Summary:
Here’s the thing about storm damage: it doesn’t announce itself. Small problems compound quietly until the next storm exposes them in the worst possible way—usually as water dripping through your ceiling. By then, you’re dealing with emergency repairs, insurance claims, and the stress of finding a contractor during peak season when everyone else needs help too.
This isn’t about creating panic. It’s about giving you a clear picture of what to look for so you can make an informed decision before the 2026 storm season arrives. Let’s walk through the five signs that tell you it’s time to call a professional for roofing services.
Missing or Damaged Shingles After Wind Events
Walk around your property after a windstorm and look down. If you spot shingles in your yard, on your driveway, or caught in your landscaping, your roof is compromised. Wind doesn’t just remove one shingle and call it a day.
Once a shingle lifts or tears off, the ones around it become vulnerable. Wind gets underneath the edges, creating more lift, and suddenly what started as one missing shingle becomes a spreading problem. The underlayment beneath those shingles wasn’t designed to be your primary defense against rain. It’s a backup layer, and it won’t hold up long when exposed to Bay Area weather.
The damage isn’t always obvious from the ground. Sometimes shingles curl at the edges or develop creases without fully detaching. These compromised shingles will fail during the next storm, and when they do, water finds its way in fast.
How Wind Damage Spreads Across Your Roof
Wind hits roofs unevenly. The corners and edges of your roof take the brunt of it, which is why damage often starts there and works its way inward. If you’ve got missing shingles along your roof’s perimeter or near the ridgeline, that’s not random—it’s physics.
High winds create uplift by getting under the edge of a shingle and pulling upward. The adhesive seal that holds shingles down can fail when winds exceed the rating of your roofing material. In the Bay Area, where we saw gusts over 50 mph this past winter, even newer roofs can experience shingle lift if installation wasn’t perfect.
What makes this particularly problematic is the domino effect. When one shingle lifts, it exposes the nail line of the shingle below it. Water can now get under that lower shingle, which weakens its adhesion. During the next wind event, that newly weakened shingle becomes the next casualty. This is why a small section of wind damage can expand into a much larger problem within a single storm season.
The other issue is granule loss. Shingles are covered in protective granules that shield the asphalt layer underneath from UV damage. When wind tears at shingles or causes them to flutter repeatedly, those granules shake loose. You’ll see them accumulating in your gutters like coarse black sand. Once the granules are gone, the asphalt layer underneath deteriorates rapidly under California’s sun, making those shingles brittle and prone to cracking.
If you’re seeing granule buildup in your gutters or downspouts, that’s not normal wear for a roof under 15 years old. It’s a sign that your shingles took a beating and are now aging faster than they should. Left unaddressed, you’re looking at premature roof failure—and that means a full replacement instead of targeted repairs.
What to Do When You Find Missing Shingles
Don’t wait. That’s the short answer. Missing shingles create an immediate vulnerability that only gets worse with time. Every day that passes is another day your roof deck and underlayment are exposed to moisture, UV rays, and temperature fluctuations they weren’t designed to handle.
Start by documenting what you see. Take photos from the ground using your phone. Capture the missing shingles, any visible damage to surrounding areas, and anything in your yard that came off the roof. This documentation matters if you need to file an insurance claim later, and it gives your roofer a head start on understanding what they’re dealing with before they even show up.
Do not climb on your roof to inspect it yourself. Wet roofing materials are slippery, and even dry roofs can be dangerous if you’re not trained to work on them. You can do plenty from the ground with a good pair of binoculars or by walking your property’s perimeter to spot obvious issues.
Once you’ve documented the damage, contact a licensed roofer for an inspection. A professional can assess not just the visible damage but also check for secondary issues that aren’t obvious from ground level—things like compromised flashing, damaged underlayment, or moisture intrusion that’s already started but hasn’t shown up inside your home yet.
The inspection itself usually takes 45 to 90 minutes and should include detailed photos and a written assessment. This gives you a clear picture of what needs immediate attention versus what can wait, and it provides the documentation you need if insurance is involved.
Timing matters more than you think. Roofing contractors book up fast as storm season approaches. If you wait until everyone else is calling for help, you’ll face longer wait times and potentially higher prices due to demand. Getting your inspection done now, while contractors have availability, means you can schedule repairs on your timeline instead of theirs.
And here’s something most homeowners don’t consider: insurance companies pay attention to when you report damage. If you file a claim months after a storm, they may question whether the damage is related to that covered event or if it’s the result of deferred maintenance. Prompt documentation and reporting protect your coverage.
Clogged or Overflowing Gutters Causing Water Backup
Your gutters aren’t just there to keep water off your landscaping. They’re your roof’s drainage system, and when they fail, water backs up under your shingles and into places it should never reach. After a season of heavy rain and falling leaves, clogged gutters are one of the most common—and most ignored—problems Bay Area homeowners face.
When gutters fill with debris, water has nowhere to go but up. It pools along your roof’s edge, seeps under the shingles, and soaks into the fascia boards behind your gutters. That’s how wood rot starts. That’s how leaks develop. And that’s how a simple gutter cleaning issue turns into a multi-thousand-dollar repair.
The damage happens slowly, which is why it’s easy to overlook. You might notice water spilling over the sides during a heavy rain, but if you’re not looking closely, you won’t see the staining on your fascia or the water creeping under your roofline. By the time you spot interior damage—water stains on your ceiling or walls—the problem has been building for months.
