10 Warning Signs You Need a New Roof

Your roof works hard every single day, quietly protecting your home from sun, rain, wind, and snow. But no roof lasts forever, and knowing when to replace yours can save you thousands of dollars in water damage, mold, and structural repairs.

Here are the ten warning signs that your roof may be due for a replacement rather than another patch job.

1. Your Roof Is Simply Old

Most asphalt shingle roofs last 20–30 years. If yours is approaching or past that age, even if it looks okay from the ground, it's worth a professional inspection. Materials degrade with time, and an aging roof can fail quickly after a single storm.

2. Curling, Cracking, or Buckling Shingles

Shingles that curl at the edges, crack, or buckle have lost their protective granules and flexibility. When you see this across large sections of the roof, it's usually a sign the whole system is nearing the end of its life.

3. Granules in the Gutters

Finding sand-like granules in your gutters and downspouts means your shingles are shedding their protective coating. A few after installation is normal; ongoing heavy granule loss is not.

4. Daylight or Leaks in the Attic

If you can see daylight through the roof boards in your attic, or notice water stains, damp insulation, or a musty smell, water is getting in. This is one of the most urgent signs to act on.

5. Sagging Rooflines, Missing Shingles, and More

A sagging roof deck points to trapped moisture or structural issues and should be inspected immediately. Other red flags include widespread missing shingles, damaged flashing around chimneys and vents, moss or rot, and rising energy bills from poor attic ventilation.

• Sagging or uneven rooflines
• Multiple missing or torn shingles
• Damaged or rusted flashing
• Moss, algae, or visible rot
• Climbing heating and cooling bills
