What is installed around the roof edges to prevent water seepage into a home?

Flashing is installed around the roof edges to effectively prevent water seepage into a home. This material is typically made from metal, although it can also be made from other waterproof substances, and is strategically placed at various crucial points on the roof, such as around chimneys, vent pipes, and where the roof meets the walls. Its primary function is to redirect water away from vulnerable areas and into the gutters, thereby minimizing the risk of leaks and water damage in the interior of the home.

Flashing plays a vital role in maintaining the integrity of the roofing system, especially in regions prone to heavy rainfall or snow. It creates a barrier that prevents moisture from penetrating beneath the roofing material, which can lead to mold, rot, and other serious structural issues over time.

While options such as shingles are important for the overall waterproofing of the roof, they do not specifically address the seams and joints where water is most likely to seep in. Other options like edging and stripping are not standard terms related to waterproofing in roofing systems. Thus, flashing stands out as the essential component designed to combat water intrusion in home roofing.
