Engineers caution that residents wanting to clear their own roofs face greater risk of hurting themselves or damaging roofs than from a collapse.

The roof collapsed at a South Anchorage gym during a fitness competition. The Anchorage Office of Emergency Management cautioned residents that the city has had near-record snow conditions this winter, and residents should consider the snow load on their roofs. Officials also warned that property owners should exercise extreme caution if removing snow from their roofs themselves.

The library in Palmer partially collapsed on Wednesday evening near closing time.

The winter storm that dumped snow and freezing rain on the Interior over the holiday weekend also caused the roofs of two buildings in Delta Junction to partially collapse Sunday.
