Here are the Key factors:

  • Definition and Characteristics-

Steep-slope roofing refers to roofs with a slope of 3:12 or greater, meaning for every 12 horizontal inches, the roof's elevation changes by at least 3 inches. This category primarily includes roofs of residential homes and some commercial buildings. The most common materials used in steep-slope roofing are asphalt shingles, wood shingles, slate, tile, and metal.

On the other hand, low-slope roofing systems have a slope of less than 3:12. Hence They are predominantly used for commercial, industrial, and some flat residential roofing. Therefore roofing systems must be watertight. moreover,  typically composed of multiple layers to prevent water infiltration. 

  • Design Considerations-

The design considerations for steep-slope and low-slope roofs vary significantly. Steep-slope roofs designed to be shed water quickly due to the effect of gravity. Moreover, as such, they usually have visible, aesthetically pleasing outer layers. 

  • Performance and Maintenance-

The performance and maintenance requirements for these two types of roofs also differ. Steep-slope roofs, particularly those with asphalt shingles, typically require more frequent maintenance and may have a shorter lifespan due to their exposure to the elements. On the other hand, low-slope roofs may require less regular maintenance. Therefore they do require regular professional inspections to ensure the multiple layers of roofing remain intact and functional.

The difference between steep and low-slope roofing:

Steep-slope and low-slope roofing systems differentiate from each other in various ways, including their design, materials used, functionality, and maintenance requirements.

  • Design and Definition-

Steep-slope roofs have a slope of 3:12 or higher, meaning that for every 12 horizontal inches, the roof's height increases by at least 3 inches. On the contrary, low-slope roofs, often referred to as flat roofs, have a slope that is less than 3:12.

  • Usage-

Steep-slope roofs are commonly found in residential buildings due to their aesthetic appeal.  therefore also seen in some commercial buildings. hence  Low-slope roofs, however, are therefore mainly used for commercial. moreover, industrial buildings as they provide efficient coverage over large areas and additionally allow for equipment to be on rooftops.

In contrast, low-slope roofs use materials like built-up roofs (BUR), single-ply membranes (such as TPO, PVC, EPDM), or modified bitumen, focusing more on durability and water resistance.

Final Thoughts:   

While steep-slope roofs may require more frequent maintenance due to their exposure to the elements, low-slope roofs demand regular professional inspections to maintain the integrity of their layered structure. Each type of roof has its own unique advantages, and the choice between a steep-slope and a low-slope roof often comes down to a building's design, location, intended use, and the owner's aesthetic preferences and budget.
