Re-lay if the tile is sound
If most of your concrete tile is intact and can still be matched, a re-lay over new underlayment usually costs less and keeps your home's look. Widespread breakage or a discontinued profile points to full replacement.
The choice between a tile re-lay and a roof replacement comes down to one question: is your tile still good enough to go back on? Here's how to tell, what each option replaces, and what to plan for once the old underlayment comes off.
A tile re-lay keeps your existing roof tile and replaces everything underneath it. The crew lifts the tile course by course, stacks it on the roof or on the ground, and tears off the old underlayment down to the deck. Then the roof is rebuilt from the deck up and your tile goes back on.
A full replacement does all of that and swaps the tile too. The structure, deck work, flashing and underlayment are the same in both jobs. The difference is the cost of new tile and the freedom to change your roof's look.
In a re-lay, the tile you keep is the part of the roof that was never the problem.
Concrete tile is the most common residential roof in the Las Vegas Valley, and it often outlasts the underlayment beneath it. Summer heat and UV dry out older felt until it cracks, and the leak shows up on a roof that still looks fine from the street. That's the situation a re-lay is built for.
A re-lay is usually the right call when:
Because you aren't buying a roof's worth of new tile, a re-lay generally lands at the lower end of tile roof pricing. It also tends to be the simpler HOA conversation, since your roof looks the same when it's done.
A re-lay is also the moment to fix what the original build got wrong. Undersized valley metal, missing drip edge and poorly flashed vents can all be corrected while the tile is off, at a fraction of what they'd cost to reach later.
Reusing tile only saves money if the tile is worth saving. If a lot of it won't survive being lifted and reset, the savings shrink and you're left with a patchwork of old and new pieces.
Full replacement usually makes more sense when:
A material change needs extra care. Tile is much heavier than shingle, so a switch to tile needs a structural check of the framing before anything is ordered. A switch away from tile changes the look of the home and almost always goes through HOA review first.
Clay tile deserves its own note. It's more brittle than concrete tile and breaks more easily during lifting, so a careful on-roof check matters even more before you decide.
If you're on the fence, ask for both options priced side by side. Seeing the re-lay and replacement numbers together, with the same underlayment, flashing and deck allowance in each, makes the trade-off clear. Sometimes the gap is wide enough that a re-lay is the obvious choice. Sometimes it's narrow enough that new tile is worth it for the fresh look and the longer view.
Every re-lay loses some tile. A few pieces crack when they're lifted, and others turn out to be cracked already. How easily those pieces can be replaced often decides whether a re-lay is practical.
New tile in the same profile and color is ordered for the missing pieces. Even then, new tile can look slightly brighter than tile that's spent years in the desert sun, so placement matters.
If none of those leave enough tile to finish the roof cleanly, full replacement is the honest answer. Your inspection report should say how much tile is likely to be lost and where replacements will come from, so the decision isn't left until the roof is open.
Once the underlayment comes off, the roof deck is exposed for the first time in years. If water has been getting past the old underlayment, the sheathing below may be stained, soft or delaminated. That's true for both a re-lay and a full replacement.
Damaged sheets should be cut out and replaced before the new underlayment goes down, because new underlayment over a soft deck won't hold up. Fascia and the wood at the roof edge are worth checking at the same time, since sun damage there is common in Las Vegas.
The best protection against a surprise bill is a per-sheet price written into your contract. Soft spots and sagging you can feel from the roof, or see from the attic, are a sign to expect some deck work. With the price set ahead of time, hidden damage has a known cost, and you aren't negotiating in the middle of the job.
Many Las Vegas homes sit in HOA communities with design rules for roof material, profile and color. A re-lay with your own tile keeps the roof looking the same, which usually makes approval simpler, but many associations still want to know about roof work. Any new or substitute tile needs a submittal with the profile and color for review.
Permits are a separate step from HOA approval. The City of Las Vegas and Clark County building codes exempt some roof covering replacements from permits, but that exemption specifically excludes tile roofing. Expect a permit for tile work and confirm the details with your building department.

Usually, yes. A re-lay replaces the same underlayment, flashing and battens as a new roof, but you reuse your tile instead of buying new. Typical re-lays run [$X–$X] per sq ft. The savings shrink if a lot of tile breaks or has to be sourced to match.
Some breakage is normal, because older tile can crack when it's lifted and some pieces are already cracked underneath. The amount depends on the tile's age, type and condition. Your inspection should estimate it, and your contract should say how replacement pieces will be sourced and priced.
Most homes take a few working days once materials are on site, about the same as a full replacement. Larger, steeper or more complex roofs take longer, and deck repairs can add time. Your written schedule should include the permit and inspection dates.
Not much. Your own tile goes back on, so the color and profile stay the same. Any replacement pieces can look slightly newer at first, which is why they're best placed on less visible slopes. Keeping your own tile also tends to keep the HOA conversation simple.
Often, yes, but clay is more brittle than concrete tile and needs careful handling. Expect a closer inspection of how much tile can be saved and where replacements will come from. If too many pieces are cracked or can't be matched, new tile may be the better value.
