Done right the first time
We work across Los Angeles County for homeowners who want the job done right the first time: decks and balconies over living space, tile and flat roofs, and the waterproofing that ties them together, from hillside homes to multi-level houses with decks stacked over living space.
It’s the same company and the same crews that have kept Orange County homes dry since 1945, with one manufacturer’s system on every job, start to finish.
What we do in Los Angeles
Decks & Balconies
Waterproofing, repair and recoats for decks and balconies, including the ones over living space.
Roofing
Tile, shingle and flat roof repair, inspections, coatings and replacements.
Commercial
Roof repair and coatings for commercial buildings, with the same honest assessment we bring to homes.
Hillside and multi-level homes
Many LA homes are built on slopes, with decks hanging off the back and balconies stacked over living space. Water has a lot of places to go on a house like that, and gravity takes it straight into the framing.
We trace the water from where it shows up back to where it gets in, fix the cause, then install a complete system so the deck and the house below stay dry.
If you are planning around a slope: what goes into a roof deck and wood, composite or concrete for your deck.
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 Los Angeles, start to finish
We come up from Costa Mesa for residential and commercial roofing across Los Angeles, from a company in business since 1945. Here’s the full list of roof work we do in Los Angeles.
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 Los Angeles
Do you really come to Los Angeles from Costa Mesa?
Yes. Call 949.374.2628, tell us where the house is and what’s going on, and we’ll set up a free estimate.
Do you charge for estimates?
No. Estimates are free, in writing, after we have looked at the job.
What kind of roofs do you work on?
Tile, asphalt shingle and flat or low-slope roofs: repairs, inspections, coatings and full replacements.
My balcony leaks into the room below. Can you fix it?
Yes. We find where the water is getting in (often the door threshold or the drain), repair any damage under the surface, then waterproof it as one system.
Are you licensed?
Yes. Crank Waterproofing is a licensed California contractor, CA License #1038420.
How much does roofing cost in Los Angeles?
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 a roof be inspected?
Once a year is a good habit, plus after any big storm. Near the coast, salt air wears out flashing and fasteners faster, so don’t stretch it. A quick check costs far less than the ceiling it saves.
Do you offer emergency roof repairs?
Yes. Call 949.374.2628. We’ll help protect the house first, then come back and fix the source properly.
Can you restore an existing roof instead of replacing it?
Often. If the roof deck and most of the roof are sound, a repair, new flashing or a coating can buy you years. We check first and recommend replacement only when repair stops making sense.
Do you work on both residential and commercial properties?
Both. Homes, condos and HOA communities, plus offices, retail and multi-family buildings.
