An aging commercial flat roof in downtown Crowley showed every textbook sign of a system at the end of its life — ponding water across the field, blistered patches under satellite dishes weighed down with cinder blocks, and a worn modified-bitumen surface that had given everything it had. The retail tenant below couldn't close for a week. We solved both at once.

The Problem

The owner called us in after a small leak above the office turned into a wet ceiling tile. Our drone inspection showed a much bigger story: the field had multiple low spots holding water for 24+ hours after rain, the original flashings around penetrations had cracked and been patched with mastic, and the membrane itself was past its serviceable life. A repair would have been throwing good money after bad.

The Approach

We specified a full tear-off and replacement with a fully-adhered TPO system. Three things mattered:

  • Phasing. The retail tenant below didn't have the option to close. We split the roof into staged sections so the active workspace was always over an empty stockroom — never the sales floor.
  • Drainage correction. Tapered insulation re-pitched the low spots toward the drains instead of just laying new membrane over the same problem.
  • Detail work. Every penetration got new pre-molded flashing instead of field-fabricated patches. Every parapet got new edge metal with a continuous cleat.

The Result

The crew completed the project in six working days with zero operational hours lost for the tenant. The replacement is backed by a manufacturer NDL warranty plus our own workmanship warranty. The hero photo at the top of this article — the white TPO at sunset with the American flag flying — is the same roof, six days after the photos below.
