Installing the Duro-Last system for your commercial or industrial property is a smart choice for many reasons:

We use Duro-Last’s custom fabrication of single-ply roofing systems that offer several benefits:

  • Duro-Last prefabrication eliminates up to 85% of on-site, rooftop membrane seaming, reducing the possibility of installation errors and potential leakage problems.
  • Prefabricated roofing systems are easier to install throughout the year, even during adverse weather conditions.
  •  The time required for installation is minimal so that the contractor can get on and off the job quickly.
  • The little amount of on-site membrane seaming is done with hot-air welding techniques, which are virtually unaffected by cold or damp weather conditions.
  • Single-ply roofing prefabrication minimizes waste, time, and money. 
  • The Duro-Last single-ply roofing system is durable, energy-efficient, installed with no disruptions, is code compliant, and is backed by the industry’s best warranties.
