Signs You Need a New Roof in Scottsdale, or Just New Felt

By Scottsdale Roof Repairs · September 7, 2026 · 7 min read

A Scottsdale roof does not usually end its life the way roofs do elsewhere. Tile does not curl. Foam does not blow off. The failure is quiet and underneath, and the roof looks the same from the street the day it fails as it did ten years earlier. Here is what to look for on each roof type, from the ground, the attic and the eave, and what it means for the checkbook. Not every one of these signs means you need a new roof; on tile, most of them mean you need new felt.

The age table

Before the signs, the calendar. Original materials, Scottsdale climate:

So a tile roof from 1999 on original felt is at the end, whatever it looks like. A foam roof last coated in 2018 is due. A shingle roof from 2005 is done.

Tile roofs: the signs

Felt visible at the eave is gray and cracked. On many roofs you can see the underlayment at the eave, above the drip edge and below the first course, or at a rake. Black and smooth means life left. Gray, curled, cracked like dry riverbed means finished. A photo on zoom from the ground is enough.

Tile sliding downslope. Field tile that has crept out of alignment, with the courses no longer straight, means the felt has lost its grip or the battens have split. Common on the 1990s production roofs north of the 101.

Leaks only in monsoon wind. The clearest sign there is. Winter rain falls straight and the tile sheds it. Wind-driven rain gets under the tile and only the felt stops it, and if the roof leaks only in July and August the felt is not stopping it.

A second leak in a different place. One leak is a defect. Two, in different places, a year apart, is the felt failing generally.

Efflorescence and moss are not signs. The white bloom on concrete tile is cosmetic. Nothing grows on a Scottsdale roof long enough to matter.

Cracked tile across the roof. Different problem: this is the tile itself failing, from hail, foot traffic or, on some early concrete tile, from the tile aging out. Past 10–15% breakage, a relay stops making sense and a replacement is the conversation.

Foam roofs: the signs

The coating has gone chalky. Rub it with a thumb and it comes off white. The UV protection is spent. This is a recoat, $3,000–$7,000, and it is maintenance, not failure — as long as it happens now.

Gray or yellow foam showing through. The coating has worn off and the foam is being eaten by UV. Pitting starts. Still recoatable if caught within a year or two, with some repair first.

Soft spots. Foam that gives underfoot has taken on water. That area needs cutting out and re-foaming; if it is widespread, the roof is at the end.

Ponding 48 hours after rain. The slope to the scuppers has been lost, or the scuppers are blocked. Fixable, but standing water on foam ages it fast.

Cracks at the parapet. The stucco and the foam move differently. A crack there is where the next leak enters.

Foam roofs in Scottsdale almost never reach the end of their life if the coating schedule is kept. The ones that do were bought by an owner who did not know the schedule existed. The October recoat window is the reminder.

Shingle roofs: the signs

These are the familiar ones, and they apply to the shingle roofs in South Scottsdale and around Old Town.

• Granules collecting at the downspout outlets and bald patches on the sunny slopes
• Shingle edges curling up or cupping, most on the west and south slopes
• Cracked or brittle shingles that break when lifted
• Tabs that have lost their seal and lift in wind
• Nail pops and exposed nail heads
• Ridge cap shingles cracked through

Scottsdale UV takes shingles out from the top. A roof that is 18 years old with the signs above is not a repair.

In the attic

Stained deck, daylight at penetrations, insulation matted from old leaks, and the smell. On a tile roof, a deck with multiple old stains across different areas means the felt has been letting water in for a while, not just at one spot.

What each sign costs to act on

• A single specific defect on a roof with good felt: repair, $300–$1,500
• Failed felt under sound tile: relay, $8,000–$15,000 on most homes
• Chalked coating on sound foam: recoat, $3,000–$7,000
• Shingles done, or tile broken widely, or foam saturated: replacement, $9,000–$22,000 for shingle, more for tile or foam

When it really is the whole roof

Most of the signs above point to a repair, a relay or a recoat. A few point to a full replacement:

• Broken tile everywhere. Once cracked tile runs past roughly 10–15% across the roof, replacing it piece by piece during a relay costs more than it saves.
• A profile nobody makes. If the tile is discontinued and the salvage yards can't match it, a relay has nothing to put back on the damaged slopes.
• Shingles that have given up. Curling, bald patches and brittle tabs on an 18-year-old shingle roof are the end; there is no layer underneath worth keeping.
• Wet foam. Foam that is soft across large areas has water inside it, and recoating would only seal the water in.
• A tired deck. If years of leaks have softened sheathing across much of the roof, the tear-off is happening anyway.

A ten-minute check from the ground

Pick a clear morning. Walk all four sides with binoculars or a phone on zoom and look at the eaves, the rakes, the ridge and the valleys. Photograph anything that looks out of line. On a flat roof, look from a ladder at the parapet for chalky coating, ponding rings and blocked scuppers. Then check the attic for new stains. Put the photos in one album with the date, and repeat the check each spring and after any big storm. Changes between two albums are the most useful thing you can show a roofer.

Common questions

Can a roof look fine and still need replacing?

A tile roof can look perfect and still need new felt, which is a relay rather than a new roof. A shingle or foam roof usually shows its age from the ground or a ladder before it fails.

How long should a new roof last here?

Roughly 18–22 years for architectural shingle, 25–30 years for a relay or the underlayment under new tile, and decades for foam that is recoated every 5–7 years. The tile itself lasts 50 years or more.

Does a new roof need HOA approval?

A relay that reuses the same tile usually changes nothing visible. A new material, a new tile color or a foam recoat in a different color usually needs an architectural submittal first, so ask your HOA before ordering anything.

The mistake to avoid

Waiting for a leak. On a tile roof, the first leak often arrives after the felt has been failed for years, and each monsoon season of wet deck under dead felt adds sheathing repair to the eventual relay. If the roof is at the age in the table above, a roof inspection with lifted tile and a felt photo tells you where you are for less than the cost of the first ceiling repair.
