Some construction failures start in the factory, not on the job site. The shingles were installed exactly as the manufacturer directed and still cracked within a few years. The pipe was fitted correctly and still split inside a wall. The drywall was hung properly and still corroded every copper wire and coil in the house. When the material itself is the problem, the claim runs against the people who made it and sold it (the manufacturer, the distributor, the supplier), not just the contractor who put it in.

Cory Cannon represents Tampa Bay homeowners, condominium associations, and business owners in claims over defective building products. I am a Florida attorney with a family history in construction for generations, and my work reflects that background: I read product data sheets, installation instructions, and warranty fine print the same way I read pleadings: line by line. When a case requires proof of how a product failed, we retain independent licensed engineers and materials laboratories to test it.

This page explains how Florida law treats defective building materials: the line between a bad product and a bad installation, who in the supply chain can be held responsible, the court-made rule that shapes almost every one of these cases, the traps written into product warranties, and the deadlines that can quietly end a claim before it starts.

Key findings

  • Product versus workmanship is the dividing line. A good product installed badly is a workmanship claim against the contractor; a good installation of a bad product is a claim against the manufacturer and its supply chain. The physical evidence tells them apart.
  • The economic loss rule turns on what you bought. Under Casa Clara, a product that damages only itself usually leaves you with warranty remedies, while damage to “other property” can open tort claims.
  • The warranty clock can start at delivery, not discovery. The four-year deadline on goods under Florida’s Uniform Commercial Code may run out before the defect ever shows itself.
  • Preserve the failed material. Discarding it before it is documented can constitute spoliation and weaken or end an otherwise strong claim.
  • The initial consultation is free. Bring your photographs, the warranty, and your purchase records, and I will tell you whether the evidence points to the product, the installation, or both.

Defective product or defective installation? The first question in every case

From the owner’s side, a failed product and failed workmanship look the same. Water on the floor is water on the floor. Legally, they are different cases against different defendants under different rules, and sorting them correctly is the first thing we do.

  • Good product, bad installation. The material was sound; the contractor installed it wrong. Shingles nailed above the nail line, supply lines crimped at the fitting, windows set without pan flashing. That is a workmanship claim against the contractor or subcontractor. It belongs on our roofing defect, plumbing, electrical, and HVAC defect, or window and door defect pages, depending on the trade involved.
  • Bad product, good installation. The contractor followed the manufacturer’s instructions and the material still failed, because it was designed wrong, formulated wrong, or built wrong at the plant. That is a product claim against the manufacturer and its distribution chain. That claim is this page.

Often both are true. A marginal product installed carelessly fails faster than either problem would have caused alone. Florida law allows claims against the installer and the product chain in the same lawsuit, with fault apportioned among them. We do not guess at the split; we establish it. The evidence that sorts product from workmanship is physical (the failure pattern, the installation details, the condition of sister materials on the same building), and it is exactly the kind of evidence that gets destroyed when repairs start before anyone documents the failure.

If you are not sure which category your problem falls into, that is normal. Start at our construction defects overview or call us; the initial consultation is free either way.

Building products with documented failure histories

Certain products have failed in large enough numbers that the patterns are well documented in litigation and building-science literature. History is context, not proof (every claim rises or falls on the evidence from your building), but knowing the patterns tells us where to look first.

  • Imported corrosive drywall. During the building boom and the rebuilding surge that followed the 2004 and 2005 hurricane seasons, imported drywall containing reactive sulfur compounds went into thousands of Florida homes. It off-gassed compounds that blackened and corroded copper wiring, air-conditioner coils, and plumbing components, and produced a persistent sulfur odor.
  • Polybutylene supply pipe. Installed widely from the late 1970s through the mid-1990s, polybutylene degraded from the inside out on contact with chlorinated water, then failed suddenly. It was the subject of some of the largest product settlements in U.S. history.
  • Fire-retardant-treated plywood. Certain roof sheathing treated with fire-retardant chemicals in the 1980s broke down under attic heat, losing strength years after installation.
  • Barrier synthetic stucco (EIFS). Exterior insulation and finish systems that had no drainage path trapped wind-driven rain behind the cladding, rotting sheathing and framing while the wall looked fine from outside.
  • Organic-mat asphalt shingles. Shingles built on organic felt mats proved prone to premature cracking, curling, and blistering; manufacturers largely discontinued them, and several faced class litigation over early failures.
  • Engineered wood siding and trim. Some composite and hardboard products absorbed moisture at cut edges and fastener penetrations, then swelled, softened, and rotted well short of their rated life.
  • Insulated glass and window components. Failed edge seals fog the glass; defective vinyl formulations warp and crack frames; bad glazing compounds let water past the sash.
  • Connectors and fasteners in coastal exposure. Straps, clips, and screws sold for exterior use sometimes corrode far faster than their coatings should allow, a particular problem in Tampa Bay’s salt air.

