Commercial Roofing FAQ

Commercial roofing decisions often come with complex questions about repairs, replacement, materials, and long‑term performance. This Commercial Roofing FAQ is designed to help property owners and facility managers better understand common roofing issues, options, and planning considerations. The answers below provide clear, practical information to support informed decision‑making for commercial roofing systems.

  • What types of commercial roofing do you work on?

    We focus on commercial low slope and flat roofing systems commonly used on commercial and industrial buildings. Our work includes flat membrane systems (including TPO, EPDM, and PVC), roof repairs, replacement/installation, coatings, and maintenance services. 

  • Do you handle active leaks and urgent commercial roof repairs?

    Yes. We perform commercial roof repairs for active leaks, storm damage, and localized failures that can disrupt building operations if left unresolved. Our repair approach focuses on accurate diagnosis and durable corrective solutions.

  • How do you decide between repair, coating, and full replacement?

    We start by stabilizing active problems, then evaluate whether the roof is a candidate for ongoing repair/maintenance, a coating system, or full replacement. When roof conditions exceed coating limitations, replacement may be required; coatings are often most effective when paired with maintenance planning.

  • What’s included in a commercial roof repair?

    Commercial roof repair typically includes leak investigation and corrective repair of the true failure point—common issues include seam failures, flashing damage, penetrations, fastener issues, membrane punctures, and storm impacts. The goal is to stop intrusion, stabilize the system, and clarify next steps for planning.

  • Do you repair both flat roofs and metal roofs?

    Yes. We repair flat, low slope, and metal roofing systems, using compatible materials and proven techniques to restore performance without unnecessary full replacement. 

  • What commercial flat roofing systems do you install?

    We install and service commercial flat roofing systems using single ply membranes such as TPO, EPDM, and PVC, selected to withstand weather exposure, rooftop traffic, and day to day demands on commercial properties.

  • Are you manufacturer-authorized for commercial roofing systems?

    Yes. We are an authorized applicator for multiple commercial roofing manufacturers (including Carlisle, Mule Hide, Derbigum, and CertainTeed) and install systems designed to meet performance and warranty standards.

  • How do you choose between TPO, EPDM, and PVC?

    Selection depends on the building’s layout, drainage conditions, operational requirements, and expected rooftop exposure/traffic. We evaluate system needs as part of the overall roof design so the membrane performs as a complete commercial roof system.

  • Can you address drainage issues and ponding risk on flat roofs?

    Yes. Flat roofing systems are designed around the building’s slope and drainage conditions so the roof performs long-term. We tailor system design to the roof layout, insulation needs, and rooftop equipment conditions.

  • Do you provide commercial roof replacement and new installation?

    Yes. When repairs are no longer enough, we provide commercial roof replacement and installation for existing buildings and new construction/additions, including reroofing, tear offs, recover systems, and new roof installs.

  • Do you install commercial metal roofing?

    Yes. We install and service commercial metal roofing systems (including standing seam and exposed fastener systems), tailored to the building structure, slope, and operational requirements.

  • What is a metal roof retrofit system?

    A metal roof retrofit is an option for qualifying buildings where the existing metal roof structure remains sound. Retrofit systems can involve installing flute fillers over existing panels, adding insulation, and installing a new single ply membrane such as TPO—often reducing disruption compared with full tear off when conditions permit.

  • When is a commercial roof coating appropriate?

    Coatings are used to extend roof life and improve performance when conditions allow, creating a seamless watertight barrier that helps protect qualified flat and metal roofing systems from weather exposure and moisture intrusion. If roof conditions exceed coating limitations, replacement may be required. 

  • What warranty terms are typical for commercial roof coatings?

    Warranty options for coating systems typically range from 5 to 15 years, depending on roof condition, material type, and the specific coating system.

  • What does a commercial roof maintenance program include?

    Commercial roof maintenance focuses on inspecting critical components, addressing minor deficiencies, and supporting long term planning for flat, low slope, and metal roofing systems. Regular maintenance helps catch issues at seams, flashings, penetrations, and drainage areas before they escalate.

  • Can maintenance support manufacturer warranty requirements?

    Yes—ongoing maintenance can support roof performance over time and may help with compliance related to manufacturer warranty requirements when applicable.
