What to do if snow damages your home WXYZ-TV and last updated 2021-03-13 08:26:18-05 COLORADO SPRINGS, Colorado â It can be dangerous when snow piles up in feet. Colorado building codes were written with heavy snowfall in mind. However, falling tree limbs and gutters clogged with ice dams can cause damage to homes, power lines, and vehicles. In extreme cases, heavy snow loads can also lead to roof collapses. That happened in the Denver area during the historic snowfall in March 2003. An abandoned building and a gas station, both with flat roofs, experienced collapses when more than 31 inches of snow fell on the metro area.