Florida is a punishing test bench. Ultraviolet exposure, daily heat and humidity cycling, salt-laden air, and wind-driven rain find every weakness in a product’s design. Manufacturers market their products for this climate; when a product cannot survive the conditions it was sold for, that gap between the marketing and the performance is the heart of the claim. Florida also runs a statewide product-approval system for building-envelope components: windows, exterior doors, roofing products, and structural connectors, among others. One of our first checks is whether the product on your building matches its approval documents and the test reports behind them.

Who can be held responsible for a defective building material

Responsibility can attach at several points in the chain of distribution, the path a product travels from the plant to your building:

  • The manufacturer, for defective design (the product was drawn wrong), defective manufacture (a bad batch, plant error, substituted ingredients), or inadequate instructions and warnings.
  • The distributor or local supplier that sold the product, particularly where the sale carries warranties under Florida’s version of the Uniform Commercial Code, the statute governing sales of goods.
  • The contractor, where the real problem is selection or substitution: the builder swapped in a cheaper product, used a material outside its rated application, or ignored the manufacturer’s stated limits.

The legal theories vary with the defendant. Strict liability holds a manufacturer responsible without proof of carelessness when a defective product causes damage. Negligence addresses careless design, testing, or quality control. Breach of express warranty enforces the specific promises printed on the packaging and warranty documents. Implied warranties (unwritten guarantees the law reads into a sale, such as that goods are fit for their ordinary purpose) can support claims too, though Florida generally requires privity, meaning a direct buyer-seller relationship, before an implied-warranty claim will stand. And where a product was marketed with claims the manufacturer could not back up, Florida’s Deceptive and Unfair Trade Practices Act may reach conduct the warranty documents try to wall off.

Which theories fit depends on what failed, who sold it, and what the paperwork says. That is analysis we do at the front of the case, not the end, because the choice of theory drives the deadline. More on that below.

The economic loss rule: the doctrine that shapes these cases

One court-made doctrine controls more defective-materials cases than any statute: the economic loss rule. In plain terms, when a defective product damages only itself, Florida law treats the loss as a broken bargain: your remedy is contract and warranty law, not a tort suit. When the product damages other property or injures a person, tort claims such as negligence and strict liability open up.

Two Florida Supreme Court decisions frame the rule. In Tiara Condominium Association v. Marsh & McLennan Companies, 110 So. 3d 399 (Fla. 2013), the court confined the economic loss rule to products liability cases, which means the rule now lives almost exclusively in cases like these. And in Casa Clara Condominium Association v. Charley Toppino & Sons, 620 So. 2d 1244 (Fla. 1993), the court applied it to a building material directly: a supplier’s concrete contained salt that rusted the reinforcing steel and cracked the buildings. The homeowners’ tort claims failed because, as the court saw it, they had purchased finished homes, not concrete, so the damaged buildings were the product itself, not “other property.”

Casa Clara teaches the question that decides these cases: what, exactly, did you purchase? An owner who bought a completed house from a builder purchased the house; when a component fails and damages the rest of the structure, courts may treat the whole house as the product. But an owner who separately contracted for a re-roof purchased roofing materials; when defective shingles leak and ruin drywall, flooring, and furniture, the interior damage is much more plausibly “other property.” The same failed shingle can support a tort claim in one fact pattern and be limited to warranty remedies in another.

