Those who live in snow intensive areas know that when the big storms come through, it may be necessary to resort to using a roof shovel to eliminate the snow load on the roof. Architects who design homes need to know the local area to build properly for the weather. More than just good design, they learn about structure and materials. Structural engineers focus even more in depth on properly designing buildings so they can withstand the forces of nature.
Wind pressures, earthquake and fire preparedness are some of the things that govern materials choices. Proper distribution of weight load is another consideration. If an architect or engineer knows the builder will use 5/8 inch instead of 3/4 inch plywood for roof decking, then they know roof trusses will need to be closer together. In this way, they can prepare for future winters when the roofers may have installed a third layer of roofing instead of doing a roof replacement.
Along comes Mother Nature to drop two, three, or four feet of snow on top of the shingles. Snow weighs anywhere from five to twenty-five pounds per square foot, depending on wetness. If you hear creaks coming from the direction of the attic, it isn’t ghosts, your house is complaining of the load. It’s time to get that load off the roof to protect your home. So head to the hardware store to get a roof shovel and tackle snow removal safely or hire a contractor to do it for you.
