Masterful Instructions
Begin the inspection from the ground using high-powered binoculars to identify obvious defects such as missing, slipped, or cracked shingles and tiles before setting up a Type 1A industrial-grade ladder on stable, level ground. Position the ladder at a four-to-one ratio against the fascia and extend it at least three feet above the roofline, ensuring it is secured to the structure to prevent lateral shifting. Once you have reached the eave, perform a visual scan of the field shingles to identify granular loss, cupping at the edges, or fish-mouthing where the center of the shingle buckles upward. For clay or concrete tiles, look specifically for hairline fractures or corner chips that could allow water to bypass the primary shedding layer and reach the underlayment. Carefully examine the valley areas where two roof planes meet, as these are high-flow zones prone to debris accumulation and accelerated wear. Check the integrity of the starter course at the eave for proper adhesion and ensure that no fasteners are proud or backing out, which creates a shiner that can transport moisture directly into the roof deck. Verify that the overlap of each course meets the manufacturer’s specified exposure—typically 5 inches for standard three-tab shingles—to ensure the head-lap provides a secondary moisture barrier. Conclude the inspection by checking the rake edges for wind-lift damage and ensuring all ridge caps are firmly seated and free of cracks.
Look for sidings of granules in your gutters; if you find more than a half-inch of mineral grit in the trough, the shingles have reached their hydrophobic limit, meaning the asphalt is exposed to UV rays and will become brittle and fail within 12 to 24 months.
