Tile roof repair, reset, and replacement in Alhambra.
48% of the housing in Alhambra was built before 1960. On a roof that age, the question is what kind of tile it is: mortar-set clay barrel from that era can't be relaid, and most other tile can.

What's true about Alhambra roofs before we ever get on one.
Public records, not sales copy. Each line links to where it comes from.
What we see on the roofs here: Clay and concrete tile on the Spanish-style homes. Composition shingle on the Craftsman bungalows. Flat and low-slope over additions. That is from our own work in the area, not a statistic.
- Housing. Median year built for housing in Alhambra is 1962. About 68% of it went up before 1980, and 48% before 1960. Single-family homes are 54% of the units. U.S. Census, ACS 2024 5-year

- Fire zone. Alhambra is flat valley-floor terrain and isn't in a Very High Fire Hazard Severity Zone, so a standard Class A roof is typical. Confirm your specific parcel. You can check any parcel on the CAL FIRE hazard-zone viewer. CAL FIRE map
- Climate. California Energy Commission Climate Zone 9. The cool-roof rule applies to flat and low-slope sections only; a pitched tile roof is exempt here. CEC Title 24
What's actually failing when a tile roof leaks.
Broken tile is the most common starting point. Tile is strong against weather and weak under a boot. Someone who doesn't know where to step cracks it, and an AC technician servicing a condenser on the roof is a common cause. Water gets in through the crack.
What happens next depends on what's under the tile. Older tile roofs have felt, tar paper, under the tile. The tile is nailed through it with long nails, and every nail leaves a hole in the felt. When a tile breaks above those nails, water finds the holes. Once water reaches old felt, it doesn't last long, and you can end up with several leaks at once.
We don't use felt. We install self-adhered peel-and-stick underlayment, Polyglass among others. When a nail goes through it, the rubberized asphalt seals around the nail. So if a tile breaks later, the layer under it is still holding the water out.
The other common failure is penetrations: pipes and vents. A lot of roofers seal those with black mastic. Mastic is a temporary patch. It dries out and cracks. We flash the penetration properly and seal it with a roof-rated silicone sealant, made for roofing, not general-purpose caulk.
Your tile, off and back on, with new underlayment between.
We take the tile off and set it aside, replace damaged wood, install new peel-and-stick underlayment, and put your original tile back. Every stage is photographed by drone, so you see the deck before the tile goes back on.

A 10-year workmanship warranty from me, in writing. The manufacturer's warranty on the materials runs 10 to 50 years depending on what goes on your roof; I tell you which applies before you sign. The agreement covers up to 10% wood replacement, with the per-sheet price written in for anything over. California caps the deposit at $1,000 or 10%, whichever is less, and you get three business days to cancel.
Two tile questions we hear in Alhambra.
My tile roof is leaking. Do I need a new roof?
Usually not. Most tile leaks start at a broken tile or a pipe sealed with mastic, with old felt underneath letting the water through. If the tile can be lifted, the fix is new underlayment and your original tile back on. The exception is mortar-set clay barrel tile, which can't be relaid without breaking most of it; a serious leak there means a new roof.
What's under the tile when you relay it?
Self-adhered peel-and-stick underlayment, Polyglass among others, never felt. When a nail goes through it, the rubberized asphalt seals around the nail, so a tile that breaks later doesn't become a leak.
