To calculate the amount of tar paper needed for a roof, first determine the total square footage of the roof by measuring its length and width and multiplying these dimensions. Then, consider the overlap required between sheets, typically around 2-3 inches, and adjust your calculations accordingly. Finally, divide the total square footage by the coverage area of the tar paper rolls (usually around 100 square feet per roll) to find out how many rolls you'll need. Always round up to account for waste and cuts.

Is felt paper or tar paper reguired on the roof?

Your local building codes will provide what they require. In general on a new roof felt paper is only required for the first 3 feet for a pitch of 6/12. For lower pitch roofs the entire thing should be papered. Most roofers now use a new membrane called "Ice and water shield" for the first 3 feet and recommend using tar paper for the rest of the entire roof. The cost difference for papering the entire roof is minimal and provides much more protection.

Can tar paper be used by itself as a short term roof such as on a concession stand?

Saturated felt paper will quickly weather and begin to tear. There are roofing underlayments that will hold up much longer, but are more expensive. Check with your local building materials center. If by short term you mean 1 to 4 weeks, yeah tar paper is fine. but as the answer above correctly states, it ain't gonna last long. couple weeks max is all that I would trust tar paper, and then it better be fastened down with lath strips or nailed really well.

William Carlos Williams poem-fine work with pitch and copper?

The poem refers to the process of installing or repairing a roof with copper roof tiles, in this case 8 foot long panels. The crevices or joints are joined with pitch, a pine tar extract. The pitch may also refer to tar paper. A copper roof eventually turned an oxidized metallic green which can be seen mostly on public domed structures.
