If a home is not well prepared or designed sufficiently the weight of extremely heavy ice and snow can cause a devastating roof collapse. This can cost thousands in repairs and cause injuries to those inside of the home.
The National Oceanic and Atmospheric Administration (NOAA) presently puts the current weight of snow on the ground at 33lbs per square foot. If your building suffers from poor design, poor construction, lack of maintenance, old and out-of-date code your building may be subject to roof damage from snow.
SteelMaster offers several models that are able to protect people and property from heavy snow.
Every steel Quonset HutTM is specially engineered to handle any extreme weather event, including blizzards and the weighty snow they leave behind.
Our buildings follow the snow load provisions required by the ASCE 7-95 and those of the IBC. Many localities and zip codes also add their own specific codes for their areas. The building code first identifies the ground snow load, which helps to calculate the uniform design snow load on the building’s roof.
The ground snow load values are provided by a map created by the National Weather Service. These numbers represent the peak snow load that has a 50 yearly mean re-occurrence interval of a 2% probability of being exceeded in any given year.
There are a few things to consider when determining snow loads including ground snow value, occupancy of the building, type of snow, wind exposure, roof slope, roof shape, roof obstructions, and the thermal condition of the building.
Most buildings can withstand about 20 pounds per square foot of snow. Experts recommend that building/homeowners remove anything over 18 inches of snow from low pitch roofs. This can be extremely risky to the person removing the snow and the building. Once a roof becomes overstressed, the possibility of collapse is not too far off.
All snow is not created equal. There are actually different kinds of snow depending on the atmospheric and geographic conditions. Snowfall in the West is drier and lighter than that in the East where snow tends to be moisture-laden and much heavier. One foot of powdery snow is three pounds PSF while the wet, heavier snow can weigh ten times that much.
SteelMaster’s arches are able to handle the load in any region. Our arches are created with commercial grade, high quality steel that can be customized to accommodate extra heavy snow loads in areas that experience frequent snow storms. Any of our models can accommodate these loads including the A-Model, S-Model, the classic Q-Model and the X-Model which is the most popular for heavy snow. We also offer a C-Model that serves as the best carport in snowy climates.
Two of the most important things to consider when determining if your building is strong enough to handle the heavy snow are the slope and pitch of the roof. SteelMaster’s X Model has a 4:12 pitched roof which makes it easier for heavy snow to slide right off. We also have an R model roofing system that is custom made to withstand extreme weather conditions. Our solid steel arches also make the best portable garage for snow and the best roof design for snow.
To prevent a snow-related structural failure, a SteelMaster metal Quonset HutTM is the safest option.
