Mission Viejo roofs wear out from underneath
Most Mission Viejo roofs are clay or concrete tile, and many of them went on when the neighborhoods were built in the 1970s and ’80s. The tile itself can last 50 years or more. What wears out first is underneath it: the underlayment, the flashing at walls and chimneys, and the seals around vents.
That’s where most tile roof leaks start, and it’s why a cracked tile is often a sign of the problem, not the whole problem.
What we do in Mission Viejo
Roofing
Tile, shingle and flat roofs. Leak repair, underlayment replacement, re-roofing, inspections and roof coatings.
Decks & Balconies
Desert Crete waterproof coatings, deck and balcony repair, and railings. Thresholds and flashing get done right before any coating goes on.
Waterproofing
Balconies over living space, walkways, stairs and the places water gets into a house. We find where it’s coming in, not just where it shows up.
Tile roof repair in Mission Viejo: 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 it isn’t. If the underlayment has dried out and cracked, the next storm finds the next weak spot.
We lift the tile, look at what’s underneath, and tell you what we found before we quote the job. If the underlayment is done, we replace it with a synthetic underlayment and re-lay your original tile wherever it’s still sound. That costs far less than a new roof and keeps the look of your street. If it only needs a repair, that’s what we’ll quote.

Roofing in Mission Viejo, start to finish
Mission Viejo tile roofs usually fail underneath, at the underlayment, long before the tile itself gives out. Here’s the full list of roof work we do in Mission Viejo.
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.

Questions we hear in Mission Viejo
Is a cracked tile the whole problem?
Sometimes. On older tile roofs, a cracked or slipped tile is often where the leak shows, while the real cause is worn underlayment or flashing underneath. We check before we quote.
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.
My roof is leaking right now. Can you come today?
Yes. We do same-day emergency repairs in Mission Viejo. Call 949.374.2628 and we’ll help protect the house first, then find where the water is actually getting in.
What does an estimate cost?
Nothing. Estimates are free and come in writing, with photos of what we found.
When can I reach you?
Monday to Friday, 7:00am to 4:00pm, at 949.374.2628. After hours, leave a message and we’ll call you back.
How much does a new roof cost in Mission Viejo?
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 I schedule a roof inspection?
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.
Can a protective coating extend my roof’s life?
On a flat or low-slope roof that’s still sound underneath, yes. A reflective coating seals small cracks, sheds water and keeps the building cooler. If your roof is past the point where a coating makes sense, we’ll tell you that instead.
Are you licensed for commercial roofing?
Yes. Crank Waterproofing is a licensed California contractor, CA License #1038420, and we work on commercial roofs as well as homes.
