7 Signs You Need a New Roof (Before It Costs You Thousands)

Your roof is your home's first line of defense. Here are seven signs it may be time to replace it. For a detailed look at how long different materials last, see our guide to roof lifespan by material.

1. Your Roof Is Over 20 Years Old

Most asphalt shingle roofs last 20–25 years. If yours is older, it's living on borrowed time — even if it looks fine from the street.

2. Shingles Are Curling or Buckling

Curled or buckled shingles are a sign of moisture damage or improper installation. This allows water infiltration that can rot your decking.

3. You're Finding Granules in the Gutters

Asphalt shingles shed granules as they age. If your gutters are full of dark, sand-like debris, your shingles are losing their UV protection.

4. Daylight Through the Roof Boards

If you can see daylight through your attic, so can water and cold air. This is an urgent repair situation.

5. Sagging Roof Deck

A sagging roof deck indicates trapped moisture weakening the supporting structure. This can become a collapse risk.

6. Rising Energy Bills Without Explanation

A failing roof with compromised insulation causes your HVAC system to work harder. If your bills spiked for no obvious reason, your roof may be to blame.

7. Storm Damage

After any major storm, have your roof inspected. Insurance companies typically cover storm damage — but you must file within the claim window.
