Flashing Repair in Miami, FL

Flashing Repair in Miami, FL

Flashing repair in Miami typically costs between $250 and $650 for most single-area fixes, and it’s work you want done the moment you spot a problem. Flashing is the metal material, usually aluminum or galvanized steel, that seals the seams where your roof meets a wall, chimney, skylight, or valley. When it fails, water gets in, and in Miami’s climate, water inside the roof decking turns into mold and rot faster than you’d think. If you’re seeing water stains on a ceiling or wall, call Mercer Roofing Co Miami at (850) 753-2996. We’ll send a technician whose name and photo you’ll have before they knock, and you’ll get a written price before any work starts.

Key Takeaways

• Flashing repair in Miami costs $250 – $650 for most single-location fixes; full replacement of multiple flashings runs $800 – $1,600.

• You get a photo and name of your technician before arrival, plus a written price before any work begins.
• Every flashing repair carries a 365-day written guarantee. If it fails within a year, we fix it at no charge.

When You Need Flashing Repair

Most Miami homeowners don’t think about flashing until water shows up where it shouldn’t be. Here are the signs we see most often in neighborhoods across the city, from Little Havana to Morningside.

• Water stains on ceilings or upper walls. Brown or copper-colored rings near exterior walls, chimneys, or skylights almost always trace back to failed flashing, not the shingles themselves. In coral-built homes in Coconut Grove, stains near a chimney chase are a flashing problem more often than a roof deck problem.
• Wet spots around skylights after a downpour. Miami’s afternoon thunderstorms are relentless. If you see water beading or streaks below a skylight after one of them, the skylight flashing has likely lifted or separated. Left alone, that leak grows and destroys drywall.
• Visible rust or corrosion on metal flashing. Salt air accelerates metal breakdown. Homes near Biscayne Bay, in neighborhoods like Edgewater and Brickell, see flashing corrode years earlier than homes further inland like Westchester. Rusted flashing is failed flashing.
• Lifting or peeling flashing edges. After a wind event or just years of thermal expansion, flashing pulls away from the roof surface. If you can see a gap or raised edge from the ground, water has already found it.
• Granules in gutters near walls or valleys. When flashing fails, water runs under shingles and breaks down the shingle base. Granules end up in your gutter, and the shingle itself starts to fail from below. In historic districts like Shenandoah and Coral Gate with older structures, this pattern is common.
• Damp or musty rooms on an upper floor. A persistent musty smell that doesn’t improve with cleaning often means water has been entering through a flashing seam for weeks. By the time you smell it, the decking underneath is likely wet.

If any of this sounds familiar, don’t wait. Miami’s rainy season from May through October doesn’t give leaky flashing a break. Call (850) 753-2996 and get on the schedule.

Our Flashing Repair Process

You’ll know exactly what’s happening on your roof before it happens. Here’s how a flashing repair with Mercer Roofing Co Miami works.

1. Call us. A live person answers 24 hours a day, seven days a week. No voicemail, no automated phone tree. You’ll describe what you’re seeing, and we’ll set a time for a technician to come look. The name and photo of your technician are sent to you before they arrive.
2. Badge at the door. When your technician arrives, they’ll present a photo ID badge. They arrive in a clean, marked uniform and identify themselves by name. If the person at your door doesn’t match the photo you were sent, don’t open the door. That’s the Threshold Standard, and every Mercer Roofing Co Miami visit follows it.
3. On-site inspection. The technician examines the flashing in question from the roof surface, looks at the surrounding decking and underlayment condition, and traces the water path. In many Miami homes, especially newer construction in Doral and Kendall, the problem is one failed penetration flashing. On older homes in the Upper Eastside or Allapattah, the issue can be several flashings that need re-sealing.
4. Written price before any work starts. You get a detailed, written estimate that covers the work, the materials, and the total price. You look it over, you approve it, and only then does work begin. There is never a surprise on the invoice.
5. The repair. We remove the failed flashing, inspect the decking underneath, replace any wood that’s beyond saving, reseal the area, and install new flashing. We use high-quality metal flashing and sealants rated for South Florida’s heat and rain. We work with manufacturer-recognized systems from brands including IKO, Atlas, and Tamko.
6. Written guarantee in hand. Every flashing repair is covered in writing for 365 days. If the repair fails at any point in that year, we return and fix it at no charge. That guarantee does not require a phone call full of negotiation. It’s sitting in writing before we leave your home.

Flashing Repair Pricing in Miami

Here’s what you can expect to pay for flashing repair in Miami, based on what we see across the city in 2025 and into 2026, alongside our How Much Does Roof Repair Cost? (2026 Price Guide) - Miami, FL. These are honest ranges, not bait prices.

Typical Flashing Repair Costs

Repair Type	Typical Range	Notes
Single flashing repair (one chimney, wall, or skylight)	$250 – $650	Most common job. Includes removal of old flashing, new flashing, sealant, and labor.
Multiple flashing repair (2 – 4 locations)	$600 – $1,200	Common on older homes where several seams fail at once.
Full flashing replacement (all penetrations)	$800 – $1,600	Typically done when multiple leaks have occurred or during a full Roof Repair in Miami.
Decking replacement (if rot is found)	$150 – $400 per sheet	Included in the written estimate if needed, never sprung on you later.
Skylight flashing and reseal	$400 – $900	Includes lifting, inspecting the skylight frame, and resealing the curb.

