In Austin, most residential roofs are asphalt shingles rated for 25–30 years. In Texas heat, that often means 18–22 years of actual useful life. Here's how to tell when it's time to replace versus repair.
Sign 1: Your Roof Is 18–20+ Years Old
Age is the most reliable indicator. If your asphalt shingle roof is approaching 20 years in Austin's climate, plan for replacement in the next 2–3 years regardless of visible condition. The granules are depleting, the shingles are becoming brittle, and a major storm event will expose the underlying condition.
Sign 2: Widespread Granule Loss
Asphalt shingles protect themselves with ceramic granules embedded in the surface. As roofs age, those granules shed into gutters and onto the ground below downspouts. Heavy granule loss means the shingles are UV-degrading and their useful life is ending.
Sign 3: Multiple Leaks or Repeat Repairs
One roof leak in 10 years: repair it. Three or more leaks, or a repair that came back: the roof is failing broadly, not just at isolated points. Repeated repairs are expensive and temporary — you're paying to delay the inevitable.
Sign 4: Visible Shingle Damage from the Ground
If you can see cracked, curled, or missing shingles from the ground, the damage is significant. Curling shingles indicate heat damage and age. Missing shingles mean the wind resistance is compromised and water is getting in.
Sign 5: Hail Damage
After a significant hail event in Austin, check your roof. Quarter-sized hail or larger causes functional damage to asphalt shingles — bruising that removes granules and accelerates aging. This damage is often covered by homeowners insurance. We document it and manage the claim.
Sign 6: Dark Streaking on Shingles
Black streaking is typically algae growth. This is cosmetic but indicates moisture retention that accelerates shingle degradation. Cleaning helps temporarily. On an older roof, it's usually worth addressing when replacing.
Sign 7: Your Neighbors Are All Getting New Roofs
If your neighborhood was built in a single phase and multiple neighbors are replacing roofs, yours is likely the same age and in the same condition. Don't wait for a major leak to confirm what the calendar is already telling you.
The Repair vs. Replace Math
A typical Austin roof repair runs $500–$2,500. A full replacement runs $12,000–$35,000 depending on roof size and material. If you're doing $1,500+ in repairs every couple of years on a 20-year-old roof, you're subsidizing a replacement without getting a new roof. Replace it, get the warranty, and stop writing service call checks.
