Do you need a roof flashing repair in Savannah?

If you have a roof leak or think your flashing might be the culprit you’re not alone roof flashing repairs are one of the top causes of roof leaks here in the Lowcountry and around Savannah!

I’m Derek Adams with Roofing Experts of Savannah, and for over 16 years my team and I have been helping homeowners across Chatham, Bryan, and Effingham Counties stop leaks before they cause costly damage. If you live in Pooler, Richmond Hill, Port Wentworth, or on Skidaway Island, you’ve probably seen firsthand how our humid coastal weather can wear down even a well-built roof.

Keep reading to learn how roof flashing repair works, what it costs, and how to spot early warning signs before a small drip turns into a major headache.


Flashing Repair Quick Guide:

First, let’s provide you with a basic rundown of what flashing is, what it does, and your options. Flashing is the thin metal installed where anything protrudes from your roof, like a chimney, wall, or skylight. Without flashing, heavy rain and stormwater can sneak behind your shingles, especially around chimneys, walls, and skylights. If it is installed incorrectly, your roof is at a greater risk of leaking. In fact, the top cause for a roof leak is the flashing.

Why does flashing fail? Is flashing more prone to issues near Savannah and Pooler than in other parts of the country? Why, you might ask, well that is easy, it is the coastal humidity, salt air, and intense sun exposure that 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 and when you notice the leak inside, it can be fixed pretty quickly!

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 flashing repair costs:
Small vent flashing repairs may start around $150, while more involved work, such as a full chimney flashing rebuild, can cost up to $1,800 depending on the damage, access, and materials needed.

When to take action:
If you notice ceiling stains, musty attic smells, rust streaks, or water spots near a chimney, vent, wall, or skylight, there is a good chance water is already getting past the flashing. In Savannah, where heavy rain and tropical storms can move in quickly, it is better to address flashing issues early instead of waiting for the next storm to make the problem worse.

Bottom line:
A small flashing repair now can help prevent much bigger problems later, including rotted decking, damaged drywall, insulation issues, and costly roof repairs.

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 thin sheet metal that prevents water from seeping 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. Luckily, while flashing is prone to leaking, it can be replaced or repaired quickly.

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 between dissimilar materials accelerates rust.

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

Why does flashing fail faster in Savannah/Coastal GA?

Flashing is the sheet metal that bridges the joints water loves: chimney-to-roof, wall-to-roof, around skylights and vent pipes. Inland, galvanized steel flashing can go 25 years without complaint. Within ten miles of the Georgia coast, I’ve pulled rusted-through step flashing off 12-year-old roofs on Wilmington Island.

Salt air is half the story. The other half is something most homeowners have never heard of: galvanic corrosion. When two different metals come into contact in a wet, salty environment, one of them sacrifices itself to protect the other. Aluminum flashing nailed with the wrong fasteners, or sitting against copper drip edge, corrodes years ahead of schedule. I see this constantly in homes where a previous contractor mixed materials to save $40.

The flashing looks fine from the driveway. Up close, it’s lace. Add Savannah’s heat. A black shingle roof in July hits 160 degrees, then a thunderstorm drops it 60 degrees in twenty minutes. That expansion-contraction cycle works fasteners loose and cracks sealant joints season after season.

Coastal humidity keeps everything damp long enough for rust to take hold in the gaps.


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

Repair, reseal, or replace: how we actually decide what to do with your flashing depends on the exact issue.

The decision comes down to the metal, not the leak. If the flashing is sound and only the sealant joints have dried out, a proper reseal buys one to three years and costs little. If one section slipped or rusted, say three courses of step flashing behind a dormer, we replace those pieces and weave them back into the shingles. That’s a permanent fix for that spot.

Full replacement makes sense in two situations: corrosion is widespread, or the original installation was wrong. When we replace flashing on roof sections that were built the first time badly, we rebuild the detail from the deck up so it sheds water the way it should. Wrong installation is more common than people think. A continuous “L” flashing run along a wall instead of individual step flashing pieces is the classic shortcut, and it leaks within a decade every time. A proper chimney flashing replacement weaves new step courses into the shingles and locks counterflashing into the masonry, which is the only version that lasts. If your roof has the shortcut version, patching is throwing money at a detail that was never built right.

One detail worth asking any Savannah roofer about: if your chimney is wider than 30 inches measured across the slope, code calls for a cricket, a small peaked diverter behind the chimney that splits water around it. Plenty of older homes here never got one. Water pools behind the chimney, sits, and finds the weakest seam in the flashing. If you’ve repaired the same chimney leak twice, a missing cricket is usually why.

1. Reseal the Flashing
If the flashing is still in good shape but the sealant has dried, cracked, or pulled away, a reseal may be enough. We clean the area, remove the old brittle sealant, and apply a proper roof-grade sealant.

✅ Best for early maintenance and can add 1–3 years of service life.