This is not an academic distinction. It determines whether your recovery is capped by the fine print of a manufacturer’s warranty or measured by the actual damage to your building. Framing the product, the purchase, and the damage correctly (and proving the “other property” damage with photographs, moisture mapping, and inspection reports) is where these cases are won or lost. It is also why we treat the economic loss rule as a design constraint from day one rather than a surprise raised in a motion to dismiss.

The warranty fine print, read line by line

Manufacturers know most failing products will be evaluated first under the warranty they wrote. Those documents are drafted to shrink the claim, and the techniques repeat:

  • Registration hurdles. Coverage that quietly lapses or downgrades because no one mailed a card or completed an online registration within 30 or 60 days of installation.
  • Proration. A “30-year” or “lifetime” product whose payout shrinks every year, so a failure in year twelve returns a fraction of replacement cost.
  • Materials-only remedies. The manufacturer offers replacement product but nothing for tear-off, labor, disposal, or the interior damage the failure caused, routinely the largest part of the loss.
  • Transfer restrictions. Coverage that dies, or drops to a short fixed term, when the home is sold.
  • Short claim windows and notice traps. Requirements to report within weeks of discovery, submit samples on the manufacturer’s schedule, or use the manufacturer’s chosen inspector.
  • Disclaimers and remedy limits. Language attempting to strip the implied warranties and cap every remedy at the purchase price, sometimes paired with arbitration and out-of-state venue clauses.

The fine print is not always enforceable as written. Florida’s Uniform Commercial Code requires disclaimers of implied warranties to meet specific formal requirements, including conspicuous placement. A remedy limitation can fail when the promised fix (endless replacement shingles for a roof that needs full replacement) does not actually remedy anything. And warranty language cannot launder deceptive marketing. I read these documents the way I read a carrier’s estimate: line by line, checking every number the manufacturer offers against real bids from licensed local contractors for the repair the building actually needs.

Deadlines: overlapping clocks, and the shortest one may control

Defective-materials claims sit at the intersection of several limitation periods (the statutory deadlines for filing suit), and choosing the wrong one is fatal. The principal clocks in Florida:

Claim Deadline When the clock starts
Breach of warranty on goods (UCC, § 672.725, Fla. Stat.) 4 years Tender of delivery of the goods, generally regardless of when you discovered the defect. A warranty that explicitly promises performance for a stated future period can move the trigger to discovery, but courts read that exception narrowly.
Construction defect claims against contractors, builders, and others involved in the improvement (§ 95.11, Fla. Stat.) 4 years, capped by a 7-year outer bar Latent (hidden) defects run from discovery, but the 2023 statute of repose (an absolute cutoff that runs even before you could have known) bars suit 7 years from the earliest of the temporary certificate of occupancy, the certificate of occupancy, or the certificate of completion (or abandonment of unfinished construction).
Negligence 2 years for causes of action accruing after March 24, 2023 Generally when the damage occurs; older causes of action carry the prior 4-year period.
Products liability (§§ 95.11, 95.031) 4 years, capped by a 12-year repose The 4-year period runs from when the defect and the resulting injury are or should have been discovered. A separate 12-year statute of repose (§ 95.031) bars most products suits 12 years after the product was delivered to its first non-commercial purchaser, subject to a “useful life” provision that can lengthen the window where the manufacturer warranted a longer service life. The products subsection also speaks to personal property “not permanently incorporated in an improvement to real property,” language that fuels categorization fights over building materials.
Breach of written contract (§ 95.11) 5 years Generally from the breach.

Notice the trap in the first row: the warranty clock on goods can start at delivery, not discovery. A pipe that fails in year six of quiet service may already be outside the UCC window even though you learned of the defect yesterday. Notice the second trap: building materials, once incorporated into a structure, sit awkwardly between the products rules and the construction rules, and courts have not drawn the line the same way in every case. Which clock governs depends on the defendant, the theory, and how the product is characterized.

Our practice is to treat the shortest plausible clock as the controlling one and work backward from it. Do the same: these summaries are general information, not advice about your deadline, and the only safe course is to have counsel calculate the dates for your specific facts, early.

