How is a Duro-Last roof repaired?

A Duro-Last roof will last approximately 25-30 years. With a Duro-Last system, repairs by a professional roofing company can be quite simple and just take 1 day’s time and bring your roof’s integrity back.

Building owners will first notice they need a Duro-Last roof repair when the water is entering the building. This usually happens when the seams come loose and need to be re-welded or the membrane is punctured. Once the water moves past the membrane it will enter the roofing insulation and over time will enter your roof deck and eventually start to leak inside your building.

At this stage, it’s time to call a commercial roofing contractor to perform a roofing inspection. A roofing inspection with our professional roofing contractors will identify the following:

  • The area of where the leak is
  • Current age of the roof
  • Current layers of the roof
  • Condition of the Seams
