Your roof is important, as it’s the first line of defense. Yet, despite it’s importance, it’s easy to forget about it until there’s a leak or visible damage. While routine maintenance helps extend its lifespan, every roof eventually reaches the point where repairs just aren’t enough. So how do you know if it’s time for a roof replacement? At RGB Construction, we’ve inspected thousands of roofs across South Jersey and know what signs to look for. Here are 6 clear signs that it is time to replace your roof:
Key Takeaways
- ✔ If your roof is 20+ years old, it may be time to replace it—even if it looks okay from the ground.
- ✔ Curling, cracked, or missing shingles leave your roof vulnerable to leaks and water damage.
- ✔ Granule buildup in your gutters means your shingles are losing their protective coating.
- ✔ Sagging rooflines or soft spots indicate structural problems that often require full replacement.
- ✔ Persistent leaks and water stains are a sign of roofing system failure—not just surface damage.
- ✔ Frequent repairs are often more expensive long-term than investing in a full roof replacement.
1. Your Roof is 20+ Years Old
Most asphalt shingle roofs are designed to last 20 to 30 years under ideal conditions. But in New Jersey, we see our fair share of heavy winds, snow, humidity, and extreme heat. All of those things can shorten that lifespan. Even if your roof appears fine from the ground, time takes its toll. Flashing may weaken, shingles may dry out and crack, and underlayment can deteriorate without any obvious signs.
If it’s been more than two decades since your last roof replacement—or if you just don’t know how old your roof is—it’s a good idea to schedule a professional inspection. Catching issues early could help you plan for replacement before leaks or structural damage occur.
2. Shingles are Missing, Curling, or Cracking
Shingles are your roof’s outer armor, and when they start to show wear, your roof’s overall protection is compromised. Curling at the edges, blistering, cracking, or whole shingles coming off in high winds are all signs your roof is breaking down. These issues often appear after storms or years of sun exposure, especially on older roofs.
Missing or damaged shingles allow water to seep underneath, putting your roof decking, insulation, and even drywall at risk. You might spot shingle fragments in your yard or notice dark patches where shingles are missing. While isolated damage can sometimes be repaired, widespread deterioration typically means it’s time for a replacement.
💡 Pro Tip
If you live in Cherry Hill or anywhere in South Jersey and notice small roof issues after a storm, don’t wait. A professional roof inspection from RGB Construction can help you decide whether you need a repair or replacement—before hidden water damage drives up the cost.
3. Granules in the Gutters
If you have asphalt shingles, here’s one thing you need to look out for: granule loss. Shingles are coated with small mineral granules that protect them from the sun’s UV rays and improve fire resistance. Over time, granules can loosen and wash away. During storms, they may get scraped off by fallen debris. When this happens, the shingles become brittle and less effective at repelling water.
If you’re seeing sand-like granules in your gutters or downspouts, that’s a warning sign your shingles are deteriorating. Granule loss also affects your roof’s appearance, leaving behind bald spots or streaks that make your home look older. Once this process starts, it tends to accelerate, so don’t wait too long to call for an evaluation.
4. Visible Sagging or Soft Spots
Sagging rooflines are a huge red flag. Not only do they reduce curb appeal, they also indicate serious structural concerns. Water damage, mold growth, rotted decking, or compromised rafters can cause your roof to dip or feel spongy underfoot. These problems often go unnoticed until the sag becomes visible or leaks start appearing inside.
A sagging roof is dangerous and can lead to costly repairs if left unchecked. If you see any part of your roofline dipping or notice areas that seem soft or unstable, get it inspected right away. In many cases, the safest and most cost-effective solution is a full roof replacement.
5. Persistent Leaks or Water Stains
A leak is an obvious sign that your roof isn’t doing its job anymore. Sure, minor leaks may be isolated and not cause a lot of damage, but they do cause water intrusion. As more water permeates the structure of your home, you may notice ceiling stains, peeling paint, moldy smells, or water spots in your attic or on upper walls.
Leaks often travel before they become visible, which means the damage could be more extensive than it appears. Flashing failure, compromised underlayment, or shingle wear can all contribute. If repairs haven’t solved the issue—or if new leaks keep appearing—it’s time to seriously consider replacing your roof before bigger problems develop.
6. You’re Constantly Making Repairs
Patching your roof once in a while is normal. But if you’ve had multiple repairs in the past few years—or you find yourself calling a roofer every season—it’s a clear sign the roof is on its last legs. Continual repairs often indicate that the overall system is failing, even if the damage appears isolated.
At some point, the cost of repairs can add up to more than the price of a full replacement. Rather than playing catch-up, investing in a new roof offers a long-term solution with better warranties, higher performance, and peace of mind, especially when it’s installed by a trusted contractor like RGB Construction.
Frequently Asked Questions
1. How long does a roof typically last in South Jersey?
Asphalt shingle roofs in South Jersey typically last 20 to 30 years, depending on installation quality, climate, and maintenance.
2. Can I replace just part of my roof?
While partial replacements are sometimes possible, widespread issues often mean the whole system is compromised. A full replacement may be more cost-effective long-term.
3. Are leaks always a sign I need a new roof?
Not always, but recurring leaks or multiple leak points usually indicate it’s time for a replacement rather than continued repairs.
4. What causes granules to fall off shingles?
Granule loss occurs due to age, sun exposure, storm damage, or poor ventilation. It’s a sign that your shingles are wearing out and may need replacement soon.
5. Can sagging spots be repaired, or do I need a new roof?
Sagging usually indicates deeper structural damage to the decking or rafters. In most cases, a full roof replacement is required to fix it safely.
6. How do I know if the damage is from age or weather?
A licensed roofer can identify whether wear is due to age, storm events, or installation issues. RGB Construction provides free evaluations across South Jersey.
