Repair or Replace? A Florida Homeowner’s Guide to Making the Right Roof Decision

Estimated reading time: ~10 minutes • Last updated: August 31st, 2025

Key Takeaways

The core rule: Isolated damage on a roof under ~15 years old often merits a professional repair; widespread issues or roofs nearing end-of-life usually require full replacement.
Age matters: Florida asphalt shingle roofs typically last 15–25 years; if you’re near this range, replacement is often the better investment.
Florida’s 25% Rule: If more than 25% of a roof area is repaired/altered within 12 months, the entire section must be brought to current code—often making a full replacement the practical path.
Don’t wait: Delays can cause rot, structural damage, and mold, and may jeopardize warranties and insurance coverage.
Insurance implications: Insurers in Florida increasingly non-renew policies for roofs over ~15 years; replacement may be necessary for insurability.

What You Need to Know

Deciding between a roof repair and a full replacement depends on the extent of the damage, the age of your roof, and your long-term goals. A repair addresses specific, localized issues, while a replacement provides a completely new, integrated system built to modern codes, offering maximum protection and peace of mind. Both options require careful consideration of cost, warranty implications, and insurance requirements.

To start, use this checklist to assess your situation:

Check the Age: Do you know how old your roof is? If it’s over 15 years, replacement is a strong possibility.
Review Your Records: Find any paperwork from your last roof installation, including the contractor and materials used.
Inspect from the Ground: Use binoculars to look for missing shingles, cracked areas, or dark streaks (a sign of algae).
Check the Attic: On a sunny day, look for any beams of light coming through the roof. Check for damp insulation or water stains on the underside of the decking.
Look at Ceilings: Note any new or growing water stains on your ceilings or walls.
Assess Granule Loss: Check your gutters and downspouts for an excessive amount of asphalt granules, which look like coarse black sand.
Document Everything: Take clear photos of any damage you can see safely. This will be helpful when talking to a contractor and your insurance company.

How a Roof Is Evaluated: A Step-by-Step Guide

Professional Inspection: A qualified roofing contractor will perform a thorough, multi-point inspection. They will get on the roof to check for damage that is invisible from the ground, such as lifted flashing, cracked sealant, and soft spots in the decking. They will also typically inspect your attic for signs of leaks and poor ventilation.
Damage Assessment & Estimate: The inspector will document their findings with photos and detailed notes. They will then prepare a written estimate that outlines the scope of work, whether it’s a specific repair or a full replacement. The estimate should detail the materials to be used, labor costs, and permit fees.
Material Selection: If a replacement is needed, you will choose your new roofing materials. The contractor should explain the benefits of different options, such as architectural shingles with high wind ratings or impact-resistant products that may qualify for insurance discounts.
Installation: For a replacement, the old roofing material is torn off down to the wood decking. The decking is inspected and repaired if needed, then a new system is installed, including underlayment, flashing, shingles, and ventilation. A repair involves replacing only the damaged components in a specific area.
Cleanup & Final Walkthrough: A professional crew will clean the site thoroughly, often using magnetic rollers to pick up stray nails. You will then do a final walkthrough with the project manager to confirm the work meets your expectations.
Warranty & Registration: The contractor will provide you with a workmanship warranty, and you will receive documentation for the manufacturer’s material warranty. Ensure your new roof is properly registered with the manufacturer to activate the full warranty coverage.

Decoding Roof Damage: A Symptom-to-Cause Guide

Understanding what you see can help you have a more informed conversation with your roofing contractor. Here are common symptoms Florida homeowners encounter and their likely causes.

Symptom: Missing or Torn Shingles
Common Causes: High winds from hurricanes or severe thunderstorms are the primary culprit. Improper fastening during installation or brittle, aging shingles can also lead to blow-offs. This is a critical issue that requires immediate attention to prevent water intrusion.
Symptom: Lifted or Damaged Flashing
Common Causes: Flashing—the metal strips around chimneys, vents, and skylights—can be lifted by wind or damaged by debris. The sealant around it can also degrade over time due to UV exposure, breaking the waterproof seal.
Symptom: Excessive Granule Loss
Common Causes: A small amount of granule loss is normal as a roof ages. However, large amounts of these sand-like particles in your gutters can signal that the shingles are nearing the end of their life, or have been damaged by hail or foot traffic.
Symptom: Soft or Spongy Decking
Common Causes: This is a serious red flag that indicates the underlying wood decking is wet and likely rotting. It is almost always caused by a long-term, slow leak that has saturated the structure. Poor attic ventilation can also trap moisture and contribute to decking failure.
Symptom: Stains on Interior Ceilings or Walls
Common Causes: This is the most obvious sign of a water leak. The cause can be anything from a single missing shingle to failed flashing. Remember that water can travel, so the leak in the roof may be far from where the stain appears.
Symptom: A Roof Exceeding 20 Years of Age
Common Causes: Age itself is a cause for concern. Decades of Florida sun, heat, and storms break down roofing materials. The sealants become brittle, the shingles lose their flexibility, and the roof’s overall ability to shed water is compromised, even if there are no obvious leaks yet.

