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. The ridge vent will vary with each job. They are 4' each.

The best method for cleaning a shingle roof using a shingle roof cleaner is to follow the manufacturer's instructions carefully. Typically, this involves diluting the cleaner with water, applying it to the roof surface, letting it sit for a specified amount of time, and then rinsing it off thoroughly with a garden hose or pressure washer. It is important to wear protective gear, such as gloves and goggles, and to work on a cool, overcast day to prevent the cleaner from drying too quickly. Regular maintenance and cleaning can help extend the life of your shingle roof.
The recommended overhang for a roof shingle is typically around 1 to 1.5 inches. This helps provide proper protection for the edge of the roof and also enhances the overall appearance of the roof.
