Fast, Reliable Roofing Company Across Hornsby Bend
Hornsby Bend sits in unincorporated Travis County, which means roofing here doesn’t follow the same playbook as a job inside Austin city limits. Permits run through the county, driveways stretch long, and septic fields sit close enough to the house to matter when a crew stages tear-off debris. Mercer Roofing Co Austin has been working acreage properties around FM 969 and the Colorado River bottom long enough to know what that changes. We plan for it before quoting, not after. If you’re looking for a Roofing Company that shows up with a plan for county inspections, long material hauls, and outbuildings, call us at (361) 202-8874.

Why Mercer Roofing Co Austin Is Hornsby Bend’s Preferred Roofing Company
Homeowners here tend to ask sharper questions than most. They want to know who’s coming, when, and whether the quote will still hold on invoice day. We answer all three before work starts. Every technician we send is background-checked, identity-verified, and dispatched under the Threshold Verified standard. You get the technician’s name and photo before they arrive, and they badge in with a photo ID at your door. No guessing who’s walking up the driveway.
Grant Whitlock, who leads our team, holds every crew to the same written-price rule: the number you approve is the number you pay. Repairs carry a written guarantee for 365 days, and if the repair fails inside that year, we come back at no charge. That’s the Done Right Promise, and it’s part of every job we write in Hornsby Bend, from a small flashing repair on a ranch house to a full replacement on a newer build.
Styles & brands we work with






Roof Coating in Hornsby Bend
Roof Coating in Hornsby Bend is most often a fit for metal roofs on older manufactured homes, barns, and detached shops, where the metal is sound but the surface has oxidized under years of Texas sun and no longer sheds water cleanly. A properly applied coating restores reflectivity, seals pinhole rust, and can buy several more years before replacement. In this low-lying river climate, coatings also help fight the humidity-driven surface corrosion we see on properties near the Colorado River.
When a Coating Makes Sense
We recommend coating when the roof still has structural integrity but shows surface-level wear: light rust blooms, fading, or seams that have begun to weep during heavy rains. If there’s soft decking under the metal or active leaking at penetrations, coating covers the problem without fixing it. At that point we’ll tell you plainly that replacement is the better spend. Hornsby Bend has enough manufactured and mobile homes that we see this distinction weekly.
What It Costs Here
Roof coating on a typical Hornsby Bend metal roof runs $3.50 to $7.00 per square foot, including surface preparation, seam treatment, and a manufacturer-recognized coating system. On a 1,800-square-foot roof, that’s roughly $6,300 to $12,600. Preparation drives most of the range: a shop roof with light surface rust costs less to prep than one caked in old oxidation near a tree line.
Free Roof Estimate in Hornsby Bend
A Free Roof Estimate in Hornsby Bend has to account for things a drive-by quote misses: where the septic drainfield sits, how long the material haul is from the county road, and whether the county will require a setback sheet before we can even file. That’s why our estimate starts with a walk of the whole lot, not just the roof. We measure the house, the shop, the carport, anything with shingles or metal on it, and we map the ground-level constraints before we put a single number in writing.
What the Estimate Includes
You get a written, line-item price for every scope item: tear-off, decking replacement, underlayment, flashing, shingles or metal, and haul-off. The number is fixed. If we find rot under the shingles on tear-off day, we show you photos, explain what changed, and get your sign-off before any additional work proceeds. No change orders slipped in at the end.
How to Prepare Before We Arrive
If your property has a well, septic tank, or drainfield, flag it for us when you schedule. We’ll pull county records before the visit and walk the setbacks during the estimate. Knowing your acreage and driveway length ahead of time helps us plan equipment access, but you don’t need to have anything measured. We do all of that on-site, and the estimate still costs nothing.

Trusted Brands We Service in Hornsby Bend
Mercer Roofing installs and repairs shingle and metal systems from GAF, CertainTeed, and Tamko, among others, and we keep common flashings, ridge caps, and sealants stocked for quick turnarounds on Hornsby Bend properties. If you’re touching up a mid-2000s CertainTeed roof or matching a GAF architectural shingle on a newer addition, we can usually source exact-match material within a day or two. We don’t push one brand. We match what’s on your roof or recommend a product that fits the exposure on your specific lot, which matters here because sun-facing slopes on open acreage cook far harder than shaded suburban roofs.
Common Roofing Company Problems We See in Hornsby Bend Homes
- County permits mistaken for city permits. Foremen who work mostly in Austin pull City of Austin permits out of habit, waste days at the wrong counter, and delay the whole job. We file Travis County from day one and schedule county inspections on the right calendar.
- Quotes that ignore the outbuildings. Many Hornsby Bend lots have a detached shop, barn, or carport that needs its own drip edge, fascia, and flashing. A roofer who quotes by square without walking the lot leaves that off the estimate, then hits you with a change order. We scope every structure on the property before quoting.
- Septic fields and wells ignored until tear-off day. A dumpster parked on a leach field compacts the soil and ruins drainage, and a tear-off next to a well casing can contaminate it. We mark setbacks before staging equipment and factor them into the plan.
- Attic ventilation that looks fine and isn’t. Homes built before 2000 often lack adequate intake venting, so soffits choke with old paint and attics hit 140°F in August. New decking and shingles still fail early when heat can’t escape. We check intake and exhaust before specifying any roof system.

FAQs About Roofing Company in Hornsby Bend
You need a Travis County permit. Hornsby Bend is unincorporated, so City of Austin code doesn’t apply to most roofing work here. Our team files county permits, carries current wind-load maps and county setback sheets, and schedules final inspections on the county’s calendar. For a standard tear-off and reroof in Hornsby Bend, the county inspection is typically scheduled about a week out, not the 48-hour window you’d see inside Austin. Call (361) 202-8874 if you’re unsure which jurisdiction covers your address, and we’ll verify it before we quote.
Any septic drainfield, leach lines, or well casing on the lot changes where we can stage dumpsters, park material deliveries, and run tear-off fall zones. We measure the setbacks during the estimate and plan around them, so the quote reflects any additional haul distance or hand-carry labor. On a lot with a tight north-side drainfield, for example, equipment may need to enter from the east property line, which can add time but prevents compacting the soil over your leach field. Call (361) 202-8874 and tell us where your septic and well sit; we’ll walk it before we write a number.
In most cases yes, we can bundle a detached workshop, mobile home, and main house under one Travis County permit scope, but the roofing systems differ enough that each gets its own line item. The mobile home may take a coating while the workshop needs a full metal reroof and the house gets architectural shingles. We scope each structure separately, then file them under a single county permit where the county allows it, which keeps inspection scheduling simpler. Call (361) 202-8874 and we’ll tell you exactly how your specific structures shake out.
A new roof alone will not fix an overheated attic. If the soffits are choked with old paint or blocked insulation, new decking and shingles will still cook from below, and you’ll void the shingle warranty early. We check attic intake and exhaust on every Hornsby Bend estimate and, where needed, add or clear soffit venting, install a ridge vent, or specify a ventilated system before we quote the replacement. The fix costs a fraction of another premature roof failure. Call (361) 202-8874 for an attic assessment with your estimate.
Acreage and driveway length determine material haul distance, equipment access, and staging layout. On a narrow driveway off FM 969, the shingle bundles may need to be shuttled in a smaller trailer, which changes labor time. On a larger lot, the tear-off debris still needs a clear path to the dumpster that doesn’t cross your septic field. These are the details most roofers skip and then charge you for later as a change order. We’d rather know before the estimate. Call (361) 202-8874; the walk is free and the number we give you will already include the haul.
