The average cost of a new asphalt shingle roof in San Antonio is $14,000. The cost is approximately $400 to $500 per square. This cost depends on a variety of factors including the size of your home, the roofing materials used, and the installation costs of the roofing contractor. Walton Roofing has been building San Antonio tough roofs since 1961. We stand behind our work and strive to do whatever it takes to gain your trust and complete 100% satisfaction! 

Here is a rough estimate of the breakdown:  

  • 10 square roof: $4,000 to $5,000
  • 15 square roof: $6,000 to $7,500
  • 20 square roof: $8,000 to $10,000
  • 25 square roof: $10,000 to $12,500
  • 30 square roof: $12,000 to $15,000

Roofs are measured in “squares”. A 100-square-foot area is considered 1 square in roofing terms. To simplify,  the amount of material needed to cover 100 square feet of roof area is equal to 1 square of roofing material. So, as an example, if a roof surface area is 2000 square feet, the contractor would figure 20 squares. You can approximate how many squares your home is by dividing the square feet of your roof area by 100.

As mentioned above, many other factors make up the cost of a new asphalt roof. Let’s discuss what those are: 

The Type of Roofing Material

Asphalt shingle is the most common type of roofing material in the San Antonio area, and for a good reason! They are 

  • Affordable
  • Available in a variety of colors and styles
  • Easy installation
  • Minimal upkeep
  • Easy to replace damaged shingles
  • No worry of rust or corrosion

Roof System Materials

Your roofing system is comprised of many components. These include

  • Underlayment
  • Ice and water shield
  • Ventilation system
  • Ridge capping

All of these items must be considered in the final price of asphalt shingles. Contact Walton Roofing for an accurate estimate for your home. 


Labor costs not only include the actual installation of the roofing material but also tearing off the old roof and cleaning up the property once the job is completed. There is a great deal of debris that comes off of your roof and that must go somewhere. The unused material is usually taken to a previously approved dump location.

Size and Complexity of Your Roof

As briefly discussed earlier, your roof’s square footage impacts your new roof’s cost. As do other costs such as materials used, labor, and time needed to complete the job. However, one must consider the facets, hips, valleys, and the roof’s steepness when determining the price. Secondly, the higher the roof, the more dangerous the job. The installers must take appropriate precautions to remain safe.
