How Do You Layout A Shingle Roof?
A shingle roof is a type of roof composed of individual shingles laid in rows. The shingles are usually made of asphalt but can also be made of other materials, such as wood or slate. When laying out a shingle roof, starting at the bottom and working your way up is important.
The first row of shingles should be laid, so they overlap the roof’s bottom edge. The second row should be laid so that the shingles overlap the first row by about half. This pattern should be continued until the entire roof is covered.
There are a few different ways to lay out a shingle roof: Size your shingles appropriately, Lay a starting row at the bottom of the roof along the edge, Lay the first row of shingles directly covering the narrow starter row.
Others Lay the second row of shingles, Lay the second row of shingles, Interlace the flashing around the chimney with the rows of shingles, and bring the ridge edges together with a ridge-capping layer.
1. Size your shingles appropriately.
When utilizing the conventional three-tab variety, some roofers like to cut five different sizes of shingles depending on how you organize your rows and courses.
Essentially, you’ll chop off one-half the width of the first tab to begin the first course, adjusting the necessary space to complete each row and shifting the “slots.” Typically, the following cuts are helpful:
- A half-tab for your first-course shingles, please.
- A whole bill for your second-course shingles
- 1.5 shingles off your third course,
- 2 tabs off your shingles’ fourth-course
- Cut half of the final tab for your fifth course.
- Maintain your sixth-course tabs.
2. Lay a starting row at the bottom of the roof along the edge.
Nail the three-tab shingles approximately 3/4 inch (1.8 cm) above the cutouts, near where the tab joins the shingle’s upper half.
However, take care not to nail into the tar strip. In addition, 2 inches from each end of the shingle, align a nail with the other two. In all, four nails should be used per 3-tab shingle.
-Nailing here causes the following shingle to cover the nail heads, allowing the successive rows of nails in shingles always to penetrate and secure the lower row’s top edge (this allows 8 nails to hold each shingle).
-If you fire the nail gun too deeply, almost pressing through the shingles, the nails will rip through and fall free. Reduce the air compressor and gun depth settings.
3. Lay the first row of shingles directly covering the narrow starter row.
Draw a horizontal chalk line across the first row to serve as a guide. Cut six inches off the length of the first starting shingle that is nailed on, then utilize the remainder full size.
By shifting them in this manner, the ends of the first regular row of shingles laid over the beginning shingles will be joined. This is the most basic method of shingle installation, sometimes known as “straight up.”
4 Lay the second row of shingles.
Set the first shingle of the second row back a half tab, or 6 inches (17 centimeters), from the edge of the first shingle on the first row so that the bottoms of its tabs slightly touch the tops of the cutout slots on the shingle below.
This 1/2 tab must be clipped where it hangs off the gable roof’s left edge.
Make a vertical chalk line from the inner edge of the first shingle in the second row to the top of the roof and then from the inside edge of the first shingle to the roof.
These chalk lines will direct the succeeding even-numbered and odd-numbered rows of shingles. Continue working your way up the roof horizontally until you reach the peaks.
5. Lay the second row of shingles.
To prevent sagging, dimpling, splitting, and leaking, you can stick your finger through nail strips of aluminum sheets over holes.
Metal flashing put over tar surrounds stack pipes, vents, and chimneys. This flashing should be interlaced with the shingles, commonly cemented and fastened down under the upper shingles but above the shingles on the sides.
Water will flow down the roof but not through the interlacing. For stacks and vents, the bottom two or three rows that meet the flashing should go under it, while the top rows should go over it.
6. Interlace the flashing around the chimney with the rows of shingles.
Before placing shingles over the chimney flange, cement a sheet metal flashing apron over the upper edge and another over the bottom half.
Then, using asphalt roofing cement, cover the lower apron on each cemented side layer of flashing that tucks under the top apron.
7. Bring the ridge edges together with a ridge-capping layer.
You may either utilize ridge shingles or cut a number of normal shingles into three tabbed, equal pieces, bend each, so it fits snuggly on the roof peak, and nail them into place. You’ll need longer nails for this section since you’ll be driving through more layers of shingles.
