RICOWI Best Practices Guide
Properly designed, installed and maintained roofs can significantly reduce or prevent damage to buildings and their contents from natural hazards. Weather events such as windstorms, rain, fire, hail, ice, and snow accounted for an average of $21.8 billion dollars in insured property losses annually from 2003–2012¹. This damage can be further intensified by weathering and pest damage.
This “best practices” field guide for roof systems is a joint effort between the Roofing Industry Committee on Weather Issues (RICOWI), the Insurance Institute for Business & Home Safety (IBHS), and several roofing industry associations².
The manual contains information designed to help users more accurately evaluate a roof’s current condition taking into consideration several factors, including age and weathering. In addition, the guide outlines the available industry resources that contain roof-related installation, maintenance, repair and replacement practices. This information may help identify greater opportunities for repairing damaged roofs as opposed to replacing the entire roof following weather events. Such information is essential for contractors, building inspectors and code officials, roofing consultants, insurance professionals, and residential and commercial building owners, among others. By providing a summary of the available resource information, RICOWI and IBHS hope to create a consistent stream of guidance from a variety of professionals to residential and commercial consumers, eliminating confusion and ensuring that best practices are widely known and followed.
The manual also contains key information about roof product manufacturing and product identification. Because it is electronic, this material can and will be updated periodically as new information becomes available, and as products and building codes change. Helpful illustrations (e.g., graphics, photos and videos) are included herein, as are links to other valuable industry resources.
