Tile Roof Preservation · Palm Beach County, FL

Your tile isn't the problem. The layer beneath it is.

Florida tile roofs rarely fail all at once. Clay and concrete tile can last 50 years or more — but the underlayment beneath it, the actual waterproof layer, cooks out in our sun and rain decades sooner. When it goes, you don't necessarily need a new roof. You need the underlayment rebuilt and your sound tile re-laid — often $20,000–$45,000 less than a full tear-off. Repair-first since 1974.

The Preservation Principle

A tile roof is really two roofs — and only one of them ages out.

The tile is your armor: clay and concrete tile routinely last 50+ years in South Florida. The waterproofing is the felt or synthetic underlayment underneath — and in our heat, UV, and wind-driven rain it reaches the end of its life first, often in 15–25 years. An age-based replacement throws away tile with decades of service left. A condition-based evaluation tells you which layer is actually failing — and under Florida's Roof Age Law (§627.7011), a sound roof with five or more years of remaining useful life can't be condemned on age alone. When the tile is sound and the underlayment is spent, the fix is a tile roof rebuild, not a replacement.

$20,000–$45,000

The typical gap between rebuilding a tile roof's underlayment — re-laying your existing tile over a new waterproof layer — and tearing the whole roof off and starting over.

Why The Underlayment Fails First

The tile shrugs off the weather. The felt underneath takes the damage.

Four things age out a Florida tile roof's underlayment long before the tile itself wears out.

Heat

It cooks from below

Attic temperatures and direct sun bake the asphalt out of felt underlayment, leaving it brittle and cracked. The tile insulates the surface you see — while the layer that matters slowly hardens and fails.

UV

Sunlight reaches it through gaps

Every cracked, slipped, or lifted tile lets UV strike the underlayment directly. Florida's sun breaks it down far faster than the tile manufacturer's lifespan would suggest.

Moisture

It never fully dries out

High humidity and wind-driven rain keep the underlayment damp, and constant wet-dry cycling degrades it. Trapped moisture is also why a failing roof shows up first as attic and ceiling stains.

Water flow

Valleys concentrate the wear

Valleys and transitions funnel water from two roof planes over the same narrow path. That concentrated flow wears the underlayment through years before the open field of the roof shows any age.

Warning Signs

Seven signs the layer under your tile is failing.

You rarely see the underlayment — but you can see what happens when it stops doing its job.

  • Water stains on ceilings or upper walls after rain
  • Damp, discolored, or clumped attic insulation
  • A musty, earthy smell in upper-floor rooms
  • Water stains on fascia or soffit boards
  • Cracked, slipped, or missing tiles
  • Daylight visible through the roof deck in the attic
  • An unexplained jump in cooling bills
Where Tile Roofs Fail First

It starts in the valleys — not across the whole roof.

Tile roofs fail in predictable places. Knowing where lets us preserve the rest.

Valleys

Every drop off two roof planes funnels here. Valleys see the most water and the highest velocity, so their underlayment and metal wear through first — usually years ahead of the rest of the roof.

Transitions & flashings

Where the roof meets a wall, chimney, or changes pitch, sealant and metal flashing age, lift, and separate. These joints are among the most common leak origins on a tile roof.

Penetrations

Plumbing vents, exhaust stacks, and skylights all break the roof plane. The boots and seals around them harden and crack long before the tile field does.

Hips & ridges

Mortar and ridge components loosen with decades of thermal expansion and contraction, opening paths for wind-driven rain to reach the underlayment.

Eaves & drip edges

Wind pushes rain back up under the first courses of tile at the eaves. Worn drip-edge detailing lets that water find the deck and the fascia behind it.

The open field

The broad, flat areas of tile fail last. When the field is sound and the failures are confined to valleys and details, preservation is almost always on the table.

Real Preservation Work

An underlayment rebuild — tile up, felt out, re-laid.

This is what preservation looks like on a real Palm Beach estate: the sound tile lifted and set aside, the failed underlayment replaced, the deck rebuilt, and the original tile re-laid — not a tear-off.

How Preservation Works

From a free inspection to a roof that's been saved, not replaced.

Free, documented inspection

A complete roof inspection with attic thermal imaging. We find where the underlayment is actually failing — not just where you happen to see a stain — at no cost and no obligation.

Condition & useful-life report

A written, photographed assessment of each area of the roof and an honest estimate of its remaining useful life, so the decision is based on documented condition, not age.

Preserve & rebuild

We carefully lift the sound tile, replace the failed underlayment, rebuild valleys and flashings, and re-lay your existing tile. We replace only the tile that's genuinely gone.

Certify when it qualifies

If the finished roof is sound, a signed 5-Year Roof Certification documents its condition and remaining useful life — useful when an insurer or buyer asks.

Preserve or Replace

When a rebuild is right — and when it isn't.

Preservation isn't always the answer. The honest version of this decision rests on condition, not a sales target.

The rebuild

When your tile is sound

If the tile is largely intact and the deck is solid but the underlayment has aged out, we re-lay your existing tile over a new waterproof layer and rebuild the failure points. Usually $20,000–$45,000 less than a full replacement — and it keeps tile that's often hard to match.

Full replacement

When it's truly needed

If the tile itself is widely cracked, the deck is compromised, or the system has genuinely reached the end of its life, a full replacement is the right call. We'll tell you honestly when that's the case — and never one day sooner.

Why Mike McGilvary Roofing

The preservation-first roofer — documentation over demolition.

We inspect the layer that fails

Our whole approach is the opposite of an age-based tear-off. We find the underlayment failures, document them, and preserve every part of the roof that's still sound.

Thermal imaging, signed reports

Attic thermal imaging finds trapped moisture you can't see from a ladder, and every assessment is documented and signed under Florida license CCC1331721.

No sales pressure, ever

If your roof can be preserved, we say so. If it genuinely needs replacing, we show you exactly why — never a replacement you don't need.

Tile Preservation FAQs

Your questions, answered honestly.

Can you really save my tile roof instead of replacing it?
Often, yes. If the tile is largely sound and the roof deck is solid, the fix for a failing roof is usually to replace the underlayment beneath the tile — not the whole roof. We lift the sound tile, rebuild the waterproof layer and the failure points, and re-lay your existing tile. A documented inspection tells us whether that's possible on your roof.
How long does tile underlayment last in Florida?
Typically 15–25 years, depending on the type (older felt fails sooner; synthetic underlayments last longer) and the roof's exposure. The clay or concrete tile on top routinely lasts 50 years or more — which is exactly why so many tile roofs can be preserved rather than replaced.
Is a rebuild really cheaper than a full replacement?
Usually substantially — often $20,000–$45,000 less — because we reuse your existing tile instead of buying and installing an entire new roof. The savings are largest on barrel and specialty tile, which is expensive and sometimes discontinued.
How do you know whether my roof can be preserved?
A documented inspection with attic thermal imaging shows where the underlayment is failing and whether the field tile and deck are sound. If the failures are confined to valleys, flashings, and details — which is the common pattern — preservation is almost always an option.
Do you reuse my existing tile?
Where it's sound, yes. Carefully lifting and re-laying your existing tile is central to preservation, and it's especially valuable for discontinued or barrel tile that would be difficult or costly to match. We replace only the individual tiles that are cracked or broken.
Does a preserved roof still qualify for a certification?
If the finished roof is sound and has five or more years of remaining useful life, it can be documented with a signed 5-Year Roof Certification — the same evidence of condition that may help under Florida's Roof Age Law when an insurer is weighing a roof's age.
