2009 Ice Storms

Here we go again. over a million people are without power due to ice storms across the Midwest stretching down into Texas. Ice storms are a huge problem for buildings constructed in areas where they are not common.

One of the things that is happening is warmer temperatures in the outer atmosphere mean there is more moisture. When this moisture condenses it begins to fall as rain. If surface conditions are below freezing, the rain drops freeze and become ice. When upper atmosphere temperatures are cold the water falls as snow not rain. Snow is less damaging since it weighs about 1/10th as much as ice.

In addition to the power outages – we should anticipate an increase in building roof collapses. Steeper sloped roofs are better equipped to deal with this extreme weather where at least some of the ice will generally slide off. Flat roofs tend to accumulate the ice and are more likely to collapse from the load.

Some areas have been reported to already have about 6 inches of ice with another 6 inches potentially falling in the next 24 hours. Twelve inches of ice on a roof weighs about 60 pounds. That is a huge amount of weight for a roof since many roofs in areas that are not commonly exposed to the weight from ice and snow have been built to hold a minimum of twenty pounds. 

We should also anticipate problems with frozen plumbing and ice dams.

:099 Weak Garages

Suggested Review – :098

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:099 EcoTip:  The attached garage is usually one of the weakest parts of a home. This is because the large garage door is poorly supported in comparison to other areas of the house. When strong winds, tornados, hurricanes, floods or earthquakes hit the unsupported garage door, the weakness makes it easier for the walls to collapse. The garage roof falls and can pull the roof for the rest of the home along with it.

Tomorrow I will discuss bracing garages for greater duribility
