Tile re-underlayment: the $20,000 question
This is the most expensive misunderstanding in Florida roofing. Tile lasts 40 to 60 years or more. The underlayment beneath it lasts about 20 to 25. So most “tile roof failure” in Florida is not the tile failing at all — it is the felt underneath, under tile that still has decades left in it. And the two problems have very different price tags.
Full tile replacement — new tile, new underlayment, everything. Roughly $25,000 to $55,000 on a typical 2,500 sq ft Florida home. Clay runs higher than concrete; large complex homes in Davis Islands, Hyde Park or Coral Gables can approach or pass $100,000.
Tile re-underlayment, also called a lift and relay — roughly $18,000 to $35,000 on the same home, or about $600 to $1,170 per square. That is 40 to 60% of the cost of a full replacement, for a roof that performs like new.
What a lift and relay actually involves
Tile is removed by hand, sorted, and stacked for re-use rather than thrown in a skip. Care at this stage is what determines your breakage rate, and breakage is the main variable in the price.
Down to bare deck. This is also when any rotten decking gets found and replaced, and when the deck can be re-nailed to current attachment standards — which, usefully, is one of the features that earns a wind mitigation credit.
Replacing the 1970s or 1980s organic felt that has been quietly decomposing up there. This is the actual repair — everything else is access. In Miami-Dade and Broward, tile underlayment must additionally be tested to the TAS 103 and TAS 104 protocols.
Set with modern foam adhesive plus mechanical fastening, which is a meaningfully stronger attachment than how most older Florida tile roofs were originally installed. Replacement tiles fill in for breakage.
Which one do you actually need?
There are legitimate reasons to replace rather than relay. There are also contractors who simply do not do relays.
Your tile is broadly sound — not widely cracked or spalling. You are seeing leaks or staining rather than visibly failed tile. The roof is 25 to 50 years old. Your tile profile is still available for breakage replacement. You want to keep the look of the house exactly as it is.
The tile itself is badly deteriorated, cracked across many pieces, or spalling. The profile is obsolete and cannot be matched for breakage. There are structural issues with the deck or framing underneath. Or you actively want to change material or appearance.
Ask two questions, in these words. “Is my tile salvageable for a re-underlayment?” And if the answer is no: “Why not, specifically?”
A good contractor will give you a concrete reason from the list above. “We don’t really do those” is not a reason about your roof — it is a fact about their business, and it should send you to get another quote. On a $55,000 job, that one question is worth tens of thousands of dollars.
Get the breakage allowance in writing. Some tile will break during lifting no matter how careful the crew is. A fair contract states an allowance for replacement tile and says what happens if the breakage rate runs over it. Without that clause, breakage becomes a change order on a roof that is already open.
Satellite measurement gives you the squares, pitch and facet count in about thirty seconds — the numbers you need to sanity-check a five-figure tile quote.
