Mendenhall Valley Roof Collapse Under Heavy Snow

Recently, the region has experienced an exceptional amount of snow, leading to dangerous conditions for homeowners. Muir reported observing crackling noises before a segment of his roof gave way. Fortunately, no interior damage was sustained.

Background Information

• Date of Incident: January 8, 2026
• Location: Mendenhall Valley, Juneau
• Weight of Snow: Estimated at 41.6 pounds per square foot
• House Age: Built in the 1970s

This significant weight was based on data collected by the National Weather Service (NWS) in Mendenhall Valley. Historically, homes in Juneau constructed prior to 1991 were designed to handle a snow load of 40 pounds per square foot.

Advice from Experts

Nate Geary, a civil engineer, emphasized the importance of monitoring the weight of snow on roofs. He indicated that homeowners should look for warning signs such as deformation and popping sounds in the structure.

Geary recommends taking preventive measures like:

• Using a snow rake to clear eaves and overhangs.
• Ensuring vents are clear to prevent moisture buildup.
• Shoveling drainage paths on flat roofs.

He mentioned having to take action once his roof approached the critical weight threshold. He urged homeowners to be proactive with snow removal to prevent similar situations.

Looking Ahead

With forecasts predicting additional heavy snow and rain in the coming days, residents should remain vigilant. The potential for heavier and wetter snow could increase the risk of further structural failures.

Muir expressed his fatigue with the winter weather, stating that he had intended to replace his roof in spring. In the meantime, he plans to patch up the damaged area, advising others to clear their roofs promptly to avoid similar mishaps.

In conclusion, the recent roof collapse in Mendenhall Valley serves as a crucial reminder of the dangers associated with heavy snowfall. Homeowners must take preventive measures to secure their properties during the winter season.
