When You Need Full Roof Replacement

Some roofs can be repaired. Others are past the point where patchwork makes sense. Here’s what we see across Austin neighborhoods, from Hyde Park to Mueller to Circle C, that tells us a full replacement is the right call:

• Shingles are curling, cracked, or missing in patches. Once shingles start losing their granule coating after years of Austin UV exposure, water gets underneath. You’ll often see this first on west-facing roof slopes.
• You find granules in your gutters every time it rains. Those granules are the wear layer of your shingles. When they collect in downspouts off Burnet Road or Anderson Mill, the shingles above are nearing the end.
• Water stains appear on ceilings or in the attic after storms. This means the underlayment, the water-shedding layer under the shingles, has been compromised. By the time stains show inside, the decking underneath may already be soft.
• The roof is 20 years old or more. Most asphalt shingle systems in Central Texas last 18 to 25 years, depending on ventilation and how many hailstorms they’ve absorbed. If your home was built in the early 2000s, you’re in the replacement window now.
• Flashing around chimneys, skylights, and vents is rusted or lifting. Flashing is the metal that seals roof transitions. When it fails, leaks follow fast. Replacing flashing piecemeal across an aging roof is usually more expensive than doing a full replacement once.
• A recent storm left hail damage across multiple slopes. If adjusters counted hits on three sides of the roofline, the whole system likely has reduced life even where shingles haven’t failed yet. A full replacement prevents a recurring repair cycle.

If one of these sounds familiar, don’t guess. We’ll inspect and tell you straight whether a repair buys you years or a replacement saves you money long term. Estimates are free, and no work starts without a written price in your hand.

Our Full Roof Replacement Process

Here’s exactly how a full replacement works with Mercer Roofing Co Austin. You’ll never wonder who’s showing up or what happens next.

1. You call and a real person answers. Day or night, weekends included. We ask about your roof, your home’s age, and what you’re seeing. If an inspection makes sense, we schedule it at a time that works for you.
2. Inspection and written estimate. We climb up, document what we find, and give you a written price for the full scope: tear-off, underlayment, shingles, flashing, ventilation, decking repairs if needed. That price doesn’t change unless we both agree in writing to a change.
3. You get your technician’s name and photo before we arrive. Before any work begins, we send you the name and photo of the person who’ll be at your door. They arrive in a clean Mercer uniform and present a photo ID badge. This is part of the Threshold Verified standard every technician is held to.
4. Tear-off and decking inspection. We remove the old shingles and underlayment down to the wood decking. If we find rotted or water-damaged decking, we show you photos, explain what we found, and get written approval before replacing any wood. No surprise add-ons.
5. New underlayment, flashing, and shingles installed. We install new underlayment across the entire roof deck, replace flashing at every penetration and edge, and install shingles from brands like GAF, CertainTeed, or Owens Corning based on what fits your home and budget. Nailing follows manufacturer specs, not shortcuts.
6. Cleanup and final walkthrough. We run magnetic sweepers around the property to catch stray nails, remove all old material from your yard, and walk the roof with you or send photos so you can see the finished work. Then you get your written 365-Day Done Right Promise and repair guarantee.

Why Homeowners Choose Mercer Roofing Co Austin for a Full Replacement

Most roofing companies can install shingles. What separates a roof you trust from a roof you worry about is what happens before and after the install. Here’s what we do differently.

You Know Who’s Coming to Your Door

Before any Mercer technician arrives, you receive their name and photo. When they knock, they’re in a clean, marked uniform and they present a photo ID badge. No guessing. No “somebody from the roofing company.” This matters whether you’re a parent home with young kids, someone who works from home alone, or an older homeowner who wants proof of who’s there. Every technician is background-checked and identity-verified under the Threshold Standard, and each Mercer location is contractually held to the Threshold Verified quality framework. Grant Whitlock, Owner at Mercer Roofing Co Austin, insists on this because a roof replacement should never mean opening your door to an unknown person.

Written Price Before Any Work Starts

You get a written price upfront. Always. That price includes the full scope of work: tear-off, disposal, underlayment, shingles, flashing, and any agreed decking repairs. If something changes mid-project, we stop and get your written sign-off before proceeding. You’ll never see an invoice number at the end that doesn’t match what you approved. This is no-hassle upfront pricing, and it’s not a courtesy. It’s how we do business.

The 365-Day Done Right Promise

Every full roof replacement includes our 365-Day Done Right Promise. If something isn’t done right within a year, Mercer makes it right. That’s not a vague “we stand behind our work.” That’s a written guarantee with a clear timeframe: 365 days. Every repair we perform, whether during the replacement or in a follow-up, also carries a written guarantee. If that repair fails, the second visit is free. This is what certainty looks like in roofing.

