Roof Leak Repair in Marathon, Done by a Local Crew

Weatherproof Roofing Inc has been repairing roofs since 1997, and Marathon is one of the communities we know block by block. Roof Leak Repair in Marathon is not the same job as it is on the mainland. Salt spray eats fasteners and flashing, hurricane-season wind-driven rain pushes water sideways through pipe boots, and the intense UV on flat and low-slope roofs cooks sealant until it cracks. We work on the shingle and tile roofs around Sombrero Beach, the metal and membrane roofs along Overseas Highway, and the older flat-roof homes on the bayside that have been patched three times by someone else. Our technicians carry roofing nail guns, pry bars, moisture meters and inspection cameras so we can open a suspect area, find the actual entry point, and close it the same day. If you need roof flashing repair, pipe boot repair or a full underlayment replacement, we handle it with Florida Building Code-compliant materials and a written workmanship warranty.

Marathon sits in the middle of the Florida Keys, where the marine layer keeps roofs wet with salt and humidity most of the year. That combination destroys roof cement, caulk and butyl tape faster than anywhere on the mainland. We serve this city because the demand is real and the local knowledge matters: which streets flood after a tropical system, which condo buildings have TPO membrane roofs past their service life, and which tile roofs have underlayment that has already failed under the tile. Homeowners and property managers here need a roofer who can get on the roof the same day, not in three weeks.

Who we serve in Marathon

Two very different jobs. One local crew.

For homes

Residential Roof Leak Repair in Marathon

Most of our Marathon work is on homes: canal-front houses in Key Colony Beach, stilt homes near Sombrero Beach, and older concrete-block houses along the Overseas Highway corridor. The common thread is salt air and sun. Roofs here age faster than on the mainland, and a small leak can turn into a mold problem in a matter of weeks. We treat every home like it is our own, which means we find the actual source, fix it with materials that will last in the Keys, and clean up before we leave.

Emergency leak response for homes

When water is dripping into your living room in Marathon, we respond fast. We tarp the roof if needed, stop the intrusion, and schedule the permanent repair. Most emergency calls get a same-day response, and we document everything for your insurance.

Pipe boot and flashing repair

These two items cause most of the leaks we see on Marathon homes. We replace failed pipe boots with UV-stable collars and install new corrosion-resistant flashing at wall intersections. It is a small repair that prevents big damage.

Tile and shingle roof repair

We repair tile and shingle roofs without replacing the whole roof. If the underlayment under your tile has failed, we lift the tile, replace the underlayment, and reset it. For shingle roofs, we match the existing product and reseal the surrounding field.

Flat roof leak repair for homes

Many Marathon homes have flat or low-slope roofs over garages, lanais and additions. We repair TPO and EPDM membrane with heat-welded patches and fix drainage issues so water does not pool and find the next weak spot.

  • Same-day emergency response for active leaks in Marathon, seven days a week.
  • Written estimate before work begins, with no hidden charges for the inspection.
  • Five-year workmanship warranty on repairs, plus manufacturer warranties on materials.

For businesses

Commercial Roof Leak Repair in Marathon

A roof leak at a Marathon business is not just a maintenance issue. It can shut down a kitchen, damage inventory, or force you to close a rental unit during peak season. We work with property managers, restaurant owners, marina operators and retail businesses along the Overseas Highway corridor. Our commercial crews are used to working around business hours, coordinating with tenants, and documenting everything for insurance and property records. If you need a commercial roof leak repair in Marathon that will not disrupt your operation, we can schedule the work around your needs.

  • Restaurants and bars
  • Marinas and boatyards
  • Retail and grocery
  • Hotels and vacation rentals
  • Property management
Work around business hours

We schedule commercial repairs early in the morning or after closing so your business stays open. For active leaks, we tarp first and do the permanent repair on your timeline. No surprise shutdowns.

