9 Things That Fail a Home Inspection

Roof Problems

While it’s easy to spot an older roof that needs replacing, even newer roofs can have issues. The national average cost to replace aging roof shingles ranges from $10,000 to $36,000, but less obvious problems can be just as expensive.

Improper installation is a common issue, such as the lack of proper flashing or incorrect flashing installation, which can lead to leaks around chimneys or in valleys where two sections of the roof meet. Roof leaks often result in secondary problems, including wood rot, mold, or stained ceilings.

In older roofs, inadequate support can cause significant sagging over time, which may even lead to broken rafters. These issues can be costly to repair and require attention before they worsen.
