10 Signs You Need a New Roof (Don't Ignore These)

Missing shingles, granules in gutters, sagging, and light in the attic are warning signs you need a new roof. Learn all 10 signs and what to do next.

The 10 Warning Signs

Your roof doesn't fail overnight — it gives you warnings. Here are the 10 signs that mean it's time to get a replacement quote.

Age: The Clearest Indicator

If your asphalt roof is 20+ years old, start planning for replacement even if it looks okay from the ground. Most architectural shingle warranties are for 25–30 years, but that's under ideal conditions. Real-world performance varies, and a proactive replacement on your schedule is far less disruptive than an emergency replacement after a bad storm.

What to Do If You See These Signs

Get a professional inspection. Many roofing companies offer free inspections — take advantage of them. Get 2–3 quotes and ask each contractor to specify exactly what they're seeing and why they're recommending repair vs. replacement.

If you're seeing signs 5 or 6 (sagging deck or daylight in attic), don't delay. These indicate structural issues that worsen rapidly and can become safety hazards. Call a contractor immediately.
