By The Arizona Roofer – “Done right and monsoon tight.”
Tile roofs are a staple in Arizona neighborhoods — and for good reason. They’re beautiful, long-lasting, and stand up well to our extreme weather. But while the tiles themselves can last 40 to 50 years (sometimes more), the underlayment beneath them doesn’t.
In my decades of roofing across the Phoenix Valley, I’ve seen tile roofs fail long before their time — not because of the tiles, but because of what’s underneath. The good news? With the right care and maintenance, your tile roof can easily last decades longer than most homeowners realize.
Here’s how to make that happen.
1. Schedule Regular Roof Inspections
The biggest mistake homeowners make is assuming their tile roof is “maintenance-free.” It’s not. Regular inspections — ideally once a year, and especially before and after monsoon season — catch small issues before they become big problems.
During an inspection, we look for cracked or displaced tiles, broken mortar, flashing issues, and underlayment wear. Fixing minor issues early can save you thousands later.
2. Keep the Roof Clean
Dust, leaves, and branches don’t just make your roof look bad — they trap moisture and break down materials over time. Keeping the surface clean, especially in valleys and around skylights, prevents premature deterioration.
Avoid pressure washing unless it’s done carefully; too much force can damage tiles or blow away protective granules.
3. Replace Broken or Slipped Tiles Immediately
A single cracked tile can expose the underlayment to UV rays and rain. Once the underlayment starts to dry out or crack, water intrusion is inevitable. Replacing damaged tiles promptly keeps your roof sealed and healthy.
If you notice a few broken tiles after a storm, have a professional replace them right away — walking on tile roofs without experience can cause even more damage.
4. Protect and Maintain the Underlayment
The underlayment is the unsung hero of a tile roof. In most cases, it’s a felt or synthetic barrier that keeps water out. In Arizona, heat and UV rays eventually dry it out, making it brittle. When that happens, it loses its waterproofing ability.
During re-roofing or repairs, upgrading to high-quality synthetic or double-layer underlayment can add decades to your roof’s lifespan.
5. Check Flashing and Roof Penetrations
Flashing around vents, chimneys, and skylights often breaks down faster than tiles. In Arizona’s extreme temperature shifts, metal expands and contracts, loosening the seal. Over time, that can lead to hidden leaks under otherwise perfect-looking tiles.
Annual inspections ensure flashing stays tight and properly sealed.
6. Keep Gutters and Drains Clear
Clogged gutters are more dangerous than most homeowners realize. When debris builds up, water backs up under tiles and saturates the underlayment. That moisture, trapped under heat, breaks down your roof faster than anything else.
A quick cleanout before monsoon season goes a long way toward preventing water intrusion.
7. Trim Overhanging Trees
Branches scraping against tiles can cause micro-cracks that weaken over time. Trees also drop leaves and seed pods that clog valleys and gutters. Trim branches back so they don’t touch or hang over the roof.
8. Recoat or Seal When Needed
Certain tile systems — especially those paired with foam or coatings — benefit from periodic recoating. This improves reflectivity, reduces heat absorption, and helps waterproof vulnerable areas.
9. Avoid Walking on the Roof
Walking on a tile roof without the right technique and equipment can easily break tiles or dislodge them from their proper position. If you need to inspect your roof, use binoculars or a drone — or better yet, call a professional roofer.
10. Plan for Underlayment Replacement at the 20–25 Year Mark
Even with great maintenance, underlayment has a lifespan. Around 20–25 years in Arizona, it’s time for a replacement — even if the tiles still look fine. Replacing the underlayment before it fails prevents leaks, rot, and costly structural repairs.
Think of it like changing the oil in your car — proactive maintenance keeps your roof going strong for decades.
