New Roof Passed Inspection But Still Leaks — Why It Happens

The Core Problem

You Have a Certificate of Completion — and a Wet Ceiling

The inspection stamp does not mean watertight. Here is why.

You watched the crew work for days. The county inspector came out, walked the roof, and signed off. A couple of months later, the first tropical storm of the season hits — and water is running down your living room wall. This is not as rare as it should be in South Florida, and it is not always the inspector’s fault.

A building inspection in Miami-Dade or Broward is a visual compliance check against the Florida Building Code (FBC) and the High-Velocity Hurricane Zone (HVHZ) provisions in FBC Chapter 44. The inspector verifies that materials match the Notice of Acceptance (NOA) or Florida Product Approval on file, that fastener patterns appear correct, and that underlayment was installed. What the inspector cannot do is re-lift every tile, pull every flashing, or apply hurricane-speed pressurized water to every transition point. That is not a criticism of inspectors — it is a structural limitation of a single post-install site visit.

The gap between code compliance and true watertightness is exactly where installation quality lives. And it is exactly where shortcuts show up after the crew has moved on to the next job.

South Florida Context

Why HVHZ Roofs Face a Higher Leak Risk Than the Rest of the Country

Miami-Dade and Broward operate under the strictest residential building code jurisdiction in the United States — and still see post-inspection leaks every hurricane season.

The High-Velocity Hurricane Zone (HVHZ) provisions in the Florida Building Code were written after Hurricane Andrew revealed how dramatically standard construction codes failed in South Florida conditions. HVHZ requires products to hold NOA or Florida Product Approval with HVHZ scope — additional testing above the baseline FBC requirements applied to the rest of the state.

But product approval tests a product in a lab. It does not test the crew installing it on your roof in August, in intense heat, under schedule pressure. Field installation quality is not something a lab approval document can capture. The HVHZ code is strict on materials; it cannot legislate craftsmanship on every square foot of every deck.

South Florida’s seasonal weather adds a layer that no static pressure test accounts for. A tropical system can push wind-driven rain at extreme angles — sustained for hours, not minutes — and that kind of extended lateral pressure will find every gap a standard inspection missed. That is the real-world test. And it often runs during the first major storm after a new roof is completed.

Where Leaks Actually Come From

The Five Most Common Post-Inspection Failure Points

These are installation gaps that pass visual inspection — and fail under rain.

Parapet wall flashing is the most common culprit we see in Miami-Dade. When a flat-to-sloped transition meets a parapet wall, the counterflashing must be integrated into the wall — not caulked on top of base flashing. In South Florida’s UV environment, caulk can degrade relatively quickly — in our experience, often within a couple of years. The first heavy rain after the caulk cracks is the homeowner’s first leak.

Secondary water barrier (SWB) laps matter because the SWB is your last line of defense if the primary covering is breached by a storm. The Florida Building Code specifies minimum lap requirements, but a crew working fast on a hot deck may lap by less than the required amount — or not bond the lap at all. That passes a visual check. It fails when rain blows sideways under lifted tiles during a tropical storm.

Penetration seals are another common shortcut: a cone boot is seated around a plumbing vent, caulked at the flange, and the inspector sees a sealed penetration. What is not visible is whether the crew also integrated a peel-and-stick membrane collar as required for HVHZ conditions. Caulk alone on a roof penetration in South Florida is a ticking clock.

Understanding what drives roofing costs in South Florida helps homeowners recognize when a bid is too low to include proper flashing and SWB work — a bid that skips these steps often looks competitive right up until the first storm.

Inspection vs. Warranty — Understanding the Difference

What a Passed Inspection Covers vs. What Your Contractor Warranty Covers

Florida Statute 553.84 is generally understood to establish an implied warranty that contractor work complies with the Florida Building Code — consult a Florida construction attorney for how this applies to your specific situation. A passed inspection does not extinguish this implied warranty framework — it simply establishes that the work appeared code-compliant on inspection day. If a subsequent leak is attributable to an installation defect (not storm damage beyond the roof’s design rating), the contractor may still bear responsibility.

Practical steps if you have a post-inspection leak: document everything with dated photographs before any emergency repair. Contact your contractor in writing (email creates a timestamp). If the contractor is unresponsive, consult a public adjuster or a construction attorney who handles Florida roofing warranty disputes. Do not let another contractor patch the leak before the original roofer has had a chance to inspect — that can complicate warranty claims.

