Damaged Flashing
Bent, rusted, separated, or improperly sealed flashing around chimneys, vents, and roof valleys is one of the most common causes of roof leaks.
Schedule a professional inspection within the next few days.
How to Identify This Problem
Look for these warning signs:
- Visible rust, corrosion, or holes in metal flashing
- Flashing pulling away from chimney or wall
- Cracked or missing caulk/sealant around flashing
- Bent or dented flashing sections
- Water stains on walls below chimney or skylights
- Leaks that occur only during heavy or wind-driven rain
Common Causes
Age and Weathering
Years of exposure to sun, rain, and temperature changes causes metal to expand, contract, and eventually fail.
Salt Air Corrosion
In coastal areas like Myrtle Beach, salt spray accelerates corrosion, especially on galvanized steel.
Improper Installation
Flashing installed incorrectly, with wrong materials, or insufficient overlap will fail prematurely.
Storm Damage
High winds can lift, bend, or tear flashing loose from its sealed position.
Sealant Failure
Caulk and roofing cement used to seal flashing edges dry out and crack over time.
Chimney or Structure Movement
Settling foundations or masonry movement can pull flashing loose or create gaps.
Solutions & Repairs
Sealant Replacement
Professional RequiredWhen flashing is still sound but sealant has failed, applying new high-quality roofing sealant restores the water barrier.
Partial Flashing Repair
Professional RequiredDamaged sections of step flashing or counter flashing can be replaced without removing all flashing.
Complete Flashing Replacement
Professional RequiredSeverely deteriorated flashing is removed entirely and replaced with new materials properly integrated with shingles.
Chimney Cricket Installation
Professional RequiredFor wide chimneys, a cricket (small peaked structure) diverts water around the chimney, reducing flashing stress.
Material Upgrade
Professional RequiredReplacing galvanized steel with aluminum or copper provides longer service life in coastal environments.

Frequently Asked Questions
Can I seal flashing myself with caulk?
While applying caulk to small gaps might provide temporary relief, proper flashing repair requires understanding how water flows, using appropriate materials, and ensuring proper integration with surrounding roofing. Improperly sealed flashing can actually trap water. Professional repair is recommended for lasting results.
What flashing material is best for coastal areas?
Aluminum or copper are better choices than galvanized steel in coastal environments due to salt air corrosion. Copper is the most durable and develops a protective patina, but is more expensive. Aluminum offers a good balance of durability and cost for coastal homes.
Do I need to replace all flashing during re-roofing?
Not always, but it is often recommended. Existing flashing in good condition can sometimes be reused if carefully integrated with new shingles. However, since accessing and repairing flashing is disruptive, replacing all flashing during a roof replacement ensures everything has the same lifespan.
