A leaky roof occurs when water penetrates through the roofing material, leading to potential damage inside a building. Common causes include worn-out shingles, damaged flashing, or clogged gutters. Over time, leaks can result in mold growth, structural damage, and increased repair costs. To prevent leaky roofs, regular maintenance is essential. Homeowners should inspect their roofs for signs of wear, clean gutters, and address any issues promptly. Using quality materials and hiring professional roofers can also help ensure a durable and leak-resistant roof, protecting the integrity of the entire structure.
