Irvine homes are reaching the age where it matters
Most of Irvine was built in planned villages from the 1970s on, and much of it went up with concrete tile roofs, stucco and second-story decks and balconies. The tile can last decades. What wears out first is underneath: the underlayment, the flashing at walls and chimneys, and the waterproofing on decks over living space.
In the older villages like Woodbridge, Northwood and University Park, a lot of homes are at that point now.

Tile roof repair: fix the layer that failed
When a tile roof leaks, the quick fix is to swap the broken tile and seal the spot. Sometimes that’s all it needs. Often the real problem is the underlayment that’s dried out and cracked underneath.
We lift the tile and show you what we found. If the underlayment is done, we replace it and re-lay your original tile wherever it’s still sound. That costs far less than a new roof and keeps the look your village requires.
We don’t build on bad bones.We’d rather lose a bid than put new work on top of an old problem.

Questions we hear in Irvine
Do I need a new roof or a repair?
It depends on what’s under the tile. If the damage is in one area, a repair is the right call. If the underlayment has failed across the roof, replacing it and re-laying the tile usually costs much less than a new roof.
Can you match my village’s roof and color requirements?
Re-laying your original tile keeps the roof looking exactly as it did. Where tile has to be replaced, we match it as closely as we can.
Do you work with Irvine HOAs?
Yes. Most Irvine homes are in an HOA, and we’re used to working with boards and property managers alongside the homeowner.
Do you charge for estimates?
No. Estimates are free, in writing, with photos of what we found.
Are you licensed?
Yes. Crank Waterproofing is a licensed California contractor, CA License #1038420.
