Metal answers a problem St. Clair homeowners know well. The town sits right on Interstate 44 in the south end of Franklin County, in the severe-weather corridor the National Weather Service watches every April through June, and that is exactly the slope-by-slope abuse a standing-seam steel panel is built to outlast. A 26-gauge panel does not shed granules the way an asphalt shingle does after a hailstorm, does not curl on a hot south-facing slope, and does not pop its seams through the freeze-thaw winters that follow. For a steep older roof near the original town center off Highway 47, or an exposed acreage roof out toward the Bourbeuse River bottoms, that durability is the whole point.

We are based about fifteen minutes northeast in Union, the county seat, so a St. Clair metal job is the same Franklin County we have worked since we moved the family business here from the Overland suburb of St. Louis around 2003. Metal is not a service we farm out to a storm crew that drove down I-44 after a hailstorm. The same in-house family crew that sets our shingle work crimps the seams and bends the flashing, and on a metal roof that matters more than anywhere, because the roof lives or dies on clip spacing, seam crimp, and the flashing at every valley and chimney. Founder Matt Emmendorfer started roofing in 1990, and his sons Tom and Tim run the crews today. Thirty-five years of knowing how a Missouri roof actually fails is not something a weekend outfit can fake on your St. Clair home.

How it works

What our metal roofing includes in St. Clair

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

St. Clair's housing makes metal a slope-by-slope decision, not a blanket sell. A 1990s subdivision ranch off Springfield Road, a steep gabled older home in town, and a long low-slope addition on a wooded country lot each take hail and wind differently, and metal earns its cost on some of them and not others. We walk your actual roof first. For the steep, wind-exposed slopes south and east toward the Meramec and Bourbeuse watershed, for a porch or addition that shingles cannot protect, or for a homeowner who wants to stop replacing roofs every storm cycle, standing-seam is the strongest product we install. If a Malarkey Class 4 impact shingle is the smarter spend for your St. Clair house and your timeline, we will say that on the roof, not after you sign. The panel profile and color go on your written estimate before we order a sheet.

FAQ

Metal Roofing in St. Clair: 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, a standing-seam roof can outlast two or three shingle roofs on a St. Clair home. We walk your actual 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. St. Clair sits in the I-44 severe-weather corridor with spring hail, summer straight-line wind, and a hard winter freeze-thaw cycle. Standing-seam metal sheds hail, holds its seams through temperature swings, and can outlive the mortgage on the exposed slopes south of town. For a home you are selling soon, a quality shingle is often the smarter spend, and we will tell you that on the roof.
Steel resists the puncturing and granule loss that ends an asphalt roof. The federally declared March 2025 storms drove large hail and 75-plus mph straight-line winds across Franklin County, the kind of weather that strips an asphalt slope of its granules. Heavy hail can leave cosmetic dents on a metal panel, but 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 St. Clair and the rural acreage south and east of town 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. 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 barn, so the deck and your attic insulation deaden the sound. Most St. Clair homeowners say a properly installed metal roof sounds no louder inside than the shingle roof it replaced.
If hail or wind caused the damage, often yes. Tom Emmendorfer documents the damage, files your claim, and meets your adjuster on the roof here in Franklin County 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 in St. Clair who offers to.
