What is one sign of a failing roofing system?

The presence of curled or buckled shingles is a clear sign of a failing roofing system. This condition indicates that the shingles are experiencing significant wear and may not be adhering properly to the roof's surface. Curling or buckling can be caused by a variety of factors, including age, inadequate ventilation, or excessive heat exposure. These deformities compromise the shingles’ ability to protect the underlying structure from water infiltration, leading to potential leaks and more serious damage to the home.

In contrast, consistent uniformity in shingle color suggests that the roofing material is still in good condition and has not undergone fading or damage. A low roof pitch is a design characteristic rather than a sign of failure; while low pitches can have implications for drainage, they do not inherently indicate that the roofing system itself is failing. Finally, the installation of correct drainage systems is a proactive measure that contributes to the longevity of a roofing system and does not indicate failure. Rather, it helps prevent issues such as pooling water which could lead to damage over time.
