Replacing your roof is one of the biggest investments you’ll make as a homeowner. While many homeowners spend time comparing roofing materials, colors, and contractors, the warranty is another important part of the project that can affect what happens if a problem develops later.
Misunderstandings often arise when homeowners assume a new roof is protected against every future problem, only to discover that a leak, damaged shingles, or an installation issue falls outside the applicable warranty.
Warranty terms vary depending on the manufacturer, contractor, materials, roofing system, and maintenance history. Coverage, exclusions, transfer provisions, and reporting requirements can also differ between warranty programs.
For Florida homeowners, these differences can be particularly relevant. Intense UV exposure, heavy rainfall, tropical storms, hurricanes, and year-round humidity can affect roofing materials and installation over time.
This guide explains how roofing warranties work, the differences between manufacturer and workmanship coverage, common exclusions, wind-related provisions, warranty claims, and several Florida rules that may affect roofing projects.
Why Roofing Warranties Matter More in Florida
A roofing warranty and homeowners insurance serve different purposes. Insurance generally addresses covered losses caused by events such as hurricanes, hailstorms, falling trees, or fire, subject to the applicable policy. A warranty generally addresses specified defects in materials or problems attributable to installation.
For homeowners in Flagler, Volusia, and St. Johns counties, frequent hurricanes, heavy rainfall, and year-round UV exposure can affect the long-term performance of roofing systems.
According to the Insurance Institute for Business & Home Safety (IBHS), prolonged UV exposure, moisture, elevated roof temperatures, and repeated weather exposure can contribute to the aging and deterioration of roofing materials.
Even high-quality shingles can develop problems if they are installed incorrectly, while a properly installed roof may still develop a manufacturing defect. A material defect and an installation error can produce the same symptom — a leak — but different warranties answer for them. That distinction is the reason both types of coverage matter, and it is worth understanding before a problem appears rather than after.
The Two Types of Roofing Warranties Every Homeowner Should Know
Most roof replacement projects involve two different forms of warranty protection. One generally concerns the roofing products, while the other concerns the installation.
Manufacturer Roofing Warranty
A manufacturer’s warranty applies to the roofing materials themselves. If shingles crack, split, curl, or experience another covered manufacturing defect, the manufacturer may provide a remedy according to the published warranty terms.
Many major manufacturers offer limited lifetime warranties on certain asphalt shingle products. Metal and tile systems may also have long-term or limited lifetime warranties. The word "lifetime" does not necessarily mean unlimited protection for every future owner or every component of the roof. Under many manufacturer programs, lifetime coverage refers to the period during which the original owner owns the property, subject to the applicable terms. Owens Corning publishes its warranty programs and the differences between them, which is a useful reference point when comparing what a contractor is actually offering you.
Transfer provisions can also be limited. A warranty may permit one transfer within a specified period after a property sale, while other programs may impose additional conditions.
Proration is the detail most homeowners miss. Many manufacturer warranties begin with a non-prorated period, during which a covered defect is remedied at full value — in some programs this also includes the labor to replace the defective material. After that period ends, coverage typically continues on a prorated basis: the compensation is reduced according to how many years have passed since installation, and it usually covers materials only, not the cost of the work.
The practical consequence is that the headline number on a warranty describes how long some coverage lasts, not how long full coverage lasts. When comparing warranties, the length of the non-prorated period is usually the more meaningful figure, and it should be stated in the written warranty certificate.
Depending on the product and warranty, covered issues may include:
-
manufacturing defects
-
premature cracking or splitting
-
excessive granule loss
-
certain algae-related discoloration
-
specified wind performance
Common exclusions may include:
-
installation errors
-
storm damage
-
improper ventilation
-
structural movement
-
inadequate maintenance
-
damage caused by third parties
The exact coverage depends on the manufacturer’s written warranty.
Roof Installation Warranty (Workmanship Warranty)
A workmanship warranty is provided by the roofing contractor rather than the manufacturer. It generally addresses problems attributable to the installation. For example, improperly installed flashing, underlayment, or fasteners may create problems even when the roofing materials themselves are not defective.
Workmanship terms vary considerably between contractors — more than most homeowners expect. The National Roofing Contractors Association puts it plainly: many contractors offer one or two years of coverage, and there is no industry standard at all. That makes the workmanship term one of the few genuinely comparable numbers between two quotes, and it is worth asking for in writing rather than in conversation.
The written warranty may specify the coverage period, exclusions, maintenance requirements, transfer provisions, and procedures for reporting a potential problem.
A repair warranty may also have different terms from coverage provided for a complete roof replacement. The scope should therefore be evaluated according to the actual work performed and the written documents.
What Roofing Warranties Usually Cover — and Exclude
A warranty is not a blanket promise to repair every future roofing problem. Coverage depends on the specific agreement, the materials involved, the party providing the warranty, and the cause of the problem.
