Is It Time to Replace Your Asphalt Shingles? 7 Signs You Shouldn’t Ignore

A roof in good condition does more than keep out the rain. It protects your home from moisture damage, improves energy efficiency, and adds curb appeal. While services like house washing and roof cleaning help maintain appearance, they can't reverse the wear and tear that builds up over time. If your roof is covered in aging asphalt shingles, you may already be seeing the warning signs of failure. Understanding what to look for can help you make a smart decision before damage spreads indoors.

1. Curling or Buckling Shingles

When asphalt shingles begin curling at the edges or buckling upward, it signals they’ve lost their grip and strength. These shingles can’t shed water properly and are more likely to tear away in high winds. This type of damage affects your roof’s ability to protect your home and should never be ignored.

2. Missing Shingles After Storms

Even a few missing shingles can cause serious problems. Gaps in your roof leave the underlayment and wood decking exposed to moisture, which can lead to leaks and rot. If storms frequently blow shingles off your roof, it may be time to speak with a roofing contractor about a full replacement rather than temporary patchwork.

3. Granule Loss and Bald Spots

The granules on asphalt shingles serve as a protective layer that shields them from sunlight and harsh weather. If you notice granules collecting in your gutters or see shiny, bald patches on your roof, it means your shingles are breaking down. Granule loss reduces durability and shortens the life of your roof.

4. Sagging Roofline

A sagging roofline often means there’s serious damage beneath the surface. It could be caused by water intrusion, rotting structural components, or a roof that was poorly installed. While asphalt shingles may appear intact, the underlying structure could be compromised. This is an issue that requires immediate attention from roofing specialists who can assess the full extent of the problem.

5. Dark Streaks and Algae Growth

Those black streaks you see on your roof are usually caused by algae. This type of growth not only looks bad but also traps moisture against your shingles, which speeds up deterioration. Although roof cleaning can help temporarily, repeated algae buildup may mean your shingles are no longer able to resist moisture and need to be replaced.

6. Increased Energy Bills

If your utility bills are rising and you haven’t made any major changes to your heating or cooling systems, your roof might be the reason. Old or damaged asphalt shingles allow more heat to escape in the winter and enter in the summer, making your HVAC system work harder. Roofing specialists can evaluate whether a replacement will help improve your home's energy performance.

7. Age of the Roof

Asphalt shingles typically last between 15 and 25 years, depending on the product and the quality of the installation. If your roof is within or past that timeframe, it’s time to plan for replacement even if no damage is visible yet. Aging shingles lose flexibility, sealing power, and weather resistance, making them more vulnerable during storms.

Here are a few signs that should prompt you to call in a roofing contractor right away:

• Water stains on ceilings or walls
• Loose or sagging gutters pulling away from the house
• Daylight visible in your attic through roof boards
• Shingles shedding granules even without heavy rain
• Soft or spongy spots when walking on the roof (only to be checked by a professional)

These symptoms often suggest that damage has reached beyond the surface of your asphalt shingles. Acting quickly could prevent extensive repairs and help you protect your investment.
