Flashing Where Two Roof Lines Meet

If you don t direct water from the roof into.

Flashing where two roof lines meet.

Remember to caulk the underside of the flashing with a sealant. This material is available with a v or w shaped profile and is placed over the top of the building felt before the roof s finishing material is installed. Drip edge metal valley flashing dormer chimney and kickout flashing are types of roof flashing that shed water away from the connections between roofs walls chimneys and other building assemblies. Slide the right edge of the flashing under the highest roof pitch.

Now nail this first flashing at both its far ends. If leaks continue to occur from ice dams consider installing roof edge heating cables. The edge of the roof has thin metal flashing that helps water drip off the roof without damaging the home or causing a leak. Ground zero for roof rot is often where roofs meet walls.

Val ley flashing protects the valleys where two roof planes meet. Step flashing protects the joints between the roof deck and chimneys or dormers. Place the 2 by 4 inch piece of lumber along the center of the flashing. Then reshingle sliding metal step flashing behind the fascia board the trim behind the gutter.

Two ways to flash roof edges. The valley flashing laid over the joint where the two roofs meet should overlap the step flashing at least 2 in. Open valleys have metal flashing to protect this critical area of the roof.
