Introduction

When it comes to roofing, one of the most crucial aspects to comprehend is the roof's slope. The slope not only affects the aesthetic appeal of your home but also plays a significant role in its functionality.

  • Water Drainage: A steeper slope facilitates better water drainage.
  • Material Choice: Some materials work better on specific slopes.
  • Structural Integrity: Certain slopes may require additional support.
  • Aesthetic Appeal: Different slopes provide varying architectural styles.
