The severity of hail damage to residential and commercial roofs depends on several parameters including the age and type of roofing material, the roofing assembly, hail size, and roof slope, among others. Asphalt shingled roofs comprise a large percentage of insurance claims submitted for roof-related hail damage. For asphalt shingled roofs, hail damage typically consists of radial/circular areas of granule loss, which constitute latent damage and may affect the future performance and lifespan of the shingles. The severity and extent of hail damage to asphalt shingled roofs is not as visually apparent as compared with some other common high-slope roofing materials, such as metal panels, wood shakes, and clay/concrete tiles. Assessing the extent of hail damage to shingled roofs and developing a scope of repairs can be difficult. Furthermore, guidelines for such assessment are not well established. Based on the authors' experience, we propose guidelines and procedures to assess the extent of hail damage to asphalt shingled roofs from which a scope of repairs can be developed. A cost analysis for the consideration of repair versus replacement is also presented. |