Key Factors That Influence Your Decision

Roof Age

The age of your roof is one of the most important factors. An asphalt shingle roof in Florida typically lasts between 15 and 25 years. If your roof is only 5–10 years old and has a small, isolated leak, a repair makes sense. If the roof is over 20 years old, a replacement is often the smarter long-term investment, as chasing leaks on an aging system can become a costly, endless cycle.

Storm History

Florida’s weather takes a cumulative toll. A roof that has weathered multiple tropical storms or a major hurricane has been stressed repeatedly. Even if it looks fine from the ground, high winds can weaken the seals on every shingle, making the entire roof system more vulnerable to the next storm.

Attic Ventilation

Proper ventilation is critical to a roof’s longevity in a hot, humid climate like Florida’s. An attic that is too hot “bakes” the shingles from the underside, accelerating their aging process. Poor ventilation also allows moisture to build up, which can lead to mold and rot in the roof deck. Your roofing contractor should always assess your intake and exhaust ventilation as part of an inspection.

Prior Workmanship

Unfortunately, many roof problems stem from poor installation. Improperly nailed shingles, incorrectly installed flashing, and mismatched materials can lead to premature failure. If a professional inspection reveals widespread installation errors, a full replacement is often necessary to correct the underlying issues.

The Real Cost of Postponing Roof Work

Delaying a necessary roof repair or replacement is rarely a good financial strategy. A small problem left unaddressed can quickly escalate, leading to significantly higher costs and more extensive damage to your home.

The most immediate danger is water intrusion. A slow leak can saturate attic insulation, ruin drywall, and promote the growth of hazardous mold. If the leak reaches the roof’s structural decking, it can cause the wood to rot and delaminate, turning a simple shingle repair into a major structural project.

Furthermore, neglecting your roof can have serious consequences for your warranties and insurance. Most manufacturer warranties require homeowners to perform routine maintenance and address damage promptly. Failure to do so can void your coverage. Similarly, homeowner’s insurance policies require you to mitigate damages. If you fail to fix a known leak, your carrier may deny a subsequent claim for the escalating interior damage it causes.

Pro tip: Fix small issues fast—preventing rot and mold is far cheaper than replacing structural decking later.

Cost, Timelines & Warranties

Understanding the expected costs, project duration, and warranty coverage is essential for planning a major home project like a roof replacement.

A professional roof repair can range from $300 to $1,500 for common issues like replacing a few shingles or sealing flashing. A full roof replacement in Florida typically costs between $10,000 and $30,000+, depending on the home’s size, the roof’s complexity, and the materials chosen.

A repair usually takes a few hours to a full day. A standard replacement on an average-sized home takes 3 to 5 days, including the tear-off, installation, and cleanup.

It’s crucial to distinguish between two types of warranties:

Material Warranty: Provided by the manufacturer and covers defects in the roofing products. “Lifetime” warranties typically cover the product for as long as you own your home but may be prorated after an initial period.
Workmanship Warranty: Provided by your contractor and covers errors in the installation—often the more important warranty, since most failures are due to installation errors.

Common Roofing Material Comparison

Material	Wind Rating (ASTM D7158)	Impact Class (UL 2218)	Typical Warranty	Typical Cost Range (per sq. ft. installed)
Architectural Asphalt Shingles	Class H (up to 150 mph)	Class 1–4	Limited Lifetime	$5 – $9
Standing Seam Metal	Varies (often 140+ mph)	Class 4	30–50 years	$12 – $20
Concrete/Clay Tile	Varies by profile/fastening	Class 3–4	50 years to Lifetime	$15 – $25+

Note: Costs are estimates for planning purposes only. Wind ratings and warranties vary by manufacturer and specific product line. Always verify with your contractor and the manufacturer’s official documentation.

Florida-Specific Roofing Considerations

Roofing in Florida isn’t like roofing anywhere else. Our building codes are among the strictest in the nation, designed to protect homes from hurricane-force winds.

The Florida Building Code (FBC) dictates nearly every aspect of a roof replacement. For example, it requires specific nailing patterns, mandates the use of self-adhered underlayment over the entire roof deck in many cases, and has stringent requirements for how the roof deck is attached to the trusses.