Flat and low-slope roof expertise

Most Marathon commercial buildings have flat or low-slope roofs. We repair TPO and EPDM membrane with heat-welded patches and proper seam sealant. We also fix drainage issues that cause standing water and repeat leaks.

Documentation for insurance and records

We photograph the damage and the repair, and provide a written report you can give your insurer or property owner. That documentation protects you at claim time and helps you plan future roof capital expenses.

Preventive maintenance programs

We offer scheduled inspections for commercial properties in Marathon. We check flashing, seams, drains and penetrations before hurricane season, fix small issues, and give you a written condition report so you can budget for future work.

Emergency Roof Leak Repair in Marathon

Emergency Roof Leak Repair in Marathon

When a storm rolls through Marathon, emergency roof leak repair in Marathon becomes the call that saves ceilings, drywall, and peace of mind. Our crews know the Keys' wind-driven rain and salt air punish roofs fast, especially in neighborhoods like Sombrero Beach and Key Colony Beach. We mobilize quickly, locate the intrusion, and stop water from spreading before it ruins your island home.

Storm Damage Triage Process

We start with a rapid attic-to-ridge inspection to trace active water paths. In Marathon's older Conch-style homes, wind-lifted shingles and failed pipe boots are common culprits. We document every breach with photos, then prioritize temporary seals so your family stays dry while permanent repairs are scheduled.

Marathon Building Stock Challenges

From 1950s block homes on Grassy Key to modern stilt houses off Overseas Highway, each roof type leaks differently. Concrete tile, metal, and asphalt shingle all react to salt spray and 150-mph gusts. We match repair methods to your specific roof assembly, not a one-size-fits-all patch.

Rapid Response Across Marathon

Our local team is stationed to reach Coco Plum, Little Venice, and the Marathon Marina area within hours, not days. We carry tarps, sealants, and replacement materials on every truck. That means fewer callbacks and a faster return to normal after tropical systems pass.

  • 24/7 emergency dispatch for active leaks in Marathon
  • Infrared moisture scans to find hidden ceiling saturation
  • Same-day temporary sealing to stop interior damage
  • Written repair scope with photos for insurance claims

Roof Flashing Repair 02
Roof Flashing Repair in Marathon

Roof Flashing Repair in Marathon

Roof flashing repair in Marathon is critical because flashing is the first line of defense at every wall, valley, and penetration. Salt-laden air and intense UV degrade sealants and metal faster here than on the mainland. Whether your home sits in Sombrero Beach or near Vaca Cut, we restore flashing so water never finds a path inside.

Common Flashing Failure Points

In Marathon, step flashing along dormers and sidewalls often corrodes from salt exposure. Chimney counter-flashing and valley metal also loosen after repeated wind events. We inspect each transition, reseal lifted edges, and replace rusted sections with marine-grade materials suited to coastal conditions.

Coastal Material Selection

Standard galvanized flashing can fail within a few years near the ocean. We use aluminum, copper, or high-grade stainless depending on your roof type and proximity to the water. For tile roofs in Key Colony Beach, we custom-fabricate profiles that match existing courses and maintain proper drainage.

Preventing Future Intrusions

After repairs, we apply UV-stable sealants and verify that every lap directs water away from seams. Our technicians also check fasteners for backing out, a frequent issue on metal roofs in Marathon's heat. This proactive approach extends flashing life and protects your interior through hurricane season.

  • Replace corroded step, counter, and valley flashing
  • Fabricate custom profiles for tile and metal roofs
  • Apply marine-grade sealants rated for salt air
  • Verify proper overlap and drainage at all transitions

Pipe Boot Repair 03
Pipe Boot Repair in Marathon

Pipe Boot Repair in Marathon

Pipe boot repair in Marathon addresses one of the most overlooked leak sources on any roof. The rubber collar around plumbing vents cracks under relentless sun and salt wind, letting water drip straight into attics and ceilings. We replace worn boots with UV-resistant, Florida-approved components built to handle Keys weather.

