Signs of roof damage include missing or broken shingles, curling or buckling shingles, granule loss, water stains on ceilings and walls, mold or mildew, a sagging roof deck, and damaged flashing or sealants. BYLTup, a licensed Long Beach, California roofing contractor, recommends a professional inspection when homeowners notice these signs. A roof near the end of its expected lifespan, or dented or punctured after a storm, also deserves attention. ## What do missing or broken shingles mean? Missing or broken shingles are one of the most apparent signs of roof damage. They expose the underlying roof layers to the elements, raising the risk of water infiltration and structural decay, and over time can lead to rot. BYLTup advises homeowners to check their roofs for gaps, inconsistencies or visible shingle damage, especially after storms. ## What do curling or buckling shingles indicate? Curling or buckling shingles indicate that shingles are deforming from age, sun exposure or extreme weather. Water can seep through the resulting gaps, raising the risk of leaks and further roof deterioration. Both conditions weaken the roof's ability to shed water efficiently, so BYLTup says they should be addressed immediately. ## Why does granule loss matter for a roof? Granule loss matters because the tiny sand-like granules on shingles protect them from UV rays and weathering. As granules wear away, often collecting in gutters or downspouts, the shingles are exposed to sunlight and deteriorate faster. BYLTup describes granule loss as less obvious than other signs, but still a critical indicator of roof damage. ## What do water stains, mold and mildew mean for a roof? Water stains on ceilings and walls are often the first visible sign of a roof leak, and mold or mildew can follow. Discolored patches or streaks suggest water is seeping through the roof. Mold thrives in the moist environment and poses health risks, particularly for people with respiratory conditions. Musty odors or visible mold call for immediate action on the leak. ## What does a sagging roof deck mean? A sagging roof deck indicates serious structural damage to a roof. It is often caused by prolonged water exposure or by excessive weight from debris or snow. BYLTup says this condition requires immediate professional attention to prevent further roof damage or even collapse, so homeowners who see sagging should not wait. ## What do damaged flashing and worn sealants signal? Damaged or missing flashing and cracked or worn sealants signal weak points in a roof's waterproofing. Flashing keeps water out of vulnerable areas around chimneys, vents and skylights, while sealants around roof penetrations can show peeling or gaps. Either failure can let water in, so BYLTup recommends regular inspection of these areas to catch leaks early. ## How long do different roofing materials typically last? Roof lifespan varies by material. According to BYLTup, asphalt shingles typically last 20-30 years, while metal roofs can last up to 70 years. As a roof approaches its expected lifespan, BYLTup says more frequent inspections and possible replacement may be necessary to catch developing damage before it becomes costly. ## What damage can severe weather cause to a roof? Severe weather can cause significant structural damage to roofs. After storms, BYLTup advises checking for missing or damaged shingles, dents or punctures. Addressing storm-related damage promptly helps prevent long-term problems and preserves the roof's structural integrity, so homeowners should look over their roofs soon after severe weather. ## When should a homeowner call a professional roofer?
