New Roof Return on Investment Calculator
How much of a new roof comes back at resale, and what it saves before then.
Default is the 2025 Cost vs Value national figure for asphalt shingle roofing replacement (67.5%), cited in the article below. Adjust for your market.
Value recovered at resale
$10,800
Resale recovery is only part of the return. A documented new roof with a transferable manufacturer warranty and our 50-year workmanship warranty removes the biggest inspection objection buyers raise, and it ends the repair, leak and insurance-claim cycle an aging roof runs on.
A new asphalt shingle roof recovers about two thirds of its cost at resale. The 2025 Cost vs. Value Report from Zonda, publisher of Remodeling magazine, puts the national figure at 67.5%: a $31,871 roofing replacement returned $21,501 in resale value. The calculator above applies that recovery rate, or any rate you choose, to your roof cost and shows the value recovered, the net cost after resale, and the returns that never show up on a closing statement. I am Aaron Scott, a licensed Michigan residential builder and the owner of Roofing Army. Here is what the number means and what it leaves out.
What does the new roof ROI calculator estimate?
You enter the roof cost and a resale recovery percentage. The default is 67.5%, the 2025 Cost vs. Value national figure for asphalt shingle roofing replacement. The calculator returns the dollar value recovered at resale, the net cost of the roof after that recovery, and a breakdown of the non-resale returns: insurance, energy, and avoided repairs. Those last three are shown as categories to think through rather than dollar figures, because they depend on your policy, your attic, and the condition of the roof you are replacing.
How does the calculator get its numbers?
The resale math is a single multiplication: roof cost times the recovery rate is the value recovered, and roof cost minus that is the net cost. The recovery rate comes from the Cost vs. Value Report, which surveys real estate professionals on the resale value of common remodeling projects and compares it to the project's cost. For 2025, the asphalt shingle roofing replacement line was a $31,871 job cost against a $21,501 resale value, or 67.5% recouped. The same report put a metal roof replacement at $51,865 with $25,972 recovered, or 50.1%.
Two things to keep in mind about that percentage. It is a national average, and it describes a home sold soon after the roof is installed. If you stay ten more years, the roof is ten years older when you sell, and the resale premium shrinks, while the other returns below grow. The calculator lets you change the rate for exactly that reason.
What does the ROI look like on a real Michigan roof?
The national job cost in the report is higher than most roofs we install, because it prices a 3,000 square foot roof at national labor rates. Our job gallery publishes the real price of every project, so let us use those:
| Project | Real price | Recovered at 67.5% | Net cost after resale |
|---|---|---|---|
| Oxford, South Glaspie St (2,480 sq ft) | $15,689.90 | $10,590.68 | $5,099.22 |
| Rochester, Longford Drive (3,030 sq ft) | $18,440.16 | $12,447.11 | $5,993.05 |
| Cost vs. Value national example | $31,871.00 | $21,512.93 | $10,358.08 |
The Rochester roof is almost exactly the size the report models, at 3,030 square feet, and it cost $18,440.16 instead of $31,871. At the same 67.5% recovery, the net cost of that roof after resale is about $6,000. That is the number to compare against what an old roof costs you in the years before you sell.
What returns does resale value leave out?
The Cost vs. Value percentage measures one thing: what a buyer pays for a house with a new roof versus one without. It says nothing about the years you live under it. Three returns the calculator flags but cannot price for you:
- Insurance. Carriers increasingly move older roofs to actual cash value coverage or roof payment schedules, which means a hail claim on a 17 year old roof pays a fraction of a claim on a new one. Some carriers will not write a new policy on a roof past a certain age at all. Ask your agent what a new roof changes on your policy; our guide to how Michigan insurance treats an aging roof covers the ACV problem.
- Energy and ventilation. A replacement is the one time it is cheap to fix attic airflow. We do a ventilation analysis on every estimate because a roof that bakes in July and breeds ice dams in January costs money every month. See our attic ventilation service for what that involves.
- Avoided repairs. The last five years of an asphalt roof's life are the expensive ones: emergency tarps, interior drywall, insulation soaked by a leak you did not see. A roof replaced on schedule skips that spending. Our repair or replace guide explains how to tell when you are in that window.
Does a new roof help sell a house in Southeast Michigan?
On the ground, the resale value is only part of it. A roof at the end of its life shows up on the inspection report, and a buyer's lender or insurer can make it a condition of closing. That turns a roof from a negotiation into a requirement, usually on the seller's timeline and at whatever price a rushed replacement costs. Replacing it before listing, with a warranty the buyer can see in writing, removes that leverage. Every full replacement we install carries a 50 year workmanship warranty that transfers one time to the next homeowner within the first ten years, and we register the manufacturer warranty on every job. Details are on our warranty page.
What can the calculator not see?
Your local market, your buyer, and your timeline. A new roof on a well-kept colonial in Birmingham and the same roof on a ranch in Madison Heights recover different amounts in dollars, even at the same percentage, because the roof is a different share of the home's value. The calculator also cannot tell you what your roof will cost, which is the input everything else depends on. Our Michigan roof cost guide gives real ranges, and if you want to spread the cost, the roof financing calculator shows the monthly payment on the plans we offer.

Recovery percentages are only as good as the cost you multiply them by. We give every homeowner five written quotes at different price points, so you can run the calculator on a real number instead of a national average.

Frequently Asked Questions
How much of a new roof's cost do you get back when you sell?
The 2025 Cost vs. Value Report from Zonda, publisher of Remodeling magazine, found an asphalt shingle roofing replacement recouped 67.5% of its cost at resale nationally: a $31,871 job returned $21,501 in resale value. Metal roofing replacement recouped 50.1%. Actual recovery depends on your market and how soon after the replacement you sell.
Does a new roof increase home value in Michigan?
It adds resale value, and just as importantly it removes a common closing obstacle. An old roof flagged on an inspection can become a lender or insurer condition, forcing a replacement on the seller's timeline. A new roof with a workmanship warranty that transfers to the buyer takes that off the table.
Is a metal roof a better investment than asphalt for resale?
Not on resale alone. The 2025 Cost vs. Value Report shows metal roofing replacement recouping 50.1% versus 67.5% for asphalt, and metal costs roughly two to three times as much per square foot on our own jobs. Metal makes sense for a long-horizon owner who wants a roof that outlasts asphalt, not as a resale play.
What returns does a new roof provide besides resale value?
Insurance coverage that pays replacement cost instead of depreciated value, the chance to correct attic ventilation and reduce ice dams and cooling load, and the repairs, tarps, and interior damage you avoid by not running an asphalt roof past the end of its life.
Should I replace my roof before selling my house?
If the roof is near the end of its life, usually yes, because a buyer will discount for it at least as much as it costs and may make replacement a condition of closing. If the roof has years left, a documented inspection and any needed repairs are generally the better use of money.
