Short answer: If your asphalt shingle roof is around 20 years old in Austin, replacement is usually the better long-term choice, especially if the shingles are brittle, losing granules, or have needed several repairs. A repair can still make sense when the damage is isolated and the rest of the roof is sound. A free inspection will tell you which situation you are in.
Why 20 Years Is the Turning Point in Central Texas
Austin summers are hard on asphalt shingles. Long stretches of triple-digit heat and strong UV exposure dry out the asphalt, and spring hail and wind add wear on top of that. Many standard shingle roofs in Central Texas reach the end of their reliable life somewhere around the 15 to 20 year mark, even if they were rated for longer.
That does not mean every 20-year-old roof needs to come off. It means the roof deserves a close look before you put money into another repair.
When a Repair Still Makes Sense
- The damage is in one area: a few missing shingles after a wind storm, one leaking pipe boot, or a single flashing problem.
- The shingles are still flexible: they lie flat, are not curling or cracking, and still have most of their granules.
- The decking is solid: no soft spots, sagging, or widespread water staining in the attic.
- You plan to sell soon: a well-documented repair can be a reasonable bridge if you will not be in the home much longer.
When Replacement Is the Better Investment
- Shingles are curling, cracking, or brittle across multiple slopes.
- Heavy granule loss: bare spots on shingles or lots of granules in the gutters.
- Repeated leaks or more than one repair in the last few years.
- Hail or wind damage on several slopes, not just one spot.
- Matching problems: on older roofs, the original shingle may no longer be made, so repairs can look patchy.
- Rising insurance costs: some carriers look closely at roof age. An updated roof may qualify you for better terms, so check with your agent.
Repair vs. Replacement: What It Costs You Over Time
A repair is cheaper today, but on an aging roof each repair buys less time. If you are likely to need a full replacement within a few years anyway, money spent on repairs now does not carry forward. Replacement also lets you upgrade, for example to Class 3 and Class 4 impact-resistant shingles that stand up better to Central Texas hail. See our roof replacement page for materials and timelines, and our Austin roof replacement cost guide for pricing factors.
What a Good Inspection Should Tell You
At Prosperity Roofing & Exteriors, every inspection is free and drone-assisted, and everything we find is documented with photos in CompanyCam.

If we recommend a repair, it comes with a 1-year warranty. If replacement makes more sense, materials are covered by the manufacturer warranty, and our workmanship warranty is 7 years, extended to 10 years with Platinum Protection.

FAQs
How long does an asphalt shingle roof last in Austin?
Many standard asphalt shingle roofs in Central Texas last roughly 15 to 20 years because of the intense heat, UV exposure, and storm season. Higher-quality and impact-resistant shingles, good attic ventilation, and regular maintenance can help a roof last longer.
Is it worth repairing a 20-year-old roof?
It can be, if the damage is isolated and the rest of the roof is in good condition. If the shingles are brittle, losing granules, or have needed repeated repairs, replacement is usually the better value.
Will my insurance pay to replace an old roof?
Insurance generally covers sudden damage, such as hail or wind, not normal aging. If there is storm damage, we can document it with photos and meet your adjuster on site. Coverage decisions are made by your insurance carrier.
