Quick Summary: Savannah Roof Flashing Repair at a Glance

What flashing does:
It’s the thin metal that keeps Savannah’s heavy rain and stormwater from sneaking behind your shingles especially around chimneys, walls, and skylights.

Why it fails:
Coastal humidity, salt air, and intense sun exposure cause metal to rust, sealant to dry out, and fasteners to loosen over time. Around the chimney is the most common place we see flashing leaks in the region!

Flashing Repair options:

• Reseal: When metal is solid but joints have dried out.
• Targeted repair: For isolated rust, cracks, or small leaks.
• Full replacement: When corrosion or poor installation is widespread.

Average Savannah costs:
From $150 for small vent repairs to $1,800 for a full chimney flashing rebuild.

When to act:
Ceiling stains, musty attic odors, or rust streaks mean water is already inside—don’t wait for the next tropical storm to test your luck.

💧 Bottom line:
A $300 flashing repair today can prevent a $10,000 roof replacement tomorrow.

What Is Roof Flashing and Why It Matters in Coastal Georgia

A small flashing leak might not look serious—but trust me, I’ve seen what a slow drip can do in Savannah’s humidity.
Flashing is the thin sheet metal that keeps water from slipping into seams where your roof meets chimneys, skylights, walls, or valleys. It’s one of those details that separates a short-lived roof from one that lasts decades.

Here in our climate, salt air, high humidity, and heat expansion make flashing one of the most vulnerable parts of any roof system.

Common trouble spots include:

• Chimneys: Sealant dries out and mortar cracks.
• Sidewalls & dormers: Step flashing loosens or slips.
• Valleys: Debris holds water, causing hidden rust.
• Skylights: Gaskets fail, letting water creep in.
• Pipe boots & vents: UV light and heat dry out rubber seals.
• Mixed metals: Galvanic corrosion from dissimilar materials speeds up rust.

A small gap at any of these points can send water right into your attic insulation and framing—something I see far too often on coastal homes.

Repair, Reseal, or Replace? Here’s How We Decide

The right fix depends on the condition, location, and cause of the leak.
When we inspect your roof, we look closely at the metal condition, how it ties into the shingles, and whether the deck underneath shows moisture signs.

1. When a Reseal Is Enough

Think of this as maintenance for otherwise healthy metal. If the flashing is intact but sealant has dried out, we clean the surface, remove the brittle compound, and reseal it properly.

✅ Adds 1–3 years of service life when done early.

2. When a Targeted Repair Makes Sense

If the problem is isolated—a slipped step flashing or a rusted valley section—we’ll remove the affected pieces, replace them, and reseal the area.

✅ Durable fix that matches your roof’s remaining lifespan.

3. When Full Flashing Replacement Is Best

When flashing is installed wrong or corrosion is extensive, it’s best to rebuild the detail from the deck up. In most cases you would do this during a full roof replacement of your shingles or metal roof.

✅ Long-term solution that prevents recurring leaks and blends seamlessly with your roof.

DIY vs Professional Flashing Repair

It’s tempting to grab a caulk gun, but flashing is precise work.
If the problem involves a chimney, skylight, or multi-story section, it’s safest (and often cheaper long-term) to let a pro handle it.

DIY-friendly:

• Simple reseal on accessible low-pitch areas
• Replacing a rubber vent collar
• Clearing debris from valleys

Call a pro when:

• The leak involves masonry, skylights, or long wall lines
• There’s visible rust or missing metal
• You’re dealing with a steep or high roof
