Every Memphis homeowner faces this question eventually. Your roof is showing its age. You've got some missing shingles, maybe a leak that showed up after the last storm. The roofer tells you it's time for a repair. But is a repair really enough?
The line between a fix and a full replacement isn't always clear. Here's how we help our customers decide.
The Simple Rule
If the damage is limited to one area and the rest of the roof is in good shape, you can almost always repair it. If the damage is widespread or the roof is near the end of its expected life, replacement is usually the smarter move.
That sounds simple, but here's what you need to look at to make the call.
How Old Is Your Roof?
This is the first question we ask. Asphalt shingle roofs in Memphis typically last 20 to 25 years. If your roof is under 15 years old and has damage from a storm or an isolated leak, a repair makes sense. You've still got years of life left in it.
If your roof is over 20 years old and you're starting to see problems, those problems are going to keep coming. Repairing one leak now doesn't mean another won't show up next month. At a certain age, replacing the whole roof gives you peace of mind that patching just can't provide.
How Much of the Roof Is Damaged?
This matters almost as much as age. A few missing shingles from a wind storm? Easy repair. A section of the roof that took heavy hail damage? If it's isolated to one slope, you might be able to replace just that section.
But if you look at your roof and see problems everywhere, that's a different story. Curling shingles. Bald spots. Granules in every downspout. Those are signs of a roof that's failing across the whole surface. Patching one spot doesn't help when the whole thing is worn out.
Here's a rough guide:
- Less than 30% damaged: A repair or partial replacement might be the right call.
- More than 30% damaged: Most roofers will recommend a full replacement. When you're replacing that much of the roof, it's usually more cost-effective to do the whole thing.
Are You Having Multiple Leaks?
A single leak in one spot can often be repaired. But if you're finding water stains in different rooms, or if the leaks keep happening in different places, the roof's ability to keep water out is compromised across the whole surface.
Multiple leaks almost always mean it's time for a replacement. You can patch one hole, but you can't patch a roof that's failing everywhere.
What's Under the Shingles?
Sometimes the shingles look okay, but the decking underneath is rotted. If water has been getting in for a while and the wood is soft or damaged, a simple shingle replacement won't fix the problem. The damaged decking has to come out and be replaced too.
If the decking damage is extensive, that pushes the project toward a full replacement. At that point, you're already tearing off the old roof and putting down new material. It makes more sense to replace everything at once.
The Financial Side
We know cost is a big factor. A repair costs less upfront. A replacement costs more, but it gives you a brand new roof with a warranty that will last 20-plus years.
Here's how we think about it. If you repair a 22-year-old roof, you're spending money on something that's already near the end of its life. That repair might last a few years, maybe less. Then something else goes wrong and you're paying for another repair. Over a few years, you could spend half the cost of a new roof on patches.
A replacement is a bigger investment upfront, but it's a one-time cost. And you know the whole roof is solid. No surprises.
Can You See the Difference?
This one is about looks. If you replace part of your roof, the new shingles might not match the old ones. The sun fades shingles over time, so a patch can stand out. If that matters to you, a full replacement gives you a uniform look across the whole roof.
When a Repair Is the Right Call
To sum it up, a repair usually makes sense when:
- The roof is under 15 years old
- The damage is from a specific event like a storm
- The damage is limited to one area
- The decking underneath is in good shape
When a Replacement Is the Right Call
A replacement is usually the better choice when:
- The roof is over 20 years old
- Damage covers more than 30% of the surface
- You have multiple leaks in different areas
- The decking has rot or water damage
- You plan to stay in the house for more than five years
Bottom Line
There's no one-size-fits-all answer. Every roof is different, and every homeowner's situation is different. The best thing you can do is have a roofer take a look and give you an honest assessment. We do free inspections and we don't pressure you into one option or the other. We just tell you what we see and let you decide what makes sense for your home and your budget.
If your roof is on the fence between repair and replacement, give us a call. We'll help you figure out the right move.