Roofing Systems and Leak Resistance

How the Roofing System You Choose Affects Post-Storm Performance

Material choice sets the ceiling on how watertight your roof can be — but installation quality determines whether it reaches that ceiling.

Every roofing system Bigfoot installs is selected for South Florida conditions. For shingle roofs, Bigfoot uses a GAF peel-and-stick full-deck underlayment system that qualifies as a secondary water barrier for insurance purposes — something 30-lb felt cannot do. Under the 2024 Florida Building Code update, direct-to-deck peel-and-stick is permitted statewide, and in HVHZ it is the standard Bigfoot uses on every shingle job. This is the layer that protects your home if a storm lifts shingles — it is also the layer where lap bonding shortcuts most commonly hide.

For metal roofing, Englert panels are roll-formed on-site from 24-gauge C4 steel, running in one continuous piece from ridge to eave — no horizontal seams means fewer potential leak points at horizontal transitions. The clip system uses Englert-stamped clips that allow thermal float, which matters in South Florida’s heat cycles. A roof that cannot float will buckle and create gaps over time.

For tile, Westlake concrete tile installed with poly-set foam adhesive attachment is rated to 180 mph in South Florida conditions (per Bigfoot Windows & Roofing warranty documentation). Foam adhesive also reduces the chance of wind-lifted tiles exposing the underlayment — which is the primary leak mechanism in a tile roof during a hurricane.

Installed cost context as of mid-2026 (per Bigfoot Windows & Roofing pricing data): architectural shingles typically run $750–$850 per square installed; standing-seam metal $1,050–$1,300 per square; concrete or clay tile $1,000–$1,350 per square. These ranges reflect South Florida permit, material, and labor costs and move based on roof complexity, pitch, and access.

If you are comparing roofing system options for your South Florida home, the quality of the underlayment, flashing, and SWB installation matters as much as the surface material you choose.

What to Do If Your New Roof Is Leaking

Step-by-Step: Documenting and Pursuing a Post-Inspection Leak Claim

1. Document before touching anything. Take dated photos and video of every wet area, every stain, and every visible entry point. Note the date of the storm event that triggered the leak.
2. Notify your contractor in writing. Send an email — not just a phone call — describing the leak, the date, and the conditions. Written notice with a timestamp is important if the dispute escalates.
3. Request a written response within a reasonable timeframe. Florida does not specify a mandatory response window for warranty claims, but documented written notice starts the clock on any subsequent legal action.
4. Do not authorize a patch repair by a third party first. If you allow another contractor to patch before your original roofer inspects, the original roofer may argue the source cannot be confirmed. Emergency tarping is acceptable to prevent further damage — document it thoroughly.
5. If the contractor is unresponsive, escalate. Contact the Florida Department of Business and Professional Regulation (DBPR) or consult a construction attorney familiar with Florida roofing warranty obligations under F.S. 553.84.
6. Check your homeowner’s insurance. If the leak resulted from storm damage (as opposed to pure workmanship failure), your HO policy may cover it — though the claim could affect future premiums. A public adjuster can help parse what is storm damage versus installation defect.

Who We’re Not the Right Fit For

• Homeowners seeking the lowest bid on the street. Proper HVHZ flashing, full-deck peel-and-stick SWB, and Englert-stamped clip systems cost more than shortcuts. If price is the only criterion, you will likely find a lower number elsewhere — and you may find out why after the first storm.
• Projects requiring licensed electrical, plumbing, or HVAC scope. Bigfoot holds Certified General Contractor, Certified Residential Contractor, Certified Roofing Contractor, and Certified Specialty Contractor with a Glass & Glazing Specialty licenses. We do not hold electrical, mechanical, or plumbing licenses. Those trades require their own licensed contractors.
• Commercial high-rise roofing projects. Our residential and HVHZ expertise is focused on single-family homes, low-rise residential buildings, and small multi-family properties. Large-scale commercial roofing is outside our current scope.
• Homeowners who want guaranteed insurance savings figures in writing. Wind mitigation improvements can significantly affect insurance premiums — but specific savings numbers depend on your insurer, policy, and wind mitigation inspector’s findings. We will not quote a dollar amount we cannot guarantee.
