Roofing Facts: Fascinating Facts About Flat Roofing
Flat roofs are a popular roofing style, especially with commercial buildings. You probably come across dozens and hundreds of flat roofs every day. But a typical roof is incredibly complex, with different designs and a plethora of secrets. Below is a list of some fascinating facts that will spike interest and inform you about flat roofs.
Flat Roofs Aren’t Always Flat
Did you know that flat roofs are never 100 per cent flat? Well, flat roofs are designed and constructed to have a few degrees of the slope to allow water and debris to drain off efficiently. When it comes to roofing, the slope is measured in rising every 12 inches. For instance, if a roof is raised 5 inches vertically for every foot it runs, it would be a 5/12 slope. Flat roofs usually have a slope of 1/12 or less.
You Should Inspect Your Flat Roof Twice a Year
Most property owners hardly notice issues with their roofs until it’s too late, especially when they don’t inspect the roof regularly. At this point, repairs tend to be costly and roof replacement could be inevitable. However, you can avoid such issues if you ensure that your roof is regularly inspected, usually after every six months or less depending on the surrounding weather conditions. Consider proper fall protection for your property as per the work at height regulations. High roofs, for instance, tend to experience more and stronger winds, hence the need for wind resistant demarcation for your safety.
Roof ventilation is very essential to your roofing system. Your flat roof needs to breathe. This will allow for removal of warm, moist air from your property as cooler, drier air enters. Absence or poor ventilation can cause condensation build-up inside the building, which can damage walls, insulation, and wood.
Where You Live Can Dictate the Style of Roof to Install
Some roof styles just work better in certain climates and regions. Some work best in colder climates and others in warmer climates. Some are also more wind resistant than others. Flat roofs, in this case, can encourage water pooling and might be your best choice in a drier, less rainy climate. Your geographical region can also dictate the roofing material to use. For instance, metal roofs may not be efficient in areas near salty lakes due to the risk of corrosion.
A Leak May be Far from Its Origin
By the time you notice a leak on your roof, the water could have actually travelled several inches to feet from the origin of the issue. Therefore, it’s not safe to assume the problem is just above the leaking point. Ensure to do a thorough inspection around the leaking area to ensure you identify and fix the problem as soon as possible.
Avoid Covering an Existing Roof
Covering an existing roof may seem like an inexpensive, simple way to fix a roofing issue. However, a double-layered roof can cover up major roofing problems that could get worse if not addressed soon enough. It also adds weight to your roof, which could become a major issue if the maximum weight capacity is exceeded. When doing the repairs, consider replacing the part of the roof with an issue instead of covering it up.
