Frequently Asked Questions

A standard asphalt shingle roof on a 2,000-square-foot home takes two to four days in good weather, with tile or metal roofs adding one to two days. In San Francisco and coastal San Jose, morning fog can delay start times but rarely extends the overall timeline. Santa Clarita and Palmdale's high winds sometimes pause work for safety, especially on steep pitches. We tell you the schedule before we start, and we'll be there when we say. If rain is forecast, we don't begin tear-off until we're certain we can dry-in your home the same day. Your home first: we work in your house the way we'd work in our mother's.

We walk your roof with a camera, photograph every issue we find, and sit down with you to review the images on a tablet, not deliver a scary speech in the driveway. In Woodland Hills and Thousand Oaks, we often find cracked tiles from thermal cycling, while in Los Angeles proper we see more granular loss from UV exposure and poor attic ventilation. You get a written report with photos, a prioritized repair list if needed, and a replacement estimate with options. The inspection is free, takes about 45 minutes, and comes with zero pressure. That's how we've operated since 1984.

You don't need to be home, but we ask that you're reachable by phone and that pets and vehicles are moved away from the work zone. Our crews protect your landscaping, set up magnetic sweepers for nails, and do a final walkthrough with photos sent to you if you're away. In Pasadena and Northridge, where many homeowners are retired and present, we check in at lunch and end of day. In busy San Diego and Santa Ana, we coordinate by text. Either way, you know who's on your roof and what progress looks like. We stand behind it, and that starts with showing our work.

Proper protection prevents damage, and we use plywood runners for driveways, tarps for gardens, and designated dump zones away from sprinkler systems. In Hayward and Santa Clara County's tighter lots, we sometimes use conveyor systems to avoid hauling debris across your property. If you have delicate plantings or a recent paver installation, tell us during inspection and we'll adjust our plan. We've replaced roofs on historic Pasadena homes with century-old gardens and on Santa Clarita hillsides with zero lot lines. Done right means protecting what's underneath the roof too.

We install GAF and CertainTeed asphalt shingles as our standard offerings, with Owens Corning available for homeowners wanting specific color matches or enhanced wind ratings. In hot inland markets like Palmdale and Santa Clarita, we favor GAF's Timberline HDZ with Sta-Green algae resistance, since our intense UV and occasional Santa Ana winds punish lesser products. For coastal Los Angeles and San Francisco, CertainTeed's Landmark PRO holds up well against salt air and moisture. We don't push the most expensive option; we recommend what lasts in your specific microclimate. Named for the ridge, where a roof proves itself, we choose materials that prove themselves too.

Boral clay tiles are worth the premium if your home's architecture demands them or you're in a historic district with material requirements, but they're not necessary for most California homeowners. In Santa Ana and Pasadena, where Spanish Colonial and Mediterranean styles dominate, Boral's authentic clay carries HOA and historical commission approval that concrete alternatives don't. The weight requires structural engineering, which adds $2,000 to $5,000 to most projects. For homeowners in San Jose or Thousand Oaks without style constraints, modern architectural shingles from GAF or Owens Corning deliver comparable lifespan at roughly half the installed cost. We'll tell you when clay is right and when you're paying for appearance alone.

Three-tab shingles are flat, single-layer products rated for 60-80 mph winds and 20-25 year lifespans, while architectural shingles are multi-layer dimensional products rated for 110-130 mph winds and carry 30-50 year warranties. In California, where building codes increasingly require wind resistance and where wildfire ember exposure matters, we install architectural shingles exclusively. GAF's Timberline and CertainTeed's Landmark lines both meet Class A fire ratings and Title 24 cool roof requirements when paired with appropriate underlayment. The cost difference is roughly 20% upfront, but the lifespan and insurance premium benefits repay it. We don't install 3-tab anymore; it's not a square deal for California homeowners.

Yes, we hold a California C-39 Roofing Contractor license, carry general liability insurance, and maintain workers' compensation coverage for every crew member. We're bonded as required for projects over $500. Since 1984, we've never operated without proper licensing, and we provide certificate of insurance documentation to every homeowner before work begins. In Los Angeles and San Diego counties, we also carry additional pollution liability coverage for tear-off debris transport. If a contractor hesitates to show you their license number or insurance certificates, that's your signal to call someone else. We're happy to email ours before you even schedule an inspection.

