Signs Your Roof Needs a Summer Tune-Up

Here are some signs that your roof might need a little extra attention this summer.

As summer sets in, it’s tempting to focus on backyard barbecues and poolside lounging, but don’t forget that your roof is working hard to protect you from the sun’s harsh rays and those sudden summer storms. A seasonal roof tune-up is essential to catch and address any issues before they turn into costly repairs. Here are some signs that your roof might need a little extra attention this summer.

Curling or Buckling Shingles

Curling or buckling shingles are a common sign that your roof is aging or experiencing heat stress. During summer, high temperatures can cause shingles to dry out and lose their shape, making them less effective at protecting your home.


What to Look For:


  • Shingles that appear wavy or distorted.

  • Edges of shingles curling upward or downward.

  • Buckled shingles that lift in the middle.


Why It Matters:


Curled or buckled shingles can allow water to seep under them, leading to leaks and further damage to your roof structure. This can compromise your roof's ability to protect your home during summer thunderstorms.

Missing or Damaged Shingles

Strong winds and heavy rains common in summer storms can dislodge shingles or cause significant damage. Missing shingles leave your roof vulnerable to water infiltration, while damaged ones might not provide adequate protection.


What to Look For:


  • Shingles missing from various areas of the roof.

  • Cracks, tears, or other visible damage on shingles.


Why It Matters:


Gaps from missing shingles can expose the underlying roofing materials to the elements, leading to leaks and deterioration. Damaged shingles can't effectively shield your home from UV rays or rain, increasing the risk of interior water damage.

Granule Loss

Granules are the rough, sand-like coating on asphalt shingles that protect them from UV rays and add fire resistance. Over time, granules can wear away due to weather exposure, especially in hot, sunny conditions.


What to Look For:


  • Excessive granules in your gutters or at the base of downspouts.

  • Bald spots or shiny areas on shingles where granules are missing.


Why It Matters:


Granule loss reduces the shingles' effectiveness in protecting your roof from the sun’s UV rays and can accelerate the aging of your roof. Without granules, shingles can become brittle and less capable of providing weather resistance.

Sagging Roof Deck

A sagging roof deck can indicate serious structural issues that require immediate attention. Summer’s heat can exacerbate any existing weaknesses in your roof structure, potentially leading to significant damage.


What to Look For:


  • Areas of your roof that appear to be sagging or drooping.

  • Visible dips or uneven areas when viewed from the ground or inside the attic.


Why It Matters:


A sagging roof deck may signal problems with the roof’s support structure or excessive moisture damage. Left unchecked, this can lead to a roof collapse, especially under the weight of heavy summer rains.

Leaks and Water Stains

Leaks and water stains inside your home are clear signs that your roof’s protective barrier has been compromised. Summer storms can cause leaks that may go unnoticed until they’ve caused significant damage.


What to Look For:


  • Water stains on ceilings or walls.

  • Damp spots or mold in the attic or upper floors.


Why It Matters:


Leaks can damage insulation, create structural problems, and lead to mold growth. Identifying and fixing leaks early can prevent extensive and expensive repairs down the line.

Algae or Moss Growth

Warm, humid summer conditions can promote the growth of algae or moss on your roof. While they might seem harmless, these organisms can damage roofing materials over time.


What to Look For:


  • Dark streaks or green patches on shingles.

  • Thick, spongy growths in shaded areas of the roof.


Why It Matters:


Algae and moss can retain moisture, which can weaken roofing materials and shorten their lifespan. They can also cause shingles to lift, increasing the risk of wind damage and leaks.

Damaged Flashing

Flashing is the material used to seal and protect the joints and edges of your roof, such as around chimneys, skylights, and vents. Summer’s heat and storms can take a toll on these critical areas.


What to Look For:


  • Rusty, cracked, or broken flashing.

  • Loose or missing flashing pieces.


Why It Matters:


Damaged flashing can lead to water infiltration at roof joints and penetrations, causing leaks and potential structural damage. Ensuring flashing is intact helps maintain the integrity of your roof.

Why Summer Roof Maintenance Matters


Regular roof maintenance, especially before and during the summer, helps extend the life of your roof and ensures your home remains protected. By addressing minor issues early, you can prevent them from turning into major problems that could result in costly repairs or even roof replacement.


Benefits of a Summer Tune-Up:


  • Prevent Water Damage: Catching and fixing issues before they allow water to penetrate your roof helps protect your home’s interior.

  • Extend Roof Lifespan: Regular maintenance can prolong the life of your roof by mitigating wear and tear.

  • Improve Energy Efficiency: A well-maintained roof can help keep your home cooler, reducing energy costs.

  • Enhance Curb Appeal: Keeping your roof in top shape enhances your home's overall appearance and value.




As you enjoy the warm weather and long days, don’t forget about your roof. Conducting a summer tune-up can help you identify and address potential problems early, ensuring your roof continues to provide the protection your home needs.