Why Pipe Boots Fail Here

Marathon's intense UV index breaks down rubber collars in as little as five years. Add salt air and 100-degree roof temperatures, and the material becomes brittle and tears. We see this constantly on homes in Coco Plum and Little Venice, where a tiny crack leads to stained ceilings below.

Correct Replacement Methods

We remove the old boot, clean the pipe surface, and install a new collar with a reinforced base. For tile roofs, we carefully lift surrounding tiles to slide the boot into place, then reseat them. Proper alignment prevents future lifting and ensures a watertight seal around the vent.

Preventive Maintenance Plans

Because pipe boots degrade predictably, we offer annual inspections for Marathon homeowners. Catching a cracked collar early avoids interior repairs and mold remediation. Our maintenance visits include checking all vent penetrations, resealing as needed, and documenting conditions for your records.

  • Replace cracked rubber boots with UV-stable collars
  • Reseat surrounding tiles or shingles for a tight fit
  • Seal base plates with coastal-grade urethane
  • Offer annual inspection to catch early deterioration

Flat Roof Leak Repair 04
Flat Roof Leak Repair in Marathon

Flat Roof Leak Repair in Marathon

Flat roof leak repair in Marathon requires understanding how low-slope systems handle standing water, salt air, and blistering heat. Many commercial buildings and modern homes near Overseas Highway use modified bitumen or TPO membranes that fail at seams and drains. We locate the source and restore the membrane so water stops finding its way inside.

Membrane Seam Failures

Heat cycling causes seams to open on flat roofs throughout Marathon. We inspect every lap, edge, and penetration, then clean and re-weld or patch with compatible membrane material. For TPO systems, we use hot-air welding to create a monolithic bond that resists future separation.

Drainage and Ponding Issues

Standing water is the enemy of any flat roof. In Marathon's heavy summer rains, clogged drains and improper slopes lead to ponding that seeps through tiny pinholes. We clear drainage paths, add crickets where needed, and reinforce low spots to keep water moving off the roof.

Coating and Restoration Options

When the membrane is too far gone for patches, we apply reflective acrylic or silicone coatings. These extend roof life, reduce cooling costs, and add a seamless layer of protection against salt-laden humidity. Many Marathon property owners choose this route to defer full replacement.

  • Locate leaks with electronic moisture detection
  • Re-weld TPO and modified bitumen seams
  • Clear drains and correct ponding areas
  • Apply reflective coatings to extend membrane life

Missing Shingle Roof Repair 05
Missing Shingle Roof Repair in Marathon

Missing Shingle Roof Repair in Marathon

Missing shingle roof repair in Marathon is urgent after every tropical storm or nor'easter. When shingles tear away, the underlayment and deck are exposed to driving rain and salt spray. We respond fast to replace missing tabs, matching color and profile so your roof looks whole and performs as intended.

Storm Damage Assessment

After a blow, we inspect the entire roof plane, not just the obvious gap. Wind can lift shingles several courses away, leaving hidden breaches. In Marathon neighborhoods like Sombrero Beach, we map every missing or creased shingle, then order matching material for a seamless repair.

Matching Shingle Profiles

Discontinued shingles are a common problem on older Marathon homes. We keep a network of suppliers and salvage sources to find close matches, or we blend new shingles into less visible areas. The goal is a repair that protects the roof and maintains curb appeal.

Preventing Future Tear-Offs

After replacing missing shingles, we check fastening patterns and re-nail lifted areas. For roofs nearing the end of their life, we discuss upgrade options like impact-rated shingles that meet Florida building codes. This reduces the chance of repeat damage in the next storm.

  • Replace missing shingles with color-matched material
  • Re-nail lifted courses to prevent further loss
  • Inspect underlayment for hidden storm damage
  • Recommend impact-rated shingles for future storms
Book Missing Shingle Roof Repair →
Tile Roof Leak Repair 06
Tile Roof Leak Repair in Marathon

Tile Roof Leak Repair in Marathon

Tile roof leak repair in Marathon demands a delicate touch because the leak is rarely the tile itself. Cracked or slipped tiles expose the underlayment, which then fails under salt air and rain. We carefully lift tiles, repair the underlying membrane, and reset the tiles so your roof retains its beauty and weather-tight integrity.

