Low-slope roofs have roof slopes of less than 3:12, meaning that for every 12 inches of horizontal distance, the roof rises less than 3 inches. This product category is a common type used in the commercial roofing industry, but it is not unusual to also see low-slope roofs on residential buildings.

Low-slope roof types available on the market are made from a wide range of materials, including metal, concrete, clay or plastic tiles, or asphalt shingles. Low-slope metal roofing, in particular, is often used for commercial buildings because it can last for up to 50 years with proper maintenance.

A low-slope roof makes a great pair with any industrial building. Roof assemblies with a low roof pitch are often less expensive to install and maintain than steep-sloped roofs. Furthermore, this type of roof system can also be used in residential construction, especially if the homeowner has a budget to stick to.

A low-slope roofing assembly is ideal for buildings in areas that experience heavy snowfall, as it can prevent snow and ice accumulation on the roof. Low slope roofs also allow for more ventilation and better air circulation, which can help to reduce the risk of mold and mildew growth.

Roofing materials for low slope roofs

There is a wide range of building materials that can be used for low-slope roofing systems. Some of the most popular materials are asphalt shingles, metal, and slates. Asphalt shingles work best for low slope roofs because they are a low-maintenance option that can last for more than 50 years.

Metal roofs provide a durable and long-lasting roofing material with the added bonus of being more fire-resistant when compared to other options. Slate roofs are expensive, but they impress with their durability and have a promising life expectancy.

Low slope roofs can also be made from bitumen. Bitumen is a viscous material known for its durability and water resistance. Low slope roofs composed of layers of bitumen can prevent water damage and ice dams.

One challenge with low-slope roofs is that they are more susceptible to leaks and moisture damage. A way to combat this is to install insulation. The most popular insulation options are spray foam and rigid foam insulation.
Spray foam insulation is a spray-on product that forms a seal around any cracks or gaps in the roof. This type of insulation is effective at preventing moisture damage and energy loss. Rigid foam insulation comes in panels or boards and is installed over the roof decking to reduce energy loss by up to 50 percent.
