Introduction
Flat roofs have become a popular choice for both residential and commercial buildings due to their modern aesthetic, efficient use of space, and ease of installation. However, one significant aspect that often gets overlooked in flat roofing is the role of flashing.

In this article, we will delve into The Role of Flashing in Flat Roofing: Protecting Your Home from Water Damage, exploring its types, installation methods, maintenance tips, and its undeniable importance in safeguarding your property.
What is Flashing in Roofing?
Understanding Flashing
Flashing is a material, typically made from metal or plastic, designed to direct water away from critical areas on the roof.

Without effective flashing, water can infiltrate these vulnerable spots, leading to costly repairs and potential structural damage.

Base Flashing vs. Cap Flashing

Step Flashing
Step flashing consists of L-shaped pieces that are placed between shingles or roofing materials along vertical surfaces to guide water away effectively.
