Complete Roof Replacement

Commercial Roof Tear-Off & Replacement

Full removal of existing roofing systems and installation of high-performance replacements across South Texas — school districts, hospitals, industrial facilities, and more.

Complete roof tear-off and replacement is the most comprehensive roofing service American Contracting USA provides — and the one we have the deepest track record delivering across the Rio Grande Valley since 1948. When a commercial roof has reached the end of its useful life, overlay or restoration is not always viable. A full tear-off gives facility managers a clean start: complete removal of all failed roofing layers, thorough inspection and repair of the roof deck and substrate, and installation of a new high-performance system backed by a manufacturer warranty.

Our teams have executed full roof replacements on some of the largest and most complex facilities in South Texas — from 35,000 SF elementary schools to 120,000 SF multi-building CISD complexes and 80,000 SF industrial warehouses. We understand the operational constraints of occupied facilities: school buildings that cannot shut down, hospitals running 24/7, manufacturing plants with continuous production schedules. Every project is phased and scheduled to minimize disruption.

What's Included

  • Complete removal of all existing roofing layers — membrane, insulation, and cover board
  • Deck inspection, moisture testing, and structural repair before new installation
  • Insulation upgrade to current energy code requirements (R-25 and above)
  • Installation of new membrane system: TPO, EPDM, PVC, modified bitumen, or BUR
  • Standing seam metal on sloped sections and canopies
  • Heat-welded seams on single-ply systems for superior watertight performance
  • Manufacturer inspection and NDL warranty activation at project closeout
  • Full OSHA safety compliance and documented project management throughout

Why Full Tear-Off vs. Overlay?

A roof overlay — installing a new membrane over the existing system — can be tempting because it appears faster and less expensive. However, overlay is not always appropriate. Building codes in Texas limit the number of roof layers allowed. Wet or damaged insulation beneath the existing membrane traps moisture, accelerating deterioration of the new system. And most manufacturer NDL warranties require a full tear-off to be activated. Our roofing assessments always evaluate whether tear-off or restoration is the right choice for each facility.
