Age: The age of your roof is one of the most significant factors to consider. Most asphalt shingle roofs have a lifespan of 20-25 years. If your roof is approaching or has surpassed this age, it's time to start thinking about a replacement.

Shingle Damage: Damaged or missing shingles are a clear indication that your roof needs attention. Look for curling, cracking, or granule loss on your shingles. These issues can make your roof vulnerable to leaks.

Leaks: If you notice water stains on your ceiling or walls, it's a clear sign of a roof problem. Address these leaks promptly to prevent further damage to your home's interior.

Sagging or Drooping Roof: A sagging roof is a severe issue that demands immediate action. It could be a sign of structural problems, and you should consult a professional roofer right away.

Moss and Algae Growth: In Myrtle Beach's humid climate, moss and algae can thrive on your roof. While they may not necessarily indicate the need for immediate replacement, they can lead to shingle deterioration over time.

Increased Energy Bills: An old or damaged roof may not provide adequate insulation, causing your energy bills to rise. If you notice a sudden increase in energy costs, it could be due to your roof's poor condition.

Roof Deck Damage: Inspect your attic for signs of daylight coming through the roof boards. If you can see light or notice a spongy or soft feel when walking on the roof, your roof deck may be compromised.
