How to Know When It's Time for a Roof Replacement

March 27, 2025

Your roof is your home's first line of defense against the elements, and keeping it in top condition is essential for protecting your investment. Over time, exposure to harsh weather conditions, aging materials, and unexpected damage can compromise its effectiveness. But how do you know when it’s time to replace your roof? At Weatherseal Roofing & Home Improvements, we’ve helped countless homeowners in Shelby Township, Michigan, identify when it’s time for a new roof. Here are the key signs that indicate you may need a roof replacement or major repairs.

1. Age of Your Roof

One of the biggest factors in determining whether your roof needs replacement is its age. Most asphalt shingle roofs have a lifespan of 20 to 25 years, while metal, tile, or slate roofs can last longer. If your roof is nearing or exceeding this age, it’s time to schedule an inspection to assess its condition.


2. Curling, Cracked, or Missing Shingles

Shingles that are cracking, curling at the edges, or missing altogether are a clear sign of wear and tear. This kind of damage can leave your roof vulnerable to water infiltration, leading to leaks and structural damage.


3. Water Leaks & Stains on Ceilings or Walls

Water stains, mold growth, or signs of moisture inside your home indicate that your roof may have leaks. Even small leaks can escalate into major problems if left unaddressed. If you notice water damage inside, a professional inspection is recommended.


4. Granule Loss in Gutters

Asphalt shingles are coated with granules that help protect them from UV rays and the elements. If you notice a buildup of granules in your gutters or downspouts, it may be a sign that your roof is deteriorating and losing its protective layer.


5. Sagging Roof Deck

A sagging roof is a serious issue that suggests structural problems. This could be caused by trapped moisture, rotting wood, or weakening roof decking. If you notice sagging areas, contact a roofing professional immediately.


6. Moss and Algae Growth

Excessive moss and algae growth can cause damage to your shingles by trapping moisture and accelerating deterioration. While some growth is normal, large patches of moss may indicate trapped moisture that could lead to roof decay.


7. Higher Energy Bills

If your heating and cooling costs have suddenly increased, your roof could be a contributing factor. A failing roof may allow heat or cold air to escape, making your HVAC system work harder to maintain a comfortable temperature inside your home.


8. Storm or Hail Damage

Michigan weather can be unpredictable, and strong storms or hail can wreak havoc on your roof. After a severe weather event, check for missing shingles, dents, or exposed areas. Even minor storm damage can worsen over time, leading to costly repairs or the need for a full replacement.
