Metal answers a specific Union problem. Sitting where Highway 50 crosses Highway 47 at the heart of Franklin County, Union catches the full eastern-Missouri storm corridor, and the same spring hail that bruised roofs all across this county in the major March 2025 storm that swept the Franklin County area is exactly where a 26-gauge steel panel earns its keep. A standing-seam roof does not shed granules the way asphalt does on a south-facing slope, and it does not give up its seams through the freeze-thaw winters that work every Union roof from the courthouse downtown to the newer subdivisions on the edge of town.

Because our shop is in Union, the family that sets the panels lives here too. The same in-house crew that does our shingle work runs the metal, which matters more on a metal roof than almost anything else, because metal lives or dies on the clip spacing, the seam crimp, and the flashing at every valley and chimney. A storm-chaser who drove into Union after the last hail event cannot fake thirty-five years of knowing how a Missouri roof actually fails. We have replaced and repaired enough roofs across this county to set a panel that lies true and stays tight for decades.

How it works

What our metal roofing includes in Union

Metal is unforgiving of shortcuts. A panel set wrong telegraphs every mistake for forty years. Here is what happens once you approve the estimate.

  1. Tear off and inspect the deck

    We strip the old roof to the wood and check every sheet of decking. Metal needs a flat, sound substrate to lie true, so any soft or rotten plywood comes out now. We never lay metal over an old roof to save a day, because a wavy deck shows through a metal panel forever.

  2. Lay a high-temp underlayment

    Metal runs hotter than asphalt in the Missouri summer sun, so the field gets a high-temperature synthetic underlayment, with an ice-and-water membrane in valleys, at eaves, and around every penetration. This is the layer that stops the freeze-thaw and ice damming a Franklin County winter throws at the eaves.

  3. Set the panels with hidden clips

    Standing-seam panels lock to concealed clips, not face-driven screws. Nothing penetrates the weather surface, which is the whole point. The clips also let the metal expand and contract through Missouri's temperature swings without buckling or backing screws out the way an exposed-fastener panel does over time.

  4. Crimp the seams and flash every detail

    We machine-seam or hand-crimp the vertical ribs so the panel laps shed water uphill of every fastener. Then we custom-bend flashing for valleys, sidewalls, chimneys, and the roof-to-wall transitions where a porch meets the house. Bad flashing is where most metal roofs leak, so this is where we slow down.

  5. Clean to no footprint

    We magnet-sweep the yard for screws and metal shavings and haul every offcut. Customers tell us our cleanup is our signature. We get in, do the work, and get out without leaving a footprint, the same way we have since 1990.

Local angle

Union runs the full range of housing, and metal does not fit all of it the same way. The steep older roofs near the historic downtown and the exposed rural acreage roofs out toward the county line are where standing-seam earns its higher cost, while a moderate 1990s subdivision roof in town is often better served by a quality architectural shingle. We tell you which one your house calls for on the roof, not after you have signed. A lot of our Union metal work is also partial: a standing-seam detail on a low-slope porch shingles cannot protect, or an exposed-fastener panel on a barn or shop on the edge of town. Whatever the job, the panel and color go on your written estimate before we order a single sheet.

FAQ

Metal Roofing in Union: questions

Standing-seam metal runs roughly $10 to $16 per square foot installed, and exposed-fastener panels around $7 to $12, so metal typically costs two to three times an asphalt roof up front. The trade is lifespan, since a standing-seam roof can outlast two or three shingle roofs. We walk your actual Union roof and give you a real written number before any work begins, and the price you approve is the price you pay.
For the right home, yes. Union sits in eastern Missouri's severe-storm corridor with spring hail, summer straight-line wind, and a hard winter freeze-thaw cycle. Standing-seam metal sheds hail, holds its seams through the temperature swings, and can outlive the mortgage. If you are selling soon or the slope is moderate, a quality shingle is often the smarter spend, and we will tell you that on the roof.
Heavy hail can leave cosmetic dents on a metal panel, but steel resists the puncturing and granule loss that ends an asphalt roof. The March 2025 storms drove large hail and 75-plus mph winds through Franklin County, including nearby Sullivan, the kind of weather that bruises shingles. A standing-seam roof takes that hit and keeps shedding water where a shingle slope loses the granules that protect it.
Yes. A lot of our metal work around Union is partial, a standing-seam detail on a low-slope porch shingles cannot protect, or an exposed-fastener panel on a barn, shop, or garage out on rural acreage. We tie it cleanly into your existing roof and flash every transition. We will quote a full metal roof or a single section, whichever fits your home and budget.
If hail or wind caused the damage, often yes. Tom Emmendorfer documents it, files the claim, and meets your adjuster on the roof here in Union to walk them through it. Your policy typically pays to restore the roof you had, and you can apply that toward upgrading to metal and cover the difference. Under Missouri law no roofer can pay or waive your deductible, so be wary of anyone who offers to.
A properly installed standing-seam steel roof commonly lasts 40 to 60 years, two to three times a typical asphalt roof in this climate. The Kynar finish holds its color for decades, and because the fasteners are hidden there is nothing exposed to back out or rust. That longevity, plus our 20-year workmanship warranty, is the main reason Union homeowners choose metal.
