10 Signs You Need a New Roof

Replacing a roof too early wastes money. Waiting too long costs more in interior damage, repair bills, and insurance complications. Here are the 10 specific signs that your San Antonio roof is at or near end of life — ranked roughly from "call today" down to "plan for it within 2–3 years." Use this as a self-assessment, then get a professional free inspection for the definitive answer.

1. Active leaks in multiple locations

One leak is a repair. Three or more active leaks across different slopes is a roof failure. Multiple simultaneous leak sources mean the underlayment, flashing, and seal strips are all compromised at once — which happens when the whole roof system reaches end of life together. Call a roofer today if this is your situation.

2. Daylight visible through the roof deck

Go into your attic during daylight. If you can see sunlight coming through the deck (not through vents — through the actual deck), that's a hole or deteriorated decking. Usually replacement territory. Rain is following that same light path, producing unseen water damage you may only be noticing as stains on the ceiling below.

3. Sagging roofline

Visible dips or waves when you look at the roof from the street indicate structural problems — typically rotted decking or compromised rafters. This is a structural concern, not just a roof concern. Replacement with decking replacement (sometimes rafter repair) is required. Don't ignore this.

4. Roof is 22+ years old

Standard architectural asphalt shingle reaches end of life at 22–28 years in San Antonio. If your roof is within that range, an inspection isn't just a good idea — it's the start of your replacement planning. Class 4 impact-resistant lasts slightly longer (28–32 years). Tile and metal much longer. Check original install date from your closing documents or attic stamp.

5. Granules accumulating in gutters

Normal wear produces minimal granule loss. Significant accumulation in gutters and downspouts (more than a handful over a month) signals the shingle has reached end of life. Once the granule layer thins, UV degrades the asphalt beneath quickly — the roof may last 2–5 more years but is on borrowed time.

6. Widespread curling or cupping

Look at your shingles from the ground. Edges curling up, tabs cupping into the shape of a spoon — these indicate shingle end of life. Curling begins at the roof's hottest slopes (south-facing) and spreads. When curling is visible across multiple slopes, the roof is aged out. Replacement within 1–3 years depending on severity.

7. Cracked or missing shingles across multiple slopes

Isolated missing shingles on one slope are typically wind damage — repairable. Missing or cracked shingles across multiple slopes indicate systemic failure. The seal strips are no longer holding, shingles are brittle, and every storm produces more damage. Typically replacement.

8. Rising cooling bills

If your summer cooling bills are rising year-over-year at similar temperatures, the roof may be part of the story. Aged shingles with thinned granule layers absorb more heat and transmit it to the attic. Combined with inadequate ventilation, this drives cooling costs. Not a replacement trigger on its own, but a secondary signal alongside age and visible wear.

9. Multiple post-storm repair claims in recent years

If your roof has had 2–3 insurance claims in the past 10 years, it's been replaced recently — should be fine. But if you've been doing 3–5 small repairs per year outside of insurance (pipe boots, flashing, wind damage, leaks), the pattern indicates the roof is fighting end of life. Repair costs are compounding and replacement becomes economically rational.

10. Insurance carrier flagging renewal

Some insurers now require roof condition reports at renewal for homes 20+ years old and decline renewal or raise rates significantly for roofs they consider near end of life. If your renewal has flagged the roof, it's a strong signal. Replacing proactively can preserve your insurability and keep premiums manageable.
