Roofing Warranties: Materials & Workmanship | Bigfoot Windows & Roofing
Key Takeaways
- Manufacturer warranties cover material defects; workmanship warranties cover installation errors — they are separate documents with separate claims processes.
- In Florida’s High-Velocity Hurricane Zone (HVHZ), improper installation or unpermitted repairs can void both warranty types simultaneously.
- GAF’s Wind Proven warranty has no maximum mph cap and is not voided by a named storm hitting your county — a meaningful advantage in South Florida.
- Using a Florida-licensed contractor is not optional for warranty enforceability; most manufacturers require it as a condition of coverage.
- Roof warranties can transfer to a new buyer in many cases, but the window to register the transfer is typically 30–60 days after closing.
The Warranty Problem
Most Homeowners Don’t Know What Their Roof Warranty Actually Covers
Until the claim is denied — and then it’s too late.
A new roof is one of the largest investments a South Florida homeowner will make. Yet most people sign the final paperwork without fully understanding what the warranty actually protects — and what it doesn’t. When a roof fails three years after installation, the conversation changes fast. Suddenly, terms like “prorated,” “workmanship exclusion,” and “licensed installer requirement” matter enormously.
There are two distinct warranty types on every roofing project: the manufacturer’s material warranty and the contractor’s workmanship warranty. They cover different failures, are administered by different parties, and can be voided by completely different actions. Understanding both before you sign is how you actually protect your investment.
South Florida Context
Why Roofing Warranties Are More Complex in Miami-Dade and Broward
South Florida sits in the High-Velocity Hurricane Zone (HVHZ) — Miami-Dade and Broward counties operate under the strictest building code in the United States. Every roofing material installed here must carry a Miami-Dade Notice of Acceptance (NOA) or a Florida Product Approval, and every installation must follow the Florida Building Code’s prescriptive fastening schedules, underlayment requirements, and inspection protocols.
This matters for warranties because manufacturers write their warranty terms around code-compliant installation. If your contractor skips a required inspection, uses a non-approved fastener pattern, or performs a repair without a permit, the manufacturer can legitimately deny a future claim — even if the defective material itself has nothing to do with the installation shortcut.
The Florida Building Code also governs the 25% damage rule: if 25% or more of a roof is damaged or replaced, the entire roof must be brought up to current code. That can affect the scope of warranty coverage on an older section of the same roof. An experienced roofing contractor in South Florida should walk you through how this applies to your specific project before work begins.
Understanding the Two Warranties
Material Warranty vs. Workmanship Warranty: What Each Covers
These two documents are issued by different parties and address different failure modes. Here is how they break down:
| Feature | Manufacturer Material Warranty | Contractor Workmanship Warranty |
|---|---|---|
| Who issues it | Shingle, metal, or tile manufacturer | Your roofing contractor |
| What it covers | Defects in the material itself (premature granule loss, cracking, delamination) | Errors in installation (improper flashing, missed fasteners, water intrusion from technique) |
| Typical duration — standard | 20–30 years (prorated after year 10 on many products) | 1–10 years depending on contractor and product tier |
| Typical duration — enhanced | 50-year non-prorated (requires certified installer) | Up to 10 years (Bigfoot: 10-year workmanship warranty) |
| Who you call for a claim | Manufacturer’s warranty claims department | Your contractor directly |
| Key void trigger | Non-licensed installer, unpermitted repair, non-approved materials | Homeowner modifications, acts of God beyond wind design pressure, natural wear |
The key insight: a material failure caused by a workmanship error is often excluded from the manufacturer’s warranty and vice versa. That gap is where most claims fall through. The cleaner solution is to ensure your contractor is both the certified installer for the manufacturer’s enhanced warranty and carries their own workmanship coverage — so accountability doesn’t shift between two parties when something goes wrong.
