Why TPO restoration was the right call for this campus

Institutional buildings like Manteca High School live and die by roof reflectivity. A bright white TPO surface rejects 80–90% of solar radiation versus 5–15% on a weathered dark membrane. On a campus this size, that swing translates to real money on the district’s HVAC bill every August and September — cooler classrooms, cooler portables, and a measurably cooler Buffalo Territory sports facility.

The existing TPO was structurally sound but had lost its reflective layer and was beginning to chalk. A full tear-off would have meant tarps over occupied classrooms, multi-week scheduling around the academic calendar, and a much higher line-item on the district budget. A coating restoration restores the white reflective surface, re-welds aging seams, and gets the campus back to a 15–20 year service life — without ripping anything off.

Scope across the campus

  • Main classroom buildings — primary instruction wings with the heaviest HVAC load.
  • Portable classrooms — each portable received the same prep, primer, and two-coat TPO system as the main buildings.
  • Buffalo Territory sports facility — large-span roof over the campus athletic facility, finished and documented separately.

Our process

  1. Prep — full pressure wash, debris removal, and inspection of every seam, drain, and penetration.
  2. Prime — manufacturer-spec primer to bond the restoration coating to the existing TPO substrate.
  3. Coat — two coats of TPO restoration coating applied per spec, with documented mil thickness.
  4. Weld & flash — heat-welded seam reinforcement, drain bowls re-flashed, every pipe and curb detailed.
  5. Document — written closeout with photos of every building section, warranty paperwork, and a maintenance schedule the district can hand to facilities.

Expected service life

A correctly installed TPO coating restoration on a sound substrate returns 15–20 years of additional service life — for roughly 30–50% of the cost of a full tear-off and replacement. For an active school campus, that’s a budget win and a scheduling win.
