Complete Metal Roofing Repair

A wet stain spreading across your bedroom ceiling during last week’s nor’easter isn’t just an inconvenience-it’s your metal roof telling you something specific failed, and on most Nassau County homes I inspect, the fix is a targeted repair costing $800-$2,400, not the $15,000-$30,000 full replacement some contractors will push. I’m Sam Qureshi, and over 21 years fixing metal roofs from Massapequa to Manhasset, I’ve learned that the biggest problem homeowners face isn’t the leak itself-it’s not knowing whether they’re looking at a simple fastener issue or a systemic failure that actually requires replacement.

Metal Roofing Repair Services in Nassau County, NY

TWI Roofing specializes in repairing metal roofs on homes and businesses across Nassau County, from standing seam systems on custom colonials to corrugated panels on commercial warehouses. We handle urgent situations-active leaks, storm damage, loose panels rattling in high wind-and we work on standing seam, exposed-fastener systems, metal shingles, and tile-look profiles.

Call us immediately at [phone number] if water is entering your home. We offer same-day response for emergency situations when weather permits, and we can often provide temporary protection within hours while scheduling permanent repairs.

Noticed a Leak or Damage? What to Do Right Now

Step 1: Stay Safe and Protect the Inside of Your Home

Do not climb onto a wet or storm-damaged metal roof yourself. Metal panels become extremely slippery when wet, and damaged systems can have loose panels or weakened fastening.

Place buckets or towels where water is entering. Move electronics, furniture, and valuables away from wet areas. If you can safely take photos or short videos of the leak location from inside your home-showing where water is dripping and any visible staining-those images help us diagnose faster and can support insurance claims later.

Step 2: Call a Metal Roofing Repair Specialist

Metal roofs leak and fail for completely different reasons than asphalt shingle roofs. A contractor who only works on shingles will miss critical details about seam design, fastener patterns, thermal expansion, and galvanic corrosion that define how metal systems perform.

Our team can often provide temporary protection quickly-tarping, emergency sealant, or fastener tightening-then schedule a thorough inspection and permanent repair once immediate water intrusion is controlled. You can call us directly or text photos of the problem area to start the conversation and help us prepare for the visit.

Common Metal Roof Problems We Repair in Nassau County

Leaks at Seams, Fasteners, and Penetrations

• Water seeping through panel seams or standing seam locks after driving rain, often due to capillary action when sealant or clip systems fail
• Backed-out or stripped fasteners on exposed-fastener systems, allowing water to track down screws into the roof deck
• Worn, cracked, or UV-degraded sealant around vents, skylights, chimneys, and pipe penetrations
• Improperly flashed transitions where metal meets walls, dormers, or sections with different roofing materials like asphalt or EPDM

Storm and Wind Damage

• Panels lifted, bent, or loosened by nor’easter winds exceeding 60 mph or passing hurricanes that test the fastening system beyond its design limits
• Wind-driven rain forcing water under panels and through normally protected laps when sustained gusts create negative pressure zones
• Debris and fallen branches denting panels, tearing seams, or damaging ridge caps and edge trim

Rust, Corrosion, and Aging Coatings

• Rust spots at cut edges, fastener holes, or areas where the factory coating was scratched during installation or maintenance
• Widespread chalking or fading finish that exposes bare metal to accelerated weathering and corrosion
• Salt-air corrosion on homes within two miles of the South Shore, bays, and marinas, especially on lower-grade steel or improperly maintained aluminum

Noise, Loose Panels, and Other Annoyances

• Rattling or banging sounds during high wind when panels, clips, or trim pieces are undersecured or thermal movement isn’t properly accommodated
• Oil-canning (visible waviness in flat panel areas) that’s usually cosmetic but can signal fastening or structural issues in severe cases
• Minor dents and cosmetic damage that homeowners want corrected for appearance or to prevent future corrosion at stress points

Our Metal Roof Repair Process

1. Initial Call and Triage

When you contact us, we ask targeted questions: Where is the leak showing inside? What does your roof look like-standing seam, screwed-down panels, metal shingles? When did the problem start-after a specific storm, or gradually over time? Is water actively entering, or are you seeing stains and want to prevent a leak?

Photos or videos from your phone help us prioritize urgency and bring the right materials and tools. If you’re experiencing active water intrusion and weather permits, we’ll discuss emergency temporary measures and schedule a visit as quickly as possible.

2. On-Roof Inspection and Diagnosis

A trained metal roofing technician inspects the roof surface, examining seams, fasteners, penetrations, flashings, and adjacent areas. We look for the obvious-visible holes, lifted panels, rust-through-and the subtle: fastener patterns that don’t match wind load requirements, sealant that’s lost adhesion but looks intact from below, or thermal-expansion issues causing seam separation.

We also inspect from inside when possible, checking attic spaces or ceiling cavities to trace the water path and rule out condensation problems that can mimic leaks on metal roofs. Our goal is finding the root cause, not just the visible drip or stain.

