Commercial roofing in Sullivan is a different animal than a house roof, and the flat or low-slope membrane over a Sullivan business fails in ways a steep shingle roof never does. A storefront near the downtown Springfield Road corridor, a shop along Service Road by the I-44 interchange, a church off Highway 185, or a warehouse out toward the industrial ground near the airport all carry a near-flat plane that has to shed water sideways instead of down. When that membrane bruises or a seam lifts, the leak does not drip into a living room. It shows up over your inventory, your registers, or your equipment, and a business that has to open the next morning cannot wait.

Sullivan also sits in the path of the same storms that put us on rooftops all over this region. The federally declared March 2025 disaster hit Franklin County with large hail and straight-line winds over 75 mph, and Sullivan sat right in the teeth of it. Hail that size does not just dent metal, it bruises a TPO membrane and knocks years off its life. Emmendorfer Exteriors has roofed this part of Missouri since 1990 and based the business in Union, Franklin County since about 2003, twenty minutes up Interstate 44 from Sullivan. Founder Matt Emmendorfer built it from the side of a full-time job, then brought on sons Tom and Tim, and the family has put roofs on right around 2,400 Missouri homes and buildings, including 306 jobs in 2025. When a Sullivan business owner needs the work done over a running operation, the same family that answers the phone is the crew on the roof, not a subcontracted storm chaser working the I-44 corridor by the week.

How it works

What our commercial roofing includes in Sullivan

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

Sullivan straddles the Franklin and Crawford county line right on I-44, which means a commercial building here takes the full eastern-Missouri weather load with no shelter from it. The large hail that came through here in the March 2025 storms is the kind that ruins a flat roof quietly. It pocks the membrane and bruises the seams without punching an obvious hole, so the building keeps running for a year while water tracks under the membrane and rots the insulation underneath. Then the Missouri freeze-thaw winter expands and contracts everything until a bruised seam finally splits. We walk the entire membrane up close, document every soft spot and ponding pan with photos and drone footage, and on a storm claim Tom Emmendorfer meets your adjuster on the Sullivan roof and walks them through every bruised seam and lifted flashing, because that documented inspection is your one shot to get the full damage scope on the record before the adjuster forms their own view.

FAQ

Commercial Roofing in Sullivan: questions

Three main systems. Carlisle TPO membrane for flat and near-flat roofs on Sullivan storefronts, shops, offices, and warehouses, TriBuilt low-slope and torch-down for low-pitch sections and additions, and standing-seam metal for churches, pole barns, and agricultural buildings. We work buildings up to four stories. We walk your actual Sullivan roof and name the system in writing before we order anything.
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 on a Sullivan summer. Standing-seam metal carries the longest service life we offer and stands up best to the hail this part of I-44 sees, at a higher upfront cost. We get on your roof and tell you straight which one fits.
Yes. The federally declared March 2025 disaster brought large hail and damaging winds straight through Sullivan. On a flat commercial roof that hail bruises the TPO membrane and the seams without leaving an obvious hole, so the damage hides for a year while water gets under the membrane. If your Sullivan building has not been inspected since then, a free look is worth it before the bruising turns into a leak over your inventory.
Almost never. Our in-house crews stage around your operating hours, keep the lot and walkways clear, and work in sections so a Sullivan storefront, shop, or warehouse stays open. We give you the sequence and timeline in writing with the estimate, so you know which part of the roof we are on and when, not a vague promise that disrupts your week.
If hail or wind caused it, often yes. Tom Emmendorfer documents the membrane damage, files the claim, and meets your adjuster on the Sullivan roof to walk them through every bruised seam and lifted flashing. You pay your deductible and we handle the claim. 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.
Genuinely local. Our shop is in Union, a straight twenty-minute run down I-44 from Sullivan, and we have roofed this part of Missouri since 1990. Sullivan is a regular service town for us, not a name on a landing page. The same in-house family crew that answers the phone is on your roof, and on a leak or fresh storm damage we aim to be out the same day to look. Call (314) 568-4163.
