Roof flashing is a common practice to prevent ceilings from being damaged from the water seeping in. Typically comprised of different metals, it adds structural integrity to the roof. Water seeping through seams is a common housing problem which then causes roof leaks.

Roof flashing deviates the water away from these critical areas thus preventing leaks and structural damage. Roof flashing types vary from galvanized sheet metal to copper or aluminum but usually metal roof flashing is more common than any other types because of its longevity.

Flashing roof is important because the house isn’t built in one piece. Many different materials and individual parts come together to build the final thing. It is at these points where these individual parts are combined is where the leaks most commonly happen.

These areas are roof surfaces of dormer walls, skylight perimeters, chimneys, roof valleys. Because the flashing is done on many different surfaces, there are different roof flashing types to ensure proper protection for every surface.
  • Cap flashing: cap flashing adds another layer of flashing over the already existing flashing. It acts like the secondary structural integrity and hangs over the edge of the walls and railing so that water drops at a distance from the seams.
  • Step flashing: commonly done on the sloped roofs, step flashing is done at the base of the wall where the seam is. As water trickles down from the top of the roof, small metallic sheets under the shingles reinforces the water proofing and make sure that all the water has been dumped into the gutters and downspouts. Seams are further strengthened by adding tar at the joints where shingles meet walls.
  • Saddle flashing: flashing roof around the chimney is integral part in home designing. Many different flashing techniques are required to properly make areas around chimneys water proof. Saddle flashing diverts water away from the base of chimneys using a metallic sheet bent 90 degrees and placed at the base of the back wall of chimney. Water, when it hits the metal trickles down from the sides making this metal roof flashing.
  • Kickout flashing: placed at the very end of the slopping roof, it collects water at the end where wall meets roof and pours water into the downspout.

Even with all these types of flashing, security of your roof isn’t fully guaranteed unless you regularly have a professional inspect it. Damaged flashing poses a significant threat to the structure of roof therefore scuffed flashing usually means roof flashing repair is due.