Full Roof Replacement Pricing in Austin

Full roof replacement in Austin typically runs $9,800 to $18,500 for a standard single-family home. Smaller ranch-style homes in neighborhoods like Windsor Park or Crestview can fall at the lower end. Larger two-story homes in Westlake or Steiner Ranch run higher. Here’s how that price typically breaks down:

Item	Typical Range in Austin
Tear-off and disposal of old roof	$1,500 – $3,200
Underlayment and water barrier	$800 – $1,800
Architectural asphalt shingles (full install)	$3,500 – $7,500
Flashing replacement (chimneys, vents, valleys)	$600 – $1,800
Decking repairs (if needed, per sheet)	$70 – $110 per sheet
Ventilation upgrades (ridge or box vents)	$400 – $1,200

What moves the price up or down? Roof pitch matters. A steep roof on a two-story home takes more time and safety equipment than a low-slope ranch. The shingle brand you choose also shifts cost: CertainTeed and GAF architectural lines are workhorse options, while premium Boral or specialty shingles cost more per square. And if the decking underneath has water damage from years of leaking flashing, replacing that wood adds cost. We show you photos of any damage before we replace a single board.

Every project starts with a free inspection and a written estimate. Call (361) 202-8874 to schedule yours. No pressure, no obligation, just a real number from a real person.

Shingle Brands We Install and Trust

We install and repair roofs with shingles from manufacturers that have proven themselves in Central Texas weather. GAF and CertainTeed architectural lines hold up well to hail and extreme heat, and we regularly recommend them for their balance of durability and price. Boral products work well for homeowners who want a heavier, stone-coated option that stands up to Austin’s intense sun. We’re familiar with the full product lines, but we won’t push a brand that doesn’t match your budget or your roof’s slope. What matters is that the shingle is installed correctly, with the manufacturer’s recommended nailing pattern and ventilation. That’s where longevity actually comes from.

What a Full Replacement Protects Against in Austin Specifically

Austin roofs face a specific set of threats, and a full replacement addresses the whole system, not just the spots you can see from the street.

Hailstorms roll through the Hill Country regularly, and even small hail can bruise shingles and crack the mat underneath. Sun exposure in the Texas heat bakes shingles until the asphalt dries and curls. Sudden hard rains test every seam around flashing, and when flashing fails, water gets under the shingles and into the decking fast. A full replacement with new flashing, new underlayment, and properly ventilated decking gives your home a continuous water-shedding surface that handles all three. That’s why replacing the entire system, rather than layering repairs on top of old materials, is usually the smarter financial move for a roof that’s seen 15 or more Texas summers.

FAQs – Full Roof Replacement

How much does a full roof replacement cost in Austin?

A full roof replacement in Austin typically costs between $9,800 and $18,500 for a standard single-family home. The final number depends on roof size, pitch, shingle brand, and whether the decking underneath needs repairs. Every Mercer Roofing Co Austin project starts with a free inspection and a written estimate, so you’ll know your exact number before any work begins. Call (361) 202-8874 for a quote.

How long does a full roof replacement take in Austin?

Most full roof replacements in Austin take 2 to 5 days once materials are on site. Tear-off typically takes one day, decking inspection and repairs another, and shingle installation one to two days depending on roof complexity. Weather delays happen, especially in spring and fall storm season, but we’ll keep you updated with a clear timeline. For a fast assessment of your project, call us at (361) 202-8874.

Is it cheaper to repair my roof or replace the whole thing?

Repeated repairs usually cost more over five years than one full replacement costs once. A full replacement gives you a new water-shedding system from the decking up, which eliminates the recurring leaks and patch cycles that keep adding up. If your roof is over 18 years old, a full replacement is usually the better financial decision. We’ll show you the numbers honestly, either way, with a free estimate from (361) 202-8874.

Can you identify who’s coming to my door before work starts?

Yes. We send you your technician’s name and photo before they arrive. They come in a clean Mercer uniform and show a photo ID badge at the door. Every technician is background-checked and identity-verified under the Threshold Verified standard. That’s not a perk, it’s the baseline for every visit.

Do you offer financing for full roof replacement in Austin?

Many homeowners spread a full replacement over time through financing options we can discuss on the phone. The best first step is a written estimate so you know the real number, then we can talk through payment approaches that fit your budget. Call (361) 202-8874 and we’ll walk you through it.
