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.
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.
13 square. 1 square of shingles is 100sq feet.
There are 3 bundles in a square if you are using 3 tab. 4 bundles if you are using Architectural.
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
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.
How many bundles of 3-Tab Shingles are needed to cover 80 square feet?
3 bundles of shingles per 100 sq ft of roof
certainly, cut them 12" wide
A bundle of 3-tab shingles typically covers about 33.3 square feet. When calculating linear feet for capping, it depends on the length of the roof's edge. Generally, if you're using 3-tab shingles for capping, you would need to determine the total linear feet of the edge to be capped and divide by the coverage per bundle to find how many bundles are required.
A standard bundle of 3-tab shingles typically covers about 33.3 square feet. However, this can vary slightly depending on the manufacturer. It's important to check the specific packaging for precise coverage details.

If you have cut up roof you will need just under 10% for starters and ridge cap. (3 tab) Example a 60 square roof would need 5-6 squares. Lower pitched roofs would of course require less.
