Tile Underlayment Replacement
On most Arizona tile roofs, the tile is not the problem. The underlayment beneath it is — the layer that actually keeps water out, and the one that dries, cracks and fails long before the tile does. We lift and stack your existing tile, replace the underlayment, and set the tile back down.

Your Tile Stays
Sound tile gets reused, which is why this costs a fraction of a full tile roof replacement.
Scoped Honestly
If only two slopes are failing, we quote two slopes — and tell you what the rest has left.
Done To Spec
New underlayment, new flashing and new valley metal installed to the manufacturer's specification, not patched over.

Underlayment is one of the most common roof items flagged during an Arizona home sale. We inspect, price the work line by line, and can complete it before close of escrow.
What The Job Actually Looks Like
Underlayment replacement is disruptive for a few days and invisible when it's done. Here's the sequence, so nothing about it is a surprise.
- 1Step 1
Inspection & Scope
We get on the roof, pull tile in a few places, and photograph what the felt underneath is actually doing. You get a written scope that says which slopes need work now and which don't.
- 2Step 2
Tile Lift & Stack
Tile comes off by hand and is stacked on the roof or the ground. Some breakage is normal on older tile, so the scope accounts for replacements up front rather than as a surprise line later.
- 3Step 3
New Underlayment
Old felt, fasteners and debris come off down to the deck. Damaged decking gets replaced, then new underlayment goes down with new valley metal, flashing and penetration boots.
- 4Step 4
Tile Reset & Cleanup
Your tile goes back down, broken pieces are swapped for matching replacements, and the site is magnet-swept. You get photos of the work under the tile, because you'll never see it again.
Tile Underlayment Replacement FAQs
What is tile roof underlayment?
It's the waterproof membrane between your tile and the roof deck. Tile sheds most of the water and takes the sun, but the underlayment is what actually keeps the house dry. When people say a tile roof is leaking, the underlayment is usually what failed.
How long does underlayment last in Arizona?
Original felt on Valley homes commonly starts failing somewhere around the two-decade mark. Heat, attic ventilation, roof pitch and the quality of the original install all move that number, which is why an inspection beats a rule of thumb.
Do I need a whole new tile roof if it's leaking?
Usually not. If the tile is in decent shape, replacing the underlayment and resetting the same tile fixes the leak and resets the clock on the roof. We'll tell you plainly when a roof is far enough gone that replacement is the better spend.
How much does tile underlayment replacement cost?
It comes down to square footage, pitch, how much tile breaks, how much decking needs replacing, and whether the whole roof or a couple of slopes need the work. We inspect for free and price it line by line rather than quoting a number over the phone.
What drives roof cost in PhoenixCan you reuse my existing tile?
In most cases, yes — that's the point of the job. Expect some breakage on older or brittle tile. We account for replacements in the scope and source matching tile where we can.
What if my tile profile is discontinued?
We source from tile yards and salvage inventory around the Valley, and it's often possible to find a match. When it isn't, we can pull tile from a less visible slope to keep the street-facing elevation uniform and blend the replacements where they show least.
Do solar panels have to come off first?
Yes, if the array sits over the area being re-felted. We handle the removal and reinstall along with the roofing work, so it's one contractor and one schedule.
