How many shingles do I need for a 4x8 sheet of plywood?

Each plywood sheet is 4 x 8 feet or 32 square feet, which coincidentally is almost exactly equivalent to the coverage of one bundle of traditional three-tab shingles.

Some roofs are easy shapes, like a long gable roof on a bungalow with one big rectangle at the front of the house and a similarly sized one at the back of the house. A simple measurement of the length times the width and you’re done. But then, there are complex roofs with a combination of shapes and planes and surfaces — rectangles, triangles and maybe a trapezoid “for good measure.” Whatever the shape or complexity of your roof, the goal is the same: measure the area of all the surfaces and add them together to get the total area. Another option is to measure your home’s top floor’s square footage or, more correctly, the attic floor area. If you use this method, you’ll need to factor in the slope of the roof. For example, a very steep roof on a 1,000 square foot attic will need more shingles than a lower sloped roof on the same sized attic. Your roofer will know that steeper roofs use more shingles than lower sloped roofs, for the same house size, and there are established slope multiplier factors to make this calculation simple (see Table below). Using this value and allowing for the additional roof area overhangs at the soffit, you can get a decent approximation of the roof area without going on the roof.

Roof Slope

AREA/RAKE CONVERSION* (ROOF PITCH FACTOR) SLOPE (INCHES PER FOOT) AREA/RAKE FACTOR 4:12 1.054 5:12 1.083 6:12 1.118 7:12 1.157 8:12 1.202 9:12 1.250 10:12 1.3052 11:12 1.356 12:12 1.414 To use the table, simply multiply the projected horizontal area by the conversion factor for the appropriate roof slope. The result is the actual area of the roof. With recent innovations in technology, a newer roof measurement option involves satellite and/or drone images, which, when properly calibrated, can yield an accurate roof area measurement. One such service is available through EagleView Technologies. Roofers can use these tools to save time preparing roof area estimates and can even export the information in the form of a job quote to homeowners. Roof areas are generally referred to in the roofing industry using a term called a “square,” which is simply 100 square feet of roof area. While this area can also be measured in metric units (square meters), imperial square foot units are most commonly used and are solely referenced in this blog. Asphalt shingles are typically packaged with this in mind, but if a package of shingles covered an entire 100 square foot square, it would be too heavy to handle. So, most popular shingles are sold such that three bundles are needed to cover one square of roof area. But be careful — not all shingle brands are packaged three bundles to a square! Read the label carefully, as some brands need a bit more than three bundles to cover a square. Specialty shingles, such as IKO Armourshake, are heavier and therefore packaged to cover 20 square feet per bundle, or five bundles per square.

Should I use tongue and groove plywood?

Tongue-and-groove plywood is superior to regular plywood for floor decks because it creates a stronger, more rigid subfloor, and helps eliminate sagging and "bounce" at the seams between the joists. But it is also more difficult to install because the tight-fitting joints don't always go together easily.

Tongue-and-groove plywood is superior to regular plywood for floor decks because it creates a stronger, more rigid subfloor, and helps eliminate sagging and "bounce" at the seams between the joists. But it is also more difficult to install because the tight-fitting joints don't always go together easily. Here's a simple way to close up those joints: Lay a 4-foot-long 2x4 across the joists to protect the plywood edge. Stand on top of the 2x4, then gently rap it with a sledgehammer. If the tongue-and-groove joint doesn't close up, the plywood might be slightly warped. Have a helper stand on the seam to align the tongue with the groove, then rap the 2x4 with the sledge. Once the joint is tight, drive in a couple of screws or nails to hold it, then slide the 2x4 down along the edge of the plywood sheet and repeat the process.
