Your roof plays a critical role in protecting your home from the elements. It shields you from rain, wind, snow, heat, and more—day in and day out. But even the most durable roofs aren’t immune to wear and tear. Over time, damage can accumulate quietly until you’re suddenly faced with leaks, mold, or even structural issues.
At AC Matthews Roofing & Exteriors, we understand the importance of staying ahead of roofing problems. That’s why we’ve compiled this comprehensive guide on the top signs that your roof may need repair. Catching these issues early can save you money, extend the life of your roof, and keep your home safe and secure.
1. Missing, Damaged, or Aging Shingles
One of the most visible signs of roof trouble is damaged shingles. Shingles act as the outermost layer of protection for your home, shielding it from rain, sun, and debris. If they are curling, cracking, blistering, or falling off altogether, that’s a clear sign your roof may be compromised.
Here’s what to watch for:
- Curling or cupping: This indicates the shingles are aging or have been exposed to too much heat.
- Cracked shingles: Often caused by wind damage or extreme temperature changes.
- Bald spots: Loss of protective granules means the shingle can’t do its job properly.
- Missing shingles: Wind and storms can tear them off, leaving the underlying layers exposed.
Even a few missing or broken shingles can lead to water infiltration, so it’s important to address this early.
2. Interior Water Stains and Leaks
Discoloration on your ceilings or walls—especially brown, yellow, or copper-colored stains—often points to a roof leak. This moisture may be seeping in from damaged flashing, broken shingles, or cracks around vents or chimneys.
Over time, even small leaks can cause:
- Rotting wood and insulation
- Mold and mildew growth
- Stained or sagging ceilings
- Damaged drywall
If you notice water spots or peeling paint near the ceiling, don’t assume it’s a plumbing issue—it might be your roof.
3. Sagging or Warped Roof Deck
When you look at your roofline from the ground, it should appear straight and even. A sagging or warped area typically means there’s structural damage beneath the shingles, such as rotting decking or damaged rafters.
Common causes of sagging include:
- Long-term moisture intrusion
- Excess weight from snow or pooled water
- Structural aging or improper installation
Sagging sections of a roof are serious and should be inspected immediately by a professional, as they may indicate a potential collapse risk if left untreated.
4. Granules in the Gutters
If you clean your gutters and notice a lot of sand-like granules, that’s another sign your roof is wearing out. Asphalt shingles are coated with granules that protect them from UV rays and improve durability. Over time, these granules start to wear off and end up in your gutters.
Signs of excessive granule loss include:
- Bald patches on shingles
- Discolored or inconsistent roofing texture
- Granules collecting around your downspouts
Once the granules are gone, the shingles are much more vulnerable to damage from the sun and weather.
5. Moss, Mold, or Algae Growth
Biological growth on a roof isn’t just a cosmetic issue—it’s a warning sign of trapped moisture. Moss, algae, and mold tend to thrive in shaded areas and can hold water against the surface of your roof.
Problems caused by moss and mold include:
- Premature shingle deterioration
- Wood rot underneath shingles
- Increased risk of leaks
While a professional roof cleaning can help remove growth, recurring moss often signals that your roof’s drainage or ventilation needs improvement—or that it’s time for a repair or replacement.
6. Higher Energy Bills
If you’ve noticed your heating or cooling bills climbing, your roof might be contributing. Damaged or aging roofing systems can allow hot or cold air to escape, forcing your HVAC system to work harder to maintain a consistent temperature.
Energy efficiency problems related to your roof may stem from:
- Poor attic ventilation
- Damaged or thin insulation
- Leaks or gaps in the roofing structure
Repairing the roof and improving ventilation can help stabilize indoor temperatures and reduce energy waste.
7. Light Showing Through the Attic
A trip to your attic can tell you a lot about your roof’s condition. If you see sunlight peeking through cracks, holes, or seams, it’s a strong indicator that water can—and likely will—find its way in too.
Even small points of light can mean there are gaps in the decking or underlayment, often caused by:
- Missing shingles
- Nail holes or worn flashing
- Animal damage
If you can see daylight, your roof isn’t sealed properly. This is an urgent issue that requires immediate repair.
8. Flashing Failures and Chimney Issues
Flashing is the metal or waterproof barrier installed around roof features such as chimneys, skylights, and vents. Its purpose is to keep water from seeping into those vulnerable areas.
Common signs of flashing problems include:
- Rusted, bent, or detached flashing
- Cracked or missing sealant
- Leaks around the base of chimneys or roof valleys
Faulty flashing is one of the leading causes of roof leaks. It’s often overlooked, but it plays a crucial role in protecting your home.
9. Recent Storm Damage
Storms are one of the most common culprits of sudden roof damage. Hail, high winds, and heavy rain can wreak havoc on shingles, flashing, and roof decking. Even if you don’t see any damage from the ground, it doesn’t mean your roof escaped unscathed.
After a storm, inspect for:
- Debris buildup on the roof
- Dents or bruises on shingles (hail damage)
- Fallen branches or punctures
- Loose flashing or vents
It’s a good idea to have your roof inspected by professionals after major weather events to catch hidden damage early.
10. Your Roof Is Over 20 Years Old
Even if your roof looks fine on the outside, age is a major factor. Most asphalt shingle roofs last between 20 and 25 years. If your roof is approaching or has passed this milestone, it’s time to start planning for repairs or a replacement—especially if you’re experiencing any of the signs listed above.
Older roofs are more prone to:
- Granule loss
- Leaks
- Wind uplift
- General wear and tear
Routine inspections can help you determine whether a few repairs will suffice or if it’s time for a more comprehensive update.
The Importance of Prompt Roof Repair
Delaying roof repair may seem like a way to save money in the short term—but it often leads to much higher costs later. Left unchecked, small issues can evolve into:
- Structural damage
- Interior flooding
- Mold remediation
- Full roof replacements
By addressing roof damage early, you can extend the life of your roof, protect your home’s value, and avoid unnecessary stress.
