Instructions

• 1). Put down your starter shingles. Take two shingles and put one at the eaves on each end of the roof. Let these starter shingles hang one inch over the eaves and 1/4 to 3/8 of an inch over the side of the roof.
  
  
• 2). Install the starter shingle row. Put one nail in each starter shingle at the roof's edge. Draw a chalk line between the two starter shingles to use as a guide. Place shingles on the chalk line between the starter shingles. Hammer two nails in each shingle 3/4 of an inch from each edge and three to four inches from the shingle bottom.
  
  
• 3). Apply more shingle rows. Use two nails for each shingle like you did with the starter row. Use a chalk line to keep rows straight. Make sure to leave 1/8 to 1/4 of an inch of space between each shingle. Don't match spaces between rows. Position shingles so that the spaces on one row are 1½ inches away from spaces on the previous row.
  
  
• 4). Cut out shingles for the valley. You'll need to use one shingle as a sample. Put it on the eave in the valley and use your pencil to mark the valley's angle on the shingle. Count the number of shingles you'll need for the valley. Go to your circular saw and cut all valley shingles based on the sample you marked.
  
  
• 5). Install shingles for the valley. Put the one-by in the valley and put valley shingles next to it. Put two nails in each shingle to attach. If a valley shingle overhangs the roof's ridge, put a chalk line on the ridge and the shingle. Score the shingle with a utility knife and push it until it breaks. Throw away the excess and move the one-by.
  
  
• 6). Install roof ridge and hip shingles. These shingles are designed for hips and ridges but are installed the same as other shingles.
