Frequently Asked Questions - Roofing
Straight answers to the questions Los Angeles homeowners ask us most about roof repair, replacement, and cost. If you don't see your question here, call (743) 200-8347 and our team will talk it through with you.
Pricing & Cost FAQs
A full roof replacement in Los Angeles typically runs $8,000 to $25,000 depending on size, pitch, material, and tear-off work. A standard asphalt shingle roof on a 1,500-square-foot single-story home usually lands between $9,000 and $15,000. Tile and standing seam metal push higher. Your exact number depends on access, decking condition, and whether the old roof comes off or gets a layover. Every Mercer Roofing job gets a written, line-item price before any work starts, so you know the number before you commit. Call (743) 200-8347 for a free estimate.
Most roof repairs in Los Angeles fall between $350 and $1,800. A small leak around a vent or flashing repair usually costs $350 to $700. Replacing a section of damaged decking or repairing a sagging area runs $800 to $1,800. The variables are how far the water has traveled, how many layers are on the roof, and whether the underlayment needs replacement. We put every repair price in writing before work starts. Call (743) 200-8347 and we'll send someone to look at it.
A standard roof inspection in Los Angeles costs between $150 and $400. Some companies waive the fee when you move forward with repair work. After heavy rain or wind, inspections are the fastest way to confirm whether a leak is active or old staining. At Mercer Roofing, the written estimate is free, and if we find something, you'll see it in the report with photos. Call (743) 200-8347 to schedule one.
Los Angeles roof costs reflect three local realities: seismic code requirements for fastening and decking, steep access on hillside and canyon homes, and the cost of disposing old roofing in LA County's waste system. Homes in areas like Silver Lake, Echo Park, and Mount Washington often have limited staging space, which adds labor time. Materials have also risen steadily across California. A written, itemized quote will show you exactly where the money goes. Call (743) 200-8347 for your free estimate.
Compare line items, not totals. A fair quote lists materials by brand and type, tear-off and disposal, underlayment, flashing, permits, and labor as separate costs. If a quote is one number with no detail, ask for the breakdown. In Los Angeles, permits for roof replacement run around $300 to $600 depending on the city, and a quote that skips permits is not doing you a favor. Mercer Roofing provides written, line-item pricing on every job. Call (743) 200-8347 for a quote you can actually read.
Service & Process FAQs
We start with a full inspection and written estimate. Once you approve the price, we pull permits if the scope requires them, then schedule the job. The crew removes the old roof in most cases, repairs any damaged decking, installs new underlayment, then the roofing material. Flashing and ventilation get addressed at the same time. A typical Los Angeles home takes three to five working days. You'll know the plan before day one. Call (743) 200-8347 to schedule your free estimate.
Most Los Angeles roof replacements take three to five working days. Tile and slate run longer, sometimes a full week or more. Weather, permit timing, and how much decking needs replacement affect the schedule. We'll give you a timeline in writing before the crew badges in at the door.
No, you don't need to be home. Most homeowners in Los Angeles go about their day while we work. You'll want to be available by phone if we find decking damage that changes scope, but that's handled with a call and a written change order. The crew will let you know the plan in advance.
If you have an active leak, we'll secure the area with a temporary covering as part of the emergency response, then schedule the permanent repair. A tarp is not a fix; it buys you time and prevents further interior damage. Call (743) 200-8347 and our team will get it covered.
Yes, our locations handle asphalt shingle, concrete tile, clay tile, and flat roofing systems common across Los Angeles, including modified bitumen and single-ply membrane. Homes in the hills lean tile, mid-century builds often have flat sections, and most single-family homes use composition shingles. Tell us your roof type when you call and we'll match you with the right crew. Call (743) 200-8347 for your free estimate.
Brands & Parts FAQs
We install materials from leading manufacturers including GAF, Atlas, and Tamko, depending on what fits the home and the homeowner's budget. Each has different warranty structures, wind ratings, and color lines. We'll walk you through the trade-offs honestly so you can choose with confidence. Call (743) 200-8347 to talk about your options.
Most Los Angeles homeowners choose asphalt shingles for value, with concrete tile as the premium option. Both handle the dry heat well. Flat or low-slope sections need membrane systems rather than shingles. The right answer depends on your roof's pitch, the home's architecture, and your budget. We'll explain what fits your house. Call (743) 200-8347 for a free estimate.
A properly installed GAF or Atlas architectural shingle roof in Los Angeles typically lasts 25 to 30 years. Tile roofs can last 40 to 60 years. The real difference is installation quality, ventilation, and sun exposure. South-facing and west-facing slopes in Los Angeles weather faster than shaded northern slopes. Call (743) 200-8347 to talk about what's on your roof now and what it's rated for.
Licensing & Insurance FAQs
Every pro working under the Mercer Roofing name is required to hold the license and insurance their state requires, including workers' compensation coverage. That matters for your protection. If someone is hurt on your property and the roofer isn't properly covered, that can become your problem. We make sure it isn't. Call (743) 200-8347 with any questions about coverage.
Yes, most Los Angeles roof replacements require a permit, and that includes the many separate cities within LA County. We handle the permit paperwork if the scope calls for it and make sure the work passes inspection. A written quote will show the permit line item clearly. Call (743) 200-8347 to ask about your home's specific requirements.
In most cases, no, and we won't. Los Angeles building departments expect roof replacements to be permitted and inspected. Skipping the permit can complicate a future home sale and, in some cases, invalidate the material warranty. Every Mercer Roofing location handles permits as part of the job. Call (743) 200-8347 and we'll look up what applies to your property.
Emergency & Response FAQs
Roof work in active rain is dangerous and generally not effective, but we can secure the source with a temporary covering to stop interior damage, then return when the roof is dry to complete the permanent repair. The goal is to stop water coming into your living space, and we can do that today if conditions allow. Call (743) 200-8347 and a coordinator will connect you with the local team.
An active leak that's reaching your interior, storm damage that's left the home exposed, or a roof that has partially collapsed counts as an emergency. If water is coming in or the structure is compromised, don't wait. Call (743) 200-8347 and our team will talk you through the next step.
Our phone line is staffed Monday through Sunday, 7:00 AM to 7:00 PM. A coordinator will take your information and connect you with the local team that covers your address. From there, the crew will work your job into the schedule as quickly as conditions allow. Call (743) 200-8347 and we'll get you connected.
Warranty & Guarantees FAQs
You'll get two layers of protection: the manufacturer's material warranty from brands like GAF, Atlas, or Tamko, and the workmanship coverage from your local Mercer Roofing location. Material warranties vary by product line and installation system, so we'll review exactly what you're getting before you sign anything. Call (743) 200-8347 to ask about the specific materials you're considering.
If the issue is a defect in the material, the manufacturer's warranty applies. If it's an installation issue, the workmanship coverage from your local Mercer Roofing location handles it. We'll come out, diagnose the cause, and make it right. That's the point of putting everything in writing before the job starts. Call (743) 200-8347 and we'll explain the coverage for your roof.
Mercer is an old English surname from the word for a trader known for fair dealing. A straightforward name for straightforward roofing. Mercer Roofing is part of the Threshold Group family, founded in 2000. Every location is independently owned and operated, and every location works to the Threshold Standard. That means background-checked, identity-verified technicians who arrive in clean uniforms and put the price in writing before any work starts. Call (743) 200-8347 to be connected with the team that covers your address.