One of the most significant regulations is the “25% Rule” (FBC, Existing Building, 706.1.1). This rule states that if you alter or repair more than 25% of a total roof area, the entire roof must be brought up to the current building code. Because of the extensive changes to the code over the years, this often makes a full replacement the only viable option for a roof with significant damage.

Homes in High-Velocity Hurricane Zones (HVHZ), such as Miami-Dade and Broward counties, must meet even more rigorous standards for materials and installation techniques. Always work with a licensed Florida contractor who understands these complex local requirements and can ensure your roof is fully compliant.

Common Mistakes and Red Flags

Do not ignore a small leak. It will only get worse and more expensive to fix.
Do not hire an unlicensed or uninsured contractor. Verify their license with the Florida Department of Business and Professional Regulation (DBPR).
Do not pay for the entire job upfront. A reputable contractor will ask for a reasonable deposit (typically 10–30%) with the balance due upon satisfactory completion.
Do not sign a contract that has blanks or that you don’t fully understand.
Do not install new shingles over an old layer. This practice is often prohibited by the Florida Building Code, adds excessive weight, and can mask underlying deck problems.

Navigating Insurance & Storm Damage Claims

Document the Damage: Before you do anything else, take photos and videos of the damage to your roof and any resulting interior damage.
Verify Your Coverage: Review your insurance policy to understand your coverage, deductible, and any specific limitations related to roofs.
File a Claim: Contact your insurance company to open a claim. They will assign you a claim number and an adjuster.
Schedule the Adjuster Visit: The insurance adjuster will schedule a time to inspect the damage. It is highly recommended to have your roofing contractor present for this inspection to ensure all damage is properly identified.
Review the Scope of Work: The adjuster will provide a report, called a “scope of work,” that details what they believe is damaged and the amount they will pay for the repairs, minus your deductible.
Handle Supplements: If your contractor finds additional damage that the adjuster missed, they will file a “supplement” with the insurance company to request additional funds.
Complete Repairs: Once the scope and price are agreed upon, your contractor can begin the work.
Depreciation Release: Most policies are Replacement Cost Value (RCV), meaning the insurance company initially pays the Actual Cash Value (ACV) of your old roof. Once you prove the work is complete, they release the remaining funds (the depreciation).

Insurance Verification Checklist

What is my policy type: Replacement Cost Value (RCV) or Actual Cash Value (ACV)?
What is my hurricane or wind/hail deductible?
Does my policy have any age limitations for roof coverage?
Do I have code upgrade coverage (also called Ordinance or Law)?
Is there a “matching” endorsement that requires the insurer to replace undamaged sections to ensure a uniform appearance?
What are the specific requirements for filing a claim and my timeframe for doing so?

Frequently Asked Questions

Can I just repair my roof instead of replacing it?

For minor, isolated issues on a relatively new roof (under 15 years old), a professional repair is often sufficient. However, if the damage is widespread, if you have multiple leaks, or if the roof is nearing the end of its lifespan, a replacement is typically the more durable and cost-effective long-term solution.

How long does a roof replacement take?

An average-sized residential roof replacement in Florida typically takes between 3 to 5 days from start to finish. This includes tearing off the old roof, making any necessary decking repairs, installing the new roofing system, and completing a thorough cleanup. The timeline can be affected by weather and the complexity of the roof.

What is the Florida “25% Rule” for roofs?

The Florida Building Code’s 25% rule states that if more than a quarter of your roof needs repair or alteration within a 12-month period, the entire roof must be brought into compliance with the current building code. This often means a full replacement is required to meet modern standards for underlayment and attachment.

What is a Class 4 impact rating, and is it worth it in Florida?

A Class 4 impact rating (UL 2218) is the highest rating for roofing materials, indicating they can withstand impacts from a 2-inch steel ball dropped from 20 feet without cracking. While Florida’s primary threat is wind, many areas also experience severe hail. A Class 4 shingle can provide superior protection and may qualify you for a discount on your homeowner’s insurance premium.

Can I put new shingles on top of my old ones?

No, this practice, known as a “roof-over” or “layover,” is generally not permitted under the Florida Building Code for shingle roofs. A complete tear-off is required to properly inspect the underlying roof deck for damage and to ensure the new roof is securely fastened to meet wind uplift requirements.

How do I know if my roof has wind damage?

Signs of wind damage include missing, creased, or lifted shingles. After a major storm, look for shingles that are no longer lying flat, as the sealant strip underneath may have been broken by the wind. A professional inspector can identify subtle signs of wind damage that are not visible from the ground.
