Bob Harvey Roofing • March 8, 2022

Do you want to know more about commercial Duro-Last roofing? Maybe you have a new building that needs roofing or need roofing options for an upgrading project? As an authorized Duro-Last contractor, Bob Harvey Roofing can answer all your questions.   


But what is commercial Duro-Last roofing? Duro-Last is a single-ply thermoplastic PVC membrane roofing system ideal for low-sloped or flat roofs. This type of roof is generally used for hospitals, schools, restaurants, worship centers, churches, industrial buildings, warehouses, retail and mixed-use buildings. It can also be used for residential buildings. 


Duro-Last has a track record in North America of more than forty years, and during this time, the product was adapted to the unique weather conditions of the region. The company is passionate about technical excellence and continuing education. That is why they participate in all major technical committees of key organizations within the industry. And offer continuing education through the following organizations:


  • The American Institute of Architects (AIA)
  • Green Business Certification Inc (GBCI)
  • International Institute of Building Enclosure Consultants (IIBEC).


Duro-Last Roofing 


What makes commercial Duro-Last roofing distinctive is its use of a high-quality reinforcement scrim inserted between two layers of PVC. The scrim gives Duro-Last membranes strength and puncture resistance. Knitted in-house, the threads-per-inch density of the scrim is among the highest in the industry. 


Adding to its durability and performance, the Duro-Last reinforcement scrim uses a third tie yarn to prevent runs and stop tears from spreading. The above-scrim membrane thickness also provides additional protection to the most exposed part of the roof. 


Quality control is crucial with the manufacturing of Duro-Last roofing. That is why the company provides a complete roofing system that includes deck sheets, parapet walls, penetrations, edge details and fasteners. Only authorized roofing contractors can install Duro-Last roofing systems. Duro-Last roofing systems can be mechanically attached, adhered, or induction welded using the Duro-Bond® system. 


Standard and
custom-fabricated Duro-Last roofing systems are available. The custom-fabricated roofing system allows up to eighty-five per cent of the seams to be factory completed. It dramatically reduces the potential for leaks, installation is quicker, and maintenance less. 


White is the standard Duro-Last color but is also available gray, dark gray, tan and terra cotta. There is also a series with a ballast or shingle design printed directly onto the membrane. Duro-Last membranes are available in various thicknesses and roll widths.


Regarding sustainability, Duro-Last has a take-back program that allows mechanically attached PVC roofs to be returned for recycling at the end of their useful life. It is then reprocessed into other products. Duro-Last also has solutions for rack-mounted commercial
rooftop solar applications.


Proven Performance 


In the more than forty years commercial Duro-Last roofing have been used on buildings, its performance is proven. It is why Duro-Last offers a 15-year No Dollar Limit (NDL) Supreme Warranty. This warranty is transferable, has no exclusions for ponding water and offer coverage against consequential damages. Other warranties are also available. 


Certifications and classifications for the Duro-Last sixty-millimeter membrane include:


  • Type III, American Society for Testing and Materials (ASTM) D4434 classification.


  • ENERGY STAR® qualified product: white color.


  • National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) 347 platinum-certified: white color.


  • One credit in U.S. Green Building Council Leadership in Energy and Environmental Design (LEED). Or Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) program: white color. 


Duro-Last solutions are 100% resistant to the typical roof damaging elements


Roof damage is typically caused by the elements such as the weather or individuals and companies performing non-roofing related maintenance. Commercial Duro-Last roofing membranes have the following characteristics that make them resistant to typical roof damaging elements:


  • Durable
  • Wind resistant
  • Fire resistant
  • Puncture resistant
  • Repairable and weldable 
  • Energy efficient 
  • Highly reflective, up to eighty-eight per cent.

Introduction Utah homeowners know that the state’s weather doesn’t play fair—scorching summers, heavy snowfall, sudden spring downpours. But what many don’t realize is how all that weather quietly takes a toll on one crucial system: your roof drainage. And when that system fails? It’s not just about clogged gutters—it’s about thousands of dollars in hidden damage to your roof, walls, foundation, and even your health. Roof drainage problems in Utah are more common than you might think, especially in older homes or those with flat or low-slope roofs. From standing water that rots decking and forms ice dams, to overflowing gutters that erode your landscaping and crack your foundation, poor drainage can destroy your home from the top down. In this article, we’ll break down the signs of drainage failure, the specific risks Utah homes face, and how to protect your biggest investment. You’ll learn what causes drainage issues, how to spot early warning signs, and the smart, affordable upgrades that can save you from costly repairs. What Is Roof Drainage? And Why Utah Homes Need It Working Right When most Utah homeowners think about roof maintenance, they picture shingles, flashing, or maybe even attic insulation. But one of the most overlooked systems—yet arguably one of the most critical—is your roof drainage. Without it, all the snowmelt, rain, and runoff from Utah’s wild weather has nowhere to go… except into your home’s structure. A roof drainage system is designed to move water efficiently off the roof and away from your home. It includes: - Gutters and downspouts - Roof pitch or slope - Flashing and drip edges - Downspout extensions or underground drainage pipes The goal is to prevent water from pooling on your roof, running behind siding, or collecting around your foundation. In Utah’s climate, that’s no small task. You’re dealing with ice dams in January, thunderstorms in July, and even snowstorms in April. Many older homes along the Wasatch Front—including Roy, Bountiful, and Ogden—were built with minimal or outdated drainage systems. If your home can’t shed water properly, you’re at serious risk of roof leaks, wood rot, and even structural damage. Quick Takeaways - Roof drainage problems in Utah are a leading cause of hidden home damage. - Signs include overflowing gutters, stained siding, and attic mold. - Common causes: clogged gutters, flat roofs, and poor attic ventilation. - Drainage issues can lead to foundation cracks, energy loss, and mold. - Preventative steps include gutter guards, downspout extensions, and insulation upgrades. - Bob Harvey Roofing provides expert inspections and drainage solutions across Utah. Conclusion Utah’s dramatic climate makes roof drainage a critical part of your home’s defense system. As we've explored, roof drainage problems in Utah can quietly lead to serious damage: rotting roof decking, mold in your attic, cracked foundations, and escalating energy bills. The good news? Most drainage issues are completely preventable. Whether it's cleaning your gutters, adjusting your downspouts, or upgrading insulation, small fixes can prevent big problems. At Bob Harvey Roofing, we know how to build and repair systems that handle Utah's extreme conditions—from ice dams to monsoons. We don’t just fix damage—we help you prevent it. Don’t wait until you see water stains. Book your roof drainage inspection today. FAQs 1. What causes roof drainage problems in Utah homes? Utah drainage issues often result from clogged gutters, poorly sloped roofs, or short downspouts. Snowmelt and monsoons can easily overwhelm these systems. 2. How do I know if my gutters are affecting my foundation? Look for water pooling near the base of your home, musty basements, or cracks in concrete walls. 3. Are ice dams a sign of roof drainage failure? Yes. Ice dams prevent water from flowing off your roof. This causes leaks, rot, and long-term damage. 4. Can poor roof drainage increase my energy bills? Absolutely. Moisture from drainage issues can ruin your insulation, forcing your HVAC system to work harder. 5. How often should I clean my gutters in Utah? At least twice a year—spring and fall. More often if you live near trees. 6. What are the best gutter options for Utah weather? Seamless gutters with guards are ideal for handling snow, rain, and debris. 7. Is roof drainage repair covered by homeowners insurance in Utah? It depends. Sudden damage is usually covered. Neglected maintenance is not. 8. When should I call a roofing contractor about drainage issues? Call if you see overflowing gutters, staining, or interior moisture. A professional inspection can catch problems early.
