The Answer Nobody Expects
When a homeowner asks me how long their tile roof will last, I tell them: your tile is good for 75 years. Eagle Roofing, who makes the tile we install, rates their concrete tile for 75 years, and I believe them. I have walked on tile from the 1970s that still looks ready for another 30.
So why do tile roofs leak?
The Bottleneck Is the Paper
Because your roof is not just tile. Under those tiles is a waterproofing layer we call underlayment, and that layer is what actually keeps water out of your house. The tile takes the sun, the wind, and the hail. The underlayment does the sealing. And underlayment does not live anywhere near 75 years.
Here is the part that surprises people. On lift and relays across Riverside, Eastvale, and Yorba Linda, we have lifted tiles on houses built in the 1980s and found the original underlayment still under there. Forty year old paper, dried out, cracked, done. The tile above it looked great. The paper below it was the whole problem.
The Honest Fix
That is why the honest fix for most aging tile roofs is not a new roof. It is a lift and relay: we lift your tiles, replace the worn underlayment with a modern system, and relay your same tiles properly secured. You keep the 75 year product you already paid for and replace the part that actually failed.
Your Underlayment Choices
On underlayment, you have real choices, and we walk you through them. PSU-30 is a 30 year peel and stick underlayment with an asphalt barrier that seals around every nail and penetration. UDL-50 is a 50 year synthetic. For most roofs, PSU-30 is the pick I recommend, because that self-sealing asphalt layer protects the roof in the places where trouble starts. It is the same reasoning I would use on my own house.
The Takeaway
If your tile roof anywhere in the Inland Empire, from Rancho Cucamonga to Fontana to Riverside, is 20 years or older, do not wait for the ceiling stain. Have someone lift a few tiles and look at the paper. The tile will be fine. It is what is underneath that decides everything.
