What is the appropriate distance to separate the siding from the roof's surface?

The appropriate distance to separate the siding from the roof's surface is 1 to 2 inches. This gap is crucial for several reasons. First, it helps to prevent moisture accumulation at the juncture where the siding meets the roof. When siding is installed too close to the roof surface, it can trap water, leading to potential issues such as rot, mold, or deterioration of both the siding and roofing materials over time.

Furthermore, this separation allows for proper drainage and airflow, which are essential in ensuring that moisture can evaporate rather than being trapped. This distance also helps to create a physical barrier that can prevent pests from easily accessing the siding and nesting between the materials, enhancing the longevity and integrity of the building envelope.

Maintaining this recommended gap can contribute to the overall durability and performance of the roofing and siding systems, safeguarding against many common issues that can arise from improper installation practices.
