There’s still a lot of work to be done in the USA as the country finally gets on the road to recovery from the COVID-19 pandemic. For Texas, however, pandemic recovery is also compounded by repair and recovery from one of the worst snowstorms in years. The state was unprepared for the effects of climate change. The unseasonably cold and hostile winter storms reminded locals that cold weather is not as harmless as some might imagine.
As climate change progresses, the state is likely to experience more weather like this. But how exactly does weather affect a roof? We all know that a roof is there to shelter and protect us from the weather. But what is the weather doing to the roof during this time?
This is a factor that most southern states are unprepared for. Unlike rain storms, snow storms bring with them weight as snow accumulates. Roofs in northern states are built and reinforced with weight accumulation in mind, but this isn’t always the case for roofs in warmer climates.
If a roof isn’t properly structured to take the weight of snow, a severe snowstorm can collapse the roof. As weight accumulates in places with little tolerance for it, structural weaknesses worsen and eventually break.
Expansion & Contraction
Materials behave differently depending on the temperature. When things get hotter, materials tend to expand. However, when things get colder, they contract. The opposite, however, is true of liquid materials, such as water. This means that a roof, especially those with components like metal, will expand in summer and contract in the winter. This stretching and contracting can, over the years, eventually lead to a weakening of the materials, resulting in breaks and cracks.
If this is combined with water, the process accelerates. Water getting into a crack is bad enough, but if the temperature drops and the water freezes to ice, expanding ice can make cracks and breaks grow larger.
Water is required for life, but it also has an erosive effect. Some materials break down when they get wet, while others change to provide a more suitable environment for other organisms, such as algae, moss, and mold. Water penetrating a roof and getting into a structure can ruin insulation, which raises heating and cooling bills. However, it can also lead to mold infestations, which can threaten the health and safety of people in the building if it’s a particularly aggressive variety of mold.
Finally, summer storms can rise in wind intensity. A slight breeze doesn’t do much to a roof, but gale-force winds from a tornado, for example, are capable of tearing up roof components. Strong winds can even send other objects flying into the air, such as tree branches, that crash into a roof. This can result in dents, damage, and missing pieces.
