In commercial and industrial (C&I) settings, roof-mounted solar photovoltaic (PV) systems come with a unique set of engineering challenges and technical risks. While some factors like structural analysis and roof loading apply broadly to all low-slope roofs, others—such as waterproofing details or slipsheet requirements—are specific to the type of roofing system in place.
This two-part article provides a high-level overview of the most important engineering and risk management considerations for C&I roof-mounted PV systems, as well as key insights into the most common types of C&I roofing. Proper identification of the roofing system is essential before installing a solar PV array, as it directly impacts design, installation, and long-term performance. This article focuses on roof system identification and condition assessment, which are critical steps in any solar project.
Understanding the type of roofing material is crucial because different membranes have varying coefficients of friction, which affect wind load calculations and ballast requirements. For example, single-ply membranes such as TPO, EPDM, and PVC each have distinct characteristics that influence how solar arrays are mounted and secured. Additionally, built-up and modified-bitumen roofs require careful evaluation of layer thickness and weight, while metal-panel roofs offer unique attachment options like standing seams.
Roof condition also plays a major role in the success of a solar project. Signs like alligatoring, water pooling, or other forms of deterioration can signal an aging roof that may not support a PV system. It’s vital to assess the remaining lifespan of the roof and ensure that any modifications don’t void existing warranties. Working with the original roofing contractor can help maintain warranty coverage and avoid disputes over leaks or damage.
By thoroughly evaluating the roofing system, solar installers can reduce risks, improve performance, and ensure a long-lasting, reliable solar power solution for commercial buildings.
