Fast, Reliable Roofing Company Across Castle Hills
Roofing work in Castle Hills runs roughly $450 – $680 per square for a full tear-off and architectural shingle replacement, while roof coating on a low-slope section typically lands between $3.50 and $6.00 per square foot. Those are real numbers for this city’s market, not a generic San Antonio bid. Castle Hills sits almost fully surrounded by San Antonio, but it runs its own city government and its own permitting office, which means the work has to meet Castle Hills’ specific inspection standards, not the neighbor’s. Our crews know the difference. We work on mid-century ranches off Honeysuckle Lane, custom builds from the 1970s and 1980s, and everything in between. If you need a straight answer about what your roof needs and what it’ll cost, call (254) 276-4369.
Why Mercer Roofing Co San Antonio Is Castle Hills’s Preferred Roofing Company
Homeowners in Castle Hills tell us the same thing over and over: they want to know who’s walking up the driveway before the doorbell rings. That’s the problem we built our process around. Before any technician arrives, you get their name and photo sent to you. When they show up, they’re in a clean, marked uniform and they present a photo ID badge at the door. Every technician is background-checked and identity-verified under the Threshold Verified standard. No mystery subcontractors, no “some guy will be in the area.” That matters in a small city like Castle Hills, where people actually know their neighbors and notice unfamiliar trucks.
We also answer the phone with a live person, 24 hours a day. Not a voicemail tree, not a call-back form. A human picks up. For Castle Hills homeowners who’ve had a storm blow through at night or found water staining a ceiling on a Saturday morning, that’s the difference between an answer and anxiety.
Grant Whitlock leads our team, and he’s built our reputation in Castle Hills on one simple rule: a written price before any work starts, every time. No exceptions. That’s not conditional, it’s not optional, it’s how we quote. If you call us for a roof inspection or a replacement estimate in Castle Hills, you’ll see the full price on paper before a nail is driven.
Our Roofing Company team also carries the 365-Day Done Right Promise. If the work isn’t right within a year, we make it right. And every repair includes a written guarantee. If a repair fails, the second visit is free. We put that in writing because Castle Hills homeowners deserve to hold us to it.

Roof Coating in Castle Hills
Roof coating in Castle Hills is a practical solution for the low-slope and flat sections found on many 1960s and 1970s builds across the city, and it typically runs $3.50 – $6.00 per square foot depending on surface condition and coating type. Those older Castle Hills homes often have a main pitched roof with a low-slope back section or a patio cover that collects standing water after a South Texas downpour. A properly applied elastomeric or silicone coating seals hairline cracks, reflects UV, and can extend the life of that section by 10 to 15 years without a full tear-off.
When Coating Makes Sense
If your Castle Hills home has a built-up roof or modified bitumen section that’s still structurally sound but showing age, coating is often the most cost-effective move. We inspect the decking and seams first. If the surface is too far gone, we’ll tell you straight and price a replacement instead. We don’t coat over rot and call it done.
Reflectivity and Castle Hills Heat
Castle Hills summers push surface temperatures past 150°F on a dark roof. A white or light-gray coating reflects a significant portion of that heat, which can lower cooling costs inside the home and reduce thermal stress on the roofing material itself. For older ranch-style homes with limited attic insulation, the difference is noticeable within the first summer.
Free Roof Estimate in Castle Hills
A free roof estimate in Castle Hills is exactly what it sounds like: we come out, walk the roof, document what we find with photos, and hand you a written line-item quote before we leave. There’s no charge for the visit and no pressure to sign anything. For Castle Hills specifically, that estimate includes checking the roof’s low-slope sections, the current condition of flashing around penetrations, and the nailing pattern if you’re considering a re-roof. We know what the city’s inspectors look for, and we build that into the quote from the start.
What the Written Estimate Includes
Your estimate lists material brand and model, tear-off and disposal labor, underlayment type, flashing work, ventilation, and any decking replacement we anticipate. It also notes the permit fee through Castle Hills’ own city office. Nothing gets left as a verbal promise. If the scope changes mid-job, you get a written change order before we proceed, never a surprise line item on the final invoice.