Warranty Tiers Compared
How Roofing Warranty Tiers Stack Up in South Florida
| Warranty Tier | Coverage Type | Wind Coverage | Named Storm Protection? |
|---|---|---|---|
| Standard manufacturer (shingle) | Material defects only, prorated | Capped at 110–130 mph | Often voided if named storm hits county |
| GAF System Plus (Silver Plus certified installer) | Shingles + labor + tear-off + accessories, 50-yr non-prorated | Wind Proven — no mph cap | NOT voided by named storm in county |
| Metal standing seam (Englert) | 50-year finish + structural warranty | Rated to code; clip system verified | No named storm exclusion on structural warranty |
| Stone-coated steel (Unified Steel) | Lifetime warranty | VSH-rated panels | No named storm, no saltwater, no act-of-God exclusions |
| Contractor workmanship (Bigfoot) | Installation errors, flashing, penetrations | Matches installed system design pressure | 10-year term from installation date |
The GAF Wind Proven warranty deserves special attention for South Florida homeowners. Most competitors cap wind coverage at 130 mph or void coverage entirely if a named storm makes landfall in your county — even if your specific roof performed perfectly. GAF Wind Proven removes the mph cap and the named-storm county trigger. For a home in Miami-Dade or Broward, that distinction is material.
License & Accountability
Why the Contractor’s License Determines Whether Your Warranty Is Valid
A licensed contractor is not a formality — it is a warranty condition.
Nearly every major manufacturer — GAF, Englert, Westlake — requires that the installing contractor hold a valid state roofing license as a condition of the enhanced warranty. If your contractor was unlicensed, their work is also unpermitted by definition under Florida law, which means the installation does not appear in county records. When you file a warranty claim, the manufacturer can verify permit history. An installation that does not appear in the permit record is one the manufacturer did not agree to warranty.
Beyond warranty enforceability, Bigfoot’s Certified General Contractor license (CGC1531370) means structural work — hurricane straps, roof deck repairs, load path corrections — can be handled in-house under the same permit set. Homeowners do not need to bring in a separate structural contractor when the scope touches anything beyond shingles or panels. That single-contractor accountability is a structural advantage, not a marketing claim.
“When a homeowner files a warranty claim three years after install, the first thing the manufacturer checks is the permit record. If there isn’t one, the claim is gone before it starts. That’s the real reason licensing matters.”
Products We Install
Roofing Systems and Their Warranty Profiles
The warranty behind any roof is only as strong as the system it covers. Here is a plain-English summary of what Bigfoot installs and the warranty profile behind each:
- GAF Timberline HDZ shingles (Silver Plus certified): System Plus warranty available — 50-year non-prorated covering shingles, labor, tear-off, and accessories. Wind Proven warranty: no mph cap, 15-year term, not voided by named storm in county. Shingle lifespan in South Florida typically 12–15 years due to UV and heat load, so maintenance and inspection cadence matters more here than in northern climates.
- Englert standing seam metal: Fabricated on-site using 24-gauge C4 steel. Panels run one continuous piece from eave to ridge — no horizontal seams that could fail under hurricane uplift. 50-year structural warranty. Englert-stamped clip system (6-inch clips at ridge and eave, 2-inch clips in field) is the NOA-compliant installation method; knockoff clips can cause a failed inspection and void the warranty entirely.
- Westlake / Unified Steel stone-coated panels: Lifetime warranty with no named storm, no saltwater, and no act-of-God exclusions — the only stone-coated product line we are aware of that removes those carve-outs entirely. VSH-rated for high-velocity zones.
- Westlake concrete tile (Saxony 900, Barcelona): Manufacturer structural warranty on the tile itself. Installation method matters: poly-set foam adhesive is rated to 180 mph versus 160 mph for mechanical fasteners in South Florida conditions.

What Voids Coverage
Common Actions That Can Void Your Roofing Warranty in Florida
Understanding what voids a warranty is just as important as understanding what it covers. The following are documented — not hypothetical — warranty killers in South Florida:
- Unpermitted repairs: Any roofing repair in Miami-Dade or Broward requires a permit. A contractor who patches your roof without pulling one leaves you with a gap in the permit record. Future claims — from either the manufacturer or your own workmanship warranty — can be denied on this basis alone.
- Non-approved materials in a repair: If a repair uses shingles from a different manufacturer or a non-approved underlayment, it can break the system integrity required by the original manufacturer’s warranty. Always verify material compatibility before approving a patch job.
- Structural modifications without permits: Adding a solar array, cutting a new skylight opening, or modifying the roof deck without a permit voids coverage on the affected area. These are structural modifications that require a Certified General Contractor-level permit — not just a roofing permit.
