MCA conducts many technical studies and research projects in partnership with member and industry partners. These studies include bulletins, white papers, manuals and reports that ensure that metal is at the forefront of innovation, and proactive with codes and standards.
Most standing seam panel installations require the use of specific fastening techniques to allow for thermal expansion and contraction while also safeguarding against attachment fatigue. This document focuses on clip-attached style standing seam roof systems, and addresses specific details and concerns for proper selection and use of the connection that anchors the roof panel to the roof panel support element.

This white paper, written by Brian Gardiner of BMG Enterprises, LLC, compares two commonly used methods of retrofitting exiting metal roofs, single-ply systems and metal panels, and illustrates important design considerations that apply. The design consideration include the existing support structure, secondary framing deflection, the existing metal roof properties, drainage, roof fastening, drag load, and fire rating. The paper also contains a brief review of the building code requirement.
This document describes best practices for the selection and installation of curbs used specifically on low slope (less than 2:12), coated-steel or aluminum roof systems. Steep slope or architectural roofing is not addressed in this document. Different design considerations for curbs are required for steep slope roofing and for materials other than coated steel or aluminum.
This must-read article from Florida Roofing Magazine will enlighten on the benefits of Roof Coatings.
This manual addresses the installation of metal roofing material and related accessories and includes information pertaining to both new construction reroofing and retrofit projects.

This Technical Bulletin is intended to serve as a guide for the application of spray polyurethane foam insulation (SPF) used in metal panel assemblies. Single skin metal walls and roofs are durable and sustainable components of a building envelope system, however the cladding offers no inherent insulation value to the building. To improve the energy efficiency of buildings, insulation, air barriers and vapor retarders are commonly used.
This Technical Bulletin provides guidance when working with different metals used in roofing installations. Most metals used for construction projects are chosen for their strength, corrosion resistance and longevity. However, some metals do not perform well when placed in contact with specific other metals or exposed to certain chemical compounds. Users should be aware of compatibility issues and situations that may affect the performance of the installed roof.
The purpose of this guide is to familiarize personnel with the general knowledge, basic operation, safety, and maintenance procedures followed by standard troubleshooting suggestions for standard roof seaming processes. This is a general guide to be used in conjunction with the material installation guide and the project's erection drawings.
Metal roofs have long been considered a product of choice for snow areas because of their superior response and tolerance to many of the characteristics of these environments. This technical bulletin will provide the designer with the information required to make a prudent and informed decision through awareness of some general design parameters and snowmelt phenomena.
This seven-part series written by Rob Haddock, president of the Metal Roof Advisory Group, Ltd., offers essential, detailed information on metal roofing including the history and material types, appropriate coatings and paint systems, induced finishes, profiles and profiling equipment, metal panel attachment, and the mounting of rooftop equipment.
General procedures for identifying a modular panel metal roof, accessing or ventilating a stone-coated metal roof, and ventilating attic fires.
Static and dynamic analyses of metal roof systems using Finite Element Method indicate that Finite Element Analysis is an appropriate tool for the product development of metal roof structures.
It is common for an existing building to be serviceable in every way; however, some roof repairs may be required. On many occasions, MCA has been asked what types of roof repair materials are required and what code supporting language exists. MCA investigated this issue and found direction offered within the Existing Building Code.
When a metal roof is employed on a project, it seems to heighten people’s awareness of lightning and some question whether or not the use of metallic roofing increases the risk of lightning strike. Metal roofing does not in any way increase this risk.
This report documents and summarizes the work conducted to determine with reasonable certainty the roof service life that can be expected of a “like-in-kind”, low-slope 55% Al-Zn alloy-coated steel Standing Seam Roof (SSR) system when installed today in a like environment using best practices. It incorporates the results of multiple field inspections, independent laboratory analyses of metallic corrosion of roof panels, components and sealants, and includes assessment of all integral ancillary components that impact the end of roof service life.