Verify active C-39 license status on the CSLB website, request a certificate of insurance with you named as additional insured, and confirm the contractor's physical address isn't a mailbox or temporary office. In California's storm-chaser hotspots, especially Santa Clarita and Palmdale after wind events, we've seen out-of-state crews use local motel rooms as "offices" and disappear before warranty claims arise. Ridgeline's office has been in the same county since 1984; our crews are local journeymen, not day laborers picked up at a hardware store parking lot. The Keystone Standard, applied to roofing: 90 days, in writing, no arguing. That promise only works if we're here to answer the phone.

California requires C-39 licensure but not manufacturer certifications, though GAF Master Elite and CertainTeed SELECT ShingleMaster credentials indicate advanced training and access to enhanced warranties. Our lead installers hold both certifications, which matters for warranty registration and for complex installations like steep-slope tile or integrated solar flashing. In San Francisco and coastal zones, some municipalities require additional low-slope or waterproofing endorsements for flat roof work. We maintain those where we operate. Certifications aren't everything, but combined with 40 years in business, they show a company that invests in doing the work Krafted right.

We offer same-day emergency tarping and temporary sealing for active leaks, with permanent repairs typically scheduled within 24 to 72 hours depending on weather and material availability. In Los Angeles and San Diego, our response time averages four hours for emergencies during business hours. For after-hours calls, we have an answering service that reaches our on-call technician, not an overseas call center. In Northridge and Woodland Hills, where sudden Santa Ana wind damage is common in fall, we keep extra tarps and ridge cap stock on our trucks. If water is coming through your ceiling now, call (877) 367-1429 and we'll stop the damage today.

An emergency is any condition where water is actively entering your living space, where structural integrity is compromised, or where a falling hazard exists. Missing shingles alone usually aren't emergencies unless they're exposing a large area and rain is forecast. In Pasadena and Thousand Oaks, we see true emergencies after pine or eucalyptus limbs puncture roofs during storms. In Hayward and the East Bay, it's often wind-lifted flashing at valleys or chimneys. We'll talk you through temporary containment over the phone if needed, then get a crew there fast. Your home first means not leaving you standing in a bucket.

Place buckets under active drips, move furniture and electronics away from water paths, and use a tarp with weighted edges, never nails, if you can safely access the area from inside your attic. Do not climb on the roof yourself, especially tile roofs that crack underfoot or steep pitches common in San Francisco and hillside Los Angeles neighborhoods. If water is near electrical fixtures, turn off the breaker to that area. Then call us. We'll guide you through immediate steps and get permanent protection in place. We've been there when California homeowners needed us since 1984, and we'll be there when we say.

Every full replacement includes the manufacturer's material warranty, typically 30 to 50 years for architectural shingles, plus our written workmanship warranty backed by The Keystone Standard: 90 days, in writing, no arguing. That means if anything we installed isn't right, we come back and fix it with no paperwork, no arguing. Beyond 90 days, our standard workmanship warranty extends to 10 years on full replacements, five years on repairs. GAF and CertainTeed both offer system warranties up to 50 years when installed by certified contractors using specified components, and we register those for you. We stand behind it because we plan to be in California when you need us, not chasing storms in Oklahoma.

Workmanship coverage protects against installation errors: leaks at flashing points, improper shingle fastening, inadequate ventilation causing premature failure, and failures at valleys or penetrations. It does not cover damage from new tree impact, homeowner modifications, or "acts of God" beyond normal weather. In California, we specifically exclude earthquake structural damage but include wind uplift up to the shingle's rated speed if properly installed. Our warranty is transferable once if you sell your home, which matters in Pasadena and San Jose's active real estate markets. We document every installation with photos for warranty claims, so there's never a dispute about what was done.

You call our office, speak to a person who knows your job, and we schedule inspection within 48 hours. If it's our work, we fix it. No third-party adjusters, no "authorized service centers," no forms to mail to a post office box. In 40 years, we've had fewer than two dozen warranty claims per thousand jobs, and we've honored every one. That's the Standing behind it in our K.E.Y.S. code. Compare that to storm-chaser outfits that rebrand every few years and leave warranties worthless. A company that sponsors the county fair and the church roof fund doesn't burn its neighbors. We're local. We answer the phone with a person. That's how you know we'll answer when you need us.

No, a 25-year workmanship warranty from a company that won't exist in three years is worthless paper. In California's volatile roofing market, verify how long the contractor has operated at the same address under the same name. Ridgeline has been here since 1984. Check whether the warranty is backed by insurance or merely a promise. Ours is our own, and our reputation in Los Angeles, San Diego, and every city we serve is the collateral. The longest warranty isn't the best protection; the most trustworthy company is. We've seen "lifetime" warranties from fly-by-night operators who were gone before the shingles weathered. Don't be burned twice.