Underlayment Failures

Most tile roof leaks in Marathon trace back to deteriorated underlayment, not broken tiles. After 15 to 20 years, the felt or synthetic layer cracks and lets water through. We remove affected tiles, replace the underlayment, and reinstall tiles with proper fasteners and sealant.

Cracked and Slipped Tiles

Foot traffic, wind, and thermal expansion cause tiles to crack or slip out of place. On historic homes in Key Colony Beach, we source matching tiles or carefully repair existing ones. Each tile is secured and sealed to prevent future movement and water intrusion.

Valley and Flashing Details

Tile roofs rely on open valleys and proper flashing to shed water. In Marathon, these details often clog with debris or corrode from salt. We clean valleys, replace damaged flashing, and ensure water flows freely to gutters or ground, eliminating the pooling that leads to leaks.

  • Lift and reset tiles to access underlayment
  • Replace failed underlayment with synthetic membrane
  • Source matching tiles for historic Marathon homes
  • Clear valleys and repair corroded flashing

Chimney Roof Leak Repair 07
Chimney Roof Leak Repair in Marathon

Chimney Roof Leak Repair in Marathon

Chimney roof leak repair in Marathon focuses on the intersection where masonry meets roofing, a spot notorious for hidden water entry. Salt air erodes mortar and flashing, while wind-driven rain pushes past deteriorated seals. We rebuild that critical junction so your chimney stops channeling water into your attic and living spaces.

Flashing and Counter-Flashing

The flashing around a chimney is the first component to fail. In Marathon, we see rusted step flashing and lifted counter-flashing on many older homes. We remove damaged metal, install new copper or aluminum flashing, and seal it with marine-grade caulk for a lasting barrier.

Masonry and Mortar Repairs

Cracked mortar joints and spalling brick absorb water like a sponge. We repoint mortar with a salt-resistant mix and apply a breathable water repellent. This stops the freeze-thaw and salt crystallization that slowly destroy chimneys in coastal Marathon.

Crown and Cap Issues

A cracked chimney crown lets water run down the interior flue. We repair or replace crowns with flexible, weather-resistant materials. Adding a stainless steel cap further deflects rain and keeps out birds and debris, a smart upgrade for any Marathon home.

  • Replace rusted step and counter-flashing
  • Repoint mortar with salt-resistant mix
  • Repair or replace cracked chimney crowns
  • Install stainless steel caps for rain protection

Skylight Leak Repair 08
Skylight Leak Repair in Marathon

Skylight Leak Repair in Marathon

Skylight leak repair in Marathon tackles a common problem in both older and newer homes. The seal around the skylight frame degrades under UV and salt air, allowing water to seep in during heavy rains. We diagnose the exact failure point and restore the weather seal so you can enjoy natural light without the drip.

Seal and Gasket Replacement

The rubber gaskets and sealants around skylights dry out and crack in Marathon's climate. We remove the old seal, clean the frame and glass, and apply new UV-stable sealant. For older units, we replace the entire gasket kit to ensure a watertight fit.

Flashing and Curb Issues

Skylight curbs and flashing are frequent leak sources, especially when installed on tile or metal roofs. We inspect the curb for rot, reseal flashing layers, and ensure proper overlap. In neighborhoods like Little Venice, we often find flashing that was never correctly integrated with the roof.

Condensation vs. Leak

Not every drip is a leak. Marathon's humidity can cause condensation inside the skylight well. We check ventilation and thermal breaks to rule out condensation, then focus on true water intrusion. This prevents unnecessary repairs and solves the real problem.

