A Small Drip Today, a Big Problem Tomorrow

It starts with a faint dripping sound, a small water stain on the ceiling, or a musty smell in the attic. While it may seem minor at first, a leaking roof can quickly turn into a costly disaster.

At Merritt Roofing, we’ve helped thousands of homeowners in Fort Mill, Greenville, Raleigh and the greater Charlotte area detect, prevent, and repair roof leaks, saving them from more extensive damage down the line.

Common Causes of Roof Leaks Every Homeowner Should Know

Roof leaks don’t always announce themselves with a dramatic ceiling collapse. In many cases, they begin subtly, making it essential to recognize the early warning signs. One of the most frequent causes is damaged or missing shingles. Over time, exposure to harsh weather, especially during storm season, can loosen or tear away shingles, exposing the underlying layers to rain. If you notice dark patches on your roof or find shingle granules in your gutters, it could indicate deterioration.

Another common culprit is cracked flashing. Flashing is the thin metal layer installed around roof joints, chimneys, and vents to prevent water infiltration. When it becomes cracked or corroded, it allows moisture to seep through. Rust spots or peeling sealant around flashing are clear signs of trouble. Clogged gutters can also lead to leaks. When debris builds up, water overflows and can back up under the roofline. This not only damages your shingles but can also cause water to pool around your home’s foundation, creating additional risks.

Lastly, aging roofs are naturally more prone to leaks. As roofing materials deteriorate over time, they become brittle and less effective at keeping water out. If your roof is 20 years or older, regular inspections are crucial to catch potential leaks early.

When Is It Time for a Full Roof Replacement?

While some leaks can be repaired, others signal that it’s time for a full roof replacement. But how do you know the difference? If you’re experiencing frequent or recurring leaks, it could be a sign of widespread roofing failure. Consistent water intrusion, even after repairs, often indicates that the underlying structure is compromised.

Another telltale sign is extensive shingle damage. If you notice widespread curling, cracking, or missing shingles, your roof may no longer be providing adequate protection. Similarly, if you spot bald patches where shingle granules have worn away, it’s a sign of aging materials that may require replacement. Interior warning signs are just as important. Water stains on ceilings or walls, sagging drywall, or bubbling paint are indicators of moisture penetration that could be stemming from a deteriorating roof.

Finally, consider the age of your roof. Most asphalt shingle roofs last between 20 and 25 years. If your roof is nearing or exceeding this age, investing in a replacement can prevent future leaks and improve your home’s overall protection.

“ Merritt was fantastic. I spoke with several highly rated companies for our replacement and this crew had a great combination of professionalism, value, and just a great personal connection. Victor and the rest of the team made a tremendous impression on my family and me, and the installation was done quickly and with great skill. I hope I never need to replace a roof again, but if I do, it'll be with these folks! ”

“ I had a complicated roof claim! Ryan was knowledgeable and super patient and assuring with what was going to happen during the process. Remember when the claims rep comes to inspect the damages, he is looking out for himself and his company's interests. A good roof rep will have your back, which is exactly what happened. Merritt Roofing bent over backwards to get my roof up with my intense schedule and I am extremely happy with how everything was handled in a very professional way! The new roof looks great and it got a good report by the inspector. Thanks a lot! Highly recommended. ”

He went out of his way to make sure our roof was taken care of and kept us completely informed the entire time. Couldn't have asked for a better experience for a roofing issue. We definitely know now who to call in the future, thanks Ryan and Merritt Roofing for making it so easy. ”
