Hail Damage
According to the National Weather Service, hail results in roughly $1 billion in damages per year in the United States. Hail threatens most areas of the Unites States, and the country sustains an average of 3,000 hailstorms per year. While asphalt shingles are designed to resist hail, severe hail poses a threat to their integrity and functionality, particularly where the shingles are not firmly supported, if they cover old layers of roofing, or if they are aged and otherwise inherently more prone to damage.
After severe hail storms occur, hail damage to asphalt shingles can be visually obvious and easy to diagnose. However, thunderstorms that produce severe hail commonly also produce a large volume of smaller and not necessarily damaging hail,, which generally produces more problems other than those caused by severe hail alone. For this reason, damages from a typical severe hailstorm are often most intense in a limited area, decreasing in severity as one moves away from the area of greatest damage. Because the effects are then inconsistent over the area affected, one must have a thorough knowledge of asphalt shingle construction, installation, installation practices, wear and tear, manufacturing defects, etc., as well as hail damage before an educated conclusion may be drawn on a particular roof.
Donan Engineering studies thousands of asphalt shingle roofs per year for hail damage. We apply a systematic and logical methodology to each roof, where we place just as much emphasis on the collateral damages from hail (or lack thereof) as we do on the condition of the shingles themselves, so that a confirmed correlation may be made between what is documented on the roof and what can be conclusively linked to a particular hail event.
Is the damage new or old? When did the damage occur? Does it warrant repair or replacement? Is the entire roof a complete loss or are there only a few shingles that warrant replacement? Are there unintentional or intentional man-made damages? Our team of professionals is trained and experienced to deal with these and other complicated issues.