Chapter 558: the notice step before most defect suits

Florida’s Chapter 558 requires an owner to serve a written notice of claim before filing most construction defect lawsuits: at least 60 days before suit, or 120 days for associations representing more than 20 parcels. The statute expressly covers suppliers of materials, so a defective-product claim that includes the contractor or the supplying dealer usually passes through this process: notice, an inspection window, and a written response that may offer repairs, money, or a denial. Handled well, the 558 exchange is free discovery: it forces early positions and documents the defect while it is still observable. We explain the full process, for owners and for recipients, in our guide to the Florida 558 notice.

How we build a defective-materials case

First, preserve the evidence. The failed material is the case. Tearing it off and hauling it to a landfill can constitute spoliation (the destruction of evidence) and can damage or end an otherwise strong claim. Before repairs begin: photograph the failure in place, keep generous samples of the failed product (including undamaged sections for comparison), and save packaging, labels, wrappers, and any visible batch or lot numbers. Keep every purchase record, delivery ticket, and contract. If emergency repairs cannot wait, document first and preserve samples anyway. We can work with that.

Second, establish the failure mechanism. We retain independent licensed engineers and materials laboratories to determine how the product failed: formulation analysis, accelerated-aging comparison, fastener and coating testing, whatever the material calls for. We pull the manufacturer’s data sheets, installation instructions, marketing claims, and Florida product-approval file and line them up against the product’s actual performance. Where the product went into a subdivision or condominium community, we look for the same failure on neighboring buildings, because a pattern across many installations by different crews is powerful evidence that the product, not the workmanship, is the cause.

Third, prove the loss. The measure of damage is what it actually costs to remove the failed product, repair what it ruined, and replace it with something that works. I grew up around construction; I know what those numbers look like when they are real, and I check every figure (the manufacturer’s, and anyone else’s) against bids from licensed local contractors.

If your real dispute is with your insurance company

Many owners find a product problem only after filing an insurance claim for the resulting water or storm damage, and sometimes the fight that matters most is with the carrier over coverage, scope, or price rather than with the manufacturer. Those are different claims under different law, and they can proceed alongside a product claim. If your immediate problem is a denied, delayed, or underpaid claim on your own policy, start with our property insurance claims practice.

Fees, and what a consultation looks like

Fee arrangements depend on the matter. Some owner-side defect and product claims may be accepted on contingency or under a hybrid arrangement. Under a contingency agreement, no recovery means no attorney’s fee, case costs, or expenses are owed. Some claims also carry fee-shifting under the governing contract. The written engagement agreement states the terms before work begins.

The initial consultation is free. Bring what you have: photographs, the product warranty, purchase or closing documents, repair estimates, and any correspondence with the manufacturer or contractor. I will tell you plainly whether the evidence points to the product, the installation, or both, and what the deadlines look like from where you stand.

Frequently Asked Questions

How do I know if my problem is a defective product or a bad installation?

The physical evidence decides it. If the material failed the same way in places installed by different crews, or failed even where the manufacturer's instructions were followed exactly, the product is the likely cause; if the failure tracks installation errors like wrong fasteners or missing flashing, it is a workmanship claim against the contractor. Often both contributed, and Florida law allows claims against the installer and the manufacturer in the same lawsuit with fault divided between them. An inspection by an independent licensed engineer, before repairs destroy the evidence, is usually what settles the question.

Can I sue the manufacturer if the defective product only damaged itself?

Usually not in tort, but you may still have warranty and contract claims. Under Florida's economic loss rule, a product that damages only itself is treated as a broken bargain, so the remedy comes from the warranty and the sales contract rather than a negligence or strict liability suit. If the product damaged other property (defective shingles that ruined drywall and flooring, for example), tort claims can open up, though whether damage counts as "other property" depends on what you purchased and from whom. That analysis, framed by the Florida Supreme Court's Casa Clara decision, often decides the whole case.

The manufacturer's warranty only offers replacement materials, not labor. Is that really all I can recover?

Not necessarily. Warranty documents are written to shrink the claim, but their limits are not always enforceable: Florida's Uniform Commercial Code requires disclaimers of implied warranties to meet specific formal requirements, and a remedy limitation can fail when the promised fix, free shingles for a roof that needs a full tear-off, does not actually remedy the loss. Deceptive marketing claims can also reach beyond the warranty's four corners. Have the fine print read line by line before accepting a materials-only offer.

