How to Measure Snow Load on the Roof
Snow becomes a threat on a house when the buildup is already beyond the loading capacity of the roof. Depending on the density of snow -- affected by the rate of fall -- and the type of roofing, it can cause significant deflection that increases with the chance of total collapse. However, if the weight of snow will be predetermined as well as the loading capacity of the roof, collapse can be prevented.
To measure the snow loading capacity of the roof, the area of the roof should be determined by multiplying the length and the width of one face of a gable-type roof and multiplying the result by the number of faces. Computation of the area varies according to the shape of the roofing. After knowing the area, assume a certain measure of the thickness of snow by measuring a maximum holding distance from the eave.
Thickness can be measured by placing a ruler tangentially on the surface of the eaves. If snow is expected to fall at the edge in 6 inches thickness, then that is the maximum thickness that the roof can bear. Add 2 inches extension to obtain a more secured result. These data are important in designing a roofing system or putting up additional supports. Roofing professionals in cities like Lincoln, Nebraska use these data for designing strong roofing systems.
Multiply the thickness by the area of the roof to determine the maximum volume of snow expected to accumulate during a snowstorm. For example, if the area of the roof is 50 sq. meters, multiply it by the thickness converted in meters, whereas 8 inches equals 0.203 m. Professionals in roofing lincoln ne recommends would compute for exact volume to determine a reliable weight value.
Weight is measured by multiplying the volume with a constant density of snow. Using the sample data, the volume is 10.15 cu. m of snow. Multiply this value by the maximum snow density at a temperature of 100 degrees Celsius of 287.52 kg/cu. m. Professionals in roofing lincoln ne has use this standard density for snow.
The maximum weight of snow in this scenario is 2918.33 kg. Professionals in roofing lincoln ne recommends would use the value as the basis for the design of roofing system applicable for the house. Most of the time, this value is associated with the arrangement of trusses or the type of roofing material to be used.
