This infographic from the SoftWash Systems “The Heat Is On” campaign illustrates how excessive roof heat can increase residential cooling costs by as much as $400 during the summer. Roofs affected by black algae, mold, mildew, and organic staining absorb more solar heat, raising attic temperatures and forcing air conditioning systems to work harder. Professional roof soft washing removes heat-absorbing contaminants, helping homeowners maintain a cleaner roof, improve curb appeal, and potentially reduce cooling costs. Results vary depending on roof condition, insulation, home design, climate, and local utility rates.
