Home Improvement ROI: Which Projects Actually Pay Off?

Most homeowners approach renovation the same way: pick the room that bothers them most, spend what they can afford, and hope it adds value down the road. That’s a reasonable instinct. But if resale value or return on investment is part of the equation — even loosely — the data tells a story that surprises most people.

The 2025 Cost vs. Value Report, published annually by Zonda and widely cited across the real estate and contracting industry, tracks 28 common remodeling projects and measures how much of each project’s cost homeowners can expect to recoup at resale. The findings consistently challenge conventional wisdom about where renovation money is best spent.

Here’s what the numbers actually say — organized by project type, with honest context for what the table doesn’t tell you.

The big picture: exterior beats interior, every year

Before getting into specific projects, the single most useful thing to understand about home improvement ROI is this: exterior replacement projects outperform interior remodels, consistently and significantly.

In 2025, eight of the top ten highest-returning home improvement projects are exterior replacements. That’s not a fluke — it’s a pattern that has held for years, and it makes intuitive sense once you think about it from a buyer’s perspective. Buyers form their first impression before they walk through the door. Appraisers factor in condition and curb appeal before they measure square footage. A home that looks well-maintained from the street signals to everyone involved that the less visible systems are probably in good shape too.

The other reason exterior wins: labor costs are generally lower for exterior replacement projects than for complex interior remodels, which means a higher proportion of what you spend translates into perceived value rather than construction cost.

ROI by project: the 2025 snapshot

Here’s where things stand this year, from highest return to lowest:

National averages from the 2025 Cost vs. Value Report. Local market conditions vary.

Now let’s go through each category with the context that makes those numbers useful.

Curb appeal and exterior — the highest ROI category

Garage door replacement leads the entire report in 2025 at 268% ROI — up 74% over last year. On an average cost of around $4,500, that’s an extraordinary return, and it illustrates the core principle: low cost, high visibility, strong buyer impact. A garage door is one of the first things a buyer sees in photos and in person. An updated one signals a cared-for home. An outdated or damaged one does the opposite.

Steel entry door replacement comes in at 188% or more, at an average cost of roughly $2,355 — making it the most affordable high-return project on the list. If you’re looking for the single lowest-cost, highest-return improvement before listing a home, this is it.

Fiber-cement siding delivers 114% ROI — one of the few projects that returns more than it costs. It’s durable, low-maintenance, and has broad buyer appeal. Vinyl siding replacement comes in just behind at 97%, a solid mid-range option that meaningfully improves both appearance and energy performance.

The takeaway from this category: if your goal is maximum return on minimum spend, start outside. The curb appeal projects on this list consistently outperform the interior renovations that get far more attention.

Kitchen — where scope is everything

The kitchen is where most homeowners think the big ROI lives, and it’s where the data delivers the most important correction.

A minor kitchen remodel — cabinet refacing, new countertops, updated appliances, fresh hardware — returns 113% nationally. It’s one of the only interior projects in the top five, and it works because the investment is modest relative to the impact. Buyers respond to a kitchen that feels fresh and functional. They don’t need it to be a showroom.

A major kitchen overhaul — moving walls, custom cabinetry, high-end appliances, full layout changes — returns approximately 38%. On an average cost of $85,000, that means roughly $32,000 recouped at closing. You spend $85,000 and get back about a third of it in added home value.

The rule of thumb worth remembering: if a kitchen project involves moving walls or changing the layout, the ROI math almost never works in your favor at resale. The minor remodel is the play. Spend smart, not big.

Outdoor living — underrated and trending up

Wood deck addition comes in at 95% ROI, making it one of the stronger returning projects on the list. Post-pandemic, usable outdoor space has become a meaningful buyer expectation rather than a bonus. A well-built deck in good condition is now closer to a baseline than a differentiator in many markets.

Backup power generator entered the top 10 for the first time in 2025, with ROI exceeding 100% in hurricane-prone and storm-affected regions. In markets where severe weather is a real and recurring concern, buyers increasingly factor energy resilience into their assessment of a home’s value.

Patio additions and outdoor kitchens are worth considering for livability but carry lower and less consistent resale returns. As with most projects, know whether you’re optimizing for how you live in the home or what it sells for — those are often different calculations.

Bathrooms — solid but not spectacular

A midrange bathroom remodel returns around 80% nationally — respectable, particularly on a home with only one full bath where an addition or significant update meaningfully expands the home’s functional appeal.

Upscale bathroom remodels drop to 60% or lower. Luxury tile, custom fixtures, heated floors — these add real personal enjoyment but rarely translate dollar for dollar at resale. Buyers appreciate a bathroom that looks clean, functional, and updated. They don’t consistently pay a premium for finishes that exceed the neighborhood standard.

The best ROI approach in a bathroom: new fixtures, a double vanity if space allows, updated tile, fresh paint. Refresh without a full gut job, and you’ll capture most of the upside at a fraction of the cost.

Roofing — the defensive investment

Asphalt roof replacement returns 65–70% nationally — not the top of the chart, but the framing matters here.