Manufacturer warranties generally address defects in roofing products. Depending on the product and applicable terms, coverage may include manufacturing defects, premature cracking or splitting, excessive granule loss, certain algae-related discoloration, and specified wind performance.
Workmanship warranties generally address installation-related problems. Depending on the contractor’s written terms, this may include certain issues involving flashing, underlayment, fasteners, or other installation components.
Common exclusions can include:
-
hurricane and other storm damage
-
wind or debris damage outside stated warranty limits
-
fire, lightning, flooding, or falling trees
-
improper maintenance
-
unauthorized modifications
-
structural movement
-
conditions unrelated to the product or installation
-
repairs or alterations that do not comply with warranty requirements
A roofing warranty and homeowners insurance therefore address different types of risk. A warranty generally applies to specified product or installation issues, while insurance coverage depends on the applicable policy and the cause of the loss. Storm damage is the clearest example: it is normally an insurance question rather than a warranty question, and we explain how that side works on our storm damage and insurance page.
The relevant documents determine the actual scope of protection, exclusions, labor provisions, transfer rules, maintenance requirements, and reporting procedures.
Wind-Related Warranty Coverage
Wind-related warranty coverage depends on the specific product and installation requirements. A shingle’s published wind rating does not necessarily mean that an enhanced rating applies automatically to every installation.
Certain higher wind ratings may require specific fastening patterns, installation methods, accessory requirements, or other conditions described in the manufacturer’s warranty. Coverage may also be subject to time limits and additional exclusions. This is one of the places where the installation and the warranty are directly linked: the rating on the wrapper is conditional on the roof being built the way the manufacturer specifies.
A published wind rating and an insurance coverage determination are separate matters. The warranty documents establish the manufacturer’s contractual terms, while insurance coverage depends on the applicable policy and the insurer’s determination.
Roof Repair Warranty vs. Roof Replacement Warranty
A repair warranty and a replacement warranty can apply to different portions of a roofing system and may contain different terms. A repair warranty typically applies to the area where the work was performed. It may not extend to the remainder of an older system, and its coverage period may differ from that of a complete replacement.
A replacement warranty generally applies to a newly installed system, subject to the manufacturer’s and contractor’s respective terms.
For example, if flashing is repaired on one section of an existing roof, the applicable warranty may be limited to that repair. A complete replacement may involve both a manufacturer’s product warranty and a contractor’s workmanship warranty beginning according to their respective documents. That difference is worth raising when you are weighing a roof repair against a full replacement.
The written scope, coverage period, exclusions, and reporting requirements should be reviewed when comparing repair and replacement work.
How Roofing Warranty Claims Are Generally Handled
Warranty claims generally begin by identifying the applicable warranty and documenting the reported condition.
If the issue appears to involve a product defect, the applicable manufacturer warranty establishes where and how the claim is submitted — Owens Corning, for instance, takes warranty claims through its own online form. If the issue appears related to installation, the contractor’s warranty documents establish the applicable inspection and reporting process.
Documentation may include:
-
the roofing contract
-
warranty certificates
-
photographs of the reported issue
-
the original installation date
-
maintenance or inspection records
Warranty review timelines vary by manufacturer, contractor, warranty program, and the nature of the reported problem. The applicable documents may establish notification periods, inspection procedures, and other requirements.
Some manufacturer warranties require evidence that the system has been reasonably maintained. Periodic inspection and maintenance records can provide documentation concerning the condition and history of the roofing system. Specific maintenance requirements should be determined from the applicable warranty documents and manufacturer instructions.
After a claim is submitted, the manufacturer or contractor may inspect the reported condition to determine whether it falls within the applicable terms. The resulting determination may identify what work or costs, if any, are covered.
Warranty documents may also establish specific time periods for reporting a potential problem. Delayed notice may affect a claim when the applicable warranty requires notice within a specified period, so it is worth reporting a suspected issue promptly rather than waiting to see whether it worsens.
What Can Void Your Roofing Warranty?
Warranty conditions vary, but several circumstances may affect whether a particular problem falls within the stated protection.
Improper maintenance can contribute to deterioration outside the applicable terms. Examples may include allowing debris to accumulate, leaving damaged flashing unaddressed, or failing to follow specified maintenance requirements.
Unauthorized modifications may also affect coverage. Satellite dishes, solar panels, skylights, or other rooftop equipment can alter the system and may be subject to manufacturer or contractor requirements. It is worth checking before the work is done, not after.
Ventilation can also be relevant when the applicable warranty contains specific ventilation requirements. Excessive heat and moisture may affect material performance, and failure to meet stated requirements can affect coverage.
