Step 4 valleys.
Flashing on roof lifting.
Make sure that you do not apply the roofing cement along the eaves.
Roof flashing is a thin material usually galvanized steel that professional roofers use to direct water away from critical areas of the roof wherever the roof plane meets a vertical surface like a wall or a dormer.
Use a caulking gun to seal the vent flashing.
Step 5 seal vent flashing.
Apply roofing cement 6 inches from the edge below the shingles.
If you are resealing drip edging seal beneath the shingles but don t seal the drip edge along the eaves.
If you are working with valley flashing lift the edges of the surrounding shingles and spread roofing cement on the flashing about 6 inches in from the edge of the shingles.
Flashing is installed to surround roof features such as vents chimneys and skylights.
It can be made of galvanized steel copper aluminum or even vinyl.
Step flashing should always be used where the roof deck meets a sidewall.
Drip edge the drip edge is flashing that directs water into the gutters.
Seal step flashing with urethane caulking.
While you are up on the roof you should inspect all of the areas so that you don t have to return any time soon.
The flashing is located at intersection points on your roof in spots such as peaks and valleys where water is likely to collect and pool.
Base flashing is installed over underlayment but under siding and shingles so you may not be able to see it from the ground.
You will find it under the shingles running along the peak of a roof but also around chimneys vent pipes and skylights.
Lift the shingles that are near the valley flashing.
This will be placed 6 inches below the shingles and along the drip edge.
