How to layout a roof for architectural shingles.

When installing shingles start by laying a narrow row of shingles at the bottom of the roof along the edge. When laying the shingles for the top row cut 6 inches 15 2 centimeters from the first shingle in the left corner of the roof using the utility knife. Continue laying down shingles until the row is complete. After that correctly positionthe first shingle and properly snap a line of chalk across the roof to mark the top layer of the shingles.

Mark a chalk on subsequent roof layers upward. Apply the first real course of architectural shingles so that the tabs reach the lower edge of the starter course. Next lay the first full row of shingles so they re directly covering the starter row. You can cut the layered edge of architectural roof shingles and use the cut flat piece as your starter roof single.

This provides a waterproof backing which stops the roof leaking. Place a whole shingle next to it. A starter row is required to prevents water from leaking into the roof from the gaps between the shingles. Before you install your first shingle use your utility knife to cut 6 inches off of the side then lay it on your roof allowing the architectural shingles to hang between 1 2 to 2 inches over the edge.

Place a whole shingle next to this one making sure to nail each shingle to the roof before placing the next. To make sure the fascia is protected always lay the first shingle with a 1 8 inch overhang. Apply a cover of starter architectural shingles. Lay the next row of shingles directly on top of the first row making the row two tiles thick.

Preparing the roof for architectural shingles is the same as for three tab shingles. The ice and water shield is placed on the bottom edge and 15lb felt tar paper is applied to the rest of the roof. It is important to lay a starter strip when you begin. Attach each shingle with three nails one in the center and one each on each side.
