Washington sits high on the bluffs where Highway 47 crosses the Missouri River, and that perch is exactly why metal makes sense on so many homes here. The river valley funnels straight-line wind up the channel and lifts it over the steep older roofs above the riverfront and the historic brick blocks downtown, the kind of exposed, wind-raked slopes where an asphalt shingle starts surrendering tabs. A 26-gauge standing-seam panel locks down with concealed clips that hold through that wind instead of lifting at the edges, and it does not shed granules the way a shingle does when the gusts off the water keep working it season after season.

Metal is not a side service Emmendorfer farms out in Washington. Founder Matt Emmendorfer started roofing in 1990, his son Tom is based right here in Washington, and our second family office runs in town under the original Emmendorfer Roofing name. Tom and the in-house crew set the panels themselves, which matters because a metal roof lives or dies on the details, the clip spacing, the seam crimp, the custom-bent flashing where a porch ties into a turn-of-the-century house up the hill. A storm-chaser who parked downtown after the last hailstorm cannot fake thirty-five years of knowing how a Washington roof actually fails.

How it works

What our metal roofing includes in Washington

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

Washington roofs rarely die from one storm, they die from the stack, and metal is built to break that cycle. Spring and early-summer hail and river-valley wind bruise the shingles, then a hard Missouri winter of freeze-thaw works the bruises until seams and nail heads loosen, and the next April hail finds the opening. The March 2025 storm system that put Franklin County under a federal disaster declaration drove large hail and 75-plus mph straight-line winds across this whole county, working roofs from one end of it to the other. A standing-seam steel roof takes that hit and keeps shedding water where a shingle slope loses its protective granules, and with hidden fasteners there is nothing exposed to back out through Washington's temperature swings. For the steep exposed slopes above the riverfront, or a homeowner near the fairgrounds who never wants to climb a ladder over this roof again, metal is usually the honest answer.

FAQ

Metal Roofing in Washington: questions

For the exposed, wind-raked slopes up on the Washington bluffs, often yes. The Missouri River valley funnels straight-line wind that lifts shingle tabs over time, and a hidden-fastener standing-seam panel holds down through it. Metal also sheds the spring hail and survives the winter freeze-thaw that ends a shingle roof early. For a home you are selling within fifteen years, a quality architectural shingle is usually the smarter spend, and Tom will tell you that on the roof.
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. We walk your actual Washington roof and put a real written number, with the panel profile and color named, in front of you before any work begins.
Heavy hail can leave cosmetic dents, but steel resists the puncturing and granule loss that ends an asphalt roof. The March 2025 storms drove large hail and damaging winds across the county, the kind of weather that bruises shingles. A standing-seam Washington roof takes that hit and keeps shedding water, where a shingle slope loses the granules that protect it and starts the slow failure.
Yes. A lot of our Washington metal work is partial, a standing-seam detail on a low-slope porch that shingles cannot protect on an older home up the hill, or an exposed-fastener panel on a barn, shop, or garage out toward the county. 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 noise. Most Washington homeowners say a properly installed metal roof sounds no louder inside than their old shingle roof did.
If hail or wind caused the damage, often yes. Tom Emmendorfer, based right here in Washington, documents the damage, files your 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 upgrading to metal and cover the difference. Under Missouri law no roofer can pay or waive your deductible, so be wary of anyone in town who offers to.