Later repairs or modifications can create additional questions about responsibility when they alter the original system. If another contractor works on a roof still under a workmanship warranty, the effect depends on the applicable warranty language and the nature of the subsequent work.
Regular roof inspections, particularly after hurricanes or severe storms, can help document the condition of a roofing system. Records of maintenance and repairs can also provide useful information when reviewing a potential warranty issue.
Florida’s 25 Percent Roof Rule
Florida building-code requirements can affect roofing work independently of warranty coverage. One provision that may be relevant to existing roofing systems is Florida Statutes § 553.844(5).
Under this provision, when an existing roofing system or roof section was built, repaired, or replaced in compliance with the 2007 Florida Building Code or a subsequent edition, and 25 percent or more of that roofing system or roof section is being repaired, replaced, or recovered, only the portion being repaired, replaced, or recovered is required to be constructed in accordance with the Florida Building Code currently in effect, as applicable.
The provision concerns building-code requirements rather than insurance or warranty coverage. Whether it applies to a particular project depends on the applicable code requirements and the history and configuration of the existing roofing system.
The 2007 Florida Building Code became effective on March 1, 2009. The relevant question is therefore not simply the age of a roof, but whether the existing system or section was built, repaired, or replaced in compliance with the 2007 code or a subsequent edition.
Roofing Warranties, Insurance Claims, and Assignment of Benefits
A warranty and a property insurance policy address different types of protection. A warranty generally concerns specified defects in materials or workmanship, while insurance coverage depends on the applicable policy and the cause of the loss.
Florida also restricts assignment of post-loss benefits under residential and commercial property insurance contracts. The Florida Department of Financial Services states that recent legislative changes prohibit a policyholder from assigning post-loss benefits of a residential or commercial property insurance contract issued or renewed on or after January 1, 2023, and that Assignment of Benefits agreements may not be established for claims under contracts subject to that law. The statute itself, § 627.7152, refers to policies issued on or after that date; the Department’s consumer guidance describes it as issued or renewed. Either way, the date your policy was issued or last renewed is what matters.
An AOB therefore should not be treated as a routine part of a modern Florida roofing project. The legal effect of any particular document depends on the applicable policy, contract language, and statutory requirements.
A roofing contractor can document the physical condition of a roof and describe proposed repair work. Questions concerning insurance coverage, policy interpretation, or the legal effect of an insurance-related agreement are separate matters.
Insurance Claim Timing Is Separate From Warranty Deadlines
Roofing warranty deadlines and property insurance claim deadlines are separate requirements.
Under Florida Statutes § 627.70132, a property insurance claim or reopened claim is generally barred unless notice is given to the insurer within 1 year after the date of loss. A supplemental claim is generally barred unless notice is given within 18 months after the date of loss, subject to the statute’s provisions.
For hurricanes and certain other weather-related events, Florida law provides specific rules for determining the date of loss, including the date a hurricane makes landfall or the date a relevant weather event is verified by NOAA, as applicable.
These statutory deadlines concern insurance claims and are separate from deadlines contained in a roofing warranty. A warranty may establish its own notification, inspection, or claim requirements.
Understanding the Roofing Contractor’s Warranty Terms
The practical scope of a workmanship warranty depends on its written terms, including the coverage period, exclusions, claim procedures, and the party responsible for the warranty.
Contractor licensing and the identity of the party responsible for warranty obligations can also be relevant when reviewing a contract. A workmanship warranty is only as durable as the company standing behind it, which is one reason the licence number and the length of time a contractor has operated locally are worth checking.
Florida law also establishes a specific contract notice for residential roof repair and replacement projects. Under § 489.147(7), a contractor executing a contract to repair or replace the roof of a residential property must include in the contract, or attach to it, statutory language in bold type of not less than 14 points on the page reserved for the property owner’s signature. The notice advises that if the proposed work is related to an insurance claim, the owner should contact their insurance company to verify coverage — including claims, deductibles, and policy terms — before signing, and it acknowledges that the owner has been so advised. The requirement applies to the contract; the language addresses insurance-related work.
Manufacturer certification can also affect available warranty programs. Some enhanced manufacturer warranties are available only when installation is performed by contractors who meet specified training or certification requirements.
Warranty documents should be reviewed for:
-
workmanship duration
-
transfer provisions
-
exclusions
-
maintenance requirements
-
documentation provided after installation
-
procedures for reporting a potential problem

Which manufacturer program a particular roof qualifies for depends on the system installed and the components used, and we will tell you which one applies to your build before you decide. Licensed in Florida, CCC1325974.
Protect Your Investment Before Problems Happen
A new roof is designed to protect a home over its service life, while the applicable warranty defines certain protections that may apply to the materials and workmanship.
Understanding the distinction between manufacturer and workmanship protection, reviewing exclusions and maintenance requirements, and knowing how warranty claims are handled can help clarify the protections and limitations that apply over time.
