A leaking roof can cause more than just a minor inconvenience—it can lead to structural damage, mold growth, and costly repairs if ignored. In Keller, TX, where the weather can shift from blazing heat to intense hailstorms, your roof takes a serious beating year-round. Understanding the most common causes of roof leaks—and how to fix them—can save homeowners time, money, and stress.
1. Damaged or Missing Shingles
Shingles are your roof’s first layer of protection. If they are cracked, curling, or missing altogether, water can easily infiltrate your home. High winds and hail in Keller often contribute to shingle damage.
Fix: Replace damaged or missing shingles immediately. A professional roofer can ensure proper alignment and sealing to prevent future problems.
2. Cracked Flashing
Flashing is the thin metal installed around roof joints and penetrations like chimneys and skylights. Over time, flashing can crack, rust, or pull away, allowing water to seep in.
Fix: Replace or reseal damaged flashing with weather-resistant materials. This job is best handled by a qualified roofing contractor to ensure watertight protection.
3. Poorly Sealed Roof Vents
Vents regulate airflow in your attic, but if they’re not sealed properly, rainwater can enter around the base of the vent. Common signs include moisture stains or leaks around the vent area.
Fix: Re-caulk or reseal the vent flashing. If the vent itself is damaged, it may need replacement.
4. Clogged Gutters
Gutters are essential for directing water away from your roof. If they become clogged with leaves, granules, or debris, water can pool on your roof and seep into the underlayment.
Fix: Clean your gutters regularly and install gutter guards if necessary. Ensure proper downspout drainage to protect your roof and foundation.
5. Skylight Leaks
Skylights add beauty and natural light, but they are notorious for leaking if not installed or maintained correctly. Leaks often occur around the perimeter where flashing or sealant has deteriorated.
Fix: Check the flashing and reapply sealant as needed. In cases of severe leaks, consider replacing the skylight or re-flashing it professionally.
6. Ice Dams (in Cold Snaps)
Though not frequent in Keller, TX, unexpected cold spells can lead to ice dam formation on the edges of roofs. These dams block melting snow from draining properly, forcing water under the shingles.
Fix: Improve attic insulation and ventilation to maintain even roof temperatures. A roofer can install ice and water shield underlayment to provide added protection.
7. Roof Age and Wear
Roofs don’t last forever. As shingles age, they lose their protective granules and become more vulnerable to leaks. A roof that’s 20 years or older is especially prone to problems.
Fix: Have your roof inspected by a professional. If it’s nearing the end of its life span, replacement may be the most cost-effective long-term solution.
8. Chimney Wear and Tear
Cracks in the mortar or flashing around your chimney can create pathways for water. This is a common issue in older homes and after major weather events.
Fix: Tuckpointing (replacing damaged mortar) and flashing repair or replacement are the best solutions. A roofing pro will evaluate whether a partial or full rebuild is necessary.
9. Improper Installation
Sadly, not all roofers follow best practices. Poor workmanship—like bad nailing techniques or misaligned shingles—can lead to chronic leaks.
Fix: Always hire a licensed and experienced contractor. If improper installation is the cause, sections of the roof may need to be redone to prevent ongoing issues.
10. Condensation and Ventilation Issues
Sometimes what looks like a roof leak is actually condensation caused by poor attic ventilation. Trapped moisture can mimic the effects of a leak, causing mold and staining.
Fix: Ensure your attic has proper intake and exhaust vents. This promotes airflow and reduces moisture buildup.
