5 Signs It’s Time to Replace Your Roof

Your roof is crucial for protecting your home from the elements. Over time, roofs wear out and need to be replaced. But how do you know when it’s time? Here are five telltale signs that it’s time to replace your roof. Keeping an eye out for these signs will help you maintain a secure and protected home for you and your family.


1. Your Roof’s Age

The age of your roof is a big clue. Most asphalt shingle roofs last 20 to 30 years. If your roof is around this age or older, it’s time to start considering a replacement, even if it is well-maintained. Older roofs are more susceptible to issues that can lead to costly repairs or damage to your home.

If your neighbors with homes built around the same time as yours are getting new roofs, it might be a sign that your roof is nearing the end of its lifespan, too.

How to Check:

2. Visible Damage

Look for apparent damage. This includes cracked, curled, or missing shingles and shingle granules in your gutters. Shingles protect your home; they can’t do their job correctly if damaged. Excessive granule loss is a sign that your shingles are wearing out.

Seeing daylight through the roof boards when you’re in the attic means there are gaps. These holes can let in water, pests, and cold air. If you notice more birds, squirrels, or other animals on your roof or attic, they might get in through damaged areas.

Damage to Look For:

3. Water Damage and Leaks

Water damage inside your home is a clear warning sign. If you experience frequent leaks during rainstorms, your roof’s protective barrier is failing. Leaks can ruin your home’s interior, including walls, ceilings, and insulation. If left unaddressed, this can lead to mold growth, which can be hazardous to your health and costly to remove. Look for water stains, mold, or damp insulation in the attic.

Algae or moss can also grow on your roof, causing damage over time because they hold moisture. This can lead to rotting shingles and wood. Visible rotting, especially in wooden roofs, is a clear sign that a roof replacement is needed to prevent further structural damage.

Signs of Leaks:

4. Sagging

A sagging roof indicates structural problems. It can be caused by water damage, heavy snow, or deteriorating roofing materials. A sagging roof is dangerous and could collapse if not promptly fixed. A noticeable change in the pitch or slope of your roof may indicate settling, requiring inspection and potential replacement.

Visible sagging or drooping of the roof deck from the inside or outside is also a severe structural issue that requires immediate attention. This problem can worsen, leading to more extensive damage and potential collapse.

How to Spot Sagging:

5. Higher Energy Bills

An old or damaged roof can increase your energy bills. If you notice a sudden increase in heating or cooling costs, your roof might be the culprit. Poor insulation and leaks can make your HVAC system work harder to maintain a comfortable temperature.

It might be time to replace your roof if it’s made from materials no longer considered effective, like certain old shingles. Plus, updating your roof to a more energy-efficient option can help increase your home’s value.

Signs of Inefficiency:
