Removing Debris And Algae Stains
After setting up an extension ladder next to the side of a roof that has algae streaks on it, safety gear should be put on. A hard hat, goggles, shoes with slip-proof soles and a safety harness will prevent an individual from becoming severely injured while they are standing on a ladder. A broom can be used to remove twigs and leaves from roofing materials. A cleaning solution can be prepared by adding equal amounts of oxygenated bleach and water in a backpack garden sprayer’s tank.
After a tank is placed in the center of a person’s back and the tank’s straps are secured over their shoulders, a cleaning solution should be applied to stained surfaces. A scrub brush can be moved gently over stained shingles to loosen algae. Treated surfaces need to be rinsed with water and roofing materials need to dry.
Installing A Zinc Or Copper Strip
A zinc or copper strip secured to a roof will prevent algae from forming. Each time that it rains, zinc or copper will be emitted from a strip and will coat shingles. A zinc or copper coating will also protect roofing materials from moss growth. A roof needs to be measured before purchasing a zinc or copper strip. A strip can be secured to the top of a roof by using a power nail gun to insert roofing nails through the length of a strip.
Removing debris from a rooftop will further protect roofing materials from becoming damaged. Roof Cleaning in Bellingham WA should be completed each year, and professional assistance may be required after severe storms or if roofing materials have been on a roof for many years.
