Top 10 Warning Signs Your Roof Needs Repair or Replacement

Your roof is essential to your home, providing protection from the elements and ensuring a safe and comfortable living space. However, like any part of your house, it can deteriorate over time and may need repair or replacement. How do you know when it’s time to take action? Here are the top 10 warning signs to watch out for.

Age of the Roof

The first thing to consider is the age of your roof. Most asphalt shingle roofs last between 20 and 30 years. If your roof is approaching this age range or even older, it might be time to start planning for a replacement.

Damaged or Missing Shingles

Inspect your roof for damaged or missing shingles. Damaged shingles can allow water to seep into your home, causing damage to the underlying structure. Missing shingles leave your roof exposed to the elements, making it vulnerable to leaks and further damage.

Curling Shingles

Curling shingles are a sign of wear and tear. When shingles curl, they can no longer adequately protect your home from water damage. If you notice a significant number of curling shingles, it’s time to consider a repair or replacement.

Granule Loss

Check your gutters for excessive granule loss. As shingles age, they lose their protective granules, which can lead to leaks and other issues. If you find a large amount of granules in your gutters, it might be time for a new roof.

Sagging Roof

A sagging roof is a serious issue that requires immediate attention. This could indicate structural problems with the roof decking or underlying support system. If you notice any sagging, immediately call a professional for an assessment.

Leaks and Water Damage

Water damage is a common sign that your roof needs repair or replacement. Look for these signs of water damage:

Interior Water Damage

Inspect your attic and interior ceilings for signs of water damage, such as discoloration, peeling paint, or water stains. This could indicate a leaky roof that needs to be addressed.

Mold and Mildew Growth

Mold and mildew growth in your attic or on your ceilings can be a sign of a leaky roof. Not only can this damage your home, but it can also pose health risks to your family.

Damaged or Rusted Flashing

Flashing is the material used to seal roof joints and prevent water from entering your home. Check for damaged or rusted flashing around chimneys, vents, and other roof penetrations. If you find issues, it’s time for repairs.

Rotting Underlayment

The underlayment is a protective layer beneath your shingles that helps prevent water from penetrating your roof deck. If you notice any signs of rotting or water damage on the underlayment, it may be time to replace your roof.

Damaged or Clogged Gutters

Your gutters play a crucial role in directing water away from your home. If they are damaged or clogged, water can back up and cause damage to your roof and foundation. Regularly inspect and clean your gutters to ensure they are functioning properly. If you notice persistent problems, it might be time to consider a roof repair or replacement.

Cracked or Broken Roof Vents

Roof vents help regulate temperature and moisture levels in your attic. If they are cracked or broken, they can allow water to seep into your home, causing damage. Inspect your roof vents for any signs of damage and replace them if necessary.

Higher Energy Bills

A damaged or aging roof can lead to higher energy bills due to poor insulation and increased heat loss. If you notice a sudden spike in your energy costs, it could be a sign that your roof needs attention.

Persistent Pest Problems

Pests like rodents, insects, and birds can cause damage to your roof and create entry points for water. If you’re experiencing persistent pest issues, it’s worth checking your roof for signs of damage.


Keeping an eye out for these top 10 warning signs can help you catch potential roofing issues before they become major problems. Regular inspections and maintenance can prolong the life of your roof and save you money in the long run. If you notice any of these signs, contact a professional roofer to assess the situation and provide the appropriate repair or replacement solution.
