How to roof a house with three tab shingles.

Row 7 begins with a full 3 tab shingle. However shingles are packaged in a way that they are light enough for the average person to carry around. If you are using a power nailer drive nails by squeezing the trigger and bouncing the nailer s tip onto the shingle. Do not fasten the flashing piece to the vertical wall.

As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. The average 3 tab shingle needs four nails per shingle. Use the chalk line to snap a straight line vertically every 6 inches. Place it so the tab of the end shingle covers it completely.

This will allow the flashing piece to move independently of any differential expansion and contraction that may occur between the roof deck and the wall. Repeat this on both sides of the roof. Secure the horizontal flange to the roof deck using two nails. Install a starter course by cutting off the three tabs on a shingle leaving only the top tar section.

Begin row 5 with the 1 tab shingle and row 6 with the 1 2 tab shingle. Use the chalk line to snap a straight line vertically every 6 inches. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. Drive a nail at one end first then drive the others.

Align and install the 2 tab shingle aligned with the next 5 inch higher chalk line. Because the bending can stress and deform shingles especially in cold weather the ends of those shingles may warp over time creating a prominent pattern on the roof. Every 5 inches make a new mark until you get to the rop of the roof. Pattern curling is caused by the roofer having to lift the end tab of every other shingle to install the last shingle nail at the end of the next shingle.

Use your chalk and tape measure to mark about 12 inches up on the roof for the first set of shingles. Using the chalk line snap a straight line on each 5 inch increment. Do this on both sides of the roof. Begin row 4 with a shingle cut in half 1 and tabs and complete that row.
