Signs It’s Time for a Permanent Solution

Royalty Roofing specializes in commercial flat roof replacement, with a primary focus on high-performance PVC single-ply roofing systems.

While we replace all major flat roofing types — including TPO, EPDM, modified bitumen, and built-up roofing — our expertise is in delivering long-term performance through professionally installed PVC single-ply systems.

Flat roof replacement isn’t just about removing old materials. It’s about upgrading your building to a modern, energy-efficient system that reduces maintenance, resists ponding water, and protects your investment for decades.

For many facilities, upgrading to a PVC single-ply system during replacement offers superior durability, chemical resistance, and long-term cost savings compared to traditional flat roofing systems.

Signs Your Flat Roof May Need Replacement

Flat roofs often show warning signs before failure. If you’re seeing any of the following, it may be time to consider a full flat roof replacement:

Recurring leaks despite multiple repairs
Standing or ponding water
Cracked or shrinking membrane
Seam separation
Blistering or surface breakdown
Wet or saturated insulation
Roof age approaching 20+ years

Many older flat roofs were installed using systems that are no longer the most efficient or durable options available today. Replacing them with a modern PVC single-ply system can significantly improve longevity and performance.

For commercial customers who have single locations or who own or manage multiple facilities, and are looking for commercial roofing companies near me, Royalty provides roofing services across the continental United States from our Seymour, Indiana, headquarters or another of our strategically located offices.

Flat Roofing Systems We Replace & Install

Royalty Roofing replaces and installs all major commercial flat roofing systems, including PVC Single-Ply Roofing, TPO Roofing Systems, EPDM Roofing Systems, Modified Bitumen and Built-Up Roofing (BUR).

However, we specialize in PVC single-ply flat roofs, particularly Duro-Last® systems, due to their long-term performance advantages.

Why PVC Single-Ply Roofing?

PVC membranes offer:

Heat-welded seams that create a watertight bond
Excellent resistance to ponding water
Superior chemical and grease resistance
High reflectivity for energy efficiency
Long service life with minimal maintenance
