Roofs are exceptionally vulnerable to the elements. Extreme weather conditions like strong wind, hurricanes, hail and heavy snow can have an impact on the lifespan and functionality of a roof. Even after the rain has stopped and the snow has ended, moisture seeping into cracks, nooks, or crannies in the roof can cause damage over a period of time. Moisture can also cause a variety of other problems, such as mold and pest infestations.
What About Day-To-Day Issues?
Despite all the potential problems that can be caused by extreme weather conditions, even normal day-to-day weather can make an impact and damage a roof. In fact, in some cases it is the day-to-day weather that can really cause a roof to deteriorate. The reason roofs can be damaged so badly from daily weather is that these structures are often exposed to thermal shock on a daily basis. But what exactly is thermal shock?
What Causes Thermal Shock?
When exposed to scorching hot sun, your roof absorbs radiated heat. When radiated heat is suddenly cooled off by a rain shower, thermal shock may occur. Heat absorption causes roofing materials to expand. The sudden application of cold can cause these materials to contract. This sudden fluctuation can damage your roof because it can cause the materials to crack.
Sudden temperature changes can also cause a separation of the joints and seams in a roofing structure. Flashing may come loose due to frequent compression and expansion, especially when the weather in the area is constantly changing. It may be best to have a roof services company examine the structure to remedy any existing damage and prevent future damage as well.
How to Prevent Damage From Thermal Shock
Despite the threat of thermal shock damage to your roof, the good news is you can do something to prevent it. One method is to cover the roofing with a coating. A roof company can do this, although you can do it yourself. Roof coatings are made from adhesive fluid that turns into an elastic membrane after drying. This coating may be as thin as a coat of paint or as think as ten times that thin amount.
When you or a roof service apply this elastic membrane to your roof, it does the expanding and contracting and prevents the cracking and damage caused by thermal shock. It also comes with an added bonus; this coating can help prevent UV rays from further damaging your roof.
Prevention is the best way to keep your roof in good condition for a long time. To further protect your roof, be sure to call an experienced roof company if you notice any damage to your roof. These experts can both repair your structure and make sure no further damage occurs!
