5 Reasons Your Roof Is Leaking

Most homeowners are primarily concerned with their property’s façade, ensuring it always stays clean and presentable. However, the roof is just as important as it does the essential job of protecting you and your household from the elements. When it starts to leak, you’ll quickly grow tired of replacing a drip bucket each time it rains, which may end up overflowing and damaging your floors.

Roofing issues, when left unaddressed, can result in thousands of dollars of damage. Whether your roof is only a few years old or several decades, it needs a routine inspection to ensure it stays in good working condition, saving you from having to replace it. Here are the most common causes of roof leaks:

1. Cracked Flashing

Your flashing is the thin pieces of metal that form a water-resistant barrier in your roof, installed under the shingles and on the joints. They can be concealed or exposed. If you choose to have them visible, they resemble long sheet metal strips, but if they’re hidden, they’ll be covered with a rubberized coating. 

If your flashing is broken, wind and rain can cause it to corrode, making it break apart. Rainwater will have an easier time seeping through, immediately resulting in leaks. To prevent this, you’ll need to call roofing contractors to survey your roof once or twice a year to look at your flashing and ensure it’s in good condition. If they spot a problem, they can address it immediately, preventing it from cracking.

2. Broken Shingles

Your shingles are one of your roof’s most easily recognizable elements since they form its exterior layer. That means it’s easy to spot missing shingles since you can quickly see missing patches where your shingles should be. Sometimes, you can find the shingles in your yard after a heavy storm has passed. They also protect your roof from the rain and wind, so water has an easier time infiltrating your home when there are missing pieces.

3. Improperly Sealed Valleys

Valleys on your roof are sloped areas where two planes of the roof join. If these valleys are incorrectly sealed, rainwater can enter your home. You can check for improperly sealed valleys by searching for wet spots that run the length of your roof’s seams. This error can happen due to incorrect sealing, being stepped on regularly, or erosion caused by excess rain or ice.

4. Cracked Vent Booting

Roof vents are responsible for expelling excess moisture from inside the home, ensuring good indoor air circulation. If your vent booting is cracked, it will manifest in leaks that leave dark spots and musty smells. 

Roofers seal vents by putting flashing around the openings and putting a tight rubber boot over the area the pipe juts out of the roof. After enough time and exposure to the elements, the flashing may break off, or the roof can decay, causing the vents to crack.

5. Ice Dam Buildup

An ice dam is ice that forms at the roof’s edge, preventing melting snow from reaching the eave and freezing in place. When the ice accumulates and gets too heavy, it can impair the roof. 

An ice dam buildup occurs when the heat from your attic rises and causes the snow to melt, making the water flow between the roof’s surface and refreezing into ice when it reaches the exterior edge. When this happens, it’s best to contact a roofing company to inspect the problem and address it right away to prevent further damage from occurring. 


A leaking roof may sound like a minuscule problem, but it can quickly lead to water damage, which will then lead to mold and mildew growth, causing a host of respiratory problems. By familiarizing yourself with the common causes of roof leaks, you can identify issues right away and contact a roofer to fix them immediately.
