Though it is imperative to do so at times you should try to avoid pressure washing your roof where possible. Though there are benefits when necessary power washing will still accelerate weathering on your shingles and too much could reduce the life expectancy of your roof. The best way to care for moss and algae on your roof is to prevent it. You can do this by applying moss killer annually or biannually or in some cases zinc strips may help to a limited extent. However zinc strips do seem to lose their ability to prevent moss over time and in some cases moss is even seen to grow on the zinc itself. Thus we would recommend regularly applying some kind of moss killer instead. You can find granulated or powdered treatment at your local hardware store or make your own bleach solution at home which can be applied by using a pump garden sprayer, some people just use baking soda or laundry detergent (which may not be good for the environment). The important thing is to kill the moss before you see it growing, don't wait until it is a problem before you apply treatment. The most common problem, when it comes to preventive maintenance, is usually not due to an inability to perform the needed care but rather, due to our very busy lives, we most often just simply forget or never find the time until the problem has already resurfaced and it is too late. That is why Practical Pressure offers a scheduled moss prevention program so that you don't have to worry about forgetting or finding the time. Having Practical Pressure prevent moss from growing on your roof can save you a lot of money by avoiding the need for professional cleaning. Also by avoiding the wear and tear caused by moss growth and pressure cleaning you can expect to get more years out of your roof before having to replace it. |
