What does tile roof underlayment replacement involve in Scottsdale?
Underlayment replacement means the tile is removed in sections and stored, the old water barrier and any soft decking are taken off, new underlayment and flashing are installed, and sound tile is relaid. Tip Top Roofing Service performs this on Scottsdale homes so the roof can be renewed without discarding tile that is still good.

Signs the Layer Under Your Scottsdale Tile Needs Attention
None of these proves the underlayment has failed, but each is a reason to have it looked at.
Stains With No Broken Tile
Ceiling marks that appear while the visible tile looks intact often trace to the layer beneath.
Leaks at Several Spots
Separate leaks in different parts of the roof point to a wide-spread condition, not a single flashing.
Brittle Material Under Lifted Tile
When we lift a tile and the underlayment is cracked, dry or crumbling, replacement is the sensible conversation.
Repeat Patching
A roof that has needed several small repairs over a short time may be telling you about the layer below.
Age of the Original Install
If the roof still has its first underlayment and you do not know its condition, a look under a few tiles is informative.
Soft or Stained Decking
Damp sheathing found during a repair means the water barrier has been getting breached for some time.
How the Work Is Sequenced on a Scottsdale Roof
The sequence protects both the tile and the house.
- We write a free estimate that separates tile handling, underlayment, flashing and any decking repair.
- Tile is removed in manageable sections and stacked on the roof or at ground level, depending on access.
- Old underlayment is stripped, and the deck is checked for soft or stained spots that need to be replaced.
- New underlayment and flashing are installed to the manufacturer's guidance for the tile system.
- Sound tile is relaid, broken pieces are swapped for matches, and the ridge and hips are re-secured.
- We clear the property and walk the finished roof with you.
What Gets Replaced and What Stays
Replaced
Underlayment, failed flashing, cracked or broken tile, and any damaged sheathing found on removal.
Kept
Tile that is sound and fits the roof, which preserves the existing color and profile.
Decided Together
Anything borderline, such as chipped but serviceable tile, is shown to you before we choose.

Scottsdale Tile Underlayment Questions, Answered
What is tile underlayment?
It is the waterproof layer installed on the roof deck beneath the tile. The tile sheds most water, and the underlayment catches what gets past it.
Why can't I see whether mine has failed?
It sits under the tile, so condition is only visible when tile is lifted. That is why we check a few locations before recommending work.
Does replacing it mean replacing my tile?
No. Sound tile is normally kept and relaid. Only cracked, broken or unsuitable pieces are swapped for matching tile.
Will the roof look the same afterward?
Largely yes, because we reuse the existing tile. Replacement pieces are matched as closely as we can source.
How do I know I need this and not a repair?
A repair suits a localized problem. Widespread leaks or brittle underlayment under multiple tiles suggest the whole layer is the issue.
Is a permit needed in Scottsdale?
Requirements depend on the scope of the work. We confirm what applies to your address with the City of Scottsdale before the job is scheduled.
Who handles the paperwork?
We handle the permit steps on projects we perform, under our Arizona contractor license.
What happens if you find damaged wood?
We show you photos, price the repair separately and replace the decking before the new layer is installed.
Can I stay home during the work?
Yes. Expect noise and activity on the roof, but you do not need to leave.
What about rain during the job?
Sections are covered each day with temporary protection suited to the stage, and we plan around the forecast.
Do you reuse the ridge and hip tile?
Where sound, yes. These pieces are removed and reset with the rest, and replaced if they are damaged.
How is the estimate organized?
Tile handling, underlayment, flashing and decking are separate lines so you can compare it with another contractor's bid.
Is the estimate free?
Yes. Our estimate is free. A full roof condition report is a different, paid service.
Does an estimate involve going on the roof?
When it is safe, yes. Tile can crack under foot, so we choose where we walk and photograph what we find.
Can I get an inspection first?
Yes, a roof inspection with a written report is available as a paid service. Some owners book it before asking for pricing.
Will you work with my insurance company?
If storm damage is involved, we can document the condition. Whether it is covered is decided by your insurer.
Can I do this in stages?
Often, by roof section, provided each section is properly tied into its neighbors. We would map the stages with you.
What if the structure cannot carry tile again?
That is rare for a roof that already holds tile, but we check and tell you if the structure needs attention first.
How do I verify your license?
Look up ROC #355034 on the Arizona Registrar of Contractors website. A link is in the sources at the top of this page.
What should I send to get started?
Your address, the roof age if you know it, photos of any stains, and the tile style. Call (480) 877-1643 or use the estimate button.
