What you’re dealing with on an Aliso Viejo roof is often invisible from the street. The concrete S-tile that went up on nearly every home built between 1985 and 2000 looks intact, but the 30-year felt underlayment beneath it is hitting, or has already passed, the end of its service life. That means leaks at valleys and penetrations long before a single tile cracks. You won’t see it. We find it the moment the tile comes off.

Why Mercer Roofing Is Aliso Viejo’s Preferred Roof Installation Company

We built our reputation in Aliso Viejo on one thing: showing up when we say we will, with a written price and a photo-badged crew. Grant Whitlock leads our installation teams, and every technician who steps on your property is background-checked, identity-verified, and uniformed under the Threshold Verified standard. We send you the name and photo of your technician before they arrive. When they ring the bell, they present a photo ID at the door. No wondering who’s outside.

Aliso Viejo homeowners call us because we understand the HOA reality here. The Glenwood, Pacific Ridge, and Westridge architectural committees usually require a color-match submission and a 2 to 4 week approval window before work begins. Contractors who promise a “next week start” lose the job when the HOA delays neighbor notification. We schedule around that window from day one.

Every project includes our 365-Day Done Right Promise in writing. If it’s not right within a year, we make it right. Every repair gets a written guarantee, with a free second visit if it fails. No fine print, no conditions you didn’t see coming.

Tile Roof in Aliso Viejo

Tile Roof replacement in Aliso Viejo means removing aging concrete S-tile, replacing the felt or synthetic underlayment beneath it, and resetting tile over new flashing, drip edge, and fasteners. Because virtually every tract home in this city was built between 1985 and 2000 by the Mission Viejo Company, the original 30-year felt is failing on a synchronized schedule across entire neighborhoods. One house leaks at the valley. Two doors down, the ridge mortar is cracking. The cause is the same.

You need a Tile Roof evaluation when you notice water staining at ceiling corners, granules around downspouts, or damp spots near skylights and chimneys even though the tile itself looks fine from the curb. In Aliso Viejo, a full tile roof tear-off and replacement typically runs $14,000 to $28,000 depending on square footage and decking condition. Underlayment-only replacement, where the tile is removed, reused, and reset, lands between $8,000 and $16,000.

Underlayment and Decking

The felt under your tile is the real waterproofing layer. Tile sheds water, but the underlayment is what keeps moisture out of your attic. On Aliso Viejo homes from the 1985 – 2000 build cohort, that felt has reached its 30-year lifespan even when the tile above still has decades left. We peel the tile, inspect every inch of decking, and write any rot repair into the allowance before we pull a single sheet.

HOA Color-Match and Approval

Aliso Viejo HOAs enforce a narrow palette of approved earth tones, and re-roofing almost always requires a color-match submission before permit. We handle the submission for you, use manufacturer-recognized tile and shingle products from brands like Boral, Atlas, and Tamko, and schedule the start date around the committee’s review window rather than against it.

Roof Ventilation in Aliso Viejo

Roof Ventilation work in Aliso Viejo addresses what happens when a 1990s roof with ridge vents and minimal soffit intake gets a new tile assembly installed over it. Marine-layer moisture from the Laguna Beach coastal influence cycles through tile laps, and without proper airflow that moisture condenses on the underside of the decking and rots it at valleys, penetrations, and fascia edges. Good ventilation is not an add-on here; it determines whether your new underlayment lasts 10 years or 30.

You need ventilation work when bathroom exhaust fans vent into the attic, when upstairs rooms bake in summer, or when you find condensation on the underside of your roof sheathing. In Aliso Viejo, adding or correcting roof ventilation during a re-roof typically runs $900 to $2,800 depending on whether we are adding ridge vents, baffles at the soffits, or a combination. If we find the exhaust fans venting into the attic, we correct that as part of the ventilation scope.

Ridge and Soffit Venting

Most Aliso Viejo homes from the master-planned era have ridge vents but lack adequate soffit intake. That imbalance pulls conditioned air out of the house and leaves dead zones where moisture collects. We calculate net free vent area for your specific roof geometry and add intake where it’s missing.

Santa Ana Wind Exposure

Santa Ana winds funnel through Saddleback Valley with particular force and routinely lift ridge caps or crack mortar at hip ridges. When that happens, the ridge vent and underlayment beneath are exposed to direct moisture. We inspect ridge conditions on every Aliso Viejo job and include ridge repair or replacement in the written quote, not as a late add-on.

Trusted Brands We Service in Aliso Viejo

We install and repair roofs using manufacturer-recognized materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. On Aliso Viejo re-roofs, we most often source concrete and clay tile from Boral, Atlas, and Tamko because they carry the earth-tone color lines this city’s HOAs have approved. We keep local supplier relationships in South Orange County so material runs to Westridge, Glenwood, and Pacific Ridge don’t stall a job waiting on a truck from Riverside. You get the exact tile, the exact underlayment, and the exact color-match submission your HOA will sign off on.

Common Roof Installation Problems We See in Aliso Viejo Homes

• Synchronized underlayment failure: Because Aliso Viejo was master-planned by the Mission Viejo Company between 1985 and 2000, nearly every tract home shares the same 30-year felt underlayment. The city is hitting a concentrated wave of underlayment failures that Laguna Niguel and Lake Forest, with their staggered build-out, never see. Your tile looks fine. The felt beneath it is gone.
• Hidden decking rot at valleys and penetrations: Marine-layer moisture cycles through tile laps and rots sheathing at valleys, chimneys, and fascia edges. You only find it once the tile is off. That’s why every Mercer Roofing contract includes a written allowance for decking repairs, priced per sheet, approved in writing before we replace anything.
• Santa Ana ridge cap damage: Saddleback Valley wind events lift ridge caps and crack hip-ridge mortar, exposing the ridge vent and underlayment to direct moisture. We see this on two-story hip-and-valley geometries throughout Westridge and Pacific Ridge, where the rooflines are more complex and wind loads concentrate at the hips.
• HOA approval delays: Aliso Viejo’s architectural committees often require a color-match submission and a 2 to 4 week approval window. Contractors unfamiliar with this reality promise fast starts and then stall. We schedule around the committee from the first site visit.