Warranty terms vary by manufacturer, roofing system, contractor, and project. The applicable documents determine the scope of coverage, exclusions, maintenance requirements, transfer provisions, and procedures for reporting a potential issue.
If you would like someone to look at your roof and explain in plain terms what is covered and what is not, book a free inspection or call (386) 263-7906. We serve Flagler, Volusia and St. Johns counties from our shop in Bunnell, and the inspection is free whether or not you hire us.
Florida’s Best Roofing provides roofing inspections, repair estimates, and documentation concerning the physical condition and repair of roofing systems. The company does not interpret insurance policies, determine insurance coverage, advise homeowners regarding policy benefits, negotiate insurance claims on behalf of homeowners, or provide public adjusting services. Questions regarding insurance coverage, policy interpretation, or claim decisions should be addressed to the insurance company or an appropriately licensed insurance professional.
Insurance Claim Notice
Homeowners are responsible for payment of any applicable insurance deductible. It is insurance fraud punishable as a third-degree felony for a contractor to knowingly and willfully, with intent to injure, defraud, or deceive, pay, waive, or rebate all or part of an applicable insurance deductible. It is also insurance fraud punishable as a third-degree felony to intentionally file an insurance claim containing false, incomplete, or misleading information.
FAQ
What is a roofing warranty?
A roofing warranty is a written agreement that covers specified defects in roofing materials, installation workmanship, or both, depending on the applicable warranty.
What does a roof warranty cover?
Manufacturer warranties generally address specified product defects, while workmanship warranties generally address installation-related issues. Storm damage, inadequate maintenance, and other excluded conditions may fall outside the applicable terms.
What does "prorated" mean on a roofing warranty?
Most manufacturer warranties start with a non-prorated period during which a covered defect is remedied at full value. After that period, coverage usually continues on a prorated basis — compensation is reduced according to the years elapsed since installation, and typically covers materials only. When comparing warranties, the length of the non-prorated period is often more meaningful than the headline number.
Do roofing warranties work differently in Flagler, Volusia, or St. Johns County?
Warranty terms generally come from the manufacturer and contractor and may apply throughout Florida. Local weather conditions and building-code requirements can nevertheless affect the circumstances surrounding a particular project.
Is a roof repair warranty the same as a roof replacement warranty?
No. A repair warranty may apply only to the area where work was performed, while replacement coverage may apply to a newly installed system. The applicable written documents determine the actual scope.
Can I transfer my roofing warranty if I sell my home?
Some manufacturer warranties allow transfer, but the conditions and deadlines vary. The applicable warranty documents determine whether a transfer is permitted and what requirements apply.
What can affect my roofing warranty?
Potential issues include improper maintenance, unauthorized modifications, unapproved repairs, inadequate ventilation where specific requirements apply, and failure to follow stated installation or maintenance conditions. The actual effect depends on the applicable warranty.
How are roofing warranty claims generally handled?
The process generally begins with identifying the applicable warranty and documenting the reported problem. The manufacturer or contractor documents usually specify who handles the claim, what information is required, and how notice should be provided.
What is Florida’s 25 percent roof rule?
Florida Statutes § 553.844(5) provides that when an existing roofing system or roof section was built, repaired, or replaced in compliance with the 2007 Florida Building Code or a subsequent edition, and 25 percent or more of that system or section is being repaired, replaced, or recovered, only the affected portion is required to be constructed in accordance with the current Florida Building Code, as applicable. The provision concerns building-code requirements and does not by itself determine insurance or warranty coverage.
What is an Assignment of Benefits (AOB) in Florida?
An Assignment of Benefits is an agreement that can transfer certain post-loss insurance benefits or related rights to another party. Florida restricts assignment of post-loss benefits for property insurance contracts issued on or after January 1, 2023; the Florida Department of Financial Services describes the restriction as applying to contracts issued or renewed on or after that date, and states that AOB agreements may not be established for claims under contracts subject to the law.
Are insurance claim deadlines different from warranty deadlines?
Yes. Florida law generally provides a 1-year deadline for notice of a property insurance claim or reopened claim and an 18-month deadline for notice of a supplemental claim, measured from the date of loss and subject to the statute’s provisions. These deadlines are separate from notification or claim deadlines contained in a roofing warranty.
Does Florida law provide a cancellation period for some roof contracts after a state of emergency?
Yes. Under § 489.147(6), a residential property owner may cancel a roof repair or replacement contract without penalty within 10 days after execution or by the official start date, whichever comes first, if the contract was entered into within 180 days of the events that are the subject of a Governor’s declaration of a state of emergency and the property is within the geographic area the declaration covers. Cancellation must be sent in writing by certified mail or another method providing proof of delivery.
