Roof flashing is a thin material, usually galvanized steel, that roofers use to direct water away from critical areas where the roof plane meets a vertical surface like a wall. Flashing is installed around roof features, such as vents, chimneys and skylights, to prevent water infiltration.
Types of Roof Flashing
There are several types of roof flashing:
- Step flashing – thin metal sheets layered from the bottom up, overlapping to form ‘steps’ that water runs down
- Cap flashing – connects thin metal pieces to points where the roof meets a vertical surface, like a wall, to keep water away
- Continuous flashing – long pieces installed in vulnerable areas, like the joint between a wall and sloped roof
Properly installing flashing and ensuring it stays in good condition helps reduce long-term roof repair expenses. Having professionals carry out flashing installation is best, as the process varies depending on the materials and techniques used.
The Importance of Flashing
It’s crucial every roof needs flashing. You have options – aluminum, steel, copper.
Properly installed and maintained flashing reduces roof repair costs. Professionals should install flashing as the process varies by material and technique.
