Can a new metal roof go over existing asphalt shingles?

Often, if the deck under the shingles is sound and the local building office allows a roof-over. Metal panels weigh less than most roofing materials, so the added load is usually small. The tradeoffs: the old roof cannot be inspected once covered, and fastener lengths must account for the shingle layer. A tear-off costs more but starts the new roof from a checked deck.

How much does replacing a roof with metal cost in Wyoming?

Published local figures are five-figure. Excel Roofing, a contractor with a Casper office, lists standing seam at $1,283 per square, about $38,475 on a typical 30 square Casper roof. Interstate Roofing puts a Cheyenne standing seam replacement on a typical 2,000 square foot home at roughly $15,000 to $25,000 or more. Both are contractor-published figures, not statewide averages, and your roof will move them.

Is it worth replacing asphalt with metal on a windy Wyoming site?

The wind case is real. The Wyoming Climate Atlas from the State Climate Office ranks Wyoming first in the US in annual average wind speed, with frequent winter runs of 30 to 40 mph and gusts of 50 to 60 mph. Asphalt sheds tabs in exactly that weather, while a tested metal assembly is engineered against uplift. On exposed sites the replacement math usually favors metal.

Do I need a permit to replace a roof in Wyoming?

It depends on the jurisdiction, because Wyoming has no mandatory statewide building code. Sheridan, for example, requires a building permit for projects over $3,000 and keeps roofing on its simple-permit list, while Casper routes roofing permits through its Building Inspection Division. Call the city or county building office before work starts; the locations pages on this site name the office for each town.

Can I cancel a roof replacement contract signed after a hailstorm?

For storm damage work, yes, within limits. Wyoming Statute 40-12-705 gives homeowners three business days after signing an exterior storm damage repair contract to cancel, or three business days after the insurer denies the claim in whole or in part. The same law bars a contractor from paying or rebating any part of your deductible. It applies statewide, license or no license.

Replacement

Metal roof replacement in Wyoming

Sooner or later, most Wyoming roofs lose an argument with the wind. Around Casper and across the Natrona County plains the story repeats itself: an asphalt roof drops tabs at the corners after every hard blow, the patch bills stack up, and the homeowner starts pricing a roof that does not need the same phone call every spring. Replacement is that decision, and in this state it usually means weighing metal against one more round of shingles.

This page walks the decision in order: reading the signs, tear-off against roof-over, choosing the replacement system, published cost figures for Casper and Cheyenne with sources attached, and the local rules, in a state that licenses no roofers. The full statewide picture, wind numbers included, is the Wyoming metal roofing guide.

Reading the end of a roof

Wind is the usual executioner. Per the Wyoming Climate Atlas wind chapter from the State Climate Office, Wyoming ranks first in the US in annual average wind speed at 12.9 mph, and winter brings frequent periods of 30 to 40 mph wind with gusts of 50 to 60 mph. Uplift concentrates at eaves, rakes, ridges, and corners, so that is where a tired roof confesses first: shingle tabs gone after a gust event, creased tabs that flap but have not torn off yet, nail heads showing where edge trim lifted.

Other verdicts arrive slower. Granule loss that exposes the mat, hail bruising an adjuster has already written up once, a leak that moves every time it is patched, or, on an older exposed fastener metal roof, screw lines that no longer bite and rust blooming at the panel laps. Any one of these can justify a fix, and metal roof repair covers those calls. A cluster of them on a roof past its second decade usually reads replacement.

Tear-off or roof-over

A full tear-off strips to the deck, and it buys certainty: rotten sheathing gets found and replaced, the underlayment starts clean, and edge metal goes onto framing that has been looked at. On a wind-exposed site that certainty matters, because uplift resistance is a chain that starts at the deck, runs through the clips and fasteners, and ends at the seam. The build sequence itself is covered on metal roof installation.

A roof-over, metal installed over the existing shingles, saves the tear-off and disposal cost, and metal's low weight makes it structurally plausible where heavier materials are not. The tradeoffs are real: the deck cannot be checked, fastener lengths change, and the local building office decides whether it is allowed at all. Neither answer is universally right. The deck's condition and the jurisdiction decide.

What the replacement system should be

The choice inside metal is the same fork the whole site turns on. Standing seam panels interlock along raised vertical seams, fasteners concealed, riding clips that let panels move with temperature and still hold down, which is why it is the default answer on open, hard-blown ground; standing seam metal roofing makes that case in full. Exposed fastener panels cost less and screw straight through the face on gasketed screws that age in sun and wind.

