Hail damage to modified bitumen roofs.

My question is about a formula amica used to determined the amount of hail damage in order to replace the roof the adjuster wrote to me saying in his letter the roof replacement is determined by the amount of damage on each slope and there was one minor hail strike damage found on the front slope so the replacement roof needs at least 8 hail strikes to any 100 square foot test area based on. The high tensile strength of both variants of modified bitumen make them very resistant to physical damage and they require little to no roof maintenance. According to the national oceanic and atmospheric administration noaa there was a total of 4 611 hail storms in the united states during the year 2018 with 2019 ending on a higher number as of year end more than 5 396 hail events were recorded although most people think that property and roof damage only occur in rare instances with larger than average hailstones even the smallest. For asphalt shingle roofs or roll roofing or mineral granule coated modified bitumen covered roofs continue hail damage investigation by looking in your roof gutters and on the ground for large amounts of mineral granules lost from the roof.

Built up asphalt roof systems are commonly gravel surfaced. Bitumen roof advantages and disadvantages. Since this roofing system actually has a low slope water doesn t pool on the roof surface and this means it s unlikely that it will experience moisture.

The gravel provides protection to the underlying roof membrane from both foot traffic ultraviolet uv exposure as well as hailstones.
