Sullivan sits right on Interstate 44 where Franklin County meets Crawford County, and that exposed position is exactly why metal roofing earns its keep here. The federally declared March 2025 disaster drove tornadoes, large hail, and straight-line winds over 75 mph across Franklin County and Sullivan caught the worst of it. Hail like that strips the granules off an asphalt shingle and leaves soft bruises that fail quietly over the next year or two. A 24 to 26-gauge standing-seam steel panel takes that same hit and keeps shedding water, which is the whole argument for metal on a town that catches the worst of the stones.

Emmendorfer Exteriors has been setting metal roofs since long before it was a trend out this way. Founder Matt Emmendorfer started as a roofer in 1990, moved the family operation from Overland to Union around 2003, and his sons Tom and Tim run the crews that drive down 44 to Sullivan today. Metal is not a side service we farm out to a sub. The same in-house family crew that does our shingle work sets the panels, which matters because a metal roof lives or dies on the clip spacing, the seam crimp, and the flashing at every valley and chimney. A storm-chaser who found Sullivan on a map after the last hailstorm cannot fake thirty-five years of knowing how a Missouri roof actually fails.

How it works

What our metal roofing includes in Sullivan

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

Sullivan's housing runs from the older homes near the historic downtown and the Meramec Caverns side of town to the newer subdivisions out toward the lake and the rural acreage roofs spread along the county line. That mix is where metal shines, because the exposed, steep, and outbuilding roofs out here are the ones that punish a shingle fastest. A standing-seam panel does not curl in the summer heat off a south slope and does not give up its seams in the freeze-thaw winter that works every roof along the I-44 ridge. For the barns, shops, and low-slope porches that shingles cannot protect, we run an exposed-fastener or low-slope metal detail tied cleanly into the main roof. And on a storm claim, Tom Emmendorfer meets your adjuster on the Sullivan roof and walks them through the damage in person, not over the phone from another county.

FAQ

Metal Roofing in Sullivan: 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 in this climate. We walk your actual Sullivan roof and give you a real written number before any work begins.
For the right home, yes. The March 2025 storms put large hail and damaging winds right over Sullivan, the kind that bruises asphalt shingles and shortens their life. Heavy hail can leave a cosmetic dent in steel, but it does not strip granules or punch through the way it ends a shingle roof. On an exposed I-44 home that keeps catching storms, metal stops the cycle of replacing a roof every few years.
Yes. A lot of our metal work along the Sullivan and Bourbon acreage is partial, an exposed-fastener panel on a barn, shop, or garage, or a standing-seam detail on a low-slope porch that shingles cannot protect. 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.
Almost never on a real installation. A standing-seam roof goes over a solid deck and a high-temperature synthetic underlayment, not bare framing like an old pole barn. The deck and your attic insulation deaden the sound, so most Sullivan homeowners say a properly installed metal roof is no louder inside than the shingle roof it replaced.
If hail or wind caused the damage, often yes. Tom Emmendorfer documents the damage, files the claim, and meets your adjuster on the roof to walk them through it. Your policy typically pays to restore the roof you had, and you can apply that toward metal and cover the difference. Under Missouri Revised Statute 407.725 no roofer can legally pay or waive your deductible, so be wary of anyone in Sullivan who offers to.
Sullivan is a straight twenty-minute run down I-44 from our shop in Union, not a half-day drive from a St. Louis suburb. On an active leak or fresh storm damage we aim to be there the same day to get your house under the dry and look at whether metal or shingle is the smarter spend for you. Call (314) 568-4163.
