When it comes to roof cleaning, frequency is key. It’s recommended that you have us professional inspect your roof every 2-3 years, or after significant weather events like heavy rains or hail storms. Doing so allows professionals to identify damaged areas and take action before they become more serious issues. When assessing the condition of your roof, a professional can look at broken shingles as well as patches of algae growth on the surface and in the gutters. Algae can cause staining and eventually damage the structural integrity of your roof – causing further costly repairs down the line if left untreated. Once any damaged areas are identified by a professional, they should be cleaned using an environmentally friendly cleaning solution that doesn’t contain harsh chemicals which could potentially damage other portions of your home or surrounding environment. This ensures that those unwanted organisms don’t return shortly after cleaning is complete – extending the life of your investment for many years to come!