3. Clear Repair Options and Upfront Expectations

We explain what we found in plain language, showing you photos on our phone or tablet if helpful. On a 15-year-old standing seam roof in Merrick last month, the homeowner saw water in two bedrooms and assumed the entire roof was failing-our inspection revealed four loose clips on the west slope where a tree branch had scraped during a storm, leaving the rest of the system intact.

We outline different repair options when possible: a focused repair addressing the immediate problem, a more comprehensive repair if we see adjacent areas starting to fail, or a candid discussion about replacement if the roof is at the end of its life. You receive a written estimate or clearly explained pricing before we proceed.

4. Targeted, Code-Compliant Repairs

We repair or replace damaged panels, fasteners, sealants, and flashing using materials compatible with your existing system. That means matching metal type (steel with steel, aluminum with aluminum), gauge, and finish to avoid galvanic corrosion and aesthetic mismatches.

All work follows manufacturer installation guidelines and Nassau County building codes. For structural repairs or modifications affecting more than 25% of a roof section, we pull permits and schedule inspections as required. We seal carefully, fasten correctly, and clean up thoroughly so the roof is watertight and your property looks untouched except for the repair itself.

5. Follow-Up and Preventive Advice

For roofs with chronic issues or complex repairs, we can schedule follow-up inspections-typically 30-60 days after the initial work-to verify the repair is performing through rain cycles and temperature changes.

We offer straightforward maintenance advice for Nassau County metal roofs: clear debris from valleys and low-slope sections twice yearly, visually check fasteners and sealant around penetrations annually, and call for professional inspection after major storms or if you notice new stains, noise, or rust spots. We’ll flag areas that may need attention in the next few years so you can budget and plan instead of facing surprise failures.

Repair or Replace? How We Help You Decide

When a Repair Is Usually Enough

• Leaks are isolated to one or two clear problem areas-a failed penetration flashing, a seam damaged by debris-not spread across the entire roof
• Metal panels are generally solid, with only small spots of surface rust or minor dents that haven’t compromised structural integrity
• The roof is relatively young (under 20 years on most coated steel systems, under 30 on aluminum or higher-grade materials) and was installed reasonably well
• Previous installation meets basic standards, and problems are limited to maintenance items like sealant renewal or fastener adjustment

When Replacement Starts to Make More Sense

• Widespread corrosion, with thinning metal or rust holes appearing in multiple panels across large areas
• Frequent leaks in different locations, even after multiple repair attempts, indicating systemic installation or material failures
• Very old systems (30+ years on basic steel, 40+ on aluminum) that no longer meet current wind load or fastening standards for Nassau County’s coastal exposure
• Underlying deck damage, rot, or structural issues discovered during inspection that require extensive disassembly to address

No-Pressure Recommendations

Our goal is honest guidance. If your roof can be repaired and will give you another 10-15 years of service, we’ll tell you that and quote the repair. If we see a repair that will only last 2-3 years before the next failure, we’ll explain why replacement might be more cost-effective long-term.

We’re happy to provide both a repair quote and a replacement quote if you want to compare costs and expected lifespan side-by-side. The decision is yours-we simply give you the information to make it confidently.

Metal Roofs We Repair

Residential Metal Roofing

• Standing seam roofs on colonials, ranches, capes, and custom homes throughout Nassau County
• Metal shingle and tile-look systems (often installed to mimic slate or clay on historic properties)
• Metal porch roofs, bay window covers, and accent sections tied into asphalt or other primary roofing
• Attached garages, additions, sheds, and pool houses with corrugated or ribbed metal panels

Commercial and Multi-Unit Buildings

• Low-slope and pitched metal roofs on offices, warehouses, retail spaces, and industrial buildings
• Mixed roofing systems where metal sections transition to TPO, EPDM, or built-up roofs, requiring careful flashing and drainage coordination
• Preventive maintenance programs and emergency repairs for HOAs, condos, and co-ops with metal roofing components

Different Metals and Coatings

We work on steel roofs (Galvalume, galvanized, and various painted finishes) and aluminum systems, in gauges from 22 down to 29 and profiles ranging from traditional corrugated to modern architectural standing seam.

Coating type matters significantly. A basic polyester paint over Galvalume might show wear and rust at 15 years near the coast, while a Kynar 500 or similar high-performance finish often reaches 30+ years. We always match or use compatible materials and sealants to avoid galvanic corrosion-the electrochemical reaction that happens when dissimilar metals contact each other in the presence of water.

Local Expertise: Repairing Metal Roofs in Nassau County’s Climate

Dealing With Salt Air and Coastal Exposure

Homes within two miles of the South Shore, Great South Bay, or the various inlets and marinas see accelerated corrosion on unprotected cut edges, fasteners, and any area where coating has been compromised. I’ve traced more leaks to salt-accelerated fastener corrosion in coastal Oceanside and Island Park than anywhere else in Nassau County.

