Why Choose Specialized Commercial Roofing?
Protecting Your Investment
Have you ever considered what goes into installing a dependable roof? We’ve been answering that question for decades.
When it comes to protecting your business, facility, or school, your roof is one of the most critical investments you’ll make. But not all roofing companies are equipped to handle the unique challenges of commercial roofing. That’s why working with specialists—not generalists—makes all the difference.
At Holthaus Roofing, we focus exclusively on roofing and have deep expertise in commercial and institutional buildings. From low-slope and flat roofing solutions to storm damage recovery and proactive maintenance, our specialized approach helps you avoid costly mistakes and ensure long-term performance.
Why is specialization so important?
Specialization means higher-quality work, long-term cost savings, and a smoother project experience. At Holthaus Roofing, we don’t just install roofs—we help businesses and schools protect their investments, minimize risk, and plan for the future.

The Right Materials & Systems for Your Building
Not all roofing materials are created equal. A system designed for a residential home won’t work for a school, hospital, or warehouse.
✔ We install and maintain TPO, EPDM, Duro-Last, and metal roofing systems—solutions designed for commercial durability.
✔ Our certifications with manufacturers like Duro-Last mean you get industry-leading warranties and expert installation.
Specialized Crews = Fewer Issues & Faster Completion
A roofer that mainly does residential work may not be familiar with the complexity of large-scale commercial projects. That can lead to delays, budget overruns, or improper installations.
✔ Our teams are trained specifically for commercial roofing, allowing us to work efficiently, reduce disruptions, and complete jobs on time.
✔ We understand the logistics of working around business operations and school schedules, ensuring minimal disruption.


Preventative Maintenance That Extends Roof Life
Unlike a home, your facility’s roof is a long-term business asset. Ignoring maintenance leads to unexpected leaks, structural damage, and expensive replacements.
✔ We provide custom maintenance plans to detect small issues before they become major expenses.
✔ Regular inspections, sealant checks, and debris removal can add years to your roof’s lifespan.
