What Commercial Roofing Systems Do You Install?

We install and service the full range of commercial systems: TPO and EPDM single-ply membranes, modified bitumen, standing-seam metal, and roof coatings for restoration, matched to your building’s slope, use, budget, and goals.

TPO (thermoplastic single-ply)

The most common choice for new flat and low-slope roofs. Heat-welded seams, a reflective white surface that cuts summer cooling loads, and strong resistance to Iowa UV and temperature swings.

EPDM (rubber membrane)

The proven workhorse of flat roofing. Excellent in freeze-thaw cycles, straightforward to repair, and a decades-long track record on Midwest buildings.

Modified bitumen

Multi-ply asphalt-based protection with real puncture resistance; a fit for roofs with heavy foot traffic or rooftop equipment access.

Standing-seam metal

For sloped commercial, agricultural, and industrial buildings where longevity is the priority. Full details on our metal roofing page.

Roof coatings and restoration

When the existing membrane is aging but sound, a fluid-applied coating can add years of service life at a fraction of replacement cost. We’ll tell you honestly whether your roof is a coating candidate or past that point.

Not sure what’s in your building now, or what should be? That’s exactly what the free assessment answers.

What Commercial Roofing Services Do You Offer?

We handle the full commercial roof lifecycle: new construction installation, re-roofing and replacement, repairs, preventive maintenance programs, and emergency response, so one contractor is accountable for your roof from install through end of service life.

New construction. Coordinated with your GC and timeline, installed to manufacturer spec so the full warranty applies.
Re-roof / replacement. When your roof is beyond repair, we replace it, complete with a full plan for tear-off or recover, insulation upgrades, and code compliance.
Commercial roof repair. Membrane punctures, failed seams, flashing leaks, or ponding-related deterioration, diagnosed and fixed with photo documentation.
Preventive maintenance programs. Scheduled inspections, drain clearing, seam and flashing checks, and minor repairs before they become interior leaks. The cheapest commercial roofing you’ll ever buy is the maintenance that prevents replacement.
Emergency response. When hail or straight-line winds open your roof at 2 a.m., we stabilize first and document for insurance. See our storm damage restoration service.

What Types of Buildings Do You Serve?

We serve retail, office, warehouse and industrial, agricultural, and multifamily properties across DeWitt, Clinton County, and the Quad Cities corridor, from single storefronts to large low-slope industrial and agri buildings.

That includes strip retail and standalone stores, professional offices and clinics, warehouses and light industrial facilities, machine sheds and agri operation buildings, and apartment and multifamily residences.

Every building type has different roofing realities: a warehouse tolerates a straightforward TPO recover; a clinic needs low-odor, low-noise scheduling; an occupied apartment building needs tenant communication as much as flashing detail. We plan for the building you actually run, not a generic spec.

How Much Does a Commercial Roof Cost in DeWitt?

Commercial roofing cost is driven by square footage, the system installed, insulation and tear-off requirements, roof access, and the number of penetrations. This is why credible pricing starts with an on-roof assessment, not a phone estimate.

The main drivers, so you can budget intelligently:

Square footage. The baseline but not linearly, since mobilization and edge detail costs spread differently across large vs. small roofs.
System selection. TPO, EPDM, mod-bit, coating, or metal each carry different material and labor profiles.
Insulation and tear-off. Whether the existing roof can be recovered or must come off, and what code-required insulation adds.
Roof access. A single-story building with clear staging costs less to work on than a tight downtown roof requiring craning.
Penetrations. Every HVAC unit, vent, drain, and skylight is flashing detail work.

After the assessment you get a written scope and price, plus options where they genuinely exist (repair vs. coat vs. replace), with the trade-offs of each laid out. No pressure, no padded “insurance number.”

How Do You Minimize Business Disruption?

We schedule around your operations (including off-hours and phased work), maintain OSHA-aware safety practices on site, protect entrances and inventory, and run daily cleanup, so your business keeps running while the roof gets done.

In practice, that means:

Scheduling that fits your business, not ours. Phased sections for occupied buildings, off-peak hours for retail, coordination with tenants for multifamily.
Safety-first job sites. OSHA-aware crews, controlled staging areas, and clear communication about where work is happening each day.
Protection and cleanup. Entrances, landscaping, HVAC intakes, and parking protected; magnetic sweeps and debris removal daily.
Warranties in writing. Manufacturer system warranty (installed to spec so it actually applies) plus Wegner’s workmanship warranty. When you call about the roof in year six, it’s the same company and the same phone number.

Frequently Asked Questions About Commercial Roofing

What commercial roofing systems do you install?

TPO, EPDM, modified bitumen, standing-seam metal, and restoration coatings. We recommend based on your building’s slope, use, budget, and how long you need the roof to perform.

TPO vs. EPDM: which is better for Iowa?

Both perform well here. TPO’s reflective surface cuts summer cooling costs and its welded seams are highly watertight. EPDM has a longer Midwest track record and handles freeze-thaw cycles exceptionally well. The right choice depends on your building. The free assessment settles it.

How much does a commercial roof cost?

It depends on square footage, system, insulation and tear-off requirements, access, and penetrations. We provide a written scope and price after an on-roof assessment, with repair, coating, and replacement options compared where applicable.

Do you offer commercial roof maintenance programs?

Yes. Scheduled inspections, drain and seam checks, flashing review, and minor repairs, with photo documentation for your records. Preventive maintenance routinely extends membrane life and catches small failures before they become interior damage.

Do you provide emergency commercial roof repair?

Yes. For storm damage or sudden leaks, we respond quickly to stabilize the roof, prevent further interior damage, and document everything for your insurance claim. Call (563) 214-1558.
