One of the common problems that people worry about with flat roofs is how water can pool and cause damage. Water shouldn't be your only concern though, since these other 3 things can threaten a flat roof.
There are several ways that temperature can threaten a roof. Not only is an elevated temperature a concern, but fluctuating temperature can cause problems as well.
Thermal shock can occur when there's a large difference between what is the coldest and hottest temperature in a single day. This is because hot temperatures cause roofing material to expand, and cold temperatures will cause the material to contract. It can cause problems with joints, seams, and flashing that will crack, tear, or separate from your roof.
When a roof is exposed to very high temperatures for an extended period of time, it will cause volatile ingredients found in roofing tar or other materials to evaporate. It will cause the roof to become weak, and reduce the overall lifespan of the roofing material.
Wind can be a powerful force that will cause damage to your flat roof. Even though the roof is designed for withstanding wind forces, it can still be susceptible to damage when winds are very strong.
The suction effect can occur when fast winds flow over some parts of a roof, which cause low pressure in some place and high pressure in others. It can cause some portions of a roof to push in while another portion will bulge out. Lift can also occur, when a poorly anchored section of roofing material is lifted off the roof.
Thankfully, issues concerning wind are minimal if your roof has been properly maintained. This can be done by inspecting the roof to verify that flashing is attached, and that seems are sealed correctly.
Since the design of a flat roof is different from a sloping roof, they typically see more weight put on them. The weight comes from things as common as people walking on the roof, but it can also occur due to debris or snow accumulation. If there is an excessive amount of weight on the roof, it can cause problems with the roof's structural integrity.
You can prevent this from happening by being diligent about removing excess weight, like snow, as soon as possible.

One thing I never realized about roofing is what a difference it can make in the appearance of a home. The roofing on my home was more than 20 years old before we got around to replacing it. As we were working with our roofing contractor to choose the materials that we wanted to use, I learned quite a bit about the many, many options that we had to consider. Our blog will show you several of the options and provide you with facts about each type of material that you can use. Hopefully, what we have included here will help you choose the roofing that will look and perform the best on your home.
