If your concrete tiles look fine but you’re seeing ceiling stains after rain, the felt underlayment beneath may have failed. That’s the hidden problem we find on most Stevenson Ranch homes we inspect. Call (877) 367-1429 - a live person answers, even at 2 a.m. during a Santa Ana wind event.
Why Ridgeline Roofing Co. of California Is Stevenson Ranch’s Preferred Roof Replacement & Installation Company
We’ve been climbing roofs since 1984 - over 42 years of standing behind our work, not chasing storms out of town.

Our customers here tend to be longtime homeowners who remember the last contractor who let them down.

Our photo-documented inspections show you exactly what we find on your actual roof, not a generic sales pitch in the driveway. And because we hire local crews and train apprentices into journeymen, the technician who knows your neighborhood’s wind patterns and code requirements is the same one who’ll be back if you ever need us. We’re not the cheapest bid from a truck that won’t be in town next spring. We’re the square deal you do once and never revisit.
Our Roof Replacement & Installation Services in Stevenson Ranch
Tile Roofing
Stevenson Ranch was built with concrete tile roofs almost exclusively, and we’re the specialists those tiles demand. The tiles themselves can last 50 years, but the felt underlayment beneath them was rated for 15-20 years. That gap creates the dominant roofing problem in 91381: tiles that look intact while water streams through degraded felt every winter. We remove, inventory, and reinstall salvageable tiles, replace the underlayment with modern, fire-rated materials, and reset ridge caps with fresh mortar that can handle Newhall Pass wind cycles. On a Spanish-style home on Pico Court, we found the original 2002 concrete tiles intact but the felt underlayment so brittle it tore at a touch, and ridge-cap mortar was cracked from Santa Ana gusts. We removed all tiles, installed GAF WeatherWatch underlayment, and replaced the ridge caps with fire-rated mortar, meeting Very High Fire Hazard Severity Zone code.

Full Roof Replacement
When underlayment has failed across the entire field, when tiles have lifted in repeated wind events, or when your 1998-built home is simply at end-of-life alongside every neighbor on your street, a full replacement is the honest recommendation. We handle complete tear-off, deck inspection and repair, underlayment installation, and tile or shingle replacement. Because Stevenson Ranch homes were built in such a compressed window, we often coordinate multiple replacements on the same block - saving homeowners money on material delivery and permitting efficiency. Every full replacement we perform in Stevenson Ranch uses Class A fire-rated assemblies, mandatory in this Very High Fire Hazard Severity Zone.

New Construction Roofing
While Stevenson Ranch itself is largely built out, we handle new construction and major addition roofing throughout the Santa Clarita Valley, including custom homes on remaining hillside parcels. We spec assemblies that exceed minimum code for wind resistance and fire rating - because Newhall Pass conditions punish the minimum standard. Our relationships with GAF, CertainTeed, and Owens Corning let us source materials without the delays that plague smaller operators.

Asphalt Shingles & Metal Roofing
Some Stevenson Ranch homeowners moving from elsewhere prefer the look and cost profile of architectural shingles or standing-seam metal. We’re authorized installers for both, and we’ll tell you straight whether your HOA or the local aesthetic makes either practical. Shingle roofs in Stevenson Ranch run lower than tile - typically $12,000-$18,000 - but won’t match the Mediterranean character that defines the community. Metal costs more upfront but delivers exceptional wind and fire performance. We’ll walk you through the trade-offs without pushing either way.

Trusted Brands We Service in Stevenson Ranch

Because we maintain inventory relationships with regional distributors in the Santa Clarita Valley, we don’t leave you waiting weeks for underlayment or ridge vent materials. Our technicians are manufacturer-trained on each system - not generalists guessing at proper fastening patterns for concrete tile in high-wind zones. The materials we specify for your roof are the materials that arrive on your roof. No substitutions, no surprises.
Common Roof Replacement & Installation Problems We See in Stevenson Ranch Homes
- Silent underlayment failure on concrete tile roofs. The original felt installed during the 1995-2005 building boom has reached end-of-life across Stevenson Ranch. Homeowners see no visible tile damage but discover water stains on ceilings after the first serious winter rain. We find this on inspection after inspection in the 91381 ZIP.
- Cracked ridge-cap mortar from Santa Ana wind cycles. Newhall Pass funnels high-velocity gusts directly onto Stevenson Ranch ridge lines. Over 20-plus years, that vibration and flexing cracks mortar joints. Open ridge caps let water in during storms and embers in during fire events - a dual failure mode we flag constantly in this WUI zone.
- Improperly fastened tiles lifting in wind events. Early construction sometimes relied on inadequate fastening for the wind loads this area actually experiences. Once tiles start lifting, the pattern spreads. Partial repairs fail because adjacent tiles are the same age, with the same brittle underlayment, facing the same wind exposure.
- Code compliance gaps on re-roofs. Many homeowners don’t realize that any permitted re-roof in Stevenson Ranch’s Very High Fire Hazard Severity Zone must meet current Class A assembly requirements. We handle the permitting, the ember-resistant underlayment specification, and the fire-rated ridge vent details so your replacement passes inspection the first time.

FAQs - Roof Replacement & Installation in Stevenson Ranch
The tiles are not your waterproofing layer - the felt underlayment beneath them is, and in Stevenson Ranch’s 1995-2005 building stock, that felt is hitting 20-30 years of age simultaneously. We’ve inspected homes where tiles appeared nearly new but underlayment crumbled at finger pressure, allowing extensive interior damage. A full replacement lets us strip to the deck, inspect for hidden damage, install modern fire-rated underlayment, and reset tiles properly for the next 30 years. Call (877) 367-1429 for a free inspection - we’ll show you photos from your actual roof.
Yes. Los Angeles County mandates Class A fire-rated roofing assemblies on any permitted re-roof in Stevenson Ranch. This affects your underlayment choice (ember-resistant materials required), ridge vent specification, and deck protection details. We handle all permitting and code compliance as part of our standard process - not as an upsell. Our estimates include only assemblies that will pass inspection in this zone.
Cracked ridge-cap mortar is never cosmetic in Stevenson Ranch. Those cracks admit wind-driven rain during winter storms and embers during fire season - and because your home backs up to brushy hillsides in a WUI zone, both risks are elevated. We replace cracked ridge caps with fresh, fire-rated mortar as part of any re-roof, and we can address isolated ridge-cap failure on otherwise sound roofs if the underlayment beneath is still viable. Call for an inspection to determine which situation applies to your home.
Newhall Pass creates a geographic funnel that accelerates Santa Ana winds before they hit Stevenson Ranch. Sustained high-velocity gusts vibrate ridge caps until mortar cracks, and improperly fastened tiles lift completely, breaking battens and exposing underlayment. We’ve seen wind events cause damage across entire neighborhoods in a single night because the original fastening standards didn’t account for actual local conditions. Proper reinstallation with modern fastening patterns and fresh mortar prevents recurrence.
There can be. Because Stevenson Ranch homes were built in such a compressed timeframe, entire blocks often need replacement within the same 2-3 year window. Coordinating with neighbors lets us batch material deliveries, share dumpster and equipment costs, and streamline permitting - savings we pass through directly. We’ve completed coordinated replacements on multiple streets in the community. If you’re friendly with neighbors who’ve mentioned roofing concerns, have them call us too. We’ll price each home individually but explore every efficiency the grouping allows.