- Skipped maintenance: Most manufacturer warranties include a maintenance clause. Gutters packed with debris, standing water, or ignored minor damage left for years are grounds for partial or full claim denial.
- Using a non-certified installer: GAF System Plus requires a GAF-certified installer. If your contractor was not certified at the time of installation, the enhanced warranty does not attach — you may have a basic prorated coverage only.
If you are uncertain about the status of your existing warranty, the safest first step is to pull your original permit record from the county and compare it against your warranty registration documents. For roofing projects in Miami-Dade County, permit records are searchable through the county’s online building portal.

Who We're Not the Right Fit For
Bigfoot Windows & Roofing is a licensed roofing contractor serving South Florida homeowners — but we are not the right fit for every situation. Here is an honest look at when you should look elsewhere:
- You need the cheapest bid, full stop. If the primary decision driver is the lowest possible number on the page, we are likely not your contractor. Our pricing reflects permitted work, licensed installers, and manufacturer-certified installation — all of which are required to make the warranty you receive enforceable. Contractors who win on price alone are often cutting one of those three corners.
- You want a quick patch without a permit. We do not perform unpermitted roofing work in Miami-Dade or Broward. If you need a rapid cosmetic patch before a home inspection and have no interest in pulling a permit, we will point you toward the proper permit process — but we will not skip it.
- You are outside our service area. We operate in Miami-Dade, Broward, and Palm Beach counties. Projects in Central or North Florida are outside our licensed operating area.
- Your project requires licensed electrical, plumbing, or HVAC trades as the primary scope. Our four licenses cover general contracting, residential, roofing, and glass & glazing. We do not hold electrical, plumbing, mechanical, or HVAC licenses and will refer those primary-scope projects accordingly.
Homeowner Questions
Frequently Asked Questions
What is the difference between a roof material warranty and a labor warranty in Miami?
A material warranty is issued by the manufacturer and covers defects in the product itself — premature cracking, delamination, or granule loss. A labor (workmanship) warranty is issued by your contractor and covers installation errors like improper flashing, missed fasteners, or water intrusion caused by technique. They are separate documents, filed with separate parties, and each has its own exclusions. Both are required to have complete coverage.
Does my roof warranty cover hurricane damage in Florida?
It depends on the specific warranty. Standard manufacturer warranties often cap wind coverage at 110–130 mph and may void coverage if a named storm is declared in your county — even if your roof held. GAF’s Wind Proven warranty removes the mph cap and does not void coverage based on named-storm county declarations, making it a materially stronger option for South Florida homes in Miami-Dade and Broward.
How long do roofing warranties last in South Florida?
Material warranties range from 20–30 years for standard products to 50 years or lifetime for premium systems installed by certified contractors. Workmanship warranties typically run 1–10 years; Bigfoot provides a 10-year workmanship warranty. Note that shingle lifespan in South Florida is typically 12–15 years due to heat and UV load — the warranty term and the practical service life are two different numbers.
What happens to my roof warranty if I sell my house in Miami-Dade?
Many manufacturer warranties are transferable to a new owner, but the transfer usually must be registered within 30–60 days of the property closing. The process and any transfer fees vary by manufacturer. Your contractor should provide you with the original warranty registration documents at project closeout. If you are buying a home, request the warranty registration certificate and verify it with the manufacturer directly before closing.
Is a roof warranty valid if the contractor was not licensed in Florida?
For the enhanced manufacturer warranty — no. GAF, Englert, and Westlake all require a licensed, certified installer as a condition of the enhanced warranty. An unlicensed contractor cannot pull a permit under Florida law, meaning the installation has no permit record. When a claim is filed, the manufacturer checks the permit history. No permit record typically means no enhanced warranty — you may fall back to a basic prorated coverage only, if any.
Can I finance a new roof and still qualify for warranty coverage?
Yes. Financing the project — including PACE financing paid through your property tax bill — does not affect warranty coverage. The warranty attaches to the installation, not to how you paid for it. What matters is that the installation was permitted, performed by a licensed certified contractor, and registered with the manufacturer. If you want to explore financing options, our roofing financing page explains how PACE and the My Safe Florida Home grant can be stacked.
