How do you calculate the weight of snow on a pitched roof?

To calculate the weight of snow on a pitched roof, you can use the formula: Weight = (Snow load in pounds per square foot) x (Pitch factor) x (Area of the roof in square feet). The snow load is usually provided by building codes or meteorological data, and the pitch factor accounts for the angle of the roof. It's important to consider these factors when estimating the weight of snow on a roof to ensure structural safety.


Need to fill 30000 gallon tank with water how much roof surface area do you need with one inch rain fall to fill the tank?

To calculate the roof surface area needed to fill a 30,000-gallon tank with one inch of rainfall, you will need to know the collection efficiency of your roof. A common value is around 90%. With that efficiency, you would need a roof surface area of approximately 6,667 square feet to collect enough water to fill the tank from a one-inch rainfall.

What is the weight of 1.38 inches of rain water on a roof 114 feet by 150 feet.?

To find the weight of the rainwater on the roof, we first need to calculate the volume of rainwater that fell on the roof. The volume can be found by multiplying the area of the roof by the depth of rainwater. So, volume = 114 ft * 150 ft * 1.38 inches. Next, to find the weight of the rainwater, multiply the volume by the density of water (62.4 lbs/ft^3).
