FAQs

Duro-Last® Roofing Systems can be installed over many existing roofs, as long as the current roof remains structurally sound, appropriate underlayments are used when needed, and local building codes permit it. Contact Frontier Contractors to arrange a roof evaluation and find out if your roof is suitable for an overlay.

Incorporating roof washing into your routine maintenance plan can help maintain the appearance of your roofing system as well as solar reflectivity on white membranes. Utilizing Wash Safe Roof Wash from Duro-Last® can keep your rooftop free of biological growth, and a non-sudsing, non-abrasive cleanser such as Spic and Span® or Simple Green® can keep your rooftop clean of dirt and environmental debris. Solvent-based cleaners cannot be used. For more information, view the Duro-Last Care and Maintenance Guide and contact Frontier Contractors to learn more about cleaning and maintaining your Duro-Last Roofing System.

While Duro-Last® Roofing Systems are designed to withstand the elements and provide long-term protection, general routine maintenance goes a long way in protecting your overall investment. In addition to regular inspections by a roofing professional, as well as any inspections required with your Duro-Last® Warranty, owners should plan to check their roof at least twice per year for potential damage and regular clean-up. Download the Duro-Last Roofing System Care and Maintenance Guide & Owner Checklist for detailed information and checklists to help guide the care of your roofing investment.

While intended for flat and low-slope applications, Duro-Last® Roofing Systems can be installed on any roofing surface with proper design.

Roofing costs vary depending on the condition of the structure and the materials selected. Installing a roof on new construction differs significantly from re-roofing an existing building that requires a full tear-off. For a detailed estimate, contact us at 412-927-1104.

Left unaddressed, roof leaks can escalate into more severe issues. If you detect a leak in your Duro-Last® Roofing System and it’s still under warranty, reach out to the Frontier Contractors Warranty Department at 412-927-1104.
