What does "strapping" refer to in roof construction?

Strapping in roof construction specifically refers to the installation of wooden or metal strips, also known as furring strips, that create a framework for roofing materials. This process is critical for providing a stable base upon which roofing materials can be applied, ensuring that they are properly supported and aligned. Strapping also serves to create an air gap, which can be important for ventilation, thereby helping to prevent moisture buildup and prolonging the lifespan of the roof.

In addition to its structural benefits, strapping can also aid in achieving the desired aesthetic when roofing materials are applied, as it allows for greater flexibility in the placement and orientation of those materials. This is especially important for certain types of roofing systems that require specific alignment to function correctly and maintain their durability over time.
