Our Guarantee & Warranty - Mercer Roofing Co Woodland Hills

The Mercer Roofing Co Woodland Hills Guarantee

Here’s what we stand behind in plain terms. When Mercer Roofing Co finishes a roof repair or installation in Woodland Hills, you get a written guarantee on that work, and our 365-Day Done Right Promise backs it. If anything we did isn’t right within a year, we come back and make it right. No fine print gymnastics, no “that’s normal wear” conversation. You get the written price before any work starts, and the written guarantee before we leave. Grant Whitlock has run the crew this way since 2000, and the standard hasn’t softened.

Call (341) 217-2677

That one sentence matters more than most people think. A roof over a Woodland Hills home gets hit with brutal summer sun, Santa Ana wind gusts, and the occasional winter deluge, and the last thing you need after a repair is a callback loop. So we put the promise on paper, sign it, and hand it to you. The guarantee is part of every job, not an add-on you have to ask for. If a repair fails within 365 days, the second visit is free.

What’s Covered

• Workmanship on every repair and installation. If the work we performed fails because of how we performed it, we’re back to fix it at no charge within the guarantee window.
• Material handling with manufacturer-recognized shingle brands. We install and repair using GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral products, and we handle them per the manufacturer’s installation specifications so the product warranty isn’t voided by bad practice.
• Written price before any work starts. The number you approve on paper is the number on the invoice. No change-order surprise after the flashing comes off.
• On-time arrival with a photo ID badge at the door. Every Mercer technician is background-checked, identity-verified, and arrives in a clean, marked uniform under the Threshold Standard. You’ll know who’s walking up your driveway before they ring the bell.
• Job site cleanup before we leave. Nails, old shingles, tear-off debris, lunch wrappers. It’s your property, and we leave it the way we’d want our own homes left after a roofing job.
• Written guarantee included with every repair. You shouldn’t have to remember a handshake promise six months later. It’s on paper, in your hand, before you pay the final invoice.

Our Satisfaction Promise

You don’t have to be a roofing expert to know when something doesn’t feel right, and you don’t need to have the vocabulary to argue about it. If you look at the finished work and something is off, or a leak shows up that traces back to what we touched, you call us. A live person answers the phone at (341) 217-2677, 24/7, and we open a make-it-right file on the spot.

The process is simple. We send a Mercer technician back to your Woodland Hills home to inspect the work. They take photos, walk the roof, and give you a straight answer about what they see. If it’s on us, we schedule the fix. If the issue falls inside the 365-Day Done Right Promise window, that visit and that fix are free. If it’s something outside our work, something the house did on its own or damage from weather we didn’t touch, we’ll tell you that too, and quote you a written price to address it if you want us to. No pressure, no upsell theater.

Grant Whitlock’s view on this is consistent: a roofing company that hides from its own failed work doesn’t last long in a community like Woodland Hills. Word travels fast in the Valley. Standing behind the work is how Mercer Roofing has kept its reputation intact since 2000, and it’s how we’ll keep it. Your roof is the most exposed part of the house, and the crew you hire should be the least fragile part of the transaction.

Licensed & Insured Backing

The paperwork matters, but not for the reason most homeowners think. A license and an insurance policy aren’t decorations on a website. They’re the difference between a roof problem and a financial problem. Mercer Roofing Co is licensed and insured because a roofing crew in Woodland Hills works at height, handles heavy materials, and sometimes discovers rot, bad decking, or wiring that has no business being under shingles. When a professional crew is on your roof, the responsibility for what happens up there falls to the company, not to you.

Every Mercer technician operates under the Threshold Verified standard: background-checked, identity-verified, and dispatched through the Threshold Group quality framework. That framework is contractual, not optional, for every independently owned and operated location. Ask any contractor you’re considering whether they carry the same kind of standing. Then ask to see their proof. We’ll show you ours without hesitation.

How the 365-Day Done Right Promise Works in Real Life

Say we replace a section of flashing near your chimney in March. The first heavy rain of the following January, you see a water spot on the ceiling. You call (341) 217-2677, talk to a person, and we confirm the repair date in our job log. A Mercer tech comes out, finds the flashing pulled loose at the seam, and fixes it. You pay nothing for the second visit because the repair failed inside its one-year window. That’s not a hypothetical. That’s the promise, written down, on every repair we do.

Here’s another one, this time on a full replacement. We install a new asphalt shingle roof on a two-story home off Ventura Boulevard in Woodland Hills. Ten months later, high Santa Ana winds lift a ridge cap we installed. The fix is covered. The homeowner doesn’t have to debate whose fault the wind was. If our installation didn’t hold, it’s on us. That’s the standard we’ve worked under since 2000, and Threshold Group holds every location to it.

Why a Written Guarantee Matters More Than a Verbal One

Talk is cheap in the roofing trade. Any salesperson can say the words “we guarantee it” on the driveway and never put anything in writing. That’s why Mercer Roofing Co puts the guarantee in your hand before the job is done. You receive a written price before work starts, a written guarantee with every repair, and the knowledge that if the repair fails, a second visit is already included in the cost. Nothing is conditional on weather, color, or how busy the season is.

The roofing business in Southern California has its share of storm chasers and discount crews. A guarantee with no paper behind it means you’re relying on a person’s memory of a conversation. A written guarantee means the obligation survives the calendar. That’s the difference, and it’s a difference you’ll notice in how a company behaves when something goes sideways. Mercer Roofing’s guarantee is written, dated, and tied to your specific job file.

What the Guarantee Does Not Cover

Honest guarantees have edges, so here are ours. We don’t cover damage from a new weather event that had nothing to do with our work, a tree limb coming through the decking, a chimney fire, or someone walking on the roof with golf shoes. We don’t cover modifications made to the roof by another contractor after we leave. We don’t cover normal aging of materials over decades, which is a manufacturer warranty conversation, not a workmanship one. We do cover our own work, and we’re unambiguous about that line. If you’re unsure whether something falls inside the promise, call us and ask. A person will answer and give you a direct reply.

How the Threshold Standard Protects the Guarantee

A guarantee is only as good as the person who shows up to honor it. Mercer Roofing Co is part of the Threshold Group family, founded in 2000, and every independently owned location operates under the Threshold Verified standard. That means every technician who arrives at your Woodland Hills home is background-checked, identity-verified, uniformed, and wearing a photo ID badge at the door. Before they pull into your driveway, you’ll know their name and see their photo. The standard exists so the guarantee isn’t just words on a page. It’s a person you can identify, a company you can call, and a promise with a human being behind it.

If you’re planning a roof repair or replacement in Woodland Hills and want the guarantee explained for your specific situation, call (341) 217-2677 and ask for a free estimate. You’ll get a written price, a straight conversation, and no obligation beyond knowing what your roof actually needs.
