When to replace

Signs you need flat roof replacement in Las Vegas

  • Standing water (ponding) that lingers more than 48 hours after rain
  • Blisters, bubbles, or splits in the membrane
  • Seams or flashing lifting, cracking, or pulling apart
  • Interior water stains, drips, or a sagging deck
  • The membrane is brittle, cracked, or shrinking with age
  • Repeated patch repairs that no longer hold
Decision

Repair or replace in Las Vegas?

Spot repairs and recoating can buy years on a flat roof, but once the membrane is widely failing or the deck below has gotten wet, full replacement is the durable fix.

Repair if…

  • Leaks trace to isolated seams, flashing, or a single puncture
  • The membrane is under ~15 years old and otherwise sound
  • A reflective recoat can extend the existing membrane's life

Replace if…

  • The membrane is brittle, blistered, or splitting across the roof
  • Chronic ponding has saturated the insulation or decking
  • The roof is past 20 years and leaking in multiple spots
