In new homes, the integrity of a roof should last 20–50 years. However, there are always unforeseen issues that can cause a leaky roof in the meantime. Here are some of the most common reasons for a leaky roof:
Old roofing materials
If a roof has passed its prime, the materials will start to break down, allowing water to seep into the home. Patch repairs are an option, but at some point, it makes more sense to replace the entire roof.
Pipe boot or flashing problems
Materials used to seal sections of the roof can also contribute to leaks. For example, plumbing and appliance vent pipes are sealed with a rubber boot, which can crack or lift with extended UV exposure. Metal flashing, which is placed between the roofline and other walls, can also be installed incorrectly or begin to shift over time, leading to a leaky roof.
Storm damage
Storm damage restoration often includes leaky roof repairs. Severe wind can rip shingles off or blow fallen trees onto a roof, damaging its structural integrity. Rain, snow, hail, and other elements can also cause roof damage.
Debris and ice damming
If debris or ice begins to significantly clog gutters and downspouts, excess water can flow into a home, resulting in a leaky roof. It’s crucial to maintain a clear drainage system so that water can move across and down a roof, not under it.
