Types of Commercial Roofs All Seasons Industrial Roofing

When it comes to roofing, commercial buildings have a very different set of requirements to domestic buildings. The main things to bear in mind when designing a commercial roof will be durability, stability and cost effectiveness. This dictates the type of roof that is used, but there are of course, advantages and disadvantages to every type of commercial roofing system. This article will give you an overview of the most widely used types of commercial roofs so that you can make a more informed decision on your building.

Flat Roofs

Flat roofs are one of the most common types of roof for commercial buildings. Commercial flat roofs can be significantly more cost effective to build than pitched roofs or steep slope roofs because they require less material due to the fewer square feet to be covered. They are easier to install, resulting in lower initial installation costs, and maintenance and repair costs are generally lower as a rule. Maintenance and drain cleaning is easier on flat roofs since workmen can walk easily and safely, regardless of weather conditions. Flat roofs are versatile in their design, covering the roof entirely whilst utilising the space that’s on offer and many commercial buildings use the flat space to install solar panels, or units that would take up too much space inside.

Low Sloped Roofs

Very similar to flat roofs, low-sloped roofs are commonly found at the tops of large-scale buildings like factories, industries, warehouses, and apartments amongst others. The pitch of low-sloped roofs allows for water run off and the roof design directs the water to where it should go, such as valleys, saddles and drains. The roof area is less than with high-pitched roofs, requiring fewer square footage of roofing materials, resulting in a cost effective solution. Low-sloped roofs offer easier and safer conditions for roofers to work on than high-pitched roofs or steep slope roofs and commercial roof installation, repair and replacement is easier to perform. There is less chance that the building owner will need to call repairmen out to manage water problems, since the slight pitch does not allow for standing water or puddling.

Pitched Roofs

With probably the most aesthetic value, they are the most expensive of the three basic categories. These roofs have absolutely no problem with drainage being so steep, and this is the most advantageous edge they have over other types of commercial roofs. The steeper the roof structure, the easier it is for liquid and debris to roll off. Ultimately this means less risk for water build-up that could lead to leaks and mould damage. Overall, having a steep-sloped roof could reduce your needs of repair and maintenance, compared to a flatter, less inclined roof. With no risk of water accumulation and eventual roof leakage, pitched roofs have the longest lifespan of the three types.
