Your roof protects everything inside your home. But unlike other home components, it often goes unnoticed until problems become severe. Knowing the warning signs can save you thousands in water damage and help you plan for replacement before emergencies strike.

1

Your Roof is 20+ Years Old

Most asphalt shingle roofs last 20-25 years. If your roof is approaching this age, start planning for replacement even if it looks fine from the ground. Aging roofs become increasingly susceptible to leaks and storm damage.

What to do: Have a professional inspection to assess remaining lifespan.

Curling or Buckling Shingles

Shingles that curl at the edges or buckle in the middle are past their prime. This happens due to:

  • Moisture damage
  • Poor ventilation
  • Normal aging
  • Improper installation

Curling shingles can't effectively shed water and are prone to wind damage.

3

Missing Shingles

A few missing shingles after a storm can be repaired. But widespread missing shingles indicate:

  • End of shingle lifespan
  • Poor installation
  • Underlying deck damage

If you can see bare spots from the street, it's time for professional assessment.

Granules in Gutters

Asphalt shingles lose granules as they age. Some granule loss is normal, but excessive amounts indicate:

  • Shingles nearing end of life
  • Accelerated deterioration
  • Reduced UV protection

Check your gutters after rain. If they look like sandboxes, your roof is telling you something.

5

Water Stains on Ceilings or Walls

This is the sign you absolutely cannot ignore. Water stains mean active leaks that can cause:

  • Structural damage to rafters and decking
  • Mold and mildew growth
  • Insulation damage
  • Electrical hazards
URGENT: Even small stains indicate big problems. Water travels far from the entry point. Call a roofer immediately.

Sagging Roof Deck

A sagging roofline indicates serious structural issues:

  • Water-saturated decking
  • Compromised rafters
  • Foundation settling

This requires immediate professional attention. Delay can lead to roof collapse.

7

Daylight Through Roof Boards

Go to your attic on a sunny day. If you see daylight coming through:

  • Shingles are missing or damaged
  • Flashing has failed
  • Decking has gaps or holes

If light gets in, water can too.

8

High Energy Bills

Sudden increases in heating or cooling costs can indicate:

  • Poor roof ventilation
  • Insufficient insulation
  • Air leaks through roof

A new roof with proper ventilation can reduce energy costs by 10-20%.

Repair vs. Replace: How to Decide

Repair If:

  • Roof is under 15 years old
  • Damage is isolated to small area
  • Shingles are available to match
  • Decking is sound
  • Repair cost < 30% of replacement

Replace If:

  • Roof is 20+ years old
  • Damage is widespread
  • Multiple previous repairs
  • Decking is compromised
  • You plan to sell soon
