Commercial Roof Replacement in Indianapolis

Full tear-off and replacement for flat and low-slope commercial buildings. TPO, EPDM, and modified bitumen systems installed with full documentation and a 5-year workmanship warranty.

When a commercial roof reaches the end of its serviceable life — or when damage is too extensive for repair — replacement is the right call. A properly installed replacement membrane protects your building for 20 or more years and eliminates the ongoing cost of repeated repairs that don't address the underlying condition.

Roofing Systems We Install

We install the three most common commercial flat and low-slope membrane systems:

  • TPO (Thermoplastic Polyolefin): A single-ply membrane welded at the seams, with strong resistance to UV, heat, and puncture. Well-suited to most commercial buildings in Indiana's climate.
  • EPDM (Ethylene Propylene Diene Monomer): A durable rubber membrane that performs well in temperature extremes. Long track record on flat commercial roofs.
  • Modified Bitumen: A multi-ply system that provides excellent impact resistance and is a good fit for buildings with rooftop equipment or heavy foot traffic.

Our Replacement Process

  1. Inspection and assessment: We walk the roof, check the deck and insulation condition, document existing damage, and identify any drainage or structural issues before writing a scope of work.
  2. Proposal: You receive a written proposal with a clear scope, specified materials, timeline, and price. No surprises.
  3. Permits: We pull required permits and handle coordination with your local building department.
  4. Tear-off and installation: The old membrane is removed down to the deck. We inspect the deck for soft spots or damage and address those before installing new insulation and membrane.
  5. Final documentation: You receive photos of the completed work, warranty documentation, and any required inspection sign-offs.

5-Year Workmanship Warranty

Every commercial roof replacement we complete is backed by a 5-year workmanship warranty. Manufacturer material warranties may also apply depending on the system specified.
