When to Replace Your Roof: 9 Clear Signs It’s Time for an Upgrade

Your roof is your home's first line of defense — shielding you from rain, sun, wind, and everything in between. But how do you know when it’s time to stop repairing and start replacing? Ignoring the warning signs can lead to more serious problems like water damage, mold, and structural deterioration. In this guide, we’ll walk you through nine clear signs it’s time for a roof replacement, and what steps to take next.

1. Your Roof is 20+ Years Old

Asphalt shingle roofs typically last around 20 to 25 years. If your roof is approaching or past this age — especially if it was installed over an older layer of shingles — it’s likely time to start planning for replacement.

🡒 Check out our Roof Replacement page to learn more about the process.

2. Shingles are Curling, Buckling, or Missing

Curling at the edges (cupping) or raised centers (clawing) means your shingles have aged and are no longer sealing properly. Missing shingles leave your home vulnerable to leaks and further damage, especially during storms.

🡒 We offer expert Residential Roofing services across North Texas.

3. Granules in Gutters

If your gutters or downspouts are filling with shingle granules, your roof's protective layer is deteriorating. This usually happens toward the end of a shingle’s life and accelerates UV and water damage.

4. Water Damage in Your Attic or Ceilings

Check for brown stains on ceilings, bubbling paint, or visible leaks in your attic. These signs often point to roof failure and demand urgent attention to prevent mold and rot.

5. Sagging Roofline

A sagging roofline could indicate trapped moisture, rot, or structural problems in your decking or supports. This isn’t a cosmetic issue — it’s a structural red flag.

🡒 Schedule a Roof Inspection to get clarity on your roof’s integrity.

6. Moss, Algae, or Mold Growth

Moss retains moisture against your shingles, which can deteriorate them over time. While moss or algae alone isn’t an emergency, extensive growth indicates it’s time to assess the health of your roof.

7. Damaged Flashing or Valleys

Flashing around chimneys, skylights, and roof valleys is critical for preventing water intrusion. Cracked or rusted flashing is often a precursor to major leaks.

🡒 We use Owens Corning Roofing products for durability and performance in every install.

8. Light Coming Through the Roof Boards

Head into your attic during the day — if you see sunlight peeking through the boards, water has a path in too. This is a clear sign the underlayment and possibly decking need replacing.

9. Your Neighbors Are Getting New Roofs

If multiple homes in your neighborhood are replacing their roofs — especially if they were built around the same time — your roof may be next. Builders often use similar materials, so their lifespan tends to align.
