A roof leak is more than just an inconvenience, it can lead to extensive water damage, mold growth, and costly repairs if left unchecked. Understanding what causes roof leaks is the first step in preventing them. Today, we at Suburban Roofing would like to discuss the top causes of roof leaks and how to stop them before they start.
Damaged or Missing Roofing Shingles
Shingles are your roof’s first line of defense. Over time, they can crack, curl, or blow off during storms, leaving your roof vulnerable. Even one missing shingle can let water in.
Prevention Tip: After heavy winds or hail, inspect your roof from the ground using binoculars, or hire a professional. Regular roof inspections, at least once a year, can catch missing or broken shingles early.
Clogged Gutters
When gutters are full of leaves, debris, or ice, water can back up under your shingles and seep into your home.
Prevention Tip: Clean your gutters at least twice a year, especially in the fall and spring. Consider installing gutter guards to keep debris out and ensure proper drainage.
Cracked Roof Flashing
Flashing is the metal used to seal joints and edges around chimneys, skylights, and vents. Over time, flashing can rust, crack, or pull away, letting water sneak in.
Prevention Tip: Have flashing checked during annual roof inspections. Promptly replace any cracked or lifted flashing before leaks form.
Improperly Sealed Roof Valleys
Roof valleys are where two slopes meet, directing rainwater down and off your roof. If these aren’t properly sealed, they become prime spots for leaks.
Prevention Tip: Make sure roof valleys are properly installed with high-quality materials, especially if you’re replacing your roof. Look for signs of dampness or stains along valleys inside your home.
Poorly Installed Skylights or Vents
Skylights and roof vents are notorious leak spots if not installed correctly. Improper seals or flashing can quickly lead to water intrusion.
Prevention Tip: Always hire experienced professionals for installation. If you notice drips or discoloration around skylights or vents, schedule an inspection immediately.
Cracked Chimney Mortar
The mortar and bricks around your chimney can deteriorate over time, creating gaps where water can seep through into the roof structure.
Prevention Tip: Have your chimney inspected and tuck-pointed (repaired with new mortar) if you see crumbling or gaps. Chimney caps and flashing should also be checked regularly.
Roof Age & Wear
Even the best roof materials wear down over time. UV rays, temperature changes, and natural aging can all contribute to leaks.
Prevention Tip: Know the age of your roof and its expected lifespan. If your roof is over 20 years old, it may be time to start budgeting for a replacement to avoid unexpected leaks.
