How Much Value Will Exterior Renovations Add to Your Home?

 If you're weighing an exterior home remodeling, you probably don't want to hear that it "boosts curb appeal." You want to know the actual number: how much value does this add, and is it worth what it costs?

The short answer is that exterior projects consistently deliver some of the best returns in all of home remodeling, often beating out kitchens, bathrooms, and other interior work by a wide margin.

Here's why, broken down by project type, with real numbers behind each one.

Why Exterior Projects Outperform Interior Ones

A buyer forms an opinion about a home before they ever walk through the front door. Appraisers factor in visible condition, not just square footage, and real estate agents consistently place more weight on curb appeal when pricing a home than most homeowners expect. Exterior projects also tend to require less specialized labor than a full kitchen or bath remodel, which keeps costs lower relative to the value they add.

According to Remodeling Magazine's 2025 Cost vs. Value Report, the industry-standard study comparing project cost to resale value across the country, 8 of the 10 highest-ROI home improvements nationally are exterior projects. A major kitchen remodel, by comparison, typically recoups well under half its cost.

Here’s how the exterior remodel categories stack up.

Garage Doors: The Highest Return in All of Home Remodeling

For the second year in a row, garage door replacement returned more value than any other home improvement project in the country, at 268% ROI. A homeowner who spends roughly $4,700 on a new garage door adds about $12,500 in resale value, more than double the cost.

It's a fast, relatively inexpensive project with an outsized visual impact, which is exactly why it tops the list year after year.

Entry Doors: A Small Change With Outsized Impact

A steel entry door replacement returns 216% ROI nationally. Like a garage door, it's a focal point, it's often the first thing a visitor or buyer actually touches, and it sets the tone before anyone sees the rest of the house.

Pairing a new entry door with better lighting and a refreshed house number or address plaque tends to amplify the effect further.

Stone and Siding: Where Material Choice Matters

Manufactured stone veneer returns 208% ROI, making it one of the strongest exterior investments available, and one that doesn't require replacing an entire home's siding to make an impact. Applying stone to a focal section, an entryway, a lower level, one end of the house, can transform a facade without the cost of a full re-side.

Vinyl siding, when a full replacement is needed, returns 97% ROI, still a strong number, and typically the right call when siding is worn, damaged, or outdated across the whole home rather than in one section.

Roofing: A Real Return, With an Iowa-Specific Catch

Roofing is a different story than the categories above. Nationally, a roof replacement returns about 68% of its cost, a solid return, but the lowest of the major exterior categories.

Here's the part that matters specifically if you're in Iowa: roofing ROI varies significantly by region. In the West North Central region, which includes Iowa, roof replacement returns closer to 54%, one of the lowest recoup rates in the country. Some southern and western regions see returns well above 80% for the same project.

That gap doesn't mean skip the roof when it needs replacing, a failing roof is a maintenance issue regardless of ROI. But it does mean a roof alone typically isn't the highest-return project available to an Iowa homeowner.

 At Zenith Design + Build , roofing is offered as part of larger renovation projects starting at $50K, so in practice a roof replacement usually comes bundled with siding, stone, or trim work rather than as a standalone job, which tends to deliver a better combined return than tackling a roof in isolation

Small Details: House Numbers, Lighting, and Garage Door Trim

Not every high-impact exterior change is a full project. Updated house numbers, light fixtures, and small architectural details like squared-off garage door trim or the removal of an outdated window shape can meaningfully change how a home reads, often for a fraction of the cost of a full remodel.

What This Looked Like on a Real Home

After

We recently took on a West Des Moines home that didn't need a full exterior teardown to look completely different. Over about two months, we added stacked stone to one end of the house, brought in cedar accents along the upper level and around the front entry post, and swapped out the house numbers, light fixtures, and a rain chain for more modern versions.

Two of the smallest changes made some of the biggest visual impact: squaring off the angled corners on the garage door, and removing an outdated half-moon window from the upper level. Neither change was expensive on its own, but combined with the stone and cedar accents, the home went from dated to the kind of house that stops you mid-walk.

That project touches nearly every category above: stone veneer, garage door detailing, lighting and fixture updates, all bundled into one focused, two-month timeline rather than a full exterior overhaul.

What This Means If You're Planning a Project

If your roof is failing, fix the roof first. That's a maintenance decision, not a financial one.

But if you're choosing where to invest for value, the data points toward starting with the highest-return categories first: a garage door, an entry door, targeted stone or siding accents, the kind of focused changes that transformed the home above without a full exterior teardown.

FAQ

What exterior renovation adds the most value to a home? Garage door replacement currently has the highest ROI of any home improvement project nationally, at 268%, according to the 2025 Cost vs. Value Report.

Is a roof replacement worth it for resale value? Nationally, roof replacement recoups about 68% of its cost. In Iowa and the broader West North Central region, that number is closer to 54%, lower than most other regions. It's still worth doing when a roof needs it, but it isn't the highest-return project on its own.

Should I replace my siding or my roof first? If both need work and budget is limited, siding typically returns more of its cost (97% nationally) than roofing (68% nationally, lower in Iowa). If your roof is failing, it takes priority regardless of ROI.

Do small exterior changes actually make a difference? Yes. Details like squaring off garage door corners, updating light fixtures, or adding stone accents can meaningfully change a home's look without a full exterior overhaul.

Does bundling exterior projects save money? Often, yes. Combining projects like roofing and siding means one crew handles related work together, which tends to be more efficient than scheduling separate jobs, and gives the home a cohesive finished look.