Why We Document Everything
For Castle Hills homeowners, a documented estimate and final inspection record matters beyond the job itself. When you file an insurance claim for hail damage or wind uplift, the adjuster wants to see that the work was permitted in the correct jurisdiction and passed the city’s final inspection. We give you the paper trail. That’s part of the no-hassle approach we’ve built our reputation on in Castle Hills.
Trusted Brands We Service in Castle Hills
We install and repair shingle systems from GAF, CertainTeed, and Owens Corning, and we stock common accessories and flashing materials for quick turnaround on Castle Hills jobs. For a re-roof that has to pass Castle Hills’ wind-load inspection, CertainTeed Landmark architectural shingles with a six-nail starter strip pattern is a workhorse we specify often. GAF’s Timberline line carries strong wind ratings that satisfy Castle Hills’ uplift requirements when installed to the printed specs. We’re familiar with what each manufacturer requires for warranty coverage, and we document the installation accordingly.
Common Roofing Company Problems We See in Castle Hills Homes
- Wrong-jurisdiction permits. A roofer habitually pulls a permit through the City of San Antonio because that’s where most of their work is. Castle Hills requires its own permit, and a San Antonio permit won’t pass the final inspection here. We’ve seen re-roofs held up for weeks over this.
- Failed nailing-pattern inspections. Castle Hills inspectors specifically look for six-nail high-wind patterns on architectural shingle re-roofs. A standard four-nail job, even if it looks fine, can fail the re-roof inspection. We’ve fixed more than one roof where this was the root cause.
- Shingles on low-slope sections. Homes built in the 1960s through 1980s in Castle Hills frequently have a 2:12 or lower pitch on the back section. Shingling that pitch voids the wind rating and leads to a failed roof-off inspection. That section needs torch-down, modified bitumen, or a coating system instead.
- Old penetrations leaking quietly. Original composition shingles on mid-century Castle Hills ranches are now decades past their useful life. We regularly find pipe jacks and stack flashings that have been leaking around the penetration for years, slowly rotting the decking beneath. By the time you see a ceiling stain, the damage is often well underway.

FAQs About Roofing Company in Castle Hills
Yes, Castle Hills operates its own city government and pulls roofing permits through its own office, not through San Antonio’s. A permit issued by San Antonio for a home inside Castle Hills boundaries will not pass final inspection. We handle the Castle Hills permit on every project and build the fee into your written estimate. Call (254) 276-4369 for a quote that’s actually valid in your jurisdiction.
Castle Hills inspectors look for a six-nail high-wind nailing pattern on architectural shingle re-roofs, which is a stronger fastening schedule than the standard four-nail pattern used elsewhere. We specify CertainTeed Landmark or GAF Timberline with the six-nail starter strip pattern to meet the city’s wind-load requirements. If you want to know whether your existing roof would pass, call (254) 276-4369 and we’ll check it.
No, not if the pitch is 2:12 or lower. Shingles on a low-slope section void the manufacturer’s wind rating and will fail a Castle Hills roof-off inspection. Those sections need torch-down, modified bitumen, or a roof coating system instead. We inspect the slope on every Castle Hills estimate and quote the correct material for each section. Call (254) 276-4369 to set up a free estimate.
A documented Castle Hills permit with a passed final inspection proves that your roof met the city’s wind-load requirements at the time of installation. When you file a hail or wind claim, that documentation supports the replacement cost and can help with the adjuster’s review. On a mid-century ranch off Honeysuckle Lane, our crew re-roofed with CertainTeed Landmark and a six-nail pattern, and the city’s final sign-off on the nailing schedule gave the homeowner the paper trail their insurance file needed. Call (254) 276-4369 to get that same documentation on your Castle Hills roof.
A compliant quote includes the Castle Hills permit fee, the six-nail high-wind nailing pattern on architectural shingles, correct material on low-slope sections, ice and water shield at the eaves, and documentation for every step. A cheap bid often leaves out the permit entirely, quotes a four-nail pattern, and slaps shingles on a 2:12 pitch. That bid will fail inspection and cost more to fix than doing it right the first time. Call (254) 276-4369 and we’ll show you the difference in writing.
