14 Common Roofing Method Terms

When it comes to putting on a new roof at the Lake of the Ozarks, there are many different methods you can use.  The size and shape of your roof will determine what type of methods will work best. Luckily, you can leave the hard work up to your Lake of the Ozarks roofer! However, it might be nice to check out some of the below methods and terminology so you understand what your roofer is talking to you about.

Roofing Method Terms

• American Method - application of very large individual shingles with the long dimension parallel to the rake.  Shingles are applied with a 3/4-inch space between adjacent shingles in a course. 
• Bridging - a method of reroofing with metric sized shingles. 
• Closed Cut Valley - a method of valley treatment in which shingles from one side of the valley extend across the valley, while shingles from the other side are trimmed two inches from the valley centerline.  The valley flashing is not exposed. 
• Concealed Nail Method - Application of roll roofing in which all nails are driven into the underlaying course of roofing and covered by a cemented, overlapping course.  Nails are not exposed to the weather. 
• Double Coverage - application of asphalt roofing such that the lapped portion is at least two inches wider than the exposed portion, resulting in two layers of roofing material over the deck. 
• Dutch Lap Method - application of very large individual shingles with the long dimension parallel to the eaves.  Shingles are applied to overlap adjacent shingles in each course as well as the course below. 

• Exposed Nail Method - application of roll roofing in which all nails are driven into the cemented, overlapping course of roofing. Nails are exposed to the weather. 
• Low Slope Application - method of installing asphalt shingles on roof slopes between two and four inches per foot. 
• Nesting - a method of re-roofing with new asphalt shingles over old shingles in which the top edge of the new shingle is butted against the bottom edge of the existing shingle tab. 
• Normal-Slope Application - method of installing asphalt shingles on roof slopes between 4 inches and 21 inches per foot.
• Open Valley - method of valley construction in which shingles on both sides of the valley are trimmed along a chalk line snapped on each side of the valley. Shingles do not extend across the valley. Valley flashing is exposed. 
• Racking - roofing application method in which shingle courses are applied vertically up the roof rather than across and up. Not a recommended procedure. 
• Steep-Slope Application (Mansard) - method of installing asphalt shingles on roof slopes greater than 21 inches per foot. 
• Woven Valley - method of valley construction in which shingles from both sides of the valley extend across the valley and are woven together by overlapping alternate courses as they are applied. The valley flashing is not exposed.
