8 Signs Your Need to Replace Your Roof

Your roof is the guardian of your home, always on duty, shielding it from harsh weather and natural challenges. Like any hard-working protector, it needs a little care now and then. Time, storms, and unforeseen events can take a toll on your roof, nudging it toward retirement. In Pittsburgh, for example, weather conditions mean the average roof lifespan is about 20 years.

That’s why it’s crucial for homeowners, specifically in Pittsburgh, to keep an eye on their roof’s condition. So, let’s explore the signs that indicate it’s time for your roof to hang up its boots and pass the baton to a new one.

1. Age of the Roof

The age of your roof serves as the primary barometer of its health. An asphalt shingle roof, the most common type, typically offers a service life of 20 to 30 years. While you might find the exterior looking fresh as a daisy, internal issues may be brewing under the surface. Regular roof inspections can bring these problems to light. As your roof nears its expected lifespan, begin planning for a replacement. Check your roofing records if you’re unsure about your roof’s age.

2. Presence of Curling Shingles

Curling shingles on your roof are a sign that you should be concerned about. They are a warning sign for potential weather damage and leaks that could worsen with time. There are two types of curling you might spot. One is ‘cupping,’ where the edges of your shingles are lifting. The other is ‘clawing,’ where the shingles remain flat at the edges, but the center bulges out. If you live in Pittsburgh and see either of these issues on your roof, it might be time to consider a Pittsburgh roof replacement. If your shingles are curling, it suggests you could need to replace your roof within the next one to five years. Staying aware of these signs can help ensure your roof stays in top shape, protecting your home for years.

3. Observation of Cracks

Cracks on your shingles can signal a bigger issue. When cracks are in one area, just swap the damaged shingles. But, when cracks show up all over, it could be due to wind damage. In this case, you might need a new roof. Experts can guide you well, so don’t wait to call a roofer. They can inspect your roof and tell you what to do next. It’s always best to act fast and fix any problems early. This way, you save money and avoid headaches down the road. Your roof is important. Keep it in good shape, and it will protect your home for years.

4. Missing Shingles

Missing shingles are another clear sign your roof needs attention. If you only have a few missing, you can often replace them without much trouble. But what happens when you can’t find a color match for your old shingles? As they age, shingles can change color because of the weather. It can make it hard to match new ones with the old ones. Some homeowners aren’t too bothered about this. They just choose a color as close as possible to the old one. But imagine your roof starting to look like a mishmash of colors. At this point, you might decide replacing the whole roof is better.

5. Shingle Granule Loss

Shingle granule loss is something you should seriously look out for. When a roof is between 10 to 15 years old, losing some granules is common and expected. But if you see many granules in your gutters, take this as a clear sign. It’s telling you that your roof might need a replacement soon. It gets even trickier if your shingles are new but losing many granules. It could mean that the installation was not done right. If you find yourself in this situation, getting advice from a professional is the best way to go.

6. Growth of Moss and Algae

One sign that your roof needs attention is the growth of moss and algae. Though it may seem like a simple green touch on your roof, it’s not just a cosmetic issue. Moss and algae can mean your roof has too much moisture and humidity. This dampness can harm your roof over time, leading to more severe problems. If you spot a green coat on your roof, it’s time to call in the experts. Professionals can eliminate the moss and algae without harming the small, grainy parts of your roof, known as granules.

7. Sagging Roof

A sagging roof is a surefire signal that you need a new one immediately. It’s more than just a minor issue; it’s a major red flag. Why? Because it points to serious damage, not just on the surface but deeper into your home’s structure. It suggests that your attic and other house parts might be affected too. Problems like rot and moisture can lead to this sagging. These issues eat away at your home’s core, weakening it bit by bit. It shows that your roof has done its time and needs to step down. So, if you see your roof sagging, don’t wait. Call a roofing expert and plan for a replacement immediately.

8. Gaps in the Attic

Imagine walking into your attic one sunny day. You notice a shaft of light filtering in, or worse, a tiny trickle of water making its way down. Alarm bells should start ringing. It isn’t a magical moment or a mini indoor waterfall. It’s a red flag, a clear sign your roof isn’t doing its job right. These gaps are like open doors, inviting sunlight and rain into your home, causing damage over time. Sometimes, these gaps are small, just tiny holes that a roofer can fix easily. But at other times, these gaps could be the tip of an iceberg, hinting at larger, hidden damage. In such cases, patching holes might not cut it. You may need to think about a complete roof replacement.


In conclusion, replacing your roof isn’t just about maintaining the aesthetics of your home; it’s about preserving its integrity. Awareness of these signs and timely actions can help you avoid bigger issues. As homeowners, while we’re entrusting our homes to stand tall against the test of time, it’s crucial to remember that each part, including our roofs, has a life cycle. Understanding this life cycle helps us keep our homes safe, comfortable, and strong for many years to come.