  • Replace cracked gaskets and UV-degraded sealant
  • Reseal flashing and repair rotted curbs
  • Distinguish condensation from active leaks
  • Verify proper drainage around skylight frame

Emergency Roof Tarping 09
Emergency Roof Tarping in Marathon

Emergency Roof Tarping in Marathon

Emergency roof tarping in Marathon is the first line of defense after a storm tears open your roof. Before permanent repairs can begin, a securely installed tarp prevents further water damage to your home's interior. Our crews respond quickly across the Keys, securing vulnerable areas and protecting your property from additional loss.

Rapid Deployment After Storms

When a hurricane or severe squall hits Marathon, we stage crews to respond as soon as winds subside. We prioritize homes with active water intrusion, especially in low-lying areas like Coco Plum. Our trucks carry heavy-duty tarps and fastening systems ready for immediate installation.

Proper Tarp Installation

A tarp is only effective if it's installed correctly. We anchor it over the ridge and secure edges with battens and screws, not just bricks or ropes. This prevents wind from lifting the tarp and exposing your roof again. In Marathon's gusty conditions, proper anchoring is non-negotiable.

Insurance Documentation

We photograph the damage before and after tarping, providing clear evidence for your insurance claim. Our reports include date, time, and materials used, which helps adjusters process your claim faster. This documentation is especially valuable for Marathon homeowners dealing with storm losses.

  • 24/7 emergency tarping for storm-damaged roofs
  • Secure tarps with battens and mechanical fasteners
  • Photograph damage for insurance documentation
  • Coordinate with adjusters for smooth claims

Roof Underlayment Repair 10
Roof Underlayment Repair in Marathon

Roof Underlayment Repair in Marathon

Roof underlayment repair in Marathon is often the hidden fix that stops persistent leaks. When the protective layer beneath shingles or tiles fails, water seeps through to the deck and ceiling. We remove the roofing above, replace the damaged underlayment, and restore the system so your roof sheds water reliably again.

Signs of Underlayment Failure

Stained ceilings, attic moisture, and widespread leaks after rain often point to underlayment failure. In Marathon's older homes, original felt paper has likely deteriorated. We inspect from the attic and roof surface to confirm the diagnosis before recommending repair.

Synthetic vs. Felt Options

We replace worn felt with synthetic underlayment, which resists tearing and UV damage far better. For tile roofs in Key Colony Beach, we use high-temperature membranes that won't degrade under the hot tiles. This upgrade adds years of protection against salt air and rain.

Preventing Deck Rot

Failed underlayment lets water reach the wood deck, causing rot and structural weakness. We inspect for soft spots and replace damaged plywood before installing new underlayment. This comprehensive approach ensures your Marathon roof is solid from the deck up.

  • Remove roofing to access failed underlayment
  • Install synthetic or high-temp membrane
  • Replace rotted decking before new installation
  • Verify proper overlap and fastening for drainage

How We Execute Roof Leak Repair in Marathon

Roof leak repair in Marathon runs on a different clock than the mainland. Salt air and humidity mean we use stainless or hot-dipped galvanized fasteners, and we seal every penetration with products rated for coastal expo

Salt air corrodes flashing and fasteners

Standard galvanized flashing and nails fail in a few years on Marathon roofs. The corrosion opens gaps at wall intersections and valleys, and water gets in behind the flashing.

How we help: We use corrosion-resistant fasteners and flashing on every repair, and we seal the edges with a coastal-rated sealant. On roofs within a few blocks of the water, we upgrade to stainless where it matters most.

Hurricane-season wind-driven rain

Water gets pushed sideways through pipe boots, skylight curbs and ridge vents during a tropical system. Leaks that never show up in a normal rain suddenly appear.

How we help: We inspect and reseal every penetration before hurricane season, and we use Miami-Dade NOA-approved products on repairs. If a storm is coming, we can tarp the roof and come back for the permanent fix after the weather clears.

Flat roofs with poor drainage

Standing water on flat and low-slope Marathon roofs finds every seam and puncture. Over time, the membrane separates and the leak shows up inside the building.

How we help: We locate the low spots with a moisture meter, repair the membrane with heat-welded patches, and where drainage is the real problem, we recommend adding tapered insulation or a new drain to move water off the roof.

Recent Roof Leak Repair Results in Marathon

These are real jobs we have done in and around Marathon. They show the kind of leaks we find here and how we fix them. Names and exact addresses are withheld, but the details are accurate.

01 Sombrero Beach area

The problem

A homeowner near Sombrero Beach had a ceiling stain that grew every time it rained from the southeast. Two other roofers had patched the shingles and the leak came back.

What we did

We used a moisture meter and inspection camera to trace the water to a failed pipe boot on the back slope, not the shingles. We replaced the boot with a UV-stable EPDM collar, sealed the base with butyl tape and roof cement, and replaced the surrounding shingles that had been damaged by the previous patches.

The result

The leak stopped immediately. We did a water test before leaving and the ceiling stayed dry through the next three rainstorms. Total job time was about four hours.

02 Overseas Highway corridor

The problem

A small restaurant on Overseas Highway had water dripping onto a prep area during a summer storm. The building had a flat TPO membrane roof that was about 12 years old.

What we did

We found a separated seam near a rooftop HVAC curb. We cleaned the membrane, heat-welded a patch over the seam, and resealed the curb flashing with a coastal-rated sealant. We also cleared a blocked drain that was causing standing water.

The result

The prep area stayed dry through the rest of hurricane season. The repair cost a fraction of a full membrane replacement and bought the owner several more years of roof life.

03 Key Colony Beach

The problem

A canal-front home in Key Colony Beach had a leak that showed up in the garage, far from any visible roof damage. The roof was a low-slope EPDM rubber membrane.

What we did

We traced the leak to a puncture in the membrane under a foot traffic path, likely from a previous repair crew. We cleaned the area, applied a heat-welded EPDM patch, and sealed the edges with Titebond membrane adhesive. We also added a walkway pad to prevent future punctures.

The result

No leaks after the repair. The homeowner has since referred two neighbors to us for similar flat roof leak repair in Marathon.

Marathon problem patterns

Common Roof Leak Problems in Marathon

Marathon roofs face a specific set of enemies: salt air, intense UV, hurricane winds and a marine layer that keeps everything damp. These conditions drive the same problems over and over. Knowing what to look for helps you catch a leak before it becomes a major repair.

01

Pipe boot failure on shingle and tile roofs

Why it happens: The rubber collar around plumbing vents breaks down fast in the Keys. UV and salt air crack the rubber within 10 to 15 years, and the next hard rain sends water down the pipe chase. It is the single most common leak we find in Marathon.

Our approach: We replace the failed boot with a UV-stable EPDM collar and seal the base with butyl tape and roof cement. We also check every other penetration on the roof while we are there, so you do not get a second leak next month.

02

Flashing corrosion at wall intersections

Why it happens: Salt air eats galvanized flashing. The metal thins, pinholes form, and water gets behind the flashing at wall tie-ins and valleys. On older Marathon homes, the original flashing may be completely rusted through.

Our approach: We remove the failed flashing, treat the substrate, and install new corrosion-resistant flashing sealed with a coastal-rated product. We use stainless fasteners in high-exposure areas near the water.

03

Tile roof underlayment failure

Why it happens: Tile roofs in Marathon are 15 to 25 years old on many homes. The underlayment under the tile dries out and tears, and water travels sideways under the tile before it shows up inside. The tile itself looks fine, which is why homeowners are often surprised.

Our approach: We lift the tile in the affected area, replace the failed underlayment with a new synthetic product, and reset the tile. If the underlayment is failing across the whole roof, we give you an honest assessment of repair versus replacement.

