden hose and a sprayer attachment. If necessary, use a scrub brush that has a long handle to scrub and loosen the moss.
To prevent debris from damaging your roof, trim all tree branches that hang over your house. Attach zinc strips along the top ridge of your roof to keep moss and algae from growing on the asphalt shingles. After learning How to Clean Asphalt Shingles and taking preventative steps to keep moss and algae away, your roof will look better, and you won’t have to worry about debris damaging your roof.
