Repair or Replace?

The Roofing Series, Lesson 5 · Taught by Professor Elias Walls · Researched and reviewed by Grant Doutt, Certified Master Inspector®

🎓 The Professor's Quick Answer

The honest answer comes down to three questions, in this order:

1. What actually failed? A component, like a pipe boot, a flashing, or a few cracked tiles, is a repair. The covering itself wearing out is a replacement.

2. How much life is left? Spending $800 on a roof with two years left is throwing money away. The same $800 on a roof with eight years left is good business.

3. What does your insurance say? In Florida this often decides it. A roof your insurer won't write, or will only cover at a depreciated value, is a replacement whether or not it's leaking today.

And one Florida deadline that catches people: if storm damage is involved, you have one year from the date of loss to notify your insurer of a new or reopened claim, and 18 months for a supplemental claim.

🏫 Welcome Back to the Knowledge Center

We've covered the roof clock, how each material ages, what holds the roof on in a storm, and where roofs really leak. Today we put it together and answer the question that costs the most money: fix it or replace it?

🔍 Start With What Failed

Every roof decision starts here, and a good inspection report should tell you plainly.

A component failed. A cracked pipe boot. A piece of flashing at a wall. A few shingles blown off in a storm. Slipped or broken tiles. A skylight seal. These are repairs, and on a roof with life left, a repair is the right answer. Replacing the whole roof over one failed boot is like replacing the engine over a bad hose.

The covering is wearing out. Widespread granule loss, curling and cracking across the slopes, brittle shingles that snap when touched, tile underlayment failing in several places at once. This isn't one problem; it's the material reaching the end of its service life. Repairs here just move the leak.

The deck is damaged. Soft, delaminated, or rotted sheathing means the water has been getting in for a while. That's structural work, and it usually means opening up the roof regardless.

The test: is this an event, or is this a condition? One storm, one bad flashing, one failed part is an event. Age and wear across the whole roof is a condition.

🔭 Where a Roof Shows Its Age First

A roof doesn't age evenly, and knowing where to look tells you where you are on the clock long before a leak does. These areas go first, in roughly this order:

The ridges and hips. The cap shingles running along the peaks and down the hips are the hardest-working pieces on the roof. They sit at the highest point, where wind accelerates over the peak and pulls up on both sides. They get full sun all day with nothing shading them, and they heat and cool harder than anything else up there. They're also bent over the ridge, which stresses the material where it folds. Add it up and caps commonly wear out well ahead of the field shingles below them.

Two things make it worse. Caps cut from flat field shingles instead of purpose-made hip-and-ridge pieces crack at the bend, especially if they were bent cold. And the sealant strips at the ridge give up sooner than those in the field, so the edges lift, wind gets underneath, and the next one lifts after it.

The south and west slopes. Afternoon sun does the most damage. On many homes the south or west slope is visibly further along than the north side of the same roof, same age, same material.

The edges. Eaves, rakes, and anywhere the covering ends. Uplift is strongest at edges and corners, which is exactly why the wind mitigation form cares so much about them.

Valleys. They carry the most water and collect the most debris, so they wear faster and hold moisture longer.

Around every penetration. Boots, vents, and flashings age on their own schedule, usually shorter than the roof's.

Here's the practical part. Worn caps alone are a repair, not a death sentence. Caps can be replaced without touching the rest of the roof, and on a roof with years left that's money well spent. But when the caps are failing and the field shingles are losing granules and curling, those two together say the whole covering is at the end, not just the peak.

So when you look at your roof from the ground, start at the ridgeline. It's the first chapter of the story the rest of the roof is about to tell.

📊 Florida Service Life at a Glance

Judging what's left starts with knowing what's normal here. These are the ranges we see in Central Florida, pulled together from the whole series. Each line reads: covering — typical service life · the age to start watching.

