Shingle Roof Valley

Water collects in a valley to flow off the roof.

Shingle roof valley.

Woven closed cut and open. Essentially there are three main ways to shingle a roof valley. The valley area of a roof the straight lines formed when two different planes of the roof meet is a critical area that handles a tremendous amount of water run off. One nail goes into the top section of the shingle where it covers the valley metal.

I then move the shingle to the uppermost course on the roof plane line up the mark on the shingle with the valley center and again mark the corner. Place the nails along the edge of the valley metal not into it. From the stepped off main part of the roof run shingles into the valley and cut them square from where the bottom corner intersects with the shingles nailed along the valley line. Your choice of valley installation method is critical because when improperly installed valleys are risks for serious leaks.

To shingle out of the valley with laminated shingles lay a shingle down as a gauge and mark the corner at the bottom left and top right of the roof.