A roof that’s flagged on a buyer’s inspection report is one of the most consistent deal-killers and price-reduction triggers in residential real estate. Buyers negotiate aggressively against a roof that’s near end of life — often deducting more than the actual replacement cost, because they’re pricing in the uncertainty and inconvenience. Replacing before listing eliminates that leverage entirely. The ROI isn’t just what you gain — it’s also what you protect.

There’s also livability ROI to consider. A quality roof replacement with proper ventilation and reflective shingles measurably reduces cooling costs, particularly in warm climates. Impact-resistant options can reduce homeowner insurance premiums by 20–35% annually. Those returns don’t show up in the resale data but are real and compounding over the life of the roof.

Energy efficiency — the slow-burn ROI

Attic insulation is one of the rare projects that pays back primarily through ongoing savings rather than resale value — and it does so relatively quickly. Reduced heating and cooling costs, potential energy tax credits, and improved HVAC system longevity make it a sound investment for long-term owners regardless of what the resale data says.

Window replacement returns 65–70% at resale, but the energy savings and comfort improvement are the stronger argument for most homeowners who aren’t planning to sell imminently.

Rooftop solar delivered the second-lowest ROI in the 2025 report nationally — below 35% in most regions. The energy savings argument for solar can be compelling over a long enough time horizon, but as a resale investment, buyers don’t consistently value it at installation cost. If you’re considering solar, run the math on energy savings rather than resale return.

What to avoid if ROI is the goal

Swimming pools are the most common example of a project with high personal enjoyment and low to negative financial return. In most markets, a pool adds maintenance cost that buyers factor against the purchase price. There are exceptions — certain climates, certain price points, certain buyer pools — but as a general rule, don’t build a pool for the ROI.

Highly personalized renovations narrow your buyer pool. Bold design choices that reflect your taste work against you at resale because they require buyers to either share that taste or mentally price in the cost of undoing it.

Over-improving for the neighborhood is real and common. A $150,000 renovation on a $300,000 house in a neighborhood where homes sell for $320,000 will not return like the same renovation on a house in a $600,000 neighborhood. The ceiling in your market is set by your neighbors, not by the quality of your finishes.

Incomplete projects actively hurt resale value. A half-finished renovation raises more buyer concerns than a dated but intact original. If you start it, finish it before listing.

A simple framework before you spend

Three questions worth asking before committing to any project:

1. Are you improving to sell or to stay? The calculation changes significantly with your timeline. Long-term owners should weight livability ROI — energy savings, reduced maintenance, comfort — more heavily than resale return. Sellers within one to two years should weight the resale data more heavily and focus on projects that remove buyer objections rather than add personal amenity.

2. Is the project in line with your neighborhood’s comp values? Spend to match the neighborhood, not to exceed it. The market sets the ceiling.

3. Are you addressing a functional need or a cosmetic preference? Functional improvements — roofing, HVAC, electrical — protect resale value even when they don’t visibly add to it. A failing system is a liability that suppresses sale price. Fixing it is defensive ROI that doesn’t show up in the table but absolutely shows up at closing.

One honest note to close on: the projects homeowners love most are often the ones with the weakest financial return — and that’s completely fine. A home is where you live, not just an asset to optimize. The ROI data is most useful not as a ceiling on what you can enjoy, but as a reality check on what you can expect to recover. Go in with clear eyes, and the math doesn’t have to be a disappointment.

Frequently asked questions

What home improvements have the best ROI in 2025? Exterior replacement projects lead the field. Garage door replacement tops the 2025 Cost vs. Value Report at 268% ROI, followed by steel entry door replacement at 188%+, and fiber-cement siding at 114%. Among interior projects, a minor kitchen remodel is the standout at 113%.

Do kitchen renovations add value to your home? Minor kitchen remodels return around 113% — genuinely good ROI. Major overhauls average around 38%. The scope of the project matters far more than the category: a modest refresh almost always outperforms a full gut renovation at resale.

Is it worth renovating before selling? It depends on what you’re renovating. Exterior projects, minor kitchen updates, and fixing functional issues like roofing or HVAC tend to pay off. Major interior overhauls and highly personalized projects tend not to. The safest bet is addressing anything a buyer’s inspector will flag before it becomes a negotiating point.

What is the ROI on a bathroom remodel? A midrange bathroom remodel returns around 80% nationally. Upscale remodels drop to 60% or lower. Updated fixtures, tile, and vanity — without a full gut — typically capture most of the upside at a fraction of the cost.

Do swimming pools add value to a home? In most markets, no — or minimally. Pools add ongoing maintenance costs that buyers factor against the price. They may add value in specific climates and price points, but they shouldn’t be built as a resale investment.

What exterior improvements add the most home value? Garage door replacement, entry door replacement, and new siding consistently lead the field for exterior ROI. All three are relatively affordable compared to interior remodels and return more than they cost in most markets.

Is solar worth it for home resale value? Not primarily. Solar delivered below 35% ROI nationally in the 2025 report. The stronger argument for solar is energy savings over time, not resale return. Run the math on your utility costs and local incentives rather than on what it adds at closing.