When we repair roofs in these areas, we treat and monitor corrosion-prone zones carefully, often recommending stainless steel fasteners or additional sealant on cut edges. In some cases, we suggest upgrades to more salt-resistant materials-switching from basic painted steel to aluminum or higher-grade coated steel-especially if we’re already replacing panels. We’ll also give you specific advice on periodic freshwater rinsing and visual checks to slow future rust.

Wind, Nor’easters, and Heavy Rain

Nassau County sits in a high-wind zone, with nor’easters regularly exceeding 50 mph sustained winds and gusts to 70+ mph. Metal roofs handle wind well when properly fastened, but older systems or those installed before current code requirements can experience panel lift and fastener failure.

When repairing wind damage, we don’t just replace the lifted panel-we evaluate and often reinforce the fastening pattern in that area, adding clips or fasteners to meet current uplift requirements. We pay extra attention to laps, seams, and edge details where wind-driven rain enters when sustained gusts create the pressure differentials that force water upward under normally weathertight joints. All repairs are done to meet or exceed Nassau County building codes and manufacturer wind-zone specifications.

What to Expect During and After Your Repair Visit

Timing and Disruption

Simple repairs-replacing sealant around a chimney, tightening loose fasteners, patching a small rust hole-often take 2-4 hours. More involved work like replacing damaged panels, reflashing a dormer, or addressing multiple problem areas might take a full day or require a return visit for final sealing after we verify the repair under the next rain.

Working on metal creates noise-footsteps sound louder, tools and materials clatter-but disruptions are usually limited to the immediate work area and the hours we’re actively on-site. We keep the site as clean as possible, using tarps to catch debris and removing all waste at the end of each day.

Homeowner Preparation

• Move parked cars away from the driveway and work area so we have clear access for ladders, material staging, and vehicle positioning
• Clear items from around the house perimeter where we’ll place ladders-planters, furniture, grills, and lawn decorations
• Point out any interior areas where you’ve seen leaks, stains, or moisture so we can inspect those spots from inside if needed
• Secure or inform us about pets that might be startled by roof activity or workers moving around the property

After-the-Repair Support

We provide written documentation of the work completed and materials used. Most repairs carry a workmanship warranty (typically 1-2 years depending on scope), separate from any manufacturer material warranties.

Call us if you notice new moisture, stains, or noise from the repaired area-sometimes water takes a complex path through roof layers and we need to trace further, or a secondary issue becomes apparent only after the primary leak is fixed. For older roofs or those in very exposed coastal locations, we can schedule periodic inspections (annually or after major storms) to catch developing problems before they cause interior damage.

Common Metal Roof Repair Costs in Nassau County

Costs vary based on roof height, access difficulty, specific materials required to match existing systems, and current metal pricing. These ranges reflect typical residential repairs in Nassau County as of 2024. We provide detailed estimates after inspection.

FAQs About Metal Roofing Repair in Nassau County, NY

Can you fix a leak in the middle of a storm?

In active storms with high winds or lightning, it’s not safe for anyone to be on a roof. Once conditions allow-usually when sustained winds drop below 25 mph and lightning has moved away-we can provide temporary protection like tarping or emergency sealant. We then return for permanent repairs once we can work safely and see the roof in dry conditions to verify the fix.

How much does metal roof repair usually cost?

Most repairs we complete fall between $800-$2,400, with simple sealant or fastener work on the lower end and multi-panel replacements or complex flashing repairs on the higher end. After a brief phone conversation describing your issue, we can often give you a rough range; precise pricing comes after on-site inspection when we see access, material requirements, and full scope.

Will you work on a metal roof another contractor installed?

Yes. We regularly service and repair metal roofs installed by other contractors, including systems that are 20-30+ years old where the original installer may no longer be in business. We inspect first to understand how the system was built and whether repairs are feasible. Any warranties we provide cover our repair work specifically; we cannot warranty or be responsible for the original installation quality beyond what we directly address.

Do you help with insurance claims for storm damage?

We document damage with photos and detailed notes, provide written repair estimates in the format insurers typically require, and communicate directly with adjusters when requested. Final coverage decisions rest with your insurance company based on your policy terms. We’ve worked with most major carriers on Nassau County claims and understand their inspection and documentation requirements.

How often should I have my metal roof inspected to avoid surprise leaks?

For metal roofs in good condition, visual checks from the ground after major storms and a professional inspection every 2-3 years is usually sufficient. If your roof is over 20 years old, in a very exposed coastal location, or surrounded by trees, annual inspections help catch sealant degradation, fastener backup, and early rust before they turn into active leaks. We also recommend inspections after any event that drops debris on the roof-fallen branches, nearby construction, or high-wind storms with sustained gusts over 60 mph.
