Roofing in the North vs. Roofing in the South Roofing in the North vs. Roofing in the South The roofing needs of homes in the northern and southern United States vary greatly due to the different climates. In the north, roofs must be able to withstand heavy snowfall and ice dams, while in the south, roofs must be able to withstand high winds and heavy rains. Roofing in the North In the north, it is common to use ice and water shield underlayment on roofs. This type of underlayment helps to prevent water from seeping under the shingles and causing leaks. Ice and water shield is typically applied to the eaves and valleys of the roof, as well as to any other areas that are prone to leaks. Another common practice in the north is to use scaffolding when installing roofing on steep roofs. This is done to ensure the safety of the roofers and to prevent accidents. Scaffolding can be expensive, but it is a necessary safety precaution in areas with steep roofs. Roofing in the South In the south, it is not as common to use ice and water shield underlayment. This is because the climate is not as harsh, and leaks are less likely to occur. However, there are still some areas in the south where ice and water shield is required by code. Scaffolding is also not as common in the south as it is in the north. This is because the roofs are typically not as steep, and there is less risk of accidents. However, some roofers in the south do use scaffolding, especially on large or complex roofs. Other Differences In addition to the use of ice and water shield and scaffolding, there are other differences between roofing in the north and roofing in the south. For example, the type of roofing materials used may vary. In the north, metal roofs are more common than in the south. This is because metal roofs are more durable and can withstand the harsh winter weather. Another difference is the way that roofs are ventilated. In the north, it is important to have adequate ventilation to prevent ice dams from forming. This is done by installing ridge vents and soffit vents. In the south, ventilation is not as important, but it is still a good idea to have some ventilation to prevent moisture buildup. Conclusion The roofing needs of homes in the north and south vary greatly due to the different climates. Roofers in these regions must take these factors into account when designing and installing roofs. By understanding the differences between roofing in the north and roofing in the south, homeowners can ensure that their roofs are properly protected from the elements. Additional Information Here are some additional information about roofing in the north and south: Roof pitch: The roof pitch is the angle of the roof. In the north, roofs typically have a steeper pitch than in the south. This is because the steeper pitch helps to shed snow and ice more effectively. Roof...

Closed-Cut and Long Island Roof Valleys Closed-Cut and Long Island Roof Valleys Article Source: http://www.roofer911.com Article: "Four Ways to Shingle a Valley" Author: Mike Guertin Issue/Date: #152, December 2002/ For the next two shingling methods, closed-cut and Long Island valleys, I work out of the valley using laminated shingles instead of working toward the valley with three-tab shingles. Shingling both a closed-cut valley and a Long Island valley is the same for the first half of the process. Working on the smaller roof plane, I set a shingle on the first course line. I place the shingle so that one edge is 2 ft. away from the valley center at the nail line. I mark the shingle where the valley center crosses the top edge, and I mark the roof at the top outside corner of the shingle. To shingle out of the valley with laminated shingles, lay a shingle down as a gauge and mark the corner at the bottom (left) and top (right) of the roof. I then move the shingle to the uppermost course on the roof plane, line up the mark on the shingle with the valley center and again mark the corner. A chalkline snapped between this mark and the lower mark forms my guide line. After snapping the guide line between marks, install the shingles with one corner on the line. Snap a chalkline 3 in. from the valley, and you're ready to complete the valley. I always weave my first course. But after that I run the shingles up the valley, aligning the top edges with the course lines and the top outside corners with the guide line. I nail the shingles normally, except that I keep nails at least 6 in. away from the valley center. Now I'm ready for the other roof plane. Closed-cut valley -- Even if I work toward the valley with three-tab shingles, cut valleys are faster than woven valleys hands down. With a closed-cut valley, there's no need to shingle the two roof planes at the same time. Plus, cutting the closed-cut valley shingles can happen after the rest of the roof is shingled. I begin the second side (the side that will be cut) by snapping a cutline 2 in. to 3 in. from the valley center. Keeping the cutline away from the center of the valley creates a better watercourse for runoff and tends to hide discrepancies in the line after the shingles are cut. Working out of the valley with the closed-cut method, snap the cutline (left), then step the shingle back from the line to eliminate the need for dubbing the corners. Here, the gauge shingle marks the guide line ( right). Here's one of the big advantages of working out of the valley with laminated shingles. To establish a line to guide the placement of the shingles on the second roof plane, I place the lowest shingle on the course line so that the cutline meets the shingle 2 in. down from the top edge. In this position,...
