A Scottsdale roof is usually past one underlayment cycle and inside the tile's second. The question is whether yours was ever done — not whether the tile looks good.
The median Scottsdale home was built in 1991, which makes the typical roof here about 35 years old. That number sits in an awkward place. Concrete and clay tile last 40 to 50 years, so the tile is very likely still sound. The underlayment beneath it lasts about 20 to 25 years in Arizona heat — so it has already reached the end of its life once.
That means there are really only two kinds of Scottsdale roof. One had its underlayment replaced somewhere around 2010 to 2016 and is sitting comfortably in the middle of its second cycle. The other never had it done, is now roughly a decade past due, and is either leaking or about to. From the street they look identical, which is exactly the problem.
It is not a small slice of the city either. Nearly half of Scottsdale's housing stock predates 1990 — about 20% went up in the 1980s and another 14% in the 1970s. Those homes are on their second underlayment cycle at best. Meanwhile the largest single cohort, almost a quarter of all homes, was built in the 1990s and is arriving at its first replacement right now.
Scottsdale also has more clay tile and more discontinued premium profiles than the rest of the Valley, which matters when tile breaks during a lift-and-relay and has to be matched. And in the north Scottsdale foothills, desert-contemporary homes bring flat and low-slope sections with parapet walls — a different roof entirely from the pitched tile further south.

Most Phoenix tile roofs are concrete. Clay is a different material, a different install, and a different crew — this is the specialty work.

Tile is a rain shield with a 40 to 50 year life; the underlayment beneath it is the actual waterproofing and lasts about 20 to 25 years here. A 1991 Scottsdale roof has sound tile sitting on a membrane that has already outlived its design life once. The roof looking good from the driveway is not evidence about the layer that matters, and it is the single most expensive misunderstanding in Phoenix roofing.
It adds a step, not usually a delay, as long as it happens first. We photograph the existing tile, identify the profile and colour, and put the submittal together before anything is ordered — because the expensive mistake is buying tile that then gets rejected. Most Scottsdale associations are reasonable about a like-for-like relay, since the tile going back on is the tile that was already approved.
We do, and it is common in north Scottsdale. The two sections have genuinely different failure modes — the tile fails at the underlayment and the penetrations, the low-slope section fails at seams, parapet walls and scuppers. They also often need different materials and sometimes different timing, so the honest answer is usually a prioritised plan rather than doing everything at once.
Almost never. A lift-and-relay reuses your existing tile, so a discontinued profile is only a problem for the small percentage that breaks during removal — and that gap is usually closed with salvage stock or by pulling tile from an inconspicuous elevation and putting the closest available match there instead. Being told a discontinued profile forces a full replacement is worth a second opinion.
