Sagging roofs are unsightly and indicate possible structural damage. In this post, residential roofing expert Deschutes Roofing explains the most common causes and solutions for roof sagging.
Water Damage. Moisture encourages the growth of mold and rots the attic’s wooden components. Leaks on your roof will drench your roof’s sheathing and rafters. Damaged sheathing can buckle under the roof material’s weight, making it sag.
Structural Issues. Sheathing and rafters can buckle under heavy roofing material due to poor installation. For example, the sheathing and rafter system for asphalt shingles could deform and bend under a heavier roofing material, such as slate tile.
Aging. Old roofing materials will sag as they reach the end of their lifespan. The structure will lose integrity and bend faster than new, sturdy materials. Roofers must replace the entire roof system, including the materials and structure, if it is beyond the estimated lifespan.
Poor Roofing Materials. High-quality traditional and metal roofing materials have excellent integrity. They are reinforced and tested to withstand different weather conditions. Poor roofing materials will sag faster than high-quality ones.
Consistent inspection and maintenance can reveal your roof’s minor and structural issues that cause sagging. Roofers can patch up leaks and assess your property’s rafters and siding. They may recommend a complete system replacement if they find any severe structural problems.
Sometimes, sagging roofs happen because of defective materials. Have a roofer inspect and verify the defect. Then, take advantage of your roofing warranty.
