Scope of Work (Typical EPDM Replacement)

Roof Build-Up

  • Tear-off/recover; deck repairs as needed
  • Self-adhesive vapor barrier (as required)
  • Tapered polyiso insulation design
  • HD gypsum/polyiso cover board set in foam/adhesive

Membrane & Flashings

  • 45/60/75/90 mil EPDM, black or white
  • Taped seams with primer; factory corners/boots

EPDM Roofing — FAQs

Black vs white EPDM — which should I choose?

Black EPDM is the most common and highly UV-resistant; white EPDM improves reflectivity and may lower cooling loads. We’ll recommend the best fit for your building’s use and climate.

Ballasted vs fully adhered — what’s the difference?

Ballasted uses stone to weigh the membrane—often lower cost but adds structural load. Fully adhered uses adhesive—clean look, low flutter, great at perimeters and complex roofs.

Can you overlay EPDM over my old roof?

Often—if moisture is low, the deck is sound, and code allows. We evaluate with cores/moisture scans and may add a separator/cover board for compatibility and durability.

How long does an EPDM roof last?

Properly designed EPDM systems commonly deliver 20–30+ years, especially with HD cover boards, tapered insulation, and a preventative maintenance plan.
