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.
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.
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.
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.
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 white paper is published to clarify to the architectural and design community the key principles and background information employed in Drained / Back Ventilated or Pressure Equalized Rain Screen wall systems. It is also available as a resource to the General Contractor, Code Official or Owner communities to explain how the design properties of these two systems accomplish water infiltration management and prevention.
Metal composite material manufacturers typically provide two types of core products: standard and fire retardant. The Metal Construction Association’s MCM Fabricator Council has developed this paper to clarify the allowable uses for standard and fire retardant MCM in accordance with the 2006-2012 editions of the International Building Code.
Though building and fire codes primarily address structural and fire performance of MCM cladding materials, other performance indicators often are used in the construction industry to define an acceptable application. This document defines the unified position of the Metal Construction Association (MCA) and its members with regards to visual acceptance parameters.
Insulated metal panels (IMPs) are one of only a few types of building products that can provide an entire building enclosure in one prefabricated product. However, despite their use for several decades in North America, there remains confusion about how IMPs manage rain water penetration, control air leakage, and act as continuous insulation.
IMP panels are required to be tested in accordance with NFPA 285 and specific IMPs have been tested and meet the conditions of acceptance of NFPA 285. Since every variation of a wall system cannot be tested,if the “basic” IMP panel system meets NFPA 285, minor variations in items can be allowed without retesting or an analysis.
Insulated metal panels offer benefits for the entire building team. When you consider insulated metal panel products, use the information presented herein as a start to properly promote, specify and detail a project. Additional information is available from the specific manufacturers. Contact the MCA for a list of member manufacturers.
Environmental Product Declarations provide LCA-based information and details about the products’ environmental aspects and assist purchasers and users in making informed comparisons between products. This industry Insulated Metal Panel EPD contains valuable information about product definition, building physics, the basic material and its origin, product manufacture and processing, in-use conditions, life cycle assessment results, and testing results and verifications.
Profiled metal roof or wall panels rely upon mechanical fasteners to secure the components to a structure. It is very important to select the correct type of fastener for metal construction in order to ensure a strong and weather-tight attachment. This Technical Bulletin serves as a guide for the selection of exposed fasteners used with metal roof and wall panels.
The use of copper-containing preservative-treated lumber in direct contact with certain metal products could lead to accelerated corrosion and affect the long-term integrity and performance of a metal roof or wall system. The most effective way to avoid corrosion is to ensure that the treated lumber used is either manufactured using the newer metal-free preservatives, micronized copper treatment or that there is a separation between the metal roof or wall panel and the preservative treated wood with some type of barrier material.
This technical bulletin is intended to be a guide to proper fastening of metal panels to wood or metal frame buildings. The selection of the proper tools for the fastening of metal roofing panels is critical for ease of installation, proper watertight sealing of the building, and the integrity of the connection.
Many uncontrollable factors contribute to oil-canning and no panel manufacturer, fabricator, or installer can assure the total prevention of oil canning on any given project. With careful attention to the production, material selection, panel design, and installation practice, the tendency for oil canning can be minimized.
Metal roof and wall panels are made with the highest recycled content from the most recyclable materials on earth, making them a great choice not only for today, but also for future generations to use.