What Affects the Price

• Roof pitch and height. A steep roof on a three-story home in Coconut Grove takes longer and requires more safety equipment than a low-slope roof on a single-story rambler in Westchester.
• Access to the flashing. Chimneys, skylights, and wall abutments are the most common locations. Flashing tucked behind a stucco wall or on a second story adds labor time.
• Age of the roof. Older roofs often have brittle decking that needs more care during removal. If you have an older roof and the flashing is failing, the decking underneath may need replacement too.
• Number of flashings. One bad flashing is common. Four bad flashings means the whole system was probably installed with shortcuts.
• Material choice. Standard aluminum flashing is the most common and holds up well. Galvanized steel costs a bit more. Copper flashing, which some historic Morningside and Coral Way homes prefer for aesthetic reasons, costs significantly more.

Every estimate is free and comes in writing. There’s no obligation, and you’ll never be asked to approve work without seeing the full price first. Call (850) 753-2996 to schedule an inspection.

Why Miami Homeowners Choose Mercer Roofing Co Miami for Flashing Repair

The Stranger-at-the-Door Problem, Solved

You let a roofing technician into your home. That means you let a stranger into your home. Most roofing companies don’t treat that as a problem worth solving. We do. Before a Mercer Roofing Co Miami technician arrives, you get their name and photo. When they knock, they show a photo ID badge. They wear a clean, marked uniform. You’re never guessing who’s at your door.

The Threshold Standard

Mercer Roofing Co Miami is part of the Threshold Group family, founded in 2000. Every location, including this one, is independently owned and operated, and each one is contractually held to the Threshold Verified standard. That means every technician is background-checked, identity-verified, and dispatched under a quality framework that never gets skipped. You won’t find a subcontracted crew of unknown people on your roof. The person you’re told is coming is the person who shows up.

The 365-Day Done Right Promise

Every flashing repair comes with a written guarantee that covers the work for 365 days. If the repair fails in that year, we come back and do it right at no charge. That guarantee is included with every job, not sold as an add-on, and not conditional on you keeping a receipt in a folder somewhere. It’s in writing, every time.

Written Pricing, Every Time

You’ll get a written price before any work starts. No verbal estimates that change when the invoice arrives. No “while we’re up there” add-ons. The price you approve is the price you pay.

FAQs – Flashing Repair

How long does flashing repair take?

Most single-location flashing repairs in Miami take between one and three hours, and the majority are completed the same day. If decking replacement is needed, the job may extend to a full day. You’ll get a time estimate in writing before work begins. Call (850) 753-2996 for a free estimate.

Is it cheaper to repair flashing or replace the roof?

Flashing repair is significantly cheaper than a full Roof Repair or replacement, with most repairs in Miami running $250 to $650 versus $8,000 to $16,000 for a new roof. If the flashing failure is caught early and the roof decking is still sound, repair is almost always the right financial call. If flashing failures are recurring in multiple places and the roof is past its expected life, replacement may be the better long-term option. We’ll tell you honestly which one makes sense for your roof, not whichever one makes us more money.

Can you come out today to fix my flashing?

In most cases, yes. We offer same-day and next-day flashing repair in Miami, and a live person answers the phone 24/7 to get you on the schedule. Whether it’s a leak discovered before a storm hits or an active leak that started this morning, call (850) 753-2996 and we’ll get someone out as quickly as possible.

What happens if the flashing repair fails?

If your flashing repair fails within 365 days of the work being completed, we will return and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s written into every repair we do. You won’t be asked to pay for a second visit.

Do you work on all types of flashing?

Yes. We repair and replace chimney flashing, wall flashing, skylight flashing, valley flashing, and pipe boot flashing, including Flat Roof Patch work where needed. We work with standard aluminum and galvanized steel, and can match specific aesthetic needs for homes with more distinctive designs. We use materials from manufacturer-recognized brands including IKO, Atlas, and Tamko.

What Flashing Failure Looks Like in Miami Specifically

Miami’s climate isn’t gentle on roofing materials. Three specific factors make flashing repair here different from, say, inland Florida or the northern states.

• Heavy afternoon thunderstorms. Miami gets intense, short-duration rain that dumps inches of water in under an hour. Failed flashing means water enters the roof system during the worst possible moment: when the water is coming down hardest. Small gaps in flashing that would stay dry in a light-rain city get flooded in Miami.
• Salt air. Homes near Biscayne Bay in neighborhoods like Brickell, Edgewater, and Morningside deal with salt corrosion on metal flashing. Flashing that would last 20 years in cut-stone or stucco homes inland may start to show rust and pitting in 10 to 15 years near the water. If your home is within a mile of the bay, have your flashing inspected as part of any roof maintenance you do.
• Hurricane-driven wind and rain. Even a near-miss from a tropical system can lift flashing edges. After any named storm or serious wind event, it’s worth doing a visual check of the flashing around chimneys and walls. What looks like a small lift now becomes a leak in the next heavy rain.

Working With Insurance on Flashing Repair

If flashing failure has led to water damage inside your home, our Leak Repair service may be covered by your homeowner’s insurance policy. We recommend documenting any visible damage with photos before cleanup begins, and calling your insurer as soon as possible. We can give you an honest assessment of what the repair involves and a written estimate to share with your adjuster. While we don’t negotiate directly with insurance companies on your behalf, many of our customers in Miami use our written estimates to support their claim. We’ll give you what you need in writing, every time.