• 3-tab asphalt shingle — 12 to 18 years · 8 years

• Architectural shingle — 15 to 20 years · 10 years

• Concrete or clay tile (the tile itself) — 25 to 50+ years · the tile outlives the roof

• Underlayment beneath tile (felt) — 15 to 25 years · 15 years

• Metal, exposed fastener — 25 to 30 years · 10 years, at the screws

• Metal, standing seam — 40+ years · 25 years

• Modified bitumen (flat) — 10 to 20 years · 8 years

• TPO single-ply (flat) — 15 to 20 years · 10 years

• Built-up tar and gravel — 15 to 20 years · 12 years

Two notes on reading this table. "Start watching" is not the point where something is wrong; it's the age where an annual look pays for itself and where budgeting should begin. And these ranges move several years in either direction depending on sun exposure, attic ventilation, and how well the roof was installed in the first place. A shaded, well-vented roof installed correctly outlives a baking, poorly vented one by years.

Remember too that the fully adhered underlayments going on roofs today don't have a Florida track record yet, so the felt numbers above are what we know, not what a modern membrane will do.

🧮 The Money Math

The simplest way to compare options is cost per remaining year.

Take a repair quote and ask the inspector or roofer, honestly, how many more years the roof should give you. Divide the repair cost by those years. Then take the replacement quote and divide it by the expected life of the new roof. Comparing those two numbers won't make the decision for you, but it stops the "it's cheaper to repair" reflex from making it for you.

A few patterns that come up over and over:

• A young roof with one failure: repair, almost always.

• An old roof with one failure: the repair is a stopgap. Fine if you need time to budget. Just plan the replacement.

• An old roof with repeated repairs: add up what you've spent over three years. People are often startled by the total.

• A roof you can't insure: replacement, even when it isn't leaking. An uninsurable roof threatens the whole house.

• A roof at the midpoint with a bad slope: sometimes a single-slope replacement makes sense. Ask whether it can be done without creating a visible mismatch or a weak tie-in.

🏛️ When Insurance Makes the Decision

From Lesson 1: Florida law protects you from being refused coverage because of roof age alone, and past 15 years you have the right to an inspection showing 5 or more years of useful life. But that's a floor, not a guarantee of good terms.

Four ways insurance forces the issue:

• An insurer won't write or renew without a new roof, and the inspection doesn't support five more years.

• Your policy pays roof claims on a schedule rather than replacement cost, so a storm loss leaves you covering most of the bill yourself.

• The premium difference between an old roof and a new one, combined with better wind mitigation answers, changes the math on replacement.

• The 25% rule. On a roof built before the 2007 code took effect in March 2009, storm damage to more than a quarter of it can require the whole roof to come up to current code.

If a storm is involved, mind the clock. Notify your insurer within one year of the date of loss for a new or reopened claim, 18 months for a supplemental. Those windows shortened in 2022, and missing them is final.

📄 What a Good Roofing Proposal Looks Like

Once you're replacing, the proposal tells you a lot about the roofer. A thorough one spells out:

• Tear-off or recover, and how many existing layers are coming off

• The underlayment, by product name and type, and how it's attached. After Lesson 2 you know why this matters more than the shingle brand

• Deck re-nailing to current code, which is cheapest while the covering is off and improves your wind mitigation

• Rotten decking: a per-sheet price, since nobody knows what's under there until it's open

• All new flashings, drip edge, and pipe boots, every one of them

• Ventilation, and whether any is being added or changed

• The permit, stated as included, pulled by the contractor

• Product approval numbers for the covering and the underlayment, which you'll want for your next wind mitigation inspection

• Two separate warranties: the manufacturer's on materials and the contractor's on workmanship, with the length of each

• Payment schedule, with a reasonable deposit and the balance at completion

• License and insurance, verifiable, including workers' compensation

Red flags: a one-page price with no scope, pressure to sign today, a large deposit up front, no permit mentioned, and anyone who shows up after a storm offering to "handle the insurance" for you.

