Cover the edges of the roof with strips of felt before laying out the final layer.
If you live in an area with inclement weather you should consider using a special ice and water protector.
The shingles are fixed to the roof boards or insulation boards if you have chosen the roof insulation option with clout nails.
Snap a horizontal chalk line over the starting row to use as a guide.
As you work the paper can be tacked down in the center so it won t blow away.
