Do not nail closer than 6 inches to the center of valley. Two nails shall be placed at end of each terminating shingle.

d. Prior to applying shingles on the intersecting roof area, snap a chalk line a minimum 2 inches beyond the center of the valley (the first roof area where shingles have been installed.

e. Install first course of shingles to opposing side. Shingles shall extend over previously installed shingles and beyond the chalk line, so when trimmed, a clean cut edge or line is created. Use care when cutting not to damage underlying shingles.

f. Cut top corner of shingle nearest valley center line 1 inch by 45 degrees prior to installing next shingle course.

g. Set shingle in 3 inch wide troweled application of specified roof cement.

h. Succeeding courses shall be installed as first course.
