Repair your roof when it’s still in the first half of its life, the damage is limited to one area and the wood underneath is solid. Replace it when it’s near the end of its life, the leaks or damage are spread across the roof, the deck is soft or rotting, or your insurance company won’t renew without a new roof.
In Florida, two rules can also make the decision for you: the 25% rule in the building code and the roof age rules insurers follow. Money matters too, and the cheapest option today isn’t always the cheapest over the next ten years. The guide below walks through each of these in order, so you can make the right call for your roof.
Start With Your Roof’s Age
Age is the first thing to check, because it tells you how much life a repair can actually buy. South Florida’s sun, heat and storms wear roofs faster than in milder climates.
| Roof type | Typical life in South Florida | What usually fails first |
|---|---|---|
| Asphalt shingle | 15 to 20 years | Shingles lose granules, curl and stop sealing |
| Concrete or clay tile | Tiles 40+ years, underlayment about 20 to 25 years | The underlayment under the tiles |
| Standing seam metal | 40+ years | Sealants and fasteners at seams and edges |
| Flat (modified bitumen) | 15 to 20 years | Seams, blisters and drains |
A simple rule of thumb: in the first half of a roof’s life, repairs almost always make sense. In the last quarter, a repair often buys only a few years, and money spent on patches is money not spent on the new roof you’ll need soon anyway.
If you don’t know the age, look up the roof permit on your city or county building department’s website, or check the inspection report from when you bought the house. The permit date is also what your insurer and your wind mitigation inspector will go by.
Tile needs extra care. Your tiles may look fine from the street while the underlayment beneath them (the waterproof layer that actually keeps water out) is cracked and brittle. On a tile roof that’s 20 years or older, leaks often mean the underlayment is failing, and fixing it means lifting the tiles.
Check How Much of the Roof Is Damaged
The next question is how far the problem has spread.
A repair usually does the job when:
- The leak or damage is in one spot, like a pipe boot, a flashing seam or a few missing shingles or tiles
- The roof is dry and solid everywhere else
- The wood deck under the damaged area is firm
- It’s the first real problem the roof has had
A replacement is usually the smarter move when:
- Leaks show up in several rooms or keep coming back after repairs
- The deck feels soft or spongy, or the attic shows dark, water-stained wood in more than one area
- Shingles are losing granules across the whole roof, or tiles are slipping in several places
- Storm damage covers large parts of more than one roof section
After a hurricane, the same test applies, but check what you can’t see. Wind can loosen shingles and tiles across a whole slope without tearing any off, so one missing piece may not be the full story. Our guide to what to do with a storm damaged roof covers the first steps, including documenting everything before any repair.
Florida Rules That Can Make the Decision for You
Even when a repair looks possible, Florida rules can push you toward a replacement.
The 25% rule. Under Section 553.844 of Florida law, if 25 percent or more of a roof section is repaired or replaced within 12 months, that whole section has to be brought up to the current building code. You may have heard that damaging a quarter of your roof means replacing all of it. That’s no longer true for newer roofs. Since 2022, roofs built or replaced under the 2007 Florida Building Code or later (generally permitted after March 1, 2009) only need the repaired part brought up to code. On older roofs, the rule still applies, and a large repair can turn into a section or full replacement.
Roof age and your insurance. Under Section 627.7011, an insurer can’t refuse to write or renew your policy just because your roof is under 15 years old. Once it’s 15 or older, the insurer can ask for an inspection, but it still can’t refuse you on age alone if an authorized inspector finds at least 5 years of useful life left. If you get a roof letter from your insurer, get that inspection before you decide. A roof with life left may only need repairs and a good report.
Matching in Broward. Broward sits in the High Velocity Hurricane Zone, so repair materials need a Miami-Dade approval. Older tile styles and shingle colors are often discontinued. If new pieces can’t be matched, a patch can look obvious, and sometimes the only clean fix is to redo the whole slope.
Repair vs Replacement Cost Over Time
Published 2026 price guides from South Florida roofers put most repairs in these ranges:
| Repair | Typical cost |
|---|---|
| Small leak, pipe boot or flashing fix | $300 to $1,500 |
| A few shingles or tiles replaced | $300 to $2,500 |
| Valley, larger tile area or limited underlayment repair | $1,500 to $5,000 |
| Major repairs across several areas | $5,000 to $15,000 |
A full replacement on a typical 2,500 to 3,000 square foot South Florida roof starts at these ranges:
| Roof type | Installed price per sq ft | Typical roof of 2,500 to 3,000 sq ft |
|---|---|---|
| Asphalt shingle | $6 to $7 | About $15,000 to $21,000 |
| Concrete or clay tile | $10 to $11 | About $25,000 to $33,000 |
| Standing seam metal | $11 to $12 | About $27,500 to $36,000 |
| Flat (modified bitumen) | $6.50 to $7.50 | Depends on the size of the flat area |
These are starting ranges, and every roof needs an on-site estimate. Broward homes usually land toward the top of each range because of the stricter hurricane zone rules. At APEX Roofing of Delray Beach, every compromised sheet of decking under a shingle, tile or metal roof is included in the price, so the number you sign is the number you pay for the wood.
The fairest way to compare the two options is cost per year of roof life. Say your shingle roof is 17 years old and needs a $4,000 repair that will likely buy two more years. That’s $2,000 a year. A new $18,000 shingle roof that lasts 18 years costs about $1,000 a year, comes with a fresh warranty and can lower your insurance premium. Now flip it: on a 6-year-old roof, an $800 repair protects a roof with more than 10 years left, and repairing is the obvious choice.
Repair or Replace: A Quick Decision Guide
Use this flowchart to see where your roof stands, then confirm it with an inspection.
Before you call a roofer, have these ready: the year the roof was installed (your permit record shows it), your insurer’s latest letters about the roof, photos of any leaks or damage, and any past repair invoices.
Important: get a written inspection report before you decide. Ask for dated photos of the roof and attic, and for the roofer to say plainly which problems are repairable and why. If one roofer says “replace” and can’t explain it in specific terms, get a second opinion.
If replacement is where you’re headed, see what a roof replacement costs in Florida for a full breakdown of what drives the price, and the roof replacement process in Florida for what happens step by step.
Frequently Asked Questions
Can I replace just part of my roof?
Yes, sometimes. A single slope or section can be replaced if the rest of the roof is in good shape, as long as the 25% rule doesn’t require more and the new materials can be matched. On a roof near the end of its life, it usually makes more sense to replace the whole thing.
Will my insurance pay to replace my roof or only repair it?
Insurance pays to repair covered damage from a sudden event like a hurricane, not wear and age. If the damaged pieces can’t be matched, Florida law (Section 626.9744) requires the insurer to make reasonable repairs to adjoining areas so the result looks uniform, which can mean a larger repair or a replacement.
Can a new roof go over my old one in Florida?
Rarely. The Florida Building Code doesn’t allow a roof-over when the existing roof is tile, is water-soaked, or already has two layers, and most South Florida re-roofs are full tear-offs. A tear-off also lets the roofer inspect and fix the deck.
Will a new roof lower my insurance premium?
It often does. A new roof can raise your wind mitigation score and helps with renewals. Our guide to the wind mitigation inspection in Florida explains how to get credit for it.
