Significant snowfall and resulting snow loads have caused several roofs to collapse within the Flagstaff area. The City of Flagstaff and Coconino County are encouraging residents to check structures for signs of damage or stress. These signs can include:
Sagging ceiling tiles or boards, ceiling boards falling out of the ceiling grid, and/or sagging sprinkler lines and sprinkler heads
Sprinkler heads deflecting below suspended ceilings
Popping, cracking, and creaking noises
Sagging roof members, including metal decking or plywood sheathing
Bowing truss bottom chords or web members
Doors and/or windows that can no longer be opened or closed
Cracked or split wood members
Cracks in walls or masonry
Severe roof leaks
Excessive accumulation of water at nondrainage locations on low slope roofs
