A missing shingle refers to a section of roofing material that has been lost or removed from a roof. This can occur due to factors like strong winds, improper installation, or wear and tear over time. Missing shingles can expose the underlying roof structure to the elements, potentially leading to leaks and further damage if not addressed promptly.

Shiny shingles typically refer to asphalt shingles that have lost their granules, exposing the underlying fiberglass mat. This exposure can cause the shingles to appear shiny or reflective, especially in sunlight. This shine is often a sign of wear and aging, indicating that the shingles may need to be replaced to prevent potential roof damage.

Curled shingles are roofing shingles that have started to lift or curl at the edges or corners. This curling can occur due to several factors, including age, poor ventilation, or exposure to harsh weather conditions. They can compromise the roof's ability to protect against water infiltration, leading to leaks and further damage if not addressed. They are often a sign that the roof may need repair or replacement.

Blistered shingles feature raised bubbles caused by trapped moisture or gas within the shingles, often due to manufacturing defects or inadequate ventilation. While small blisters might not immediately harm roof performance, they can lead to granule loss, reducing shingle lifespan and potentially causing leaks if unaddressed.
