Why Mercer Roofing Co San Antonio Is Alamo Heights’s Preferred Roofing Company

Alamo Heights homes aren’t like houses in the rest of San Antonio. The 1920s through 1950s cottages and ranch styles off Broadway, along Katherine Court, and near the Witte Museum still carry original wood shake or composition shingles under later clay tile and standing seam additions. That layered history means a roof that looks fine from the curb can be hiding decking rot, mismatched flashing, or valleys that have been quietly failing for years. Our crews know what to look for because we’ve opened up enough Alamo Heights roofs to recognize the patterns.

Every technician who arrives at your Alamo Heights home is background-checked and identity-verified under the Threshold Standard. You’ll get the name and photo of your technician before they arrive, and they’ll badge in with a photo ID at the door. No strangers. No surprises. No wondering who’s walking up your driveway.

Grant Whitlock, who leads our San Antonio operation, holds every job to the 365-Day Done Right Promise: if the work isn’t right within a year, we make it right. That’s a written guarantee on every repair, included with every job. No fine print. No exclusions for the stuff that actually matters.

Our reputation in Alamo Heights is built on showing up when we say we will and putting the price in writing before the first nail goes in. Homeowners here tend to ask harder questions, and we think that’s a good thing. The answer should be specific.

Residential Roofing in Alamo Heights

Residential Roofing in Alamo Heights means working with the housing stock this city actually has, not the cookie-cutter subdivisions you see further north and west. We replace and repair roofs on 1930s cottages near Cambridge Elementary, mid-century ranches along Estes Avenue, and the newer construction that’s filled in around the Alamo Heights pool. A full roof replacement on a typical 1,800-square-foot Alamo Heights home runs $11,000 – $18,000, depending on shingle grade, decking condition, and whether the home has the layered original materials that slow down tear-off.

Repair Photography and Written Findings

Before we recommend a repair or replacement on an Alamo Heights roof, we document what’s actually there. Photos, measurements, and a written summary that shows the valley condition, flashing integrity, and decking health. You see what we see. If you’re home, we’ll walk you through it. If not, the report is emailed before any price is finalized.

Insurance-Ready Documentation

Alamo Heights homeowners dealing with hail damage need more than a handshake. We provide the documentation Texas insurance adjusters expect: dated photos of granule loss, impact marks, and wind creasing, plus a line-item scope of work that matches what the policy covers. This documentation matters later when the claim is being reviewed.

Roof Maintenance in Alamo Heights

Roof Maintenance in Alamo Heights isn’t optional. The mature live oaks that make this city beautiful also shed leaves, twigs, and occasionally limbs onto roof planes and into valleys. Trapped leaf litter holds moisture against shingles and flashing, which accelerates corrosion and feeds the moss and algae that thrive on shaded roof slopes. A standard maintenance visit, including cleaning valleys, tightening flashing, resealing penetrations, and a written condition report, runs $250 – $500. Homes with steep tile roofs or heavy tree coverage may run higher.

Valley and Flashing Service

The valleys on Alamo Heights roofs take more punishment than open-lot roofs in San Antonio. When leaves sit in a valley through a hot humid summer, the metal or shingle weave underneath is sitting in a damp, acidic microclimate. We clean, inspect, and when needed, rebuild valleys with custom metal and ice and water shield. This is the difference between a roof that lasts and one that leaks from the same spot every three years.

Flat Patio Cover Junctions

Many Alamo Heights homes have flat patio covers that tie into the main roof line, and the older valleys funnel water directly onto those junctions. We reinforce these intersections with custom metal transitions, replace the sealant if it’s cracked, and make sure water moves away from the house. This is one of the most common leak points in Alamo Heights specifically, and it’s often overlooked by crews that don’t work here regularly.

Trusted Brands We Service in Alamo Heights

We install and repair roofs using manufacturer-recognized shingle brands that include Owens Corning, IKO, and Atlas. For Alamo Heights homeowners, we stock common colors and profiles locally so a repair doesn’t wait on a distribution center in Dallas. Owens Corning Duration and IKO architectural lines cover most ranch-style homes in the area, and Atlas shingles are a strong choice for the wind and hail conditions we see here. If your roof carries a specific manufacturer warranty, we’ll ensure the repair work is done to that manufacturer’s spec. That matters at claim time.

Common Roofing Company Problems We See in Alamo Heights Homes

• Rotted decking hidden under original wood shake. Homes from the 1920s – 1950s often still have the original wood shake buried under later composition shingles. Water gets trapped between layers, rots the decking, and the problem stays invisible until someone actually opens the roof up.
• Valley corrosion from live oak leaf litter. The mature oaks that define Alamo Heights drop leaves into roof valleys year-round. When those leaves sit through humid springs, they hold moisture against metal and shingles, corroding flashing and rotting the underlayment beneath.
• Wind-load ratings that don’t match Alamo Heights requirements. Some contractors quote a standard San Antonio nailing pattern without checking Alamo Heights wind-load requirements. The wrong pattern can strip an architectural shingle’s 130 mph rating, which becomes a problem when a storm does real damage and the insurance adjuster checks.
• Flat patio cover junctions leaking after every heavy rain. The older valley designs on Alamo Heights homes funnel water directly onto flat patio covers. Without custom metal reinforcement at those junctions, the sealant fails, water backs up, and the same leak reappears season after season.
