Humidity and Roofing Seams, What’s on your Roof?

  • Longevity of your roof system is directly affected by the climate it’s installed in, and the weakest point of any roof is it’s seams.

  • The reason for Duro-Last’s superior durability and longevity are the seams , which are hot air welded, and as a result are impervious to leaks throughout it’s life.

  • Welded seams are not affected by humidity whereas glued/fully adhered systems are susceptible to defects when installed in a high humidity environment.

Duro-Last eliminates the variable of humid weather installation with heat welded seams, and is ideal for Ohio valley roofing weather climates.

Roof Top Solar Panels

The growth of rooftop solar (or photo-voltaic – PV) systems has exploded over the past few years, helped by incentive programs, technological improvements, and the need for alternative energy sources because of rising costs. The Duro-Last roofing system is particularly effective for rack-mounted rooftop solar systems. It’s precision-fabricated to fit each building, and delivered to the job site with up to 85% of membrane seaming completed in our factory. Custom fabricated flashings for roof-penetrating support structures eliminate most rooftop labor from these critical areas. Pre-made rack flashing can mean a faster roofing system installation as well. Call Us For More Info (513) 923-1818
