REPAIR vs REPLACE Your Roof
A plain-English framework for deciding when a repair makes sense and when it is wasted money.
The short version.
Repair your roof if it is under 12 years old, the damage covers less than 25 percent of the roof (Florida's 25% rule), the underlayment is dry, and there are no recurring leaks. Replace it if it is past two-thirds of its expected lifespan, has multiple leaks, or has been hit by a major storm. In Florida, the 25% rule may force a replacement even if you only wanted a repair.
Five factors. One honest answer.
Run your roof through every row. If the majority of your conditions land in the "Replace" column, repair is rented time.
| Factor | Repair | Replace |
|---|---|---|
| Roof age | Under 12 years (shingle) or under 30 years (tile) | Over 12 years (shingle) or over 30 years (tile) |
| Damage scope | Localized, single section | Widespread, multiple sections |
| Underlayment | Dry, intact | Wet, deteriorated, or showing through |
| Leak history | First leak | Recurring leaks |
| Florida 25% rule | Less than 25% of roof damaged | 25% or more damaged (replacement may be required) |
Florida's 25% rule, explained plainly.
What it is. Florida Building Code provides that when 25% or more of a roof is repaired, recovered, or replaced within any 12-month window, the entire roof system has to be brought up to current code. In practice, that means a sectional repair that crosses the threshold can legally trigger a full replacement at the permit stage.
When it triggers. The clock is the surface area, not the dollar value. A single hailstorm that damaged a 30% wedge of the roof field puts you over. So does a slow-burn pattern of three repairs in 11 months that, added together, exceed a quarter of the roof.
Who enforces it. The Broward County, Palm Beach County, and Miami-Dade County building departments. Permits are pulled at the city or county level and inspected at the city or county level. If the inspector measures a repair area over 25%, the permit gets rewritten as a full replacement and the job halts until the new scope is approved.
Why it matters to you. A roofer who quotes a 30% sectional repair without mentioning the 25% rule is either uninformed or hoping the inspector misses it. Neither one is acceptable. We hold CGC 1507284 and CCC 1328855, both Florida state licenses, and we tell you up front when the rule applies.
The repair scenarios that actually pay off.
Scenario 1
A single storm-cracked tile or two
Tile roofs are zone-replaceable. If a falling branch broke three tiles over the kitchen and the underlayment underneath is dry, that is a one-day repair. Replacing a 30-year tile roof for three broken tiles is a $30,000 mistake.
Scenario 2
Flashing failure on a young roof
Most leaks under 10 years old are flashing leaks, not roof failures. Chimney flashing, skylight flashing, and pipe boots all wear out before the roof field does. Re-flash, re-seal, done.
Scenario 3
A few wind-lifted shingles
A 5-year-old shingle roof that lost 8 shingles in a wind event is a repair, not a replacement. As long as the manufacturer color and line are still made, a competent roofer blends it cleanly.
Scenario 4
Isolated nail pops or exposed fasteners
Sun and thermal cycling back fasteners out over time. Pulling, re-driving, and sealing exposed nails on a sound roof buys you years. This is maintenance, not failure.
The repair scenarios that are usually wasted money.
Honest contractor talk. If your situation looks like one of these, do not let anyone sell you a patch. You will pay twice.
Wasted #1
Patching a 22-year-old shingle roof
If your shingle roof is past 18 years in this climate, every dollar spent on repair is rented time. The deck below is dry-rotting, the underlayment is brittle, and the next storm will find the next weak spot. Replace it.
Wasted #2
Recurring leaks in the same location
If you have repaired the same valley or chimney three times and it is leaking again, the problem is not the patch. It is the system. Stop paying for the same fix and replace the roof section or the whole roof.
Wasted #3
Repair after a wet underlayment finding
Once underlayment is wet, the deck under it is compromised. Slapping new shingles over wet underlayment traps the moisture and accelerates rot. If the inspection finds wet underlayment, repair is not honest. Replacement is.
Wasted #4
Fighting the 25% rule with a sectional patch
If 25% or more of your roof is damaged, Florida code may legally require full replacement. Trying to patch your way around the threshold gets jobs red-tagged at inspection and forces a re-tear-off at your expense.
Insurance and storm damage: when to file, when not to.
File a claim when: a named storm, hail, or hurricane hit your area in the last 12 months and you have visible damage (lifted shingles, broken tiles, exposed underlayment, interior water staining). Have a licensed contractor inspect and document first. The contractor's report is what gets the carrier to scope correctly.
Do not file a claim when: the damage is wear-and-tear, the roof is past its lifespan with no specific storm event, or the deductible exceeds the likely scope. A claim that gets denied still goes on your loss-run history and raises future premiums.
The honest play: get a no-cost inspection first. If we find storm damage that triggers the 25% rule, we tell you and document it before the adjuster shows up. If we find normal aging, we tell you that too, and you skip the claim entirely.
How DR Construction inspects to recommend repair vs replace.
01
Roof field walk
We walk the entire roof, not just the leak area. We document granule loss, tile cracking, fastener exposure, and prior repair scars. Photos go into your file.
02
Flashing and penetrations
Every chimney, skylight, vent pipe, and valley gets inspected. 70% of leaks under 10 years old start at flashings, not the roof field.
03
Underlayment access check
We pull a tile or lift a shingle in suspect areas to assess underlayment moisture. Wet underlayment changes the answer from repair to replace, full stop.
04
Written repair-or-replace recommendation
You get a written report with the call, the reasoning, the 25% rule status, and a price for both options when both are honest. No pressure, no upsell.
