MCA Offers New White Paper On Retrofitting With Metal Roofing

Chicago, IL - The Metal Construction Association (MCA) has released a new white paper, “Retrofitting Existing Roofing with Metal.” The document details the benefits of installing a new metal retrofit roof system over existing conventional roofs, with a focus on residential construction.

The versatility of retrofit metal roofing translates into many advantages, including cost-saving considerations like long service life, resilience, extended warranties and even energy savings. Along with these, metal retrofitting offers enhanced aesthetics, and avoiding the need to dispose of the existing roofing materials, an issue that annually contributes between nine and ten million tons of waste to landfills.

The paper continues with details of retrofit installation methods, including direct-to-deck installation, where the metal panels are installed directly over the existing roofing materials, over-purlin installation, where horizontal wood or metal zee or hat-shaped purlins are installed directly over the existing roofing materials, and above-sheathing ventilation, a common energy-saving strategy used when installing metal retrofit systems.

“With more and more people recognizing the myriad of benefits that retrofitting their existing roof provides, this paper is an absolute must-read. Retrofitting allows you to potentially transform the façade of your structure, and gain so many environmental and economic benefits,” says James Bush, MCA executive committee chair.
