What is a roofing square? Essentially it is 100 square feet or a 10Ã10â² block. Because roofs, siding and other big projects are â¦ well, big, using a square foot as a unit of measurement gets complicated. Also, roofing and siding are a commodity now days, so even if you are off by a few sq. feet, it is fine. Itâs not marble flooring, where each tile costs $20 + installation, and when you are off by 30 sq. feet, you can be down $1000.
If your sending letters to people all over the country, your postage cost will be between 21 cents each and 27 cents each. These bulk mail rates are for letter size mail (up to 6.125 x 11.5 landscape only, if you turn it into a portrait orientation it becomes a flat and your postage will increase).
On Sunday, Jan. 26, the cost to mail a first-class single-piece letter jumped from 46 cents to 49 cents. The U.S. Post Office's 3-cent increase is the largest hike for consumer postage in more than a decade. The cost of mailing a postcard will also go up to 34 cents, a 1-cent increase. The announcement of the increase in postage rates came Dec. 30. The increase will help the budget deficit that the USPS has been dealing with in recent years.
