A sagging roof is a serious issue that you might notice as dips or a wavy appearance in the roofline. This could indicate structural problems, such as damaged rafters or severe water damage, and requires immediate attention to prevent collapse. Flashing issues are another common problem, typically leading to leaks around chimneys, vents, or skylights. Flashing is meant to seal these vulnerable areas, and when it’s damaged or improperly installed, water can seep in, causing leaks and rot.

Gutter and downspout problems can be identified by overflowing gutters, water pooling around the foundation, or gutters pulling away from the roof. Clogged or damaged gutters can cause water to back up under the roof or damage the foundation, making regular maintenance essential. Ventilation problems may be indicated by excessive heat in the attic, ice dams in winter, or increased energy bills. Poor ventilation can lead to heat and moisture buildup, damaging the roof and reducing energy efficiency.

Roof damage often caused by fallen branches or animals, are typically visible and should be repaired promptly, as even small holes can lead to significant water damage.