Whichever profile, ask every bidder for the tested assembly, not adjectives. Per Sheffield Metals' uplift testing overview (manufacturer-published), UL 580 rates roof assemblies in classes 30, 60, and 90, UL 1897 continues that test to failure, and ASTM E1592 pressure-tests standing seam systems; Sheffield states UL 90 is its minimum standard for installed systems. How those ratings map to your county's design wind values is the subject of wind-rated roof systems.

What replacement costs, with sources

Every figure below is a published number cited to the page that carries it and labeled by who published it. None is a statewide average, and pitch, access, and roof complexity move all of them. The pattern worth noticing: standing seam runs roughly three to four times an entry asphalt roof, and the gap narrows against the Class 4 impact-resistant shingles adjusters favor in hail country.

Replacement option	Published figure	Publisher
Standing seam, Casper, installed with tear-off and disposal (1.5 inch snap lock, Class 4)	$1,283 per square; about $38,475 on a typical 30 square roof	Contractor-published: Excel Roofing Casper metal cost guide
Asphalt shingle roof, Casper area (the stay-with-asphalt anchor)	$6,000 to $12,000; $9,000 average	Contractor-published: Excel Roofing Casper pricing guide
Standing seam or high-quality metal, Cheyenne, full tear-off and replacement on a typical 2,000 sq ft home	Roughly $15,000 to $25,000 and up	Contractor-published: Interstate Roofing Cheyenne cost guide
Asphalt alternatives, Cheyenne, same page: architectural, and Class 4 impact-resistant	Roughly $9,000 to $14,000; Class 4 roughly $11,000 to $17,000	Contractor-published: Interstate Roofing Cheyenne cost guide
National installed brackets: standing seam; 7/8 inch corrugated exposed fastener	$10 to $16 per square foot; $7 to $12 per square foot	Manufacturer-published: Western States Metal Roofing

The metal premium buys the wind and hail durability this state keeps pointing at, which is the part of the argument the numbers cannot settle alone. On a sheltered in-town lot in Sheridan, one of the calmer reporting stations in the Climate Atlas, the cheaper roof can be the rational one. On rimrock west of Casper or open ground outside Cheyenne, one more asphalt roof is often a down payment on the next one.

No license stands behind a replacement bid

Wyoming has no statewide license or registration for roofers or general contractors, a point industry licensing guides such as Procore's Wyoming overview state flatly. What exists is city by city. Casper's Building Inspection Division licenses roofing contractors on an ICC exam, at least one year of roofing trade experience, and proof of $250,000/$500,000 personal injury and $250,000 property damage liability insurance. Cheyenne folds roofing into its Class C contractor license, and Laramie, Gillette, Sheridan, and Jackson run their own programs. Outside those cities there is no license to look up.

Permits and design values are just as local, because Wyoming leaves building codes to cities and counties; the full picture is in the Wyoming metal roofing guide. Cheyenne's plan review criteria call for a 115 mph ultimate design wind speed (city plan review criteria, PDF), Natrona County publishes a 105 mph three-second gust basic wind speed for one and two family dwellings (county guidelines), and Sheridan requires a building permit once a project passes $3,000 (city building department). The locations pages name the office for each town, and the bid in your hand should reference your jurisdiction's numbers, not a generic map.

A Jackson replacement is a different animal

In Teton County the replacement conversation changes category before wind even enters it. The county's published design criteria run 120 to 175 psf ground snow load by GIS zone, against roughly 30 psf on the plains, with a 115 mph basic wind speed and Seismic Design Category D. A replacement there is engineered around snow retention, ice, and structure first, which is part of why architectural standing seam dominates the valley, and contractor licenses issued by the Town of Jackson cover both the town and unincorporated Teton County. The Jackson page treats that market on its own terms.

Those storm rules are statute, not courtesy: Wyo. Stat. 40-12-701 through 40-12-706 requires written disclosures in storm damage repair contracts, gives three business days to cancel (including after a claim denial), and bars deductible rebates. Metal roof repair walks through them, since hail claims start there more often than not. And the checklist applies to any bidder, including a roofer we connect you with: we are a free matching service, not a contractor, and how we make money spells out the referral fee that funds this site.