Should I keep the failed materials after repairs?

Yes. The failed material is the core evidence in the case, and discarding it can constitute spoliation, which can weaken or end an otherwise strong claim. Before repairs begin, photograph the failure in place, keep generous samples of the failed product plus undamaged sections for comparison, and save packaging, labels, and any batch or lot numbers along with purchase records and delivery tickets. If emergency repairs cannot wait, document everything first and preserve samples anyway.

How long do I have to sue over defective building materials in Florida?

It depends on the claim, and the shortest plausible clock should be treated as controlling. Warranty claims on goods generally run 4 years from delivery, not discovery, under section 672.725; negligence claims accruing after March 24, 2023 run 2 years; construction defect claims carry a 4-year period with a hard 7-year statute of repose measured from certificates of occupancy or completion; products liability claims run 4 years but are also capped by a 12-year statute of repose that runs from delivery to the first non-commercial purchaser; and written contract claims run 5 years. Because incorporated building materials sit between the products rules and the construction rules, have counsel calculate your specific deadlines early.

Do I have to send a Chapter 558 notice before suing over a defective building product?

Usually, yes. Florida's Chapter 558 requires a written notice of claim before most construction defect lawsuits, and the statute expressly covers suppliers of materials, so a product claim that names the contractor or the supplying dealer generally runs through the 558 process first, at least 60 days before suit or 120 days for associations representing more than 20 parcels. The exchange includes an inspection window and a written response that may offer repairs, money, or a denial. Handled well, it forces early positions and documents the defect while it is still observable rather than simply delaying the case.

Who can be held responsible for a defective building material: the manufacturer or the contractor?

It can be more than one party along the chain of distribution. The manufacturer may be liable for a defective design, a bad batch, or inadequate instructions; a distributor or local supplier may be liable on the warranties that came with the sale; and the contractor may be liable where the real problem was choosing the wrong product, substituting a cheaper one, or using a material outside its rated application. Florida law lets you pursue the installer and the product chain in the same lawsuit, with fault apportioned among them. Which parties belong in the case depends on what failed and what the paperwork shows.

My home is decades old. Could a known-bad product like Chinese drywall or polybutylene pipe still be behind the damage?

It is possible, and the history helps us know where to look. Several building products have failed in documented patterns: imported drywall that off-gassed sulfur compounds and corroded copper wiring and coils; polybutylene supply pipe that degraded from the inside and failed suddenly; and barrier synthetic stucco (EIFS) that trapped water behind the wall. History is context, not proof (every claim rises or falls on the evidence from your own building), and because these products are old, the limitation and repose clocks can be a real obstacle, so the deadlines need to be checked early.

The manufacturer says my warranty lapsed because I never registered the product. Is that the end of it?

Not necessarily. Registration requirements, proration schedules that shrink a "lifetime" payout every year, and transfer restrictions that cut coverage when a home is sold are common warranty techniques, but they are not always enforceable as written. Florida's Uniform Commercial Code sets formal requirements for disclaiming implied warranties, and deceptive marketing can reach past the warranty's fine print. Have the document read line by line before you accept that coverage is gone.

What is Florida's product-approval system, and why does it matter to my claim?

Florida runs a statewide product-approval system for building-envelope components (windows, exterior doors, roofing products, and structural connectors, among others) under which each product is tested and approved for stated conditions. One of our first checks is whether the product actually on your building matches its approval documents and the test reports behind them. A mismatch, or performance that falls short of what the approval promised for this climate, can be strong evidence that the product, not the installation, is the problem.

My insurance company is fighting me over the damage. Is that the same as a defective-product claim?

No. A dispute with your carrier over coverage, scope, or payment is a different claim under different law from a claim against a product manufacturer, though the two can proceed alongside each other. Many owners discover a product problem only after filing an insurance claim for the resulting water or storm damage. If your immediate problem is a denied, delayed, or underpaid claim on your own policy, that belongs with our property insurance claims practice, and we can point you there.
