Some of the oldest homes in Orange County
Santa Ana has neighborhoods going back a century, with Craftsman and Spanish-style homes in places like Floral Park and French Park, alongside mid-century tracts and newer townhomes. Older roofs here are often shingle, tile or flat sections over additions, and each fails in its own way.
Our shop is a few minutes away in Costa Mesa, so getting out for an estimate is easy.
What we do in Santa Ana
Roofing
Tile, shingle and flat roof repair, inspections, coatings and replacements. We show you what we found before we quote.
Decks & Balconies
Waterproofing, repair and recoats for decks and balconies, including the ones over living space. We fix what’s under the coating before we put a new one down.
Waterproofing
Balconies over living space, walkways, stairs and below-grade walls, done as one system from one manufacturer.
Flat roofs and additions
Flat and low-slope sections, often over a porch, garage or later addition, are where a lot of older homes leak. Water sits instead of running off, and the seams and edges give out first.
We repair what’s failed, then apply a coating or new membrane built for low slopes, and we make sure the transition to the main roof is sealed properly.

We don’t build on bad bones.We’d rather lose a bid than put new work on top of an old problem.

Roofing in Santa Ana, start to finish
Santa Ana has everything from older homes to flat-roof commercial buildings, and we work on all of it. Here’s the full list of roof work we do in Santa Ana.
Repairs & leak tracing
Cracked or slipped tiles, worn underlayment, failed flashing. We find where the water is actually getting in and fix that layer, not just the spot you can see.
Inspection & maintenance
A check once a year and after big storms catches small problems while they’re still small. You get photos of what we found.
Coatings & restoration
On sound flat and low-slope roofs, a reflective coating adds years and keeps the building cooler. On tile roofs we can often keep your tile and replace what’s under it.
New roofs & re-roofing
When repair stops making sense, we replace it: tile, shingle and flat roofs, built to code and cleaned up when we’re done.
Commercial roofing
Flat and low-slope roofs on offices, retail and multi-family buildings, scheduled around your tenants.
Emergency & storm repairs

Questions we hear in Santa Ana
Can you repair a flat roof instead of replacing it?
Often, yes. If the surface underneath is sound, repairing the seams and applying a roof coating can add years. We’ll tell you which one your roof needs.
Do you work on older homes?
Yes. We work on homes of every age, and older ones are where an honest look underneath matters most.
Do you work in HOA communities?
Yes. We work with homeowners and HOAs alike, and we’re glad to walk a board or property manager through what we found.
Do you charge for estimates?
No. Estimates are free, in writing, after we’ve looked at the job.
Are you licensed?
Yes. Crank Waterproofing is a licensed California contractor, CA License #1038420.
Do you do roof inspections and maintenance in Santa Ana?
Yes. We inspect, send you photos of what we found, and handle small repairs before they turn into big ones.
How much does a new roof cost in Santa Ana?
It depends on the size of the roof, the material, the pitch, and what we find under it. We come out for free, show you photos of what we found and give you a written estimate, so you’re comparing real numbers, not guesses.
How often should roof coatings be reapplied?
It depends on the system and how much sun the roof takes. Most coatings need a maintenance coat every several years. We’ll give you the manufacturer’s numbers for the system we recommend, and we can put you on an inspection schedule so it gets renewed before it fails.
What’s the difference between a repair and a full replacement?
A repair fixes the area that failed: a leak, a flashing detail, a section of underlayment. A replacement starts over down to the roof deck. If the problems are isolated, repair. If they’re everywhere, replacing is usually cheaper over time. We’ll show you which one you’re looking at.
How quickly can you respond after storm damage?
Yes. Call 949.374.2628. We’ll help protect the house first, then come back and fix the source properly.
Do you work on both residential and commercial properties?
Both. Homes, condos and HOA communities, plus offices, retail and multi-family buildings.
