What is Roof Flashing?
Flashing is an important part of a roof that keeps your home dry and safe from water damage.
Most of the time, it is made of metal, but it can also be made of plastic or rubber.
Roof flashing is put in place at key spots on the roof, like where it meets a wall, chimney, or skylight, to seal any cracks or gaps that could let water in.
Its main job is to stop leaks and moisture problems, which protects the structure of your roof and the inside of your home.
Roof Flashings Uses
Roof flashings are important to prevent water damage to the roof structure because they can do things like:
- They keep water from getting in and causing problems like rot, mold, rust, and corrosion.
- Flashings keep water from getting into weak spots and direct it to the gutter and downspout.
- They also fill in cracks and gaps between the roof and other parts of the house.
All in all, roof flashings make the roof last longer and work better, protecting insulation, wiring, and interior surfaces.
Type of Roof Flashings
Roof flashing can also have different shapes and sizes, depending on the area of the roof that needs to be covered.
Some of the common types of roof flashing are:
- End-wall flashing:
This type of flashing is applied where the upward slope of a roof meets a wall. It covers the gap between the wall and the roof shingles or tiles. - Wall flashing:
This type of flashing is applied where a wall intersects with a roof. It covers the gap between the wall and the roof deck or underlayment. - Valley flashing:
This type of flashing is applied where two sloping roofs meet at an angle. It covers the valley formed by the two roofs and directs water away from it. - Step flashing:
This type of flashing is applied where a roof meets a vertical wall or chimney. It consists of rectangular pieces of metal that are bent at 90 degrees and installed in an overlapping manner along the edge of the roof. - Drip edge flashing:
This type of flashing is applied along the eaves or lower edges of the roof. It prevents water from dripping behind the fascia board or gutter. - Vent pipe flashing:
This type of flashing is applied around vent pipes or other protrusions that penetrate through the roof. It seals the hole around the pipe and prevents water from entering it.

Similar to sealants but more rigid and less flexible. Used to fill cracks or holes in roofs or walls, available in latex, butyl, or other materials.

Tapes:
Adhesive strips for bonding or joining surfaces together, made of rubber, vinyl, foil, or other materials. Useful for taping vents, pipes, or seams.
Keep in mind that tapes may lose stickiness, tear, wrinkle, or curl due to moisture or heat.
