Roof Shingle Installation Patterns

Use 4 nails per shingle and 6 nails on the prevailing windward sides of the roof as wind resistance nailing.

Roof shingle installation patterns.

Other shingle design patterns have come and gone including shingles that once installed simulated the look of fish scales or had interlocking t shapes scalloped and beavertail rounded tabs. Because the bending can stress and deform shingles especially in cold weather the ends of those shingles may warp over time creating a prominent pattern on the roof. If you live in an area with inclement weather you should consider using a special ice and water protector. This article series defines shingle laddering an installation pattern and it explains how to identify evaluate shingles installed in this ladder pattern.

Repeat this basic pattern alternating shingles across the roof working toward the right side using the chalk line to keep the shingles straight horizontally. When installing shingles start by laying a narrow row of shingles at the bottom of the roof along the edge. Continue laying your shingles horizontally up the roof. Check with your roofing dealer to learn about any installation differences.

Work up from the initial row starting at the lower corner in a diagonal pattern staggering the shingles to prevent gaps. Some were even diamond patterned roof shingles.

Most metal shingles will be attached to the roof using metal shingle.

Other composition shingles such as architectural and random cutouts are installed using most of the same techniques. Three tab shingles are still widely available and used. Using your staple gun secure the felt to the roof. The information here describes the various sorts of roof leak wear and cosmetic issues caused by shingle laddering as an example of something a bit less than the.

Lay the starter row of metal shingles at the drip edge and affix to the roof with metal roofing nails. Rather shingle installation patterns are methods of orienting and interlacing roof shingle courses to maintain the offset of joints between shingles in successive courses and to speed production by establishing a regular and predictable installation process.
