When to Replace an Old Roof in San Antonio

Knowing when it’s time to replace your roof instead of continuing repairs is crucial, but can be a tough call for San Antonio homeowners. If you have an aging roof that’s started showing signs of wear, how do you know when roof replacement is truly needed? 

General Lifespans
The typical lifespan for most roof types in South Texas is:

  1. Asphalt Shingles: 15-20 years
  2. Wood Shakes/Shingles: 10-15 years  
  3. Flat Roofs: 10-15 years
  4. Metal Roofs: 40-60+ years
  5. Tile Roofs: 50-100 years

If your roof is nearing or past its average lifespan, have a professional inspection done to assess its actual condition. Just because a roof is old doesn’t mean it needs replacement yet.

Factors to Consider
Some telltale signs that your old roof is ready for replacement include:

1. Visible Damage

Severe curling, cracking, tears, missing shingles, or deterioration.

Persistent leaks after repairs have been attempted.

Sagging roof deck or damaged underlayment.

Extensive growth indicating interior water damage.

Poor insulation and airflow may indicate poor roof performance.

For Historic Homes

Many older homes in San Antonio’s historic districts still have their original tile or metal roofs. Make preservation a priority by:

  1.  Choosing materials that match the original roof
  2.  Consulting historic commissions about roof regulations
  3.  Working carefully around decorative eaves and edges
  4. Photographing details before the demo to replicate later
  5. Retaining and reusing intact vintage tiles if possible
