Fast, Reliable Roof Installation Across Castle Hills
A full roof installation in Castle Hills typically runs $9,800 to $18,500 for a standard ranch-style home, with standing seam metal starting around $16,000 and tile roofs running $22,000 to $38,000 depending on square footage and decking condition. We schedule Castle Hills installations within 5 to 10 business days of the signed contract, and the permit process adds roughly 48 hours because Castle Hills runs its own building department separate from San Antonio. Call (254) 276-4369 and we’ll walk the property, measure the roof, and hand you a written price before any work begins.
Castle Hills is not just another San Antonio suburb. It is an incorporated city with its own permit office, its own inspection schedule, and its own rules about what happens between tear-off and final shingle. We know the process cold, and we build our installation timeline around it so you are not waiting on a failed inspection or an open roof during a July thunderstorm.
Why Mercer Roofing Co San Antonio Is Castle Hills’s Preferred Roof Installation Company
Castle Hills homeowners call us because we do not make them guess who is showing up. Every technician we dispatch is background-checked, identity-verified, and arrives in a marked uniform with a photo ID badge at the door. We send the technician’s name and photo to you before the visit. If the person standing on your porch does not match the photo, do not open the door.
The roofs in Castle Hills are older than most of what you will find in surrounding San Antonio neighborhoods. The housing stock here leans heavily toward mid-century ranch builds and custom homes from the 1960s through the 1980s. That means composition shingle roofs reaching replacement age, low-slope sections with failing built-up roofing, and decking that has quietly rotted under layers of trapped moisture. Our crews have opened enough Castle Hills roofs off Lemonwood Drive, West Avenue, and Jackson-Keller Road to know what is under them before we tear off the first square.
Every installation we complete in Castle Hills includes a written guarantee, and every price is set in writing before we start. No change orders appear out of nowhere. If an inspection reveals decking rot or code-upgrade requirements, we price the fix and get your signed approval before we touch it. That is how we have earned our reputation in Castle Hills, and why homeowners keep our number saved.

Standing Seam Metal Roof in Castle Hills
Standing seam metal roof installation in Castle Hills is a common upgrade for homeowners who want to stop replacing shingles every 15 years and start owning a roof that handles hail and 105-degree heat without granule loss. A standing seam metal roof on a typical Castle Hills ranch home runs $16,000 to $28,000, depending on roof complexity, decking replacement, and whether the home has low-slope sections that require specialized underlayment. The panels lock together vertically with concealed fasteners, which means no exposed screws and far fewer leak points than corrugated metal.
How Heat and Hail Change the Calculation
South Texas heat breaks down asphalt shingle granules fast. Castle Hills homes that face full western exposure off streets like Lemonwood Drive or Honeysuckle Lane lose granules noticeably faster than shaded lots. Impact-resistant standing seam panels shrug off the dime-to-quarter-size hail that sweeps through Bexar County in spring, and they carry Class 4 impact ratings that can lower homeowners insurance premiums.
What the Castle Hills Inspector Checks
When you switch from composition shingles to standing seam metal in Castle Hills, the permit triggers updated nailing patterns and drip-edge profiles. Out-of-town roofers who mostly work in San Antonio sometimes miss these details and fail the final inspection. Our crews install to Castle Hills’ current code the first time, because we know the inspector is going to look at the underlayment, the panel seams, and the flashing before signing off.
Tile Roof in Castle Hills
Tile roof installation in Castle Hills suits the larger custom homes built in the 1970s and 1980s, particularly those with Spanish or Mediterranean architectural lines along streets like Lockhill Selma and broad lots off West Avenue. A tile roof on a Castle Hills custom home runs $22,000 to $38,000 on average, with concrete tile at the lower end and clay or Boral tile at the higher end. Tile handles Texas heat beautifully and can last 50 years, but the structure underneath must be sound enough to carry the weight.
