Tile Underlayment Replacement in Power Ranch, Gilbert
Gilbert, AZ · Underlayment Replacement · Concrete Tile (Existing) · Timeline: 6 business days · Cost: $12,000 – $18,000
Project Scope
Removal, storage, and re-installation of existing concrete tiles on a 2,400 sq ft roof to replace the original 30-lb felt underlayment that had deteriorated after 18 years. The tiles themselves were in good condition but the underlayment had dried out and cracked in Arizona's extreme heat.
Challenges
Removing and storing 2,400 sq ft of concrete tiles without breakage required careful handling and staging. Approximately 8% of tiles cracked during removal and needed replacement. The roof decking had some areas of moisture damage near the valleys that required patching before new underlayment could be installed.
Solution Applied
We systematically removed all tiles using foam-padded carts to minimize breakage, cataloging tile placement for accurate re-installation. Damaged decking sections were replaced with matched plywood. A premium high-temperature synthetic underlayment was installed with proper overlap and sealed seams. All valley metal and step flashings were replaced. Tiles were re-installed in their original layout with new foam adhesive at all fastening points. Broken tiles were replaced with color-matched units sourced from the original manufacturer.
Materials Used
- High-Temp Synthetic Underlayment
- Replacement Concrete Tiles
- Galvanized Valley Flashing
- Step Flashing
- Tile Foam Adhesive
- CDX Plywood Decking Patches
Frequently Asked Questions
How do I know if my tile roof underlayment needs replacement?
Common signs include granular debris in gutters, water stains on interior ceilings, tiles that slide or shift, and a roof age of 15–20+ years. We recommend a professional inspection if your tile roof is over 15 years old.
Can my existing tiles be reused during underlayment replacement?
In most cases, yes. We carefully remove, store, and re-install existing tiles. Typically 5–10% may crack during handling, and we source matching replacements for any damaged tiles.
How much does underlayment replacement cost in Gilbert?
Tile underlayment replacement in the Gilbert area typically ranges from $5–$8 per square foot, depending on tile type and decking condition. A 2,400 sq ft roof like our Power Ranch project costs $12,000–$18,000.
How long does underlayment last under tile in Arizona?
Traditional 30-lb felt underlayment typically lasts 15–20 years in Arizona's heat. Modern synthetic underlayment can last 25–30+ years and better withstands the extreme temperatures.
Is underlayment replacement covered by insurance?
Underlayment deterioration is considered normal wear and is typically not covered by insurance. However, if underlayment failure is caused by a covered event like storm damage, it may be eligible for a claim.
