Stateline shingles are a new and improved shingle. They offer a lifetime warranty; they have 110 miles per hour limited wind warranty. The new Stateline shingles duplicate the rich look of slate tiles that are often very expensive. Also, the large size offered is easier to install and reduces labor for the installer.
For someone who is looking to install the Stateline shingle, you would first use a starter strip for all Stateline shingle projects. Or if you would like, you can trim off 7 ½” of bottom tabs to align the self seal with the eaves. You would then trim 4″ off the rake edge to ensure the first course will overlap the starters. The overhang drip edge should be at 3/8 at both the eave and the rake edges.
Then you would fasten 3″-4″ for the eaves above the self sealant. Continue this across the eave with full length trimmed shingles. Installing the first course of shingles is the next thing to do. You start with a full shingle which gets installed over the starters which needs to be flush at the eave and the rake edges. You will use six fasteners to properly secure the Stateline shingles to the roof.
Fasten 5/8″ above each cut-out with fastening below the self seal and above each cut out. High nailing comes with a precaution though. High nailing reduces any wind resistance and high nailing also can cause shingles to slip off of the roof deck itself. You are to drive the fasteners flush to the shingle, if you over drive the fasteners it can lead to damage to the shingles on the roof. If you under drive the fasteners it can lead to shingle blow-offs during inclement weather.
You are to continue laying the first course of shingles and then start across the eave using full shingles. Also, avoid crowding the shingles, place the shingles close but not too close. Crowding the shingles can cause the shingles to buckle.
Installing the second course of shingles you will trim off 12″ off the rake edge to properly set the design pattern. Align then with the alignment notch of the underlying shingle, giving 3/8″ overhang at rake edge. Align the bottom to the top of cut-outs of the shingle below, these results in a 7 ½” exposure. Avoid over-exposing though. This can result in high nailing and can alter the Stateline pattern.
Finally, fasten in place to secure to the deck and continue this across the eave with full shingles. Following these instructions will make sure that your new Stateline Shingles will last for many years to come.