How Clogged Gutters Lead to Roof Leaks
The connection between clogged gutters and roof leaks isn’t immediately obvious, but it’s direct. When gutters can’t drain properly, water backs up along the roof edge. This standing water sits against the bottom edge of your shingles, right where they’re most vulnerable.
Shingles are designed to shed water that flows downward, not water that sits against them horizontally. When water backs up from clogged gutters, it finds gaps in the shingle overlap, seeps under the edges, and reaches the underlayment. If the underlayment is older or already compromised, that water goes straight through to your roof deck.
Once water reaches the roof deck, it’s only a matter of time before you see it inside your home. The wood decking absorbs moisture, begins to swell, and eventually starts to rot. This weakens the structural integrity of your roof and creates an environment where mold can thrive. You might not see the mold, but it’s there, growing in your attic and potentially affecting your home’s air quality.
The fascia boards behind your gutters take a beating too. These boards are typically made of wood, and when water overflows from clogged gutters, it runs down the back side of the gutter and soaks into the fascia. Over time, this causes rot that compromises the gutter’s attachment to your home. You’ll notice gutters starting to sag or pull away from the house—that’s a sign the fascia behind them is failing.
In Contra Costa and Alameda counties, where we have oak and redwood trees dropping leaves year-round, gutter maintenance isn’t a once-a-year task. It’s something that needs attention at least twice annually, and more often if you have significant tree coverage over your home. Fall is obvious—leaves pile up fast. But spring brings its own debris from flowering trees and wind-blown material that accumulates over winter.
The good news is that gutter cleaning is relatively straightforward and inexpensive compared to the damage it prevents. A professional gutter cleaning typically costs a few hundred dollars and takes a couple of hours. Compare that to replacing rotted fascia boards, repairing water-damaged roof decking, or dealing with interior water damage, and the math is obvious.
Signs Your Gutters Need Immediate Attention
You don’t need to climb a ladder to know your gutters are clogged. There are ground-level signs that tell you it’s time for maintenance, and if you’re seeing these, your gutters have likely been overflowing for a while.
First, look for water staining on your siding below the gutters. This appears as vertical streaks or discoloration running down from the roofline. It means water is spilling over the gutter edge instead of flowing through the downspouts. If you see this, your gutters are full.
Next, check the ground around your foundation. If you notice soil erosion directly below your roofline, or if water pools near your foundation during rain, your gutters aren’t directing water away from your home properly. This can lead to foundation problems over time, which is a much bigger issue than roof damage.
Plants growing out of your gutters are another dead giveaway. Seeds blow into gutters, settle into the accumulated debris, and sprout. If you’ve got small trees or plants visible in your gutters, you’re looking at years of neglect. That level of buildup doesn’t happen overnight, and it means your gutters haven’t been functional for a long time.
Sagging sections are a structural red flag. When gutters fill with water and debris, they become heavy—much heavier than they were designed to support. This weight pulls on the gutter hangers and fascia boards, causing the gutter to sag or pull away from the house. Once a gutter starts sagging, it creates a low spot where even more water and debris accumulate, making the problem worse.
During a rainstorm, go outside and watch your gutters. If water is pouring over the sides instead of flowing out the downspouts, you’ve got a blockage. Pay attention to where the overflow is happening—that tells you where the clog is located. Corners and downspout connections are common trouble spots.
Inside your home, check your attic during or right after a rain. Look for water stains on the underside of the roof deck, particularly along the edges where the roof meets the walls. Use a flashlight to check for damp spots or discoloration. If you find moisture in your attic after a rain, and there’s no obvious roof damage above it, the water is likely coming from gutter overflow backing up under your shingles.
The fix depends on what you find. If it’s just debris buildup, a thorough cleaning solves the problem. If you’re seeing sagging gutters, damaged fascia, or signs of water intrusion, you’re looking at repairs beyond just cleaning. A professional can assess whether your gutters need reinforcement, if fascia boards need replacement, or if the gutter system itself needs upgrading to handle the water volume your roof sheds during Bay Area storms.
Protecting Your Home Before the Next Storm Arrives
Storm season doesn’t send a warning. It shows up with wind and rain, and if your roof isn’t ready, you’ll find out the hard way. The five signs we’ve covered—missing shingles, damaged flashing, clogged gutters, granule loss, and interior water stains—are your roof telling you it needs attention now, not later.
The cost of waiting is real. Emergency repairs during a storm cost more, take longer to schedule, and create stress you don’t need. Insurance companies scrutinize delayed claims. And the longer damage sits unaddressed, the more expensive the fix becomes. What starts as a few hundred dollars in repairs can turn into thousands if water gets into your home’s structure.
Getting a professional roof inspection before storm season isn’t about spending money you don’t need to spend. It’s about knowing exactly what you’re dealing with so you can make informed decisions on your timeline, not in the middle of a crisis. If your roof checks out fine, you’ve got peace of mind. If it needs work, you’ve got time to address it properly.
We’ve been helping Contra Costa and Alameda County homeowners protect their homes for over 40 years. If you’re seeing any of these warning signs, or if you just want to know your roof is ready for what’s coming, reach out for an inspection. No upfront payments, no pressure—just straight answers about what your roof needs and what it doesn’t.
