A leaky roof can turn your home sweet home into a nightmare. A single drop of water finding its way inside can lead to a flood of problems—mold, rot, and costly repairs.
If your roof is leaking, it’s time to act fast and find a contractor who can help.
But before you make that call, let’s dive into the seven most common causes of roof leaks and how to fix them.
Broken Shingles
Shingles are your roof’s first line of defense. When they crack, curl, or go missing, water finds an easy way in. You might notice pieces of shingles in your yard after a storm or see them peeling off your roof.
Replacing broken shingles is a straightforward job. Pry up the damaged shingle with a crowbar, remove the nails, and slide a new shingle into place. Nail it down and seal it with roofing cement. If you’re not comfortable with heights, this is where that good contractor comes in handy.
Clogged Gutters
Gutters are designed to channel water away from your roof. When they get clogged with leaves, twigs, and debris, water backs up and seeps under your shingles, causing leaks.
Grab a ladder and clean out those gutters. Make sure the downspouts are clear too. Installing gutter guards can help prevent future clogs.
Cracked Flashing
Flashing is the metal that seals the edges and seams of your roof, like around chimneys and vents. When it cracks or comes loose, water can sneak through.
To fix cracked flashing, remove the old sealant, lift the flashing, and apply new roofing cement underneath. Press it back into place, nail it down, and reseal the edges. If the flashing is severely damaged, replacing it is the best option.
Skylight Leaks
Skylights bring in natural light, but they can also bring in water if they’re not properly sealed. Leaks around skylights are often due to cracked or deteriorating seals.
Check the seals around your skylight. If they’re damaged, apply a bead of silicone caulk around the edges. For older skylights with persistent leaks, consider replacing them with a new, more efficient model.
Vents and Pipes
Your roof has vents and pipes sticking out of it, and where there’s a hole, there’s a risk of leaks. The rubber around vent pipes can crack over time, letting water in.
For small leaks around vents and pipes, roofing caulk can do the trick. Apply it generously around the base of the pipe. If the rubber boot is damaged, you’ll need to replace it.
Valley Leaks
The valleys where two roof slopes meet are prime spots for leaks. These areas handle a lot of water runoff, and if the shingles are not properly installed, water can pool and seep in.
To fix a valley leak, inspect the area for damaged shingles and replace them as needed. Ensure the valley flashing is intact and securely fastened. If the valley is severely damaged, it may need to be resealed or even rebuilt.
Attic Condensation
Sometimes, the leak isn’t coming from outside. Poor ventilation in your attic can cause condensation, which can mimic a roof leak.
Improve attic ventilation by installing vents or a fan to reduce moisture. Insulating your attic properly can also help keep condensation at bay.
A leaking roof can cause a lot of headaches, but knowing the common causes makes it easier to tackle the problem head-on. Whether it’s a broken shingle or a cracked flashing, quick action and a good contractor can save your home from water damage. Remember, regular roof inspections can catch these issues early, preventing a small drip from turning into a waterfall.
So, the next time your roof starts leaking, don’t panic. Use this guide to identify the issue, fix it if you can, and if not, call in a professional to get the job done right. A well-maintained roof is your home’s best defense against the elements.
