There’s nothing quite as stressful as discovering a roof leak. Whether it’s a slow drip in the attic or a sudden water stain on the ceiling, leaks can quickly lead to bigger headaches like mold, wood rot, or interior damage. The good news? Most leaks can be traced back to a few common causes—and if you know what to look for, you can catch problems early and keep your home protected. Here are five of the most common reasons roofs leak, and what you should do if you spot one.
1. Your Shingles Are Missing or Damaged
Shingles are your roof’s first layer of protection, and when they’re compromised, it doesn’t take long for water to find its way in. Storms, age, and even wind can cause shingles to crack, curl, or come loose altogether.
What to Do:
After a storm or heavy winds, take a few minutes to visually inspect your roof. If you see bare patches or shingles that look out of place, it’s a good idea to have a roofing professional take a closer look and replace any damaged sections.
2. Flashing Issues Around Roof Features
Flashing is the metal material installed around things like chimneys, skylights, and vents to seal the seams and prevent leaks. Over time, flashing can crack, rust, or pull away from the roof, creating gaps that let water sneak through.
What to Do:
If you notice water spots near a chimney or skylight, there’s a good chance your flashing is the culprit. This is one of those repairs best left to the pros—proper flashing is essential for keeping water out of tricky spots on your roof.
3. Clogged Gutters and Downspouts
Gutters are designed to carry water away from your roof and foundation. But when they’re filled with leaves, twigs, and other debris, water can back up under your shingles or pool around vulnerable areas, eventually leading to leaks.
What to Do:
Cleaning your gutters may not be the most glamorous task, but it’s one of the easiest ways to prevent roof leaks. Try to clean them out at least twice a year, or more often if your yard has lots of trees. Gutter guards can also help keep debris out.
4. Poor Attic Insulation or Ventilation
Sometimes the leak isn’t coming from outside—it’s starting inside. A poorly ventilated attic traps warm, moist air, especially in colder months. That moisture can condense on your roof’s interior, leading to mold, mildew, and water damage over time.
What to Do:
Take a look in your attic. If you notice damp insulation or musty smells, it’s a sign your ventilation system may need an upgrade. Adding insulation and ensuring your vents are working properly can go a long way toward protecting your roof from the inside out.
5. Skylight or Chimney Leaks
Skylights and chimneys add a lot of charm to a home—but they also create more opportunities for leaks. If the flashing around these features wasn’t installed correctly or has deteriorated, water can start seeping in around the edges.
What to Do:
Check for water stains or soft spots near skylights and chimneys. If you see any signs of moisture, it’s time to have a professional inspect the area and reseal or replace the flashing as needed.
Some roof leaks are easy to fix—but others require a trained eye. If you’ve tried to track down the source of a leak and come up empty, or if the same issue keeps popping up, it’s time to call in a roofing expert.
