Commercial Roofer Near You
Your Building Deserves a Commercial Roofer Who Gets It Right
Commercial roofing isn’t residential roofing with a bigger ladder. It’s a different game—flat roofs, low slopes, drainage challenges, and building codes that don’t apply to homes. You need a team that understands the difference.
We’ve been handling commercial roofing projects across the Midwest since 1977. Office buildings, warehouses, retail centers, multi-family properties—we’ve done it all. And we bring the same inspection-led approach to every project.

One Call Takes Care Of It All
Inspection, estimate, installation, warranty, and maintenance—all from one team that understands commercial roofing.
TPO (Thermoplastic Polyolefin)
Energy-efficient, highly reflective, and heat-weldable seams. One of the most popular choices for commercial flat roofs due to its durability and cost-effectiveness.
EPDM (Rubber Roofing)
A time-tested single-ply membrane known for flexibility and weather resistance. Great for buildings with temperature swings and minimal foot traffic.
PVC (Polyvinyl Chloride)
Chemical-resistant and highly durable. Ideal for restaurants, industrial facilities, and buildings exposed to grease or chemicals.
Modified Bitumen (Mod Bit)
A multi-layer system that combines asphalt with reinforcing fabrics. Excellent for high-traffic roofs and areas with heavy equipment.
Built-Up Roofing (BUR)
The original flat roofing system—layers of asphalt and reinforcing fabric. Proven performance for large commercial buildings and warehouses.
Commercial Metal Roofing
Standing seam and metal panels for commercial applications. Long-lasting, low maintenance, and ideal for buildings with pitched or low-slope roofs.

What Commercial Roofing Systems Do We Install?
We specialize in flat and low-slope roofing systems designed for commercial buildings. Here are the systems we work with most:
Real Warranties
Our Inspection-Led Approach to Commercial Roofing
We don’t guess. We don’t assume. Every commercial roofing project starts with a thorough inspection using industry-leading diagnostic tools.
Core Samples
We extract small sections of your roof to examine each layer—membrane, insulation, and deck—to identify hidden damage and moisture infiltration.
Moisture Evaluation
Using infrared scanning and electronic detection, we map moisture trapped beneath the surface. This tells us whether repair is viable or replacement is necessary.
Ponding Analysis
We assess drainage patterns and identify areas where water pools. Ponding accelerates roof deterioration and must be addressed in any repair or replacement plan.
Tear-Off vs. Re-Roof
Tear-Off vs. Re-Roof: Which Does Your Building Need?
Not every commercial roof needs a full tear-off. Sometimes a re-roof (or re-cover) is the smarter, more cost-effective option. Here’s how we help you decide:
Full Tear-Off & Replacement Is Required
- Existing roof already has two or more layers
- Moisture is trapped in the insulation or deck
- Structural damage or deck deterioration is present
- Building codes require removal
- Current system is incompatible with new membrane
- Warranty requirements mandate full replacement
Re-Roof (Re-Cover) May Be Acceptable
- Only one layer of roofing currently exists
- No moisture damage in the deck or insulation
- Structural integrity is confirmed
- Local codes permit an additional layer
- Budget constraints require a phased approach
- Existing roof is compatible with new system

FAQs
Common Questions About Commercial Roofing
Commercial roofing typically involves flat or low-slope roofs using systems like TPO, EPDM, and PVC—while residential roofing usually means pitched roofs with shingles. Commercial projects also involve stricter codes, larger scales, and different drainage requirements. You need a commercial roofer who specializes in these systems.
Commercial roof replacement costs depend on the size of your roof, the system you choose, and the condition of the existing structure. Most projects range from $5 to $15 per square foot. We provide detailed written estimates after every inspection.
