Commercial Roof Replacement in Louisiana

When is it time to replace a commercial roof?

A commercial roof should be replaced — not patched — when the membrane is past its service life, when the deck below is compromised, when leaks are systemic instead of localized, or when an insurance claim has documented storm damage beyond reasonable repair. Most TPO and PVC roofs in Louisiana hit replacement territory at 18-25 years. Modified bitumen tends to make it 25-30. Old built-up tar-and-gravel systems often last beyond 30 years but deliver diminishing performance in the back half.

If you're seeing widespread granule loss, brittle membrane, multiple seam failures, ponding water that wasn't there at install, or recurring leaks despite repairs, replacement is almost certainly the right call. Bayou Roofing offers free 32-point inspections to give you a written, no-pressure answer on repair vs. replace.

5. Final walk-through — Project manager walks the property with you, hands over warranty paperwork, registers your manufacturer warranty.

Replacement costs in Louisiana

Commercial roof replacement pricing varies by system:

• TPO / PVC single-ply: $5-$9 per sq ft installed
• Modified bitumen: $6-$10 per sq ft installed
• Standing-seam metal: $11-$18 per sq ft installed

A typical 20,000 sq ft commercial replacement falls in the $100K-$360K range depending on system. Tear-off vs. overlay, insulation R-value, deck repairs, and access all influence the final number. Every Bayou Roofing quote is line-itemed so you see exactly where every dollar goes.
