The Best Exterior Renovation Projects for Boosting Home Value

The exterior projects that return the most at resale are, by a wide margin, the modest ones: garage door replacement (267.7% of cost recouped), steel entry doors (216.4%), and manufactured stone veneer (207.9%), according to Zonda's 2025 Cost vs. Value Report. Bigger projects like siding, decks, windows, and roofing recoup roughly 60 to 115 percent nationally. Here's how the numbers break down, and how to decide what your own home actually needs first.

What the 2025 Cost vs. Value Data Shows

The Cost vs. Value Report, published annually since 1988, compares the average cost of common remodeling projects against the value real-estate professionals estimate they add at resale. The 2025 edition puts these national figures on exterior work:

• Garage door replacement: 267.7% of cost recouped
• Steel entry door replacement: 216.4%
• Manufactured stone veneer: 207.9%
• Fiber-cement siding replacement: 113.7%
• Vinyl siding replacement: 96.5%
• Wood deck addition: 94.9%
• Composite deck addition: 88.5%
• Vinyl window replacement: 68.5%
• Asphalt roof replacement: about 68%

Two caveats worth knowing before you plan around these numbers. First, they're national averages built from surveys, not guarantees; your market, your home's condition, and the quality of the work all move the result. Second, "cost recouped" only measures resale value. It doesn't count the years you live with a leak-free roof or a deck you actually use, which for most homeowners is the larger share of the value.

Decks: Strong Demand, Solid Returns

A new deck recoups 94.9% of its cost in wood and 88.5% in composite, per the 2025 report. Composite trails on percentage only because it costs more up front; over the years you own it, composite boards from Trex, TimberTech, and AZEK skip the sanding, staining, and board replacement that wood demands, and the manufacturers back them with multi-decade fade and stain warranties. If you plan to stay put, composite usually wins on total cost of ownership. If you're selling within a couple of years, wood gets you the higher percentage back.

Siding: The Big Project That Pays Back Best

Among full-scale replacements, siding leads. Fiber-cement recoups 113.7% nationally and vinyl 96.5%, and either one changes how a house reads from the street more than any other single project. Siding is also protective infrastructure: it's the layer that keeps rain out of your sheathing and framing. Replacement is the moment to fix hidden rot, upgrade the housewrap, and reflash trouble spots, which is where much of the long-term value hides. Common choices in our market include CertainTeed and Alside vinyl, and LP SmartSide engineered wood for homeowners who want a wood look without wood's rot vulnerability.

Roofing: Modest Resale Return, Big Practical Value

A mid-range asphalt roof replacement recoups about 68% of its cost nationally in the 2025 report, roughly $21,500 in resale value on a $31,900 average job. Nobody replaces a roof to turn a profit, and the honest case for a new roof is different: it protects everything under it, it removes the single biggest red flag a buyer's inspector can raise, and some insurers now limit or decline coverage on roofs past a certain age. If your shingles are 20 or more years old, a roof replacement is less an investment decision than a timing decision.

Windows and Doors: Comfort First, Then Value

Vinyl window replacement recoups 68.5% nationally and wood windows 61.2%. The stronger argument for new windows is daily comfort and operating cost: ENERGY STAR estimates that replacing single-pane windows with certified models saves a typical home $101 to $583 a year depending on climate, with smaller savings when you're replacing older double-pane units. Entry doors are the outlier in the data: a steel entry door is one of the cheapest projects in the entire report and returns 216.4% of its cost. We install ProVia entry doors and vinyl replacement windows, and ProVia publishes its energy and durability certifications for every line.

Porches and Porticos: The Project the Data Doesn't Track

National cost-vs-value data has no line item for porches or porticos, so be skeptical of anyone quoting a precise ROI for one. What a covered entry or front porch reliably delivers is a protected doorway, less weathering on your door and trim, and usable outdoor space in the months when an open deck sits empty. Appraisers tend to fold that into general curb appeal, and buyers notice it the moment they walk up.

Why Maryland's Climate Raises the Stakes

Maryland's climate is genuinely demanding on exterior building materials. Summers in Howard and Montgomery counties are hot and humid, accelerating the deterioration of aging siding, rotting wood trim, and degrading caulk around windows and doors. Fall brings heavy rain from nor'easters, and winters in Carroll, Frederick, and Baltimore counties deliver freeze-thaw cycles that stress any material with even minor cracks or gaps.

That seasonal pattern means deferred exterior maintenance compounds quickly. A small siding gap that's easy to ignore in September can let moisture behind the wall in October, freeze and expand in January, and leave you with rotted sheathing by spring. Homeowners in Harford and Anne Arundel counties also deal with coastal influences, salt-laden air and storm wind loads that call for materials rated for moisture and impact resistance.

How to Prioritize When You Can't Do Everything at Once

Most homeowners can't tackle every exterior upgrade at once, and that's entirely reasonable. The key is sequencing projects in an order that protects your investment and avoids doing work twice.

Start with the roof. A failing or aging roof is the most critical threat to the rest of your exterior. Water that enters through a compromised roof can damage siding, rot window frames, and destroy insulation before you ever see a stain on the ceiling. If your roof is more than 20 years old or showing signs of wear, make it the first priority.

Then address the building envelope. Once the roof is sound, focus on siding and windows together if your budget allows. New siding paired with window and door replacement seals the entire exterior in one coordinated project, reducing labor costs and giving you a consistent finished appearance.

Add outdoor living space last. With the envelope protected, a deck, porch, or enclosure becomes a pure lifestyle upgrade rather than a repair. A new deck attached to a house with a failing roof is a liability. The same deck attached to a freshly roofed, re-sided home is a genuine asset.

Before You Hire Anyone

In Maryland, any company performing home improvement work must hold a license from the Maryland Home Improvement Commission, and you can verify a license number through the Department of Labor before signing anything. Beyond the license, ask for a written, itemized estimate, proof of liability and workers' compensation insurance, and the actual manufacturer warranty terms for each product being installed. A company that hesitates on any of those is one worth passing on. For the record: Classic Remodeling holds MHIC license #51277 and has worked in Central Maryland since 1997.
