Our Guarantee & Warranty - Mercer Roofing Co Los Angeles

The Mercer Roofing Co Los Angeles Guarantee

We put our name on every roof we touch in Los Angeles, and that means something specific: if the work isn’t done right, we make it right. No fine print to decode, no phone tag to reach a decision-maker. Our 365-Day Done Right Promise covers every repair and installation for a full year from the day we finish. If anything fails because of our workmanship, we come back and fix it at no charge. A second visit is always free if a repair doesn’t hold. That’s what a guarantee should be: a promise with a process behind it. Grant Whitlock runs Mercer Roofing Co with one rule that overrides everything else: written price before work starts, written guarantee before we leave. Simple, and it’s kept us busy in every neighborhood from Silver Lake to Woodland Hills since 2000.

What’s Covered

• Workmanship on every repair and installation. We stand behind the labor for 365 days, and we put that in writing on every single job, not just the big ones.
• Parts and materials we install. If a component we supplied fails during the guarantee period, we handle the replacement as part of the make-it-right process.
• Cleanup and jobsite respect. We cover the work area, haul away old materials, and leave your property the way we found it, nails and all debris gone.
• On-time arrival with a human at the door. Your technician arrives in a clean, marked uniform with a photo ID badge, and you get their name and photo before they show up. That’s the Threshold Verified standard.
• Written pricing with no change orders. The price we quote in writing is the price you pay. If we find something unexpected, we stop and talk to you before touching anything else.
• Honest communication about what actually needs work. We don’t sell roofs that don’t need replacing. If a repair buys you years, we’ll say so and give you a written repair price instead.

Our Satisfaction Promise

If you’re not satisfied with the completed work, call us and we’ll walk through it with you. Not a call center. The person who picks up at (213) 521-8272 is someone from our office in Los Angeles, and we answer live around the clock. If something doesn’t look right, if a repair isn’t holding, if clean-up fell short, tell us and we will schedule the visit to inspect it. If the repair failed because of our workmanship, the second visit is free and the fix is free. That’s the whole point of the guarantee: you shouldn’t have to fight for the thing we promised. Grant Whitlock founded this company on the principle that a roofer’s word should be worth the same as a signed contract, and that hasn’t changed in more than two decades of roofing Los Angeles homes.

Licensed & Insured Backing

Every roofer can print a guarantee on a piece of paper. What makes ours enforceable is that we’re a licensed and insured Los Angeles roofing contractor with real accountability behind the promise. Insurance protects your home and property if something goes wrong during the job. Licensing means we answer to the state’s standards for roofing work. And the Threshold Group framework holds us to an additional layer: every technician who walks your property line is background-checked, identity-verified, and reporting under the Threshold Standard. That’s the part most homeowners don’t think about until after a bad experience. The paperwork matters because it’s the difference between a guarantee we can honor and a guarantee we can walk away from. We don’t walk away. Roofs done once and done right, by a crew that badges in at the door.
