Commercial roofing in Washington is its own discipline, and a flat or low-slope roof fails in ways a steep shingle roof never does. A brick storefront on the downtown square near the riverfront, a warehouse along Highway 100, a corncob-pipe-district building, or an office out toward the bypass carries a membrane that has to shed water across a near-flat plane while the Missouri River valley funnels weather straight up the channel. When that membrane bruises or a seam lifts, the leak shows up over your inventory or your point of sale, not a spare bedroom, and a closed day costs a Washington business real money.

We are not a metro outfit driving into Washington for the day. Tom Emmendorfer is based here, our second family office runs in town under the older Emmendorfer Roofing name, and we have sponsored Washington High School sports for years. The family has roofed Washington since 1990, founder Matt Emmendorfer plus sons Tom and Tim, roughly 2,400 Missouri homes and buildings in all, including 306 jobs in 2025. Commercial grew naturally out of that, in Matt's words a lot of TPO and commercial roofing along with metal. The same family that answers the phone is the crew on your roof, never a subcontracted storm chaser hired by the week.

How it works

What our commercial roofing includes in Washington

A commercial roof has to keep working while your business does. Here is how we handle it once you approve the estimate.

  1. Full roof survey and moisture check

    We get on the roof and walk the entire membrane, checking seams, drains, scuppers, curbs, pitch pans, and edge metal. We document soft spots and trapped moisture with photos and drone footage so you see exactly what we found, not a vague summary from the parking lot.

  2. Tear-off or recover, decided honestly

    If the deck is sound and the assembly allows it, a single recover over the existing roof can save you money. If there is trapped moisture or failed insulation, we tear off to the deck. We tell you straight which one your building needs and why, the same honest call we make on a house.

  3. Repair the deck and insulation

    With the old roof open we replace wet or failed insulation and any soft decking, then set tapered insulation where you need positive drainage so water runs to the drains instead of ponding after a Missouri downpour.

  4. Install the membrane or metal system

    We install your chosen system, a Carlisle TPO membrane heat-welded at the seams, a TriBuilt low-slope assembly, or standing-seam metal, with all flashings, curbs, and edge metal detailed to the manufacturer's spec. The system is named on your written estimate before we order it.

  5. Clean to no footprint, on a working site

    We stage around your operating hours, keep the lot and walkways clear, magnet-sweep for fasteners, and haul every scrap. Our cleanup is the thing customers name most. We get in, do it, and get out without leaving a footprint on a business that has to open the next morning.

Local angle

Washington's commercial roofs take the river-valley load. The historic blocks downtown sit low near the water where wind off the channel hits the parapets and edge metal first, and the newer buildings spreading south toward the bypass take spring hail straight on. The federally declared March 2025 disaster swept large hail and straight-line winds over 75 mph across Franklin County and worked roofs across this whole town, and a Missouri winter of freeze-thaw then opens every seam that hail bruised. On a near-flat commercial deck that punishment shows up as ponding water and lifted membrane long before a homeowner would notice, which is why every Washington commercial job we quote starts with one of us walking the actual roof and Amy's drone footage, not a satellite image or a drive-by.

FAQ

Commercial Roofing in Washington: questions

We install three. Carlisle TPO membrane for flat and near-flat roofs on downtown storefronts, warehouses, and offices, TriBuilt low-slope and torch-down for low-pitch sections and additions, and standing-seam metal for pole barns, churches, and agricultural buildings around Washington. We work buildings up to four stories. The system is named on your written estimate before we order it.
Almost never. Our in-house family crews stage around your operating hours, keep the lot and walkways clear, and work in sections so a downtown storefront or an office along Highway 100 stays open. We give you the sequence and timeline in writing with the estimate, so you know which areas we are on and when, not a vague promise that wrecks your week.
It depends on slope and budget. Carlisle TPO is our standard for flat and low-slope roofs and costs less to install upfront, with a reflective white surface that cuts summer cooling load in the river valley. Standing-seam metal carries the longest service life we offer and is best against hail and the wind that comes off the Missouri River channel, at a higher upfront cost. We walk your roof and tell you straight which one fits.
If hail or wind caused the damage, often yes. Tom Emmendorfer documents the membrane damage, files the claim, and meets your Washington adjuster on the roof to walk them through every bruised seam and lifted flashing. You pay your deductible and we handle the claim. Under Missouri law no roofer can legally pay or waive a deductible, so be careful with anyone who offers to on a commercial job.
Often yes, and we will say so if it is the honest call. A traceable membrane puncture, a failed seam, or leaking edge metal on a Washington storefront is usually a repair, not a tear-off. If the deck is sound we can also recover over the existing roof to save you money. We only recommend full replacement when trapped moisture or failed insulation makes it the right call.
Yes. Tom Emmendorfer is based here and our second family office runs in Washington under the original Emmendorfer Roofing name, alongside our Union shop. The family has roofed Washington since 1990. Many companies showing up for commercial roofing here are St. Louis-metro operators with one landing page and no yard in Franklin County. Call (314) 568-4163 and a real Emmendorfer answers.