04

Flat roof seam separation and punctures

Why it happens: Flat and low-slope roofs on Marathon homes and commercial buildings take a beating from the sun. The membrane expands and contracts, seams separate, and foot traffic from HVAC techs can puncture the surface. Standing water makes every weak point worse.

Our approach: We locate the leak with a moisture meter, repair the membrane with heat-welded patches, and seal the edges with membrane adhesive. Where drainage is the root problem, we recommend a fix so the leak does not come back.

Marathon through the year

How Seasons Affect Roof Leak Repair in Marathon

Marathon does not have a typical four-season climate, but the year still has distinct patterns that affect your roof. Here is what to expect and what to do each season.

Spring

Spring brings warm, humid air and the start of afternoon thunderstorms. Small leaks from winter wind damage start showing up as ceiling stains. It is the best time to get ahead of hurricane season.

Tip: Schedule a roof inspection before June. We check flashing, pipe boots and shingles and fix small issues while the weather is calm.

Summer

Summer is hurricane season in Marathon. Wind-driven rain finds every weak point, and the heat and UV are at their peak. Emergency tarping and leak calls spike during tropical systems.

Tip: If a storm is forecast, clear your gutters and check for loose shingles. If you get a leak, call us immediately. We run emergency tarping 24/7 during storms.

Fall

Fall is still hurricane season, and the first cold fronts can bring strong northwest winds. Roofs that survived summer may develop new leaks as the wind direction changes and finds different weak spots.

Tip: After any named storm or strong cold front, walk your yard and look for shingle pieces. Call us for a post-storm inspection if you see any.

Winter

Winter in Marathon is mild, but it is the dry season. Leaks are less obvious because there is less rain. This is the best time for permanent repairs and underlayment replacement.

Tip: Use the dry months to schedule non-emergency repairs. We can get to you faster, and the materials cure properly in moderate temperatures.

We know the route

Navigating Marathon: Landmarks We Use

Marathon runs roughly from the Seven Mile Bridge to the south and the Long Key area to the north, with Overseas Highway as the spine. When you call, we orient by landmarks you already know. That helps us get the right truck to the right side of the island without wasting time on directions.

Seven Mile Bridge

The bridge is the southern anchor of Marathon. If your address is south of the bridge approach, we know you are on the ocean side and route accordingly.

Sombrero Beach

A well-known beach on the ocean side. Addresses near Sombrero Beach Road help us identify the surrounding residential streets quickly and avoid the Overseas Highway backup.

Marathon Airport (Florida Keys Marathon International Airport)

The airport sits mid-island and is a useful midpoint reference. If you are near the airport, we know you are close to the Overseas Highway corridor and can plan access from either direction.

Boot Key Harbor

The harbor and mooring field are on the bayside. Addresses near Boot Key Harbor tell us to approach from the bay side, which matters when the highway is congested.

Most residential roof leak repairs in Marathon run $350 to $1,200 in 2026, depending on roof type, leak location and access. A simple pipe boot replacement is on the low end. Tile roof repairs and flat membrane patches are higher. We give you a written estimate before we start, and the inspection is free if you hire us for the repair.

We typically respond within 30 to 60 minutes for emergency calls in Marathon, and we answer the phone 24/7. If a storm is active, we prioritize active leaks and tarping. Call (833) 356-1017 and we will give you a realistic arrival time based on where our crews are.

Yes. We use moisture meters and inspection cameras to trace the water to its source before we open anything. Most leaks come from a small number of culprits: pipe boots, flashing, underlayment or membrane seams. We open only the area we need to, repair it, and water-test it before we leave.

We repair tile roofs. If the underlayment under a section of tile has failed, we lift the tile, replace the underlayment, and reset the tile. That is often far cheaper than a full replacement. If the whole roof is at the end of its life, we will tell you honestly and give you options.

Yes. We document storm damage with photos and a written report you can give your adjuster. We can tarp the roof to prevent further damage and then provide a repair estimate. We work with most major insurers and can answer questions about the repair scope during the claims process.