2. Repair the Problem Area
If the issue is isolated, such as a slipped step flashing, loose section, or rusted valley piece, a targeted repair may make the most sense. We remove the damaged flashing, replace what is needed, and seal the area correctly.

✅ Best for smaller leaks when the rest of the roof still has life left.

3. Replace the Flashing
If the flashing was installed incorrectly, is badly corroded, or continues to leak, full replacement is usually the best option. In many cases, this is done during a full shingle or metal roof replacement so the detail can be rebuilt from the roof deck up.

✅ Best for long-term protection and preventing recurring leaks.


Savannah Roof Flashing Repair Costs

Flashing repairs here in Savannah depend on a variety of factors, from the access point to your roof, the size of the issue, and how long it will take. While other factors, like your pitch, can increase the price, most roofing companies will price flashing repairs based on the size or the time it will take them.

Service ScopeWhat It IncludesTypical Cost
Pipe boot or vent repairReplace boot, reseal, and reset shingles$150–$350
Step flashing tune-upReset or replace a few step flashings$300–$750
Valley repairReplace or patch valley metal and underlayment$600–$1,500
Skylight flashing kitReplace kit and reseal perimeter$500–$1,200
Chimney step & counterflashing rebuildNew step courses, reglet cut, counterflashing, and sealant$700–$1,800

Smart budgeting tips: We like to help homeowners and one thing we recommend is to set aside $500 a year for roofing repairs so you have it when you need it one day in the future. Most roofs have issues around year 10-15, but flashing issues can occur sooner.

  • Bundle small repairs to save on setup costs.
  • Set aside 10–20% for hidden damage.
  • Combine flashing work with re-roofing if your shingles are nearing the end of their life.

Signs You Need Flashing Repair Now

Flashing leaks announce themselves by location. A stain on the ceiling within a few feet of the chimney, a damp upper corner where a wall meets the roofline, a musty smell in the attic near a skylight. Shingle leaks tend to show up mid-ceiling and after heavy rain; flashing leaks often appear with wind-driven rain from one direction, which is why a roof can leak during a nor’easter and stay dry through a summer downpour. If your leak is directional, suspect flashing first.

Outside, look for rust streaks running down from valleys or chimney corners, lifted shingle edges along walls, and cracked rubber collars around vent pipes. That last one is the cheapest fix on this whole page, and UV kills those collars in 10 to 12 years here regardless of how good the roof is.

Inside Your Home

  • Ceiling stains near chimneys, skylights, or upper walls.
  • Peeling paint or bubbling drywall in top corners of rooms.
  • Musty attic odor or damp insulation after rain.
  • Daylight visible around roof penetrations.

Outside Your Roof

  • Loose shingles or cracked sealant where the roof meets walls or dormers.
  • Rust streaks along valleys, chimneys, or skylights.
  • Split pipe boots or sun-brittled rubber collars.

👉 Derek’s Tip: If you notice any of these signs, call before the next coastal storm rolls through. A quick inspection today can save you from thousands in damage later.


What Happens During a Professional Flashing Repair

Roofing (specifically roofing contractors) has a reputation that can make homeowners cautious, and honestly, we get it. That is why we believe in explaining the process clearly, showing you what we find, and walking you through the repair before any work is done. When Roofing Experts of Savannah handles a flashing repair, we follow a careful step-by-step process.

1. Assessment & Prep: We inspect the source of the leak, check the flashing, lift shingles as needed, and examine the underlayment and roof decking to determine how far the issue extends.

2. Repair or Replacement: If it is a minor issue, we may reseal the flashing with the proper roof-grade compound. If the flashing is damaged, rusted, loose, or installed incorrectly, we replace the affected metal, make sure the overlaps are correct, and tie everything into the underlayment properly.

3. Water Testing: When needed, we test the area to ensure water sheds as it should and does not find its way back into the roof system.

4. Cleanup & Documentation: We clean up the work area, treat your property with respect, and provide photo documentation so you can see exactly what was repaired. Warranty coverage is included based on the scope of work completed.


DIY vs Professional Flashing Repair

If you’ve got a stain that matches a roof penetration above it, get eyes on the flashing before the next system rolls in off the Atlantic. Hurricane season tests every shortcut on a roof, and June is already here.

It can be tempting to grab a caulk gun and try to stop a flashing leak yourself, but flashing repairs are more precise than they look. The metal, sealant, shingles, underlayment, and roof pitch all have to work together to move water away from your home. If one part is done incorrectly, the leak can return or spread to the decking, insulation, attic, or drywall.

Roof work can also be dangerous, especially on steep roofs, on two-story homes, on wet surfaces, or in areas around chimneys and skylights. While homeowners can safely check for ceiling stains, attic moisture, or visible damage from the ground, actual flashing repairs are usually best left to a professional. A proper repair should not just cover the problem. It should fix the issue of water getting in.
