Low slope and steep slope limits for asphalt shingles. Asphalt roof shingle course offset requirements. We describe asphalt shingle nailing type, size, spacing and locations. This article series discusses best roofing practices for the installation of asphalt roof shingles. Roof shingles that are not adequately fastened to a sound roof deck are likely to blow off, as we illustrate in our photo above showing a semi-naked barn roof. Here we describe what can go wrong when using a roofing stapler on asphalt. Use of staples for asphalt shingle installation can work if you work carefully but in my experience you're asking for trouble.

Staplers are widely used in government, business, offices, work places, homes and schools. The word "stapler" can actually refer to a number of different devices of varying uses. In addition to joining paper sheets together, staplers can also be used in a surgical setting to join tissue together with surgical staples to close a surgical wound (much in the same way as sutures). Most staplers are used to join multiple sheets of paper. Paper staplers come in two distinct types: manual and electric. Manual staplers are normally hand-held, although models that are used while set on a desk or other surface are not uncommon. ![]() Electric staplers exist in a variety of different designs and models. Their primary operating function is to join large numbers of paper sheets together in rapid succession. Some electric staplers can join up to 20 sheets at a time. ![]() Typical staplers are a third-class lever. patent 56,587 for a small, bendable brass paper fastener that was a precursor to the modern staple. patent 67,665 for a press to insert the fastener into paper. He showed his invention at the 1876 Centennial Exhibition in Philadelphia, Pennsylvania, and continued to work on these and other various paper fasteners throughout the 1880s. In 1868 an English patent for a stapler was awarded to C. Gould, and in the U.S, Albert Kletzker of St. Heyl filed patent number 195,603 for the first machines to both insert and clinch a staple in one step, and for this reason some consider him the inventor of the modern stapler. In 18 Heyl also filed patents for the Novelty Paper Box Manufacturing Co. Manufacturing Co.'s inventions were to be used to staple boxes and books. The first machine to hold a magazine of many pre-formed staples came out in 1878. On February 18, 1879, George McGill received patent 212,316 for the McGill Single-Stroke Staple Press, the first commercially successful stapler. This device weighed over two and a half pounds and loaded a single 1/2 inch wide wire staple, which it could drive through several sheets of paper. The first published use of the word "stapler" to indicate a machine for fastening papers with a thin metal wire was in an advertisement in the American Munsey's Magazine in 1901. In the early 1900s, several devices were developed and patented that punched and folded papers to attach them to each other without a metallic clip. The Clipless Stand Machine (made in North Berwick) sold from 1909 into the 1920s. It cut a tongue in the paper that it folded back and tucked in. Bump's New Model Paper Fastener used a similar cutting and weaving technology. ![]() In 1941 the type of paper stapler that is the most common in use today was developed: the four way paper stapler. With the four way, the operator could either use the stapler to staple papers to wood or cardboard, or used to staple like pliers for bags, or the normal way with the head positioned a small distance above the stapling plate. The stapling plate is known as the anvil. The anvil often has two settings: the first, and by far most common, is the reflexive setting, also known as the "permanent" setting. In this position the legs of the staple are folded toward the center of the cross bar.