Decking and Structure Come First
Castle Hills homes built before 1980 often have 3/8-inch plywood decking that was never meant to support tile. Before we quote a tile installation, we inspect the attic and, when possible, lift a section of the existing roof to check what is underneath. If the decking needs to go, that line item goes in the written estimate before you sign, not after.
Flashing Around Original Brick and Clay Vents
Many Castle Hills custom homes still have their original brick chimneys and clay-tile vent stacks. Tile installation around these penetrations requires custom flashing work. We fabricate and install the flashing on site, and the mid-install Castle Hills inspection gives the city a chance to verify that work before we lock tiles in over it.
Trusted Brands We Service in Castle Hills
We install and repair GAF, CertainTeed, and Owens Corning shingle systems, plus Boral tile and standing seam metal panels from manufacturers recognized for Texas performance. Because we stock common Castle Hills roof profiles locally, we can order and stage materials without the week-long waits that plague out-of-area crews. When you choose a GAF Timberline or CertainTeed Landmark system, you get the full manufacturer warranty, and our 365-Day Done Right Promise covers the workmanship: if something is not right within a year, we make it right at no charge.
Common Roof Installation Problems We See in Castle Hills Homes
- Failed built-up roofing on low-slope sections. Many Castle Hills ranch homes have a flat or low-slope section over a carport, patio, or addition. The original torch-down or built-up membrane cracks after decades of heat, and water finds the plywood underneath.
- Delaminated 3/8-inch decking. On a mid-century ranch off Lemonwood Drive, our crew opened up a failing built-up roof to find the original 1962 decking was 3/8-inch plywood that had delaminated under years of trapped moisture. We replaced 740 square feet of decking, added GAF StormGuard ice-and-water shield over the low-slope section, and re-flashed all three penetrations before the Castle Hills inspector arrived for the mandatory pre-shingle check.
- Roof-to-wall flashing failures at brick chimneys. Mid-century ranch homes are most vulnerable where roof meets original brick chimney or clay-tile vent. When the old flashing corrodes or pulls away, water follows the wall line into the house.
- Missed permit-triggered code upgrades. Switching material types in Castle Hills often triggers updated requirements for drip edge, nailing patterns, or underlayment. Roofers who do not know Castle Hills permits fail final inspection and leave the homeowner holding an open permit.

FAQs About Roof Installation in Castle Hills
Yes. Castle Hills operates its own building department and permit office, entirely separate from San Antonio. Any roof installation within Castle Hills city limits requires a Castle Hills permit, and the city runs its own inspection schedule. We pull the permit for you and coordinate every inspection as part of the installation.
For low-slope sections, the right material is usually modified bitumen or torch-down membrane over new decking, sometimes paired with GAF StormGuard or a similar ice-and-water shield. The key is replacing any 3/8-inch plywood decking that has flexed or delaminated underneath. We will assess the slope, check the decking, and give you a written price for the membrane system that will actually last. Call (254) 276-4369 to schedule the inspection.
Yes. Castle Hills requires a mid-install inspection after underlayment goes down and before shingles or panels are applied. The inspector looks at underlayment coverage, fastener patterns, drip edge, and flashing at penetrations. We schedule that inspection into the timeline, and we do not cover the underlayment until the inspector signs off. It is a stricter sequence than what surrounding areas require, and it protects you.
Most Castle Hills mid-century ranch homes run between 22 and 32 squares, with larger custom builds off Lockhill Selma and West Avenue running 35 to 45 squares. One square is 100 square feet. We measure the actual roof surface, not the home’s footprint, so the price reflects real material and labor.
In most cases, yes. Standing seam metal is lighter per square than tile and often lighter than old built-up roofing. The structure usually does not need reinforcement, but the permit may still trigger updated nailing patterns and drip-edge requirements. We will confirm the structural load during the estimate and include any necessary changes in the written price. Call (254) 276-4369 and we will take a look before you commit to anything.