🚩 About Storm-Chasers and "Free Roof" Offers

After every Florida storm, the door knocking starts. Some of those companies are fine. Some aren't, and the pitch is usually the same: your roof is damaged, the insurance will cover it, sign here and we'll take care of everything.

Two things to know:

• You can no longer sign your claim benefits over to a contractor. Florida banned assignment of benefits for property insurance policies issued on or after January 1, 2023. An attempt to assign post-loss benefits under such a policy is void and unenforceable. If somebody hands you paperwork that does that, something is wrong.

• An inflated or invented damage claim is fraud, and it's your name on the claim, not the salesman's.

The safer order is: get your own inspection, find out what's actually damaged, then decide whether a claim makes sense, then hire the roofer.

🏷️ If You're Selling an Older Roof

A roof past its service life will come up, if not from the buyer's inspector then from the buyer's insurance agent. Pricing it into the listing up front costs less drama than renegotiating after an inspection report lands.

Your options are the familiar three: drop the price, offer a credit at closing, or replace it before you list. Replacing it generally produces the smoothest closing, because the buyer's insurance quote stops being a question mark.

Either way, the paperwork travels with the house. Permit, contractor invoice, product approvals, warranty documents, and the wind mitigation form. Gather them before you list, and hand them over at closing.

🏡 For Buyers: Why the Roof Is the Most Important Thing on the House

If you're shopping for a home, let me say this as plainly as I can. The kitchen gets the attention. The roof decides the outcome.

Here's why it belongs at the top of your list, with the biggest reason first:

1. It's the largest unavoidable expense you'll inherit. Every roof has a date with a crew and a dumpster. Buy a house with a 16-year-old shingle roof and you haven't avoided that cost; you've just agreed to pay it sooner than the seller would have.

2. A failure doesn't stop at the roof. When water gets in, it ruins insulation, ceilings, drywall, flooring, cabinets, and your belongings. A catastrophic failure during a storm can mean a gutted interior, a mold remediation, and a place to live while it's repaired. The roof itself is often the cheapest part of that bill.

3. It decides whether you can insure the house at all. Everything from Lesson 1 lands here. A roof an insurer won't write isn't a maintenance issue; it's a closing problem.

4. It decides how a future claim gets paid. Older roofs often come with a payment schedule rather than replacement cost, so the storm you were insured for still costs you most of a roof.

5. It affects what you pay every year. Roof age, covering type, deck attachment, and opening protection all feed the wind mitigation credits from Lesson 3. Two identical houses can carry very different premiums.

6. It's the hardest thing to fix after you own it. A dated kitchen is a choice. A failed roof is an emergency with a line of trucks out front and no leverage on your side.

7. It sets the clock on everything underneath. Decking, insulation, and framing all depend on the roof doing its job. A roof that's been leaking quietly for years has already spent some of your structure.

8. It's your best negotiating item. A documented roof condition is a concrete number at the table. "Needs paint" isn't; "has four years left on a 20-year roof" is.

9. Material determines your future bill, not just today's look. A tile roof and a shingle roof are not the same financial commitment, as the list below shows.

10. It's the thing a seller is most likely to have patched rather than fixed. Fresh sealant at a flashing, one new boot, a few replaced tiles. These are easy to spot and easy to miss, and they tell you a story about the roof's last few years.

What that future roof will cost you

Here's the part most buyers never run the numbers on. You're not just buying the roof; you're buying its replacement. Florida planning ranges for a typical 2,000 square foot roof in 2026. Each line reads: covering — typical replacement cost · how often you'll pay it.

• Architectural asphalt shingle — $10,000 to $18,000 · 15 to 20 years

• Concrete or clay tile (full replacement) — $20,000 to $40,000+ · 25 to 50 years

• Tile re-lay (same tile, new underlayment) — typically well below a full tile replacement · 15 to 25 years

• Metal, exposed fastener — $14,000 to $25,000 · 25 to 30 years

• Metal, standing seam — $20,000 to $45,000 · 40+ years

• Flat / low-slope sections — $4 to $10 per square foot · 10 to 20 years

These are planning ranges, not quotes. Your actual number moves with roof size, pitch, complexity, tear-off, and whatever the deck looks like once it's open. Prices have also climbed steadily in Florida, so a roof you'll replace in twelve years will not cost what it costs today.

