A leaking roof is one of the most stressful and costly problems a homeowner can face. Not only can roof leaks cause water damage to your ceilings, walls, and insulation, but they can also lead to mold growth and structural issues if left untreated. Understanding the most common causes of roof leaks and taking steps to prevent them can save you time, money, and headaches down the road. We at Suburban / Larchmont Roofing would like to list the most common causes of roof leaks and what you can do.
Damaged or Missing Roofing Shingles
One of the leading causes of roof leaks is damaged or missing shingles. Shingles protect your roof from rain, snow, and wind. Over time, they can crack, curl, or break due to age, weather exposure, or storms. Missing shingles leave your roof vulnerable to water penetration.
Prevention Tip: Regularly inspect your roof, especially after storms, and replace any damaged or missing shingles promptly. Installing high-quality shingles and maintaining proper attic ventilation can also prolong their lifespan.
Clogged or Damaged Gutters
Gutters are designed to channel water away from your roof and home foundation. When gutters become clogged with leaves, debris, or ice, water can back up and seep under the roof’s edges, causing leaks and damage.
Prevention Tip: Clean your gutters at least twice a year and consider installing gutter guards to reduce debris buildup. Also, check for any damage or sagging that might affect proper drainage.
Roof Flashing Failures
Flashing is the metal material installed around roof penetrations like chimneys, vents, skylights, and valleys. It seals these vulnerable areas to prevent water entry. Over time, flashing can rust, crack, or become loose, allowing water to leak into your home.
Prevention Tip: Inspect flashing during roof maintenance and repair or replace any damaged sections. Ensure that flashing is properly sealed with roofing cement or caulking.
Ice Dams
In colder climates, ice dams form when snow melts on the roof and refreezes near the eaves, creating a barrier that traps water. This trapped water can seep under shingles and cause leaks inside your home.
Prevention Tip: Improve attic insulation and ventilation to keep the roof temperature consistent and prevent ice dams. Removing excess snow buildup on your roof after storms can also help.
Cracked or Worn Roof Sealants
Sealants are used to waterproof various roof components, such as joints and seams. Over time, sealants can dry out, crack, or peel, losing their effectiveness and allowing water to enter.
Prevention Tip: Have your roof sealants inspected regularly and reapplied as needed. Using high-quality roofing sealants can improve durability.
Poor Roof Installation or Repairs
Sometimes, leaks stem from improper installation or poor-quality repairs. Incorrectly installed shingles, flashing, or ventilation systems can create weak points in your roof.
Prevention Tip: Always hire licensed and experienced roofing professionals for installation and repairs. Request references and verify credentials before starting work.
