When it comes to roofing, there are many factors to consider. From functionality to aesthetics, the design of your roof is an important decision. But one of the most crucial elements is the slope. The right slope can make all the difference in a high-performance roofing system.
The minimum and maximum roof slope limits vary depending on the type of roof system and project. Here, we'll discuss the NRCA code requirements and roof slope guidelines, as well as other factors to consider when installing a flat or low-slope roof. The National Roofing Contractors Association (NRCA) code requires that roofs have a minimum slope of 2 inches per foot. This means that for every 12 inches of horizontal distance, the roof should rise at least 2 inches. This is the minimum requirement for most roofs, but some may require a steeper slope.
For example, roofs with valleys or complex geometries may require a slope greater than the minimum. When installing shingles on a low-slope roof, other methods are required to avoid a short-lived leaky roof. As the terrain is a low-slope roof, the installer will install the 3-tab shingles in the opposite direction than usual, leaving the solid black part of the tile exposed, instead of the 3 tabs (which are covered by the previous tile).Vertically-stitched metal roofs are sheets of metal that look flat in the center and vertical ribs at the edges of the panel, creating a smooth and aerodynamic appearance. In addition, steeply sloped roofs are more expensive to install, making them too expensive for many businesses or large buildings. Flat roofs (0 to 2 inches of slope) are flatter than low-slope roofs and are sloped enough to drain water. It is important to note that a roofing material is only as effective as its details and installation.
The self-sealing properties of roof shingles may not work properly when installed in this inverted orientation. An important consideration when installing a new roof on a low-slope roof designed by Wright is to allow for a certain slope while still respecting Wright's design objectives. However, as we explained in detail in UNDERLAYMENT DOUBLE vs SINGLE, it is usually quite easy to determine if there is a single-layer or double roofing felt installation by looking at the amount of overlap of the roofing felt layers on the end of the gable roof. In addition, low-slope roofs require frequent maintenance and inspection because they are more likely to leak.
