Wind Uplift of Asphalt Shingles

Research IBHS wind testing of asphalt shingle products has demonstrated that the most important factor affecting high-wind performance for self-sealing asphalt shingles is the strength of the seal between shingles. Self-sealing asphalt shingles contain a temperature-activated adhesive strip applied during the manufacturing process, which is used to adhere the lower-edge bottom surface of the exposed…

Relative Impact Resistance of Shingles

Research IBHS tests the impact resistance commercially available asphalt shingles using both 1.5- and 2.0-inch diameter laboratory manufactured hailstones using the IBHS hail impact testing protocol. Laboratory and field research by IBHS has shown that the impact energy and material properties of laboratory hailstone sizes can be directly related to typical natural hailstones in non-wind…

Near-Building Noncombustible Zone

Research Wildfire activity is on the rise and with this comes an increased impact on buildings, including homes and businesses, in the wildland-urban interface. Residents and business owners can take steps to reduce the risk to their property located in wildfire-prone areas. Eliminating fuels from the immediate area surrounding the building, as referred to as…

Vulnerable Populations

Vulnerable Populations Disaster-related loss prevention encompasses a wide range of activities that should be undertaken to increase the likelihood that homes, workplaces, and essential public buildings can survive a natural or human-induced catastrophe. Improving this capability must be a national priority, public health objective, economic imperative and humanitarian obligation. Nowhere is this more important than…

Economics of Community Disaster Resilience

IBHS has identified the following five concepts as central to the economics of community disaster resilience: (1) the importance of “going green and building strong”; (2) residential and commercial building performance; (3) emergency preparation and response as a shared responsibility; (4) building codes as a threshold, but not end goal; and (5) the need for…

Commercial Loss Control Tools

Using data and observations gathered during field and lab research, IBHS develops tools to help risk engineering and loss control staff evaluate and reduce risks and vulnerabilities to severe weather, including field tools to evaluate commercial structures and risk engineering bulletins that address specific natural hazards. Wind Loss Control Field Tools These materials will help risk…

Asphalt Shingle Patterns Identification Guide

Research After testing many asphalt shingle products, IBHS researchers learned there are specific characteristics that help distinguish one manufacturer from another. This guide was developed to help claims adjusters and underwriters identify manufacturers of installed shingles. Guidance [Members Only] Asphalt Shingle Patterns Identification Guide
