What is the standard measurement for roll roofing width?

The standard measurement for roll roofing width is 36 inches. This dimension has been widely adopted in the roofing industry as a standard, making it easier for installers to work with and ensuring compatibility with various underlying materials and installation methods. Roll roofing is typically used for flat and low-sloped roofs, and its consistent width facilitates a more streamlined installation process as many roofs will require overlapping sheets for proper sealing and waterproofing. The 36-inch width strikes a good balance between manageable size for handling and efficiency in covering large surface areas. In contrast, other measurements such as 30, 33, or 40 inches are not standard for roll roofing, potentially leading to complications in sourcing materials or consistency in installation practices.
