The gutters are the complement to the roofing, since they guide therainwater in the desired location in order to protect the house but also the land. Well-designed and well-maintained gutters protect water infiltration in the house, thus avoiding potentially costly damage to the frame, insulation, the appearance of mold, etc. Additionally, directing water runoff away from the foundation can help prevent soil erosion around the home.
