Low pitched roofs are a popular choice for contemporary house design and commercial buildings. However, as mentioned before, low slopes can create potential problems for your Edmonton home if you do not choose the appropriate roofing materials or do not have them installed properly.
The main concern with low slope roofs is reduced drainage. Water is far more likely to pool on the roof top, which can lead to serious problems, such as roof leaks. In colder climates, like what we experience here in the Edmonton area, the freeze-thaw cycle of pooled water is particularly concerning for flat roofs.
Temperature changes can cause roofing materials to shrink or expand, creating gaps between material. Water is far more likely to seep between any small crack or gap because of the low slope and when that water freezes it also expands, causing potentially irreparable damage.
Water infiltration can lead to cosmetic and structural damage of your house, as well as mold and mildew growth, which can have serious health implications for you and your family.
