Complete instructions should be included on the shingle package, but essentially what you will be doing is placing the top of the new shingle against the bottom edge of the old shingle, assuming the exposure of the shingles is the same.
certainly, cut them 12" wide
They are shingles that are thicker than the regular 3-tab shingles, so they stand out better on the roof and create a nicer look. The 'dim' stands for dimensional, as an additional dimension to a flat tabbed shingle.
Cut the shingles into three individual tabs. Center a tab over the peak and put one nail on each side above the tar strip. Lay the next one over it as you would a shingle and continue to the end. On the last one, you will have to surface nail the shingle.
Both 3-tab and Dimensional shingles offer coupons with their packaging. Check on the packages of the shingles themselves at your local Home Depot to find out what savings might be had by using these coupons.
To install 3-tab shingles on a roof, start by preparing the roof deck and ensuring it is clean and free of debris. Next, install a drip edge along the eaves and rakes of the roof. Then, begin laying the shingles starting from the bottom edge, overlapping each row to create a staggered pattern. Secure the shingles with roofing nails and continue this process until the entire roof is covered. Finally, trim any excess shingles and install ridge caps along the peak of the roof for a finished look.

The most common type of roof shingle is asphalt shingles, favored for their affordability, ease of installation, and variety of styles and colors. They typically come in two main types: three-tab and architectural shingles, with architectural shingles offering a more dimensional look and greater durability. Other types of roof shingles, such as wood, metal, and tile, are also available but are less commonly used. Overall, asphalt shingles dominate the residential roofing market.
