Valley tear-off (metal pan)

Large valley with shingles 
Leaks take place below when the snow and ice accumulates causing ice dams
Water leaks because the shingles are designed to shed the water 
On a steep roof 




Removed the shingles and applied base sheet making sure this turned up against both sides of the valley 

Base sheet was nailed down on both slopes under the shingles .
Galvanized metal pan was installed and fastened in place 
Made sure this metal pan fastened in place before the smooth modified membrane was installed 
Installed the smooth modified membrane followed by the new shingles 
Bottom course of the shingles starts about 10 ft away from the base of the valley 

We also hand sealed the shingles with high grade urethane based caulk to make sure the new shingles are adhered with the existing older shingles and prevent wind damage
