Summary
From heavy rain to fallen branches, roof leaks in Lexington can strike in any season. Discover the top causes and how to prevent costly damage year-round.
Roof leaks can start small—a water spot on the ceiling, a little discoloration around a vent—but left unchecked, they can lead to structural damage, mold, and costly repairs. In Lexington, KY, where each season brings its own roofing challenges, understanding the most common causes of roof leaks is your first line of defense.
Whether you live in a historic home near Ashland or a new build in Hamburg, here are the most frequent culprits behind roof leaks in the Bluegrass region.
Key Takeaways:
- Lexington weather, trees, and age-related wear all contribute to roof leaks
- Leaks often form around flashing, valleys, vents, and chimneys
- Proper maintenance and inspections can prevent seasonal damage
- Most roof leaks are repairable if caught early
Damaged or Missing Shingles
Lexington storms—especially in spring and early summer—often bring high winds and hail. Over time, shingles can lift, crack, or tear off entirely. Missing shingles expose your underlayment and decking to moisture, leading to fast deterioration.
Homes in open areas like Masterson Station or around Jacobson Park are particularly vulnerable to wind-driven shingle damage.
Failed Flashing Around Roof Features
Flashing is the thin metal installed around roof penetrations (like vents, chimneys, and skylights) and along valleys. Its purpose? To direct water away from vulnerable areas. But when flashing pulls loose or rusts through, water can seep in.
Chimney flashing is a top leak source in older Lexington homes, especially near Bell Court and Woodland Park.
Clogged or Damaged Gutters
Gutters play a major role in protecting your roof. When they’re clogged with leaves or improperly pitched, water can back up under shingles. This is especially problematic in tree-lined neighborhoods like Chevy Chase or Lansdowne.
In winter, clogged gutters can also contribute to ice damming—another common cause of leaks.
Poor Attic Ventilation and Insulation
A poorly ventilated attic traps moisture and heat, causing condensation beneath your roof deck. Over time, this leads to warping, mold growth, and water damage that can mimic a roof leak.
In Lexington’s humid summers and icy winters, proper airflow is essential. Ridge vents, soffit vents, and balanced insulation all play a part.
Improper Installation
Some leaks are less about age or weather and more about poor workmanship. Incorrect shingle layering, underlayment gaps, and sloppy flashing installation can allow leaks to develop within months of a new roof being installed.
That’s why it’s essential to work with licensed, certified contractors familiar with Lexington’s climate and building codes.

Ice Dams and Freeze-Thaw Cycles
Lexington winters aren’t always harsh, but even one freeze-thaw cycle can cause problems. When melting snow refreezes at your roof’s edge, it creates ice dams that trap water above them. That water can seep under shingles and into your home.
Homes in sloped neighborhoods like Chilesburg and Andover are at particular risk.
Skylights and Roof Windows
Skylights can be a beautiful feature, but if they’re not sealed correctly or if flashing deteriorates, leaks often follow. Signs include staining around the skylight or visible water trails inside your home.
If your skylight is older than 15 years or wasn’t installed by a roofing specialist, it may need resealing or replacement.
Roof Valleys with Poor Drainage
Valleys (where two slopes meet) handle large volumes of water. If improperly sealed or lined with low-quality materials, valleys are one of the first places leaks develop.
You may see dark streaks or puddles near interior walls if a valley leak goes unchecked.
Cracked Pipe Boots and Roof Vents
The rubber boot that seals around your plumbing vent pipe can dry out and crack after years of UV exposure. When this happens, rainwater slips through the gap around the pipe.
Vent leaks often show up as small ceiling stains in bathrooms, laundry rooms, or near HVAC units.

You can’t stop every storm, but smart upkeep can go a long way in preventing leaks:
- Schedule professional inspections every spring and fall from the best roofers in Lexington
- Clean gutters and downspouts regularly
- Trim overhanging trees near your roof
