Blocked gutters can cause several problems: sagging gutters from debris or water weight; damp issues that harm health; loose fixtures falling and causing injury. Neglected gutters also risk structural damage to roofs, walls and foundations from uncontrolled water; unwanted pests like rodents and mold; and damage to a business's customer service and professional image. Regular gutter cleaning is important to avoid these issues and keep gutters functioning properly to drain water away from buildings.