Run the arithmetic before you fall in love with the house. A tile home with original underlayment at year 22 carries a different future bill than a shingle home re-roofed last year, even if both inspect the same today. That difference belongs in your offer, not in a surprise five years from now.

❓ Questions From the Back Row

"My roof is 17 years old and not leaking. Do I replace it?"

Not necessarily today. Get an inspection, document what life it has left, and check what your insurer says at renewal. But start budgeting, because at 17 you're spending borrowed time.

"Three roofers, three different answers. Who do I believe?"

Get it looked at by somebody who isn't selling you a roof. That's part of what an inspection is for, and it's why a roofer and an inspector are different jobs.

"Can I just put new shingles over the old ones?"

It's sometimes allowed, within code limits on existing layers and condition. It's also how a bad deck gets buried out of sight, and it gives up the chance to re-nail the deck and add a sealed underlayment. Ask what it costs to do it right before taking the shortcut.

"The roofer wants half down. Normal?"

A deposit is normal. Half before any material arrives is steep. Ask for the payment schedule in writing and tie payments to milestones.

"How do I know the new roof was done right?"

The permit gets a final inspection from the county, which is a good baseline. Keep the permit record and ask for photos of the deck and underlayment before the covering went on, since nobody can see that layer afterward.

🧰 Getting Every Year Out of the Roof You Have

Most of this lesson has been about the decision. Let's end somewhere more useful: what actually buys you time while the roof is still inside its service life.

None of this makes an old roof new. What it does is keep a roof from dying early, which is what usually happens. A 20-year roof that fails at 13 rarely wore out; something went unattended.

• Fix the small things the week you learn about them. A cracked pipe boot, a lifted cap, a loose flashing, three slipped tiles. These are cheap today and expensive once water has been working on the deck for a season.

• Replace worn ridge and hip caps. As we covered, the caps go first. Replacing them on an otherwise sound roof is a repair, and it protects the peak where uplift is strongest.

• Keep the surface clear. Leaves and pine needles in valleys dam water and hold moisture against the covering. Clear them, and keep gutters flowing so water isn't backing up under the edge.

• Trim back overhanging limbs. Branches abrade the covering in wind, drop debris, hold shade and moisture, and give rodents a bridge to your roof.

• Mind the attic. Ventilation is what keeps heat and moisture from cooking the underlayment from below. A poorly vented attic shortens the life of everything above it. While you're up there, make sure bath fans vent outside and not into the attic.

• Stay off it, and keep others off it. Every trip across a roof costs it something, and on tile or aging shingle, walking is damage. When a tech needs to go up, ask them to work from the ladder or walk where the roofer tells them to.

• Look after every storm. A quick check at the ridge, the edges, and the attic catches displaced caps and lifted edges while they're still a small repair, and it starts the clock knowingly if a claim turns out to be warranted.

• Have it looked at once a year, and keep what you learn. A short written record of the roof's condition each year is the single best way to know where you are on the clock, and it's exactly the documentation an insurer asks for once your roof passes 15.

Do those things and you'll get the top end of the ranges above instead of the bottom. That difference is often five years, which on a roof is real money.

🚌 Field Trip — Class Dismissed

Pull together your roof folder, one place for all of it: the permit date and year of your last roof, the contractor's invoice and warranty, any product approval sheets, your most recent wind mitigation form, and your insurance declarations page.

If you can't find some of those, that's useful information too. The permit record is public and your agent can send the rest. Having that folder ready turns the next roof decision, or the next storm, from a scramble into a phone call.

Next class: taking care of the roof you have. Those black streaks and what they really are, why pressure washing ruins a roof, the maintenance that actually buys you years, and what quietly voids your warranty.
