Quick Answer: Repair your roof if the damage is small, the roof is under 15 years old, and the fix costs less than half of what a full replacement would run. Replace your roof if the damage is widespread, the roof is past 20 years, or repair costs keep adding up. When in doubt, get a professional inspection and ask for an honest recommendation.
If you are wondering whether you should repair or replace your roof, you are not alone. It is one of the most common questions Iowa homeowners ask after a storm rolls through or after they notice something that doesn’t look right. The answer is not always obvious, and the wrong call can cost you thousands.
Andrew’s Roofing has been helping Des Moines homeowners make this decision for 18 years. Sometimes we tell people their roof just needs a repair. Sometimes we tell them it is time for a replacement. Here is how we think through it, and how you can too.
When Should I Repair My Roof Instead of Replacing It?
A repair makes sense when the damage is small and the rest of your roof is still in solid shape. Think of it like fixing a pothole instead of repaving the whole driveway.
A few missing or damaged shingles after a windstorm is a repair. A small leak around a pipe vent or chimney flashing is a repair. A section of flashing that came loose or corroded is a repair. These are targeted fixes that a good roofer can handle in a few hours.
Repairs also make sense when your roof is relatively young. If your roof is under 15 years old and the issue is isolated, there is no reason to tear the whole thing off. Fix the problem, keep an eye on it, and move on.
A typical roof repair in the Des Moines area runs $400 to $1,500 depending on what needs to be fixed. That is a fraction of what a full replacement costs, and it can buy your roof years of additional life if the rest of the system is healthy.
When Should I Replace My Roof Instead of Repairing It?
Replacement makes sense when the damage is widespread or the roof has reached the end of its useful life. Here are the situations where a replacement is the smarter move.
Your roof is over 20 years old. Most asphalt shingle roofs in Iowa last 20 to 30 years depending on the material and how many storms they have been through. If your roof is approaching that range and showing signs of wear, repairs start becoming a temporary fix on a system that is aging everywhere at once. For a deeper look at what to expect from different materials, check out our guide on how long a roof lasts in Iowa.
You are calling a roofer more than once every couple of years. Frequent repairs are a sign that the roof is failing in stages. Each fix solves one spot, but the rest of the roof is running on the same aging timeline. At some point the math stops working in your favor.
You can see widespread damage from the ground. Curling shingles across the whole roof, large bare patches where granules have worn away, or sagging sections are all signs that a repair won’t cut it.
You have water damage inside the house. Dark spots on your ceiling, mold in the attic, or peeling paint near the roofline all point to water getting through. If the leak is coming from a failing system and not just a single entry point, replacement is usually the answer.
The 50% Rule: How Roofers Decide
There is a widely used guideline in the roofing industry that makes this decision simple. If a single repair costs more than 50 percent of what a full replacement would cost, replace the roof. The National Roofing Contractors Association is the leading authority on roofing standards, and this rule holds up in practice every time.
Here is why it works. If you are already paying half the price of a new roof just to fix part of the old one, the other half of that old roof is aging at the same rate. It will need attention soon. Spending the remaining 50 percent gets you an entirely new roof with decades of life and a full manufacturer warranty.
For example, if a full replacement would cost $12,000 and the repair estimate comes in at $7,000, that is 58 percent. Replace. For just $5,000 more, you get a brand new system instead of a patched old one with aging components everywhere the repair did not touch.

What About Storm Damage? Should I Repair or Replace After Hail?
Iowa hail changes the equation. Storm damage operates by different rules than normal wear and tear.
When hail hits an asphalt shingle, it knocks granules off at the impact point. The strike may not cause an immediate leak. But the exposed asphalt underneath breaks down faster. A hail event in May that removes granules across your roof won’t produce visible leaks that summer. By the following spring, those shingles are brittle and failing.
If a storm damaged your roof and your insurance covers it, replacement is usually the right call. Your policy may cover most of the cost, and you get a fresh start with new materials and a new warranty. If you are not sure whether your roof took hail damage, our guide on how to spot hail damage on your roof in Iowa walks through what to look for.
Filing a claim is a separate decision. We walk through the honest version of when to file and when to hold off in our article on whether to file a roof insurance claim in Des Moines.
If You Do Replace, Consider the Upgrade
If you decide a replacement is the right move, that is also the best time to upgrade your materials. You are already paying for tear-off, labor, and installation. The difference between standard shingles and Class 4 impact-resistant shingles is just the material cost.
Class 4 shingles last longer, survive Iowa hail better, and qualify for an insurance discount that can save you hundreds a year. We break down the full math in our article on Class 4 shingles and the Iowa insurance discount. And if the upgrade stretches the budget, our roof financing and payment plans in Des Moines can spread the cost out.
How to Get a Straight Answer
The best way to know whether your roof needs a repair or a replacement is to have a qualified roofer look at it. Not from the ground. Not from a photo. Up on the roof, checking the shingles, the flashing, the decking, and the ventilation.
The problem is that some roofers push replacements when a repair would solve the problem. Others push cheap repairs to get a quick job when the roof actually needs to come off. You want a roofer who tells you the truth even when the truth is cheaper for you. Check out our roofing services to see how we handle both repairs and full replacements.
